Why this scored 48/100
Maca (Lepidium meyenii) is a Peruvian cruciferous root with a moderate evidence base for female sexual function (Dording 2015 antidepressant-induced sexual dysfunction, small RCT), some evidence for perimenopausal symptoms (Meissner 2006), and mixed evidence for libido and fertility. The 'nursing' framing in the title is concerning — 'nursing' typically refers to breastfeeding/lactation, and maca is NOT recommended during breastfeeding (limited safety data, potential hormone-modulating effects). If 'nursing' here means 'nurturing/care' (poor translation), the ambiguity is a labeling failure. If it genuinely markets to breastfeeding women, it's a safety-inappropriate claim. Additionally, maca's active glucosinolate content varies enormously by species (red, yellow, black maca have different clinical uses per traditional use) and extraction method; this SKU does not disclose color/type or dose. Standard 48/100 near the Rejected threshold: real ingredient with real evidence for specific women's-health uses, but the 'nursing' framing ambiguity and no ingredient specifications keep it low.

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.
