Forever Fields of Greens is a greens-powder / green-food blend that markets itself explicitly as a way to 'cleanse and detoxify.' This triggers the unverified_medical_claim autofail: no supplement has been shown in peer-reviewed RCTs to 'cleanse' or 'detoxify' a healthy human body — the liver and kidneys perform detoxification, and no greens formula changes that (Klein 2014 review of detox diets). The underlying ingredients (alfalfa, barley, wheatgrass) are nutrient-dense but unremarkable at typical scoop doses. MLM markup compounds the problem. Would only exit Rejected with the detox/cleanse language removed and honest positioning as a low-dose greens supplement.
Auto-fail rule triggered: Unverified medical claim.
A specific medical or physiological benefit claim on the label or marketing is not supported by published clinical evidence in humans. Distinct from disease claims — this covers narrower physiological claims (e.g. 'increases NAD+ by X%', 'boosts immunity') without published RCT support at the actual product dose and formulation. See the full rubric →
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.

Strongest: Manufacturing at 55/100 (third-party testing, GMP compliance, and facility audit status) and Safety at 50/100 (adverse-event profile, interaction risk, and dose ceiling). Weakest: Transparency at 40/100 (dose disclosure vs proprietary blends, and honesty of marketing claims) and Evidence at 35/100 (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.
This product triggered the Vyvata auto-fail rule "unverified_medical_claim", which places it in the Rejected tier regardless of its scores on other dimensions. See the full explanation above and the methodology page for the current list of auto-fail rules.
