Mixed carotenoids

Tier 3 — weak evidence · Antioxidant · Eye health · Skin

A blend of beta-carotene, lycopene, lutein, and zeaxanthin mimicking the carotenoid profile of colourful vegetables. Isolated beta-carotene caused harm in smoker trials but mixed carotenoids from food are associated with health benefits. Avoids single-carotenoid risk while providing broad antioxidant coverage. Generally very safe.

Dose: 15–25 mg/day mixed carotenoids from natural sources; safer than isolated beta-carotene supplementation
