Oxidized LDL (oxLDL)

Specialist

also oxldl

What it isA subset of LDL particles whose lipid and protein components have been chemically oxidized by reactive species. Once oxidized, LDL becomes a potent inflammatory trigger.

DoesOxidized LDL is taken up by macrophages in the vessel wall to form foam cells — the cellular kernel of atherosclerotic plaque.

GoodLow oxLDL suggests low oxidative burden and minimal active atherogenesis.

BadElevated oxLDL signals active plaque biology and predicts cardiovascular events independently of LDL-C.

Standard

<60 U/L.

Optimal

20–45 U/L (lower is good)

Modifiers

Rises with smoking, high blood sugar, polyunsaturated fat oxidation, low antioxidant status.

How to optimize

Lifestyle: Quit smoking, Zone 2 cardio, weight loss; minimize fried foods and reused cooking oils.
Diet: Mediterranean pattern; cut seed oils and ultra-processed food; polyphenol-rich foods (berries, olive oil, dark leafy greens, green tea); avoid oxidized cooking oils.
Supplements: Mixed tocopherols (200 IU/day), vitamin C (500–1000mg/day), CoQ10 (100–200mg/day), curcumin (500mg 2×/day), polyphenols (resveratrol, quercetin).
Peptides: —
Drugs: Statins reduce oxLDL by lowering LDL particles available for oxidation.
