Acai berry extract

Tier 3 — weak evidence · Antioxidant · Energy claims · Weight claims

Heavily marketed as a superfood, but NCCIH confirms no definitive evidence acai is more beneficial than other fruits. Antioxidant content is similar to common berries. Multiple FTC enforcement actions against companies making false weight loss claims. Save your money — any mixed berries provide equivalent benefits.

Dose: 500–1,000 mg/day extract; no evidence it is superior to common berries; weight loss claims are false
