Rhubestryn Menopause Symptom Relief - 30 Capsules

Six-dimension breakdown

Why this scored 48/100

Rhubestryn is a low-visibility SKU whose brand-provenance trail is thin — no clearly identifiable manufacturer disclosure, no published Supplement Facts panel at the title level, and no independent third-party lab documentation. The listing describes generic menopause-symptom-relief positioning (hot flashes, mood swings, sleep) without naming the actual botanical stack, dose per constituent, or standardization. The most likely active is a rhubarb-root extract (ERr 731, marketed elsewhere as Estrovera) given the 'Rhu-' prefix — that specific extract does have moderate RCT support for vasomotor-symptom reduction, but without the manufacturer confirming it is ERr 731 at the studied 4 mg/day dose, a reviewer cannot map this product to that evidence base. Menopause symptom-relief claims combined with undisclosed dosing and thin brand provenance are exactly the pattern the transparency and misleading-naming autofail rules exist to catch. Not autofailed outright only because the underlying category (rhubarb-root ERr 731) has legitimate evidence — but the specific SKU as sold cannot be verified as delivering that active. Would need full quantitative facts panel, explicit ingredient identity (is this ERr 731?), and third-party COA to move above Standard.

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.
