Why this scored 38/100
Evergreen Apothecary PCOSync Tincture is explicitly positioned for polycystic ovary syndrome (PCOS) and PCOS-related symptoms (menstrual regularity, hormonal balance). PCOS is a defined medical diagnosis (Rotterdam criteria: oligo/anovulation, hyperandrogenism, polycystic ovarian morphology on ultrasound — 2 of 3) with real complications (metabolic, cardiovascular, endometrial cancer risk). Marketing a herbal tincture specifically for a named medical condition triggers unverified_disease_claim under FTC and Vyvata rubric. The evidence-based interventions for PCOS include: myo-inositol + D-chiro-inositol at 4 g myo + 100 mg DCI (Nordio 2019, Facchinetti 2015) for insulin sensitivity and ovulation; metformin for insulin sensitivity; spironolactone for androgen excess; combined oral contraceptives for cycle regularity; and lifestyle intervention (weight management improves outcomes at 5-10% loss per Legro 2013). Botanical tinctures with unspecified ingredients do not have RCT evidence approaching these interventions. Rejected under unverified_disease_claim.

Evidence & sources
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.
How to read the Evidence dimension
- 80–100: Multiple double-blind RCTs in indexed journals directly testing this product OR the exact ingredients at the exact dose.
- 60–79: Single double-blind RCT + supporting ingredient literature at the studied dose.
- 40–59: Open-label trials + ingredient literature; no product-specific double-blind evidence.
- 20–39: Ingredient literature only; no product-specific trials or trials in predatory venues.
- 0–19: No credible evidence base or unverifiable claims.
