Safety depends on the full formula

Current and former smokers should avoid the older AREDS formula containing beta-carotene because of increased lung cancer risk; the NEI identifies AREDS2 as the alternative. This concern is about beta-carotene, not evidence that zeaxanthin carries the same risk. 1 2

What did EFSA assess?

EFSA’s 2012 assessment found no safety concern with the proposed synthetic-zeaxanthin use of up to 20 mg daily. Its assessment relied partly on animal toxicology and included uncertainty for missing chronic toxicity data; it is not a recommended intake or proof that higher doses improve vision. 3
