Supplement Reference.

Critical for vision, immune function, and skin/mucous-membrane integrity. Easy to get from food; supplement only when there's a real reason.

The body's master water-soluble antioxidant. Essential for collagen synthesis, immune function, and the regeneration of other antioxidants like vitamin E and glutathione.

Functions more like a hormone than a vitamin. Critical for bone density, immune regulation, mood, and signalling in nearly every tissue in the body.

The body's primary fat-soluble antioxidant. Protects cell membranes and circulating lipids from oxidation. Always take the mixed-tocopherol form.

Tells calcium where to go — into bone and teeth, not into arteries. Essential partner to vitamin D3.

The cofactor for neurotransmitter synthesis — serotonin, dopamine, GABA all need B6 to be made. Often the missing piece in mood, sleep, and PMS.

Essential for red blood cell formation, nerve health, and methylation. Deficiency is common in vegetarians, older adults, and anyone on long-term acid blockers or metformin.

The methyl-donating workhorse of the body. Critical for DNA synthesis, neurotransmitter production, and clearing homocysteine. Methylated form only.

The hair-skin-nails vitamin. Worth supplementing if you're actually deficient or running high-dose ALA (which depletes it); largely a marketing fixture otherwise.

An essential nutrient grouped with the B-vitamins. Builds cell membranes, makes the neurotransmitter acetylcholine, and prevents fatty liver. Most people are short.

A quasi-B-vitamin that acts as a second messenger for insulin and serotonin signalling. Most evidence-backed natural intervention for PCOS, and a sleeper for anxiety.

The myo-inositol with 6 phosphate groups. A natural iron chelator with surprising anti-cancer and bone-density evidence.

In 42% of hangover products, and in almost none of them is it doing anything. Genuinely vital for people who drink heavily and chronically — irrelevant to a single rough morning.

The single most useful mineral supplement for most people. Calms the nervous system, improves sleep, relaxes muscles, and underpins 300+ enzymatic reactions.

Critical for bone, but get it from food rather than pills. Calcium supplements carry cardiovascular risk that food calcium doesn't.

Critical for immune function, testosterone, wound healing, taste, smell, and skin. One of the most consistently under-consumed minerals, especially in plant-heavy diets.

Only supplement if you've tested low. Iron is essential, but supplementing without need causes oxidative stress and GI misery.

Essential for thyroid hormone synthesis. Most people get enough from salt or seafood, but those who don't are genuinely deficient.

Essential trace mineral. Drives glutathione peroxidase, supports thyroid hormone conversion, and regulates immune tone. A few Brazil nuts a week often does the job.

Essential trace mineral that's easy to overlook — until you've taken high-dose zinc for a few months and depleted it. Required for iron metabolism, collagen cross-linking, and energy production.

Essential trace mineral for bone matrix, antioxidant defence, and blood sugar control. Most people get plenty from food — supplementation is rarely needed.

A trace mineral that potentiates insulin's action. Helpful for blood sugar control and reducing sugar / carb cravings — particularly in those with documented insulin resistance.

The mineral most Americans dramatically under-consume. Critical for blood pressure, muscle function, and electrolyte balance. Food-first; supplements are dose-capped for safety reasons.

Cheap baking soda. Acutely buffers lactic acid build-up — proven ergogenic for high-intensity efforts of 1–10 minutes.

An under-appreciated trace mineral. Supports bone density, raises free testosterone modestly, lowers SHBG, and reduces inflammatory markers.

Trace lithium — a fraction of the prescription dose used in bipolar disorder, but enough to support mood, cognition, and possibly neuroprotection long-term.

An overlooked trace element required for collagen cross-linking and bone matrix formation. The 'hair, skin, nails' mineral.

A bone-mineral cousin to calcium. Strontium ranelate (Rx in Europe) was withdrawn for cardiovascular concerns; strontium citrate (OTC) is still used for bone support with caution.

Highly porous carbon that binds toxins and gas in the gut. Hospital-standard for acute poisoning; supplemental use for bloating and occasional detox.

An absorbent volcanic clay that binds positively-charged toxins, heavy metals, and bacteria in the gut.

A microporous mineral with a cage-like structure that binds heavy metals and ammonia. Marketed heavily for detox; evidence is limited.

Sodium is the one that matters, and it's the one most 'electrolyte' products under-dose in favour of a long label. Fixes a real part of a hangover — just not the part that makes you feel worst.

The most-studied performance supplement on earth. Builds strength and lean muscle, supports brain energy under stress, and is increasingly used for cognitive support in women and older adults.

The simplest amino acid does an outsized amount of work. Improves sleep by dropping core temperature, supports collagen, calms the nervous system, and may extend lifespan.

The amino acid in green tea that creates calm focus. Fast-acting (30–60 min), non-sedating, takes the jitter out of caffeine.

An overlooked amino acid that may be one of the most important. 2023 research showed taurine supplementation extended lifespan in middle-aged mice — and human levels predict healthy aging.

The most direct glutathione precursor. Hospital-grade antioxidant used for acetaminophen overdose, with emerging uses in mental health, fertility, and longevity.

A direct methyl donor that lowers homocysteine, supports liver function, and provides a modest but real boost to strength and power output.

The direct precursor to dopamine, norepinephrine, and adrenaline. Shines under stress and sleep deprivation — restores cognitive performance when catecholamines are depleted.

The full upstream precursor to serotonin and melatonin. Gentler than 5-HTP — the body converts as needed rather than flooding the system.

The direct serotonin precursor, one step away from the neurotransmitter itself. Faster and stronger than tryptophan, but with more caveats — use carefully.

The primary fuel for the cells lining your gut. Heals leaky gut, supports immune function, and aids recovery from intense training.

Shuttles fatty acids into mitochondria where they're burned for energy. Useful for fat metabolism, exercise recovery, and (the acetyl form) brain energy.

A precursor to carnosine, the muscle buffer that delays fatigue. The supplement that gives you the tingles — and modest but real performance gains.

A leucine metabolite that reduces muscle breakdown. Most useful in catabolic states — illness, aggressive caloric restriction, older adults losing lean mass.

Branched-chain amino acids (leucine, isoleucine, valine) — the muscle-building amino acids. Mostly redundant if you eat enough complete protein; useful in specific cases.

The most abundant protein in the body, the structural matrix of skin, joints, tendons, bone, and gut. Endogenous production drops ~1% per year from your 20s.

Binds acetaldehyde directly, and has the only positive randomised trial aimed squarely at hangover symptoms — from nineteen men, with p-values that sit right on the line.

The most studied protein supplement there is — fast-digesting, leucine-rich, and the simplest way to close a daily protein gap. Not magic; just convenient food.

A pea-and-rice blend closes the amino-acid gaps each has alone and matches whey for muscle when you take a slightly bigger scoop.

The slow half of milk protein — it gels in the stomach and drip-feeds amino acids for hours, which is why it's the classic pre-bed protein.

The most evidence-backed nutritional supplement on the market. Anti-inflammatory, cardioprotective, neuroprotective — and almost everyone is under-eating it.

Omega-3s in phospholipid form — better absorbed than standard fish oil and bundled with astaxanthin and choline. Premium price, premium delivery.

A traditional three-in-one: omega-3 EPA+DHA, vitamin D, and vitamin A from the liver of cod. Particularly useful for those who already need D and A.

An omega-6 that actually reduces inflammation. The exception to the 'reduce omega-6' rule — used for PMS, eczema, dry eye, and joint inflammation.

Medium-chain triglycerides — fats that bypass normal digestion and go straight to the liver, where they become ketones for quick brain energy.

An odd-chain saturated fatty acid that may be the first essential fatty acid identified in 90 years. Emerging evidence; not yet established.

The active compound in turmeric. One of the most evidence-backed natural anti-inflammatories — but only in bioavailable forms. Plain turmeric powder barely absorbs.

A bioflavonoid that calms allergic and immune responses, acts as a mild senolytic, and serves as a zinc ionophore — helping zinc get into cells where it does its work.

The body's master antioxidant. Most oral forms barely absorb — the trick is in the delivery (liposomal, S-acetyl, IV, or build it from precursors).

A unique antioxidant — works in both water and fat compartments, regenerates other antioxidants, and improves insulin sensitivity. Best evidence is in diabetic neuropathy.

The famous red-wine compound. Activates sirtuins, supports cardiovascular function, and (the Sinclair theory) helps NMN do its longevity work.

The most-studied natural senolytic — a compound that selectively kills senescent 'zombie' cells. Pulsed protocols are how it's usually run.

The main bioactive in green tea. Powerful antioxidant with metabolic and cancer-prevention signals — but high-dose extracts carry real liver risk.

The most potent natural Nrf2 activator known — switches on the body's master detoxification and antioxidant defence program. Derived from broccoli sprouts.

An exceptionally potent antioxidant — the red pigment that turns salmon and flamingos pink. Best evidence is for skin UV protection and eye health.

A unique sulfur-containing antioxidant the body has a dedicated transporter for — suggesting it's important. Concentrated in mushrooms; depleted with age.

A standardised French maritime pine bark extract with unusually good trial coverage for endothelial function, venous insufficiency and skin microcirculation — expensive, but genuinely studied.

A cheap, well-tolerated source of oligomeric proanthocyanidins with a small but consistent blood-pressure effect and decent evidence in venous insufficiency.

The flavonoid in more than half of all hangover products. Convincing in rodents, thin in humans — and it targets acetaldehyde, which the newer evidence suggests isn't what actually makes you feel terrible.

The spark plug of cellular energy production. Depletes with age and with statin use — the most evidence-backed mitochondrial supplement.

A direct precursor to NAD+, the coenzyme that powers DNA repair, sirtuin signalling, and mitochondrial energy. NAD+ falls ~50% by age 60 — NMN attempts to restore it.

The other major NAD+ precursor. Better-studied than NMN in humans, with patent-protected purity (Niagen / Tru Niagen), but slightly less direct conversion.

The no-flush form of vitamin B3. Cheap NAD+ precursor, evidence-backed for skin cancer prevention, and a quiet workhorse for joint and bone support.

The only known supplement to trigger mitochondrial biogenesis — the production of new mitochondria. The natural complement to CoQ10.

Triggers mitophagy — the cell's housekeeping process that clears out damaged mitochondria. The first supplement with proper RCT evidence for measurably better muscle function in older adults.

A Krebs cycle intermediate that animal data suggests extends lifespan and healthspan. Levels drop with age; supplementation restores some of what's lost.

A sugar that's directly used to rebuild ATP. Useful in conditions of energy depletion — fibromyalgia, CHF, post-exercise recovery — less so for healthy people.

An old dye repurposed as a mitochondrial-electron carrier. Improves cellular oxygen utilisation; turns urine and tongue blue. Take very seriously and at low dose.

The body's most abundant adrenal hormone and a precursor to both testosterone and estrogen. Levels drop sharply with age — replacement is increasingly common.

A DHEA metabolite that doesn't convert to testosterone or estrogen. Mild metabolic / thermogenic effects without DHEA's hormonal side effects.

The 'mother hormone' — the upstream precursor to DHEA, progesterone, cortisol, testosterone, and estrogen. Strongest noted effects are on cognition and mood.

Shifts estrogen metabolism toward the protective 2-hydroxy pathway and away from the proliferative 16-hydroxy pathway. The estrogen-balance supplement.

Supports the body's ability to actually excrete used estrogens (and other toxins) by inhibiting beta-glucuronidase — the enzyme that 'reactivates' compounds the liver wanted to get rid of.

The upstream precursor to DIM. Converts to DIM (and a few other compounds) in the stomach. Less efficient than direct DIM but cheaper.

The most evidence-backed adaptogen. Lowers cortisol, blunts stress reactivity, improves sleep, and modestly raises testosterone in men.

The acute-stress adaptogen. Where ashwagandha takes weeks to feel and works on chronic stress, rhodiola works within hours and is better for energy, focus, and mental endurance.

The original 'adaptogen' — the herb that gave the category its name. Mild stimulant-free energy support and immune resilience under chronic stress.

The 'true' ginseng. Warming, stimulating, classical TCM use for vitality. Modest cognitive and erectile function benefits in trials.

The 'incomparable one' in Ayurveda. Gentle adaptogen with strong evidence for cortisol reduction, anxiety, and mild blood sugar support.

A classical Chinese adaptogen with the unusual property of supporting both energy and calm. Strong liver-protective evidence; popular in Russian and Chinese clinical use.

A central TCM tonic herb with strong immune-support and emerging telomere / longevity research (Astragaloside IV / TA-65).

A Peruvian Andean root used as both food and medicine. Best evidence is for libido (men and women) and modest mood / energy support — without hormonally manipulating anything.

A blackish resin oozing from Himalayan rocks — humic / fulvic acids, mineral-rich. Modest testosterone, energy, and mitochondrial support.

An Ayurvedic herb that genuinely improves memory and learning — but takes 8–12 weeks of consistent use to feel anything.

An ancient tree extract with one core mechanism: improved blood flow, especially to the brain. Best evidence is in mild cognitive impairment and dementia.

A phospholipid that makes up cell membranes — especially abundant in the brain. Reduces evening cortisol, supports memory, and is one of the few supplements with an FDA-allowed cognitive claim.

More than a kitchen herb. Standardised sage extracts modestly improve memory and reduce menopausal hot flashes.

Another culinary herb with cognitive bona fides. Just smelling rosemary essential oil measurably improves memory. Oral extracts add antioxidant and anti-inflammatory effects.

The classic European sleep herb. Smells terrible, works gently. Best for sleep onset and mild generalised anxiety.

A gentle anxiolytic herb that works through GABA — useful for mild generalised anxiety and as a pre-bed sleep support.

The same plant that flavours beer. Sedating bitter compounds (lupulin) modulate sleep and calm — most often combined with valerian.

A bright, lemony mint with quiet but real calming and cognitive effects. Useful for daytime anxiety without sedation.

Two different herbs sharing a name. American skullcap is a gentle nervine for anxiety; Chinese skullcap (Scutellaria baicalensis) is a powerful anti-inflammatory with cancer-adjunct research.

A chamomile-derived flavonoid that's the cleanest sleep aid in the pre-bed stack. Mildly sedating without grogginess; also a CD38 inhibitor (slows NAD+ degradation).

Naturally rich in melatonin and anti-inflammatory anthocyanins. Useful for sleep, exercise recovery, and joint pain. Drink it as juice or take an extract.

A plant alkaloid that lowers blood sugar and lipids about as well as metformin in head-to-head trials. The most evidence-backed natural metabolic supplement.

The 'sugar destroyer.' Chewed before eating, it temporarily blocks the ability to taste sweetness — useful for breaking sugar habits. Also genuinely supports blood sugar control.

A traditional Asian vegetable used for centuries in diabetes management. Reasonable evidence for modest blood sugar improvement.

A Filipino leaf extract whose corosolic acid mildly mimics insulin. Useful adjunct in blood sugar management; lacks the GI burden of berberine.

The 'true' cinnamon. Modest blood sugar effects; far safer than cassia cinnamon (the cheap supermarket kind), which contains liver-toxic coumarin.

A culinary spice with three distinct supplemental uses — blood sugar, testosterone support in men, and milk supply in nursing mothers.

A folk staple with surprisingly solid evidence for post-meal glucose blunting. Take a tablespoon in water before carb-heavy meals.

A soluble fibre that swells in the stomach to ~50x its dry volume. The most evidence-backed natural appetite-suppressant fibre.

Frankincense extract. Inhibits 5-LOX (a different inflammation pathway than NSAIDs target), making it especially useful for joint pain and inflammatory bowel disease.

The single best evidence-backed natural anti-nausea agent. Pregnancy morning sickness, motion sickness, chemo nausea, post-op nausea — all respond.

The compound that makes chillies hot. Mild thermogenic / metabolic effects orally; potent topical pain relief in standardised creams.

A Southern African desert plant whose root extract is well-studied for back and joint pain. Comparable to mild NSAIDs in some trials.

The plant aspirin originally came from. Salicin-rich bark for pain and inflammation — gentler on the stomach than aspirin, with similar bleeding caveats.

The liver herb. 2,000 years of European folk use; modern evidence supports its role in protecting and regenerating liver cells.

The garden weed that's a long-time European liver herb and gentle natural diuretic. Cheap, easy, mild — quietly useful.

A bittersweet root used in Western and Asian herbalism for liver / skin / detox support. Gentle, food-adjacent, modest effects.

Stimulates bile flow and helps with functional indigestion, especially fat-related. Modest cholesterol-lowering effects too.

A bile acid that thins bile, protects liver cells, and reduces endoplasmic reticulum stress. Useful for cholestasis, liver protection during oral compounds, and gallbladder support.

Enteric-coated peppermint oil is among the best evidence-backed treatments for IBS symptoms. Bypasses the stomach to act on the lower gut.

One of the most evidence-backed cardiovascular supplements. Lowers blood pressure, modestly improves lipids, and reduces arterial plaque progression.

The traditional heart herb of European folk medicine. Modest but real benefit in mild heart failure and as a gentle cardio-tonic.

A tart, ruby-red flower tea that lowers blood pressure as effectively as some first-line antihypertensives at modest doses.

Naturally rich in dietary nitrate, which the body converts to nitric oxide — boosting endurance and lowering blood pressure within hours.

The Italian citrus's polyphenol-rich extract lowers LDL cholesterol and triglycerides comparably to mild statin doses — without the muscle pain.

Rice fermented with red yeast contains monacolin K — chemically identical to lovastatin. Effective for cholesterol; carries the same risks as a statin.

Standardised oleuropein from olive leaves. Modest blood pressure reduction, antiviral / antimicrobial action, and antioxidant support.

The cold-and-flu herb. Real but modest reductions in respiratory infection rate and duration when taken early — quality varies wildly between products.

An Ayurvedic and TCM bitter herb with the strongest evidence of any single herb for shortening colds. Used clinically in Scandinavia.

A dark purple berry traditionally used for colds and flu. Multiple trials show meaningful shortening of flu duration when taken at onset.

A North American root rich in berberine — used as a short-term antimicrobial for gut infections, mouth sores, and sinusitis. Overharvested in the wild.

A Peruvian vine traditional for immune support and inflammation. Modest evidence for rheumatoid arthritis and immune modulation; classic Amazon herbal medicine.

European blueberry cousin with anthocyanins concentrated for eye health and microcirculation. WWII pilot lore aside, real benefits for venous insufficiency and eye fatigue.

The classic women's hormone herb. Raises progesterone (indirectly), normalises menstrual cycles, and is the most evidence-backed natural intervention for PMS and PMDD.

An isoflavone-rich plant used for menopausal symptoms. Real phytoestrogenic activity — gentler than HRT, real benefits for some.

Often marketed as 'natural progesterone' — but the body doesn't actually convert wild yam to hormones. Real effects are mild, anti-inflammatory and symptomatic.

A Southeast Asian root traditional for vitality. Modestly raises free testosterone (mostly by lowering SHBG and cortisol), supports libido, and reduces stress markers.

A West African shrub used traditionally for libido. Animal data shows striking testosterone-raising effects; human evidence is still very thin. Often stacked with tongkat ali.

Traditional Ayurvedic and TCM herb sold for testosterone — but RCTs don't show testosterone elevation. Real effects are on libido and sexual satisfaction (probably via different mechanisms).

A wild-harvested male pollen rich in plant phytoandrogens. Traditional Chinese tonic with anecdotal testosterone-supporting reputation; clinical evidence thin.

The men's prostate / hair herb. Modest 5-alpha-reductase inhibition — fewer effects than finasteride, but without the sexual side-effect risk.

Modulates SHBG (sex hormone binding globulin) — making more free testosterone bioavailable. Also a moderate prostate herb (often combined with saw palmetto).

An African plum tree bark used in European clinical practice for BPH. Decent evidence for urinary flow improvement, especially combined with saw palmetto and nettle root.

A simple sugar that prevents E. coli from sticking to the bladder wall. One of the most effective non-antibiotic interventions for recurrent UTIs.

The classic UTI-prevention berry. Works through proanthocyanidins (PACs) that prevent E. coli adhesion — the same principle as D-mannose, by a different mechanism.

An Ayurvedic root that raises cAMP — supports body composition, cardiac function, and hormone signalling. Best evidence in body fat loss.

An alpha-2 antagonist from West African yohimbe bark. Strong fat-loss and erectile effects — and an equally strong cardiovascular and anxiety side-effect profile. Use very carefully.

A triterpene-rich herb with real evidence for venous insufficiency and connective tissue — it stimulates collagen synthesis and strengthens vein walls, which is why it appears in cellulite and scar protocols.

The best single trial in the hangover category, and the only one that targets what the newer mechanism work actually implicates: it cut CRP by 40% and halved the odds of a severe hangover — taken five hours before you drink.

The brain mushroom. Stimulates Nerve Growth Factor (NGF) and BDNF — supports cognition, mood, and (uniquely) peripheral nerve regeneration.

The 'mushroom of immortality' in Chinese medicine. Calms the nervous system, supports sleep, modulates immune function, and gently supports the liver. Take at night.

The energy mushroom. Used by Chinese olympians and Sherpas — modestly increases VO2max, supports endurance, and lifts libido.

The 'king of mushrooms' in Russian and Siberian folk medicine. Highest antioxidant load of any mushroom and a long traditional use for immune and gut health.

The most rigorously studied mushroom for cancer adjunct treatment. Active compounds (PSK, PSP) are licensed cancer adjuncts in Japan.

The 'dancing mushroom.' Polysaccharide-rich, with the best evidence for immune support, blood sugar control, and cancer-adjunct use of any culinary mushroom.

The world's most popular culinary mushroom. Contains lentinan — a beta-glucan that's a licensed cancer adjunct in Japan — plus eritadenine, a natural cholesterol-lowering compound.

A concentrated, partially digested shiitake-mycelium extract. Strongest single-supplement evidence for HPV clearance and one of the better immune-modulating supplements with hospital use.

The 'beauty mushroom.' A jelly-textured Chinese fungus traditionally used for skin hydration — its polysaccharides hold water like hyaluronic acid.

Live bacteria that colonise the gut transiently. Most benefit comes from strain-specific use cases — generic 'probiotic' isn't a single intervention.

The most-studied single probiotic strain on earth. The go-to for antibiotic-associated and traveler's diarrhea.

A species we co-evolved with that's been disappearing from modern guts. Specific strains have strong evidence for infant colic, oral health, and mood.

A probiotic yeast (not bacteria) — which is exactly why it works alongside antibiotics. The most evidence-backed prevention for C. difficile and antibiotic-associated diarrhea.

A keystone gut bacterium that maintains the mucus layer protecting your gut wall. Low levels predict obesity and diabetes; supplementation improves metabolic markers.

Bacillus-strain probiotics that survive stomach acid and travel well — no refrigeration needed. Especially good for travel and people with histamine sensitivity.

The food that feeds your gut bacteria. The other half of the probiotic equation — and arguably more important than the probiotic itself.

Starch that resists digestion in the small intestine and ferments in the colon, producing butyrate — the primary fuel for your gut wall cells.

Soluble polysaccharides from yeast, oats, and mushrooms. Distinct uses: yeast for immune priming, oat for cholesterol, mushroom for immune modulation.

The first milk a cow produces after birth — packed with immunoglobulins, growth factors, and lactoferrin that support gut barrier and immune function.

An iron-binding immune protein found in colostrum, breast milk, and saliva. Manages iron, kills pathogens, modulates immunity — and improves iron status without iron's GI side effects.

A pineapple-derived enzyme with two distinct uses: taken with food it digests protein; taken between meals it reduces inflammation, swelling, and bruising.

A proteolytic enzyme that breaks down dead and inflammatory tissue — used for sinus congestion, post-surgical recovery, and theoretically arterial plaque.

A fibrin-dissolving enzyme from fermented soybeans (natto). Modestly lowers blood pressure, dissolves abnormal clots, and — at high doses — has shown carotid-plaque and cholesterol reduction in trials. The catch: the dose does the work, and typical capsules are far too small.

The best-known systemic enzyme blend — serrapeptase, nattokinase, lipase and proteases in one capsule, widely recommended as an upgrade on plain nattokinase. It is a proprietary blend, which is the whole problem: the one number that mattered in the nattokinase trials is the one the label doesn't tell you.

Multi-enzyme blends that help break down protein, fat, carbs, and fibre. Useful for people with insufficient pancreatic output, gastritis, or chronic bloating.

Supplements low stomach acid — addressing one of the most overlooked causes of indigestion, bloating, and reflux symptoms (paradoxically, low acid often presents as reflux).

An amino sugar the body uses to build cartilage. Modest joint-pain benefit, mostly in moderate-to-severe osteoarthritis — and a surprise longevity signal.

A major structural component of cartilage. Best evidence is in combination with glucosamine for knee osteoarthritis.

The molecule that fills the spaces between your cells with water. Used orally for skin hydration, joints, and dry eye — with surprisingly good evidence.

A completely different mechanism from collagen peptides. Tiny daily doses (40 mg) of undenatured type II collagen retrain the immune system to stop attacking joint cartilage.

The thin membrane between the eggshell and egg white — concentrated source of collagen, glycosaminoglycans, and other joint-supportive molecules. Small dose, real effect.

Dense, nutrient-rich blue-green algae — high-protein, packed with B vitamins, iron, and phycocyanin. Best evidence is in lipid lowering and allergic rhinitis.

A single-celled green algae used for heavy metal binding and elimination. The most evidence-backed natural chelator for mercury and lead.

The microalgae at the base of the entire ocean food chain. Dense in trace minerals, EPA, and bioavailable nutrients — though clinical evidence is thin compared to spirulina / chlorella.

A red seaweed surging in popularity. Real mineral and iodine content; the broader 'cures everything' wellness marketing far exceeds the evidence.

The single most evidence-backed topical for skin aging and acne. Decades of RCT data — nothing else comes close.

Morning antioxidant defence and gradual brightening. Pair with SPF — vitamin C amplifies sunscreen's protection against UV damage.

The all-rounder. Reduces redness, smooths texture, fades pigmentation, supports skin barrier, and pairs with nearly everything. Boring in the best way.

A water magnet for skin. Pulls and holds moisture in the upper layers, giving immediate plumping and a softer look. Pairs with everything.

Magnesium chloride applied to skin. Useful for cramps, post-workout muscles, and as a way to top up magnesium without GI side effects.

Melatonin isn't just for sleep — applied to skin overnight, it's a potent antioxidant that protects against UV-driven oxidative damage from the previous day.

A fat-soluble antioxidant that sits in skin mitochondria and protects against UV-driven oxidative damage. Modest standalone effect, useful in stacks.

Skincare's newest darling — NAD-precursor serums based on the idea that boosting cellular NAD+ in skin reverses age-related decline. Early data, big claims.

A copper-peptide that signals skin remodeling, collagen production, and follicle activation. One of the most evidence-backed topical peptides.

A skin-brightening antioxidant. Widely used in Asia for skin lightening; useful for hyperpigmentation and as part of antioxidant stacks.

A lightweight, non-comedogenic oil that mimics skin's natural sebum. The 'safe' moisturiser — almost no one reacts to it.

Plant-derived ceramides — the lipid building blocks of skin's barrier layer. Oral phytoceramides (from wheat or rice) improve skin hydration from within; topical ceramides reinforce barrier from without.

A polyamine that triggers autophagy — the cellular recycling process linked to longevity. Mouse and human observational data are striking.

A trace amine that the brain produces naturally — the 'love molecule' in chocolate. Acute mood and focus lift, but the effect is fleeting (minutes).

A caffeine cousin from the kucha tea plant. Longer-lasting, less jittery, and (unusually) doesn't build tolerance over weeks.

An amine that the brain uses to support acetylcholine production. Cult-status nootropic from the 1970s; modest cognitive effects and some skin-firming evidence topically.

An arginine metabolite that modulates NMDA, opioid, and nitric-oxide pathways. Modest pain, mood, and neuroprotection effects.
