    Safety

    Caveats

    Samples were small and industry sponsorship common, and most trials combined oral with topical use so oral-only effects are smaller. Ceiling of 12 mg/day. Antiplatelet and blood-pressure-lowering effects - caution with anticoagulants and antihypertensives. Harmless skin tinting at high doses. Avoid with algae allergy. Not established as safe in pregnancy or breastfeeding.

    Less likely to help if

    Smokers, people with heavy sun exposure, and those with an untreated inflammatory skin condition.
