Why this scored 54/100
Cortitrol is Nu Skin's cortisol-modulation formula, positioned around 'enhanced feelings of well-being' with 60 capsules per bottle. Cortitrol formulations across the market typically combine phosphatidylserine (PS, from soy or sunflower lecithin — 300-600mg has Grade B evidence for blunting exercise-induced and mental-stress cortisol rise, Monteleone 1990, Starks 2008), ashwagandha (300-600mg standardized, Grade B for perceived stress and cortisol reduction, Chandrasekhar 2012), magnolia bark (Honokiol/Magnolol, Grade C-B for anxiolytic effect via GABA-A modulation), and sometimes epimedium or L-theanine. The 'Cortitrol' branding implies direct cortisol-lowering action — this is more supportable than most Nu Skin 'anti-aging' claims because PS and ashwagandha do have published cortisol-attenuation data. Whether the specific Cortitrol formulation delivers these at studied doses is the label question. Standard Nu Skin MLM caveats. Sits on Rejected/Standard boundary.

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.
