Everything Vyvata knows about this product — the score, the evidence, the FAQ, and where else to find shopper reviews. No hidden data. Every vendor is scored on the same published rubric — no brand can pay for placement. Read the rubric →
Acai berry has strong antioxidant chemistry (high ORAC) but the human clinical evidence is minimal — most acai supplement marketing rests on preclinical antioxidant data and one small (Udani 2011) pilot at 100 g of pulp daily, far more than any capsule can deliver. 400 mg of a whole-berry powder is essentially a token dose relative to studied whole-fruit intakes. No specific standardization disclosed. Would move to Standard 60+ with anthocyanin standardization at a functional dose.
The Vyvata score's Evidence dimension measures the quality of published RCT support for a product's active ingredients at the label dose. Our source hierarchy: double-blind RCTs in MEDLINE-indexed journals > single-blind RCTs > open-label trials > observational studies > mechanism papers > N=1 case studies (anecdotes). Predatory journals and manufacturer-authored studies without independent replication are weighted down.
Product-specific evidence citations for this item are embedded in the analysis text on the "Analysis" tab. For the full framework and evidence hierarchy, see the methodology page.

No specific standardization disclosed. Would move to Standard 60+ with anthocyanin standardization at a functional dose.
Strongest: Safety at 65/100 (adverse-event profile, interaction risk, and dose ceiling) and Manufacturing at 55/100 (third-party testing, GMP compliance, and facility audit status). Weakest: Formulation at 50/100 (dose adequacy, bioavailability form, and ingredient redundancy) and Evidence at 45/100 (quality of published RCT support for the active ingredients at the label dose). All six dimensions feed the overall Vyvata score; a weakness on any one dimension pulls the overall down proportionally.
No third-party certifications (NSF, USP, ConsumerLab, or equivalent) were on record at the time of scoring. This affects the Manufacturing dimension score. The manufacturer may test internally or have obtained certification more recently — check the current product label for the most up-to-date information.
Would move to Standard 60+ with anthocyanin standardization at a functional dose.
