Nugenix T Boost - Free Testosterone Booster Supplement for Men, 90 Count

Six-dimension breakdown

Why this scored 42/100

Nugenix is a mainstream testosterone-booster brand (marketed by Adaptive Health, sold heavily via TV/late-night advertising and mass retail including GNC). The Nugenix line has historically used proprietary blends that hide per-ingredient milligrams behind a single 'Testosterone Complex' or similar grouped panel line item. The category — natural testosterone boosters marketed to middle-aged men — has weak evidence overall for measurable testosterone level increases in eugonadal men, with meta-analyses consistently showing modest or null effects for most of the common ingredients. Nugenix formulations typically feature Testofen (a fenugreek extract, one of the few natural test-boosters with mixed positive evidence for testosterone and libido), zinc, and vitamin B6/B12 — but with the Testofen dose obscured by the proprietary blend structure, users cannot verify whether they are ingesting the studied 600 mg/day dose. Distributed via 'Price Is Right Miami' (a Shopify reseller name) rather than direct from Nugenix, though the underlying brand is legitimate mid-market. Autofailed under proprietary_blend_hides_dose. Sold at Rejected 42 rather than lower because the parent brand and manufacturing are real, even if the label transparency fails Vyvata's 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.
