What it isCarotenoids are a family of plant pigments — beta-carotene, alpha-carotene, lycopene, lutein, zeaxanthin — that the body partially converts to vitamin A and uses as antioxidants.

DoesProvide antioxidant protection in plasma and tissues; support eye, skin, and immune health; some converts to vitamin A.

GoodMid-high carotenoid levels reflect a colorful plant-rich diet and predict lower cardiovascular and cancer mortality.

BadLow carotenoids suggest a low plant intake. Very high beta-carotene from supplementation in smokers paradoxically increases lung cancer risk.

Standard

10–85 µg/dL.
