Why this scored 60/100
Neurogan Health Spermidine Drops deliver 20 mg of highly purified spermidine trihydrochloride per 0.5 ml serving from a 2 oz dropper — a synthetic, wheat-free source that allows precise dosing (an advantage over wheat-germ-derived spermidine, where per-lot content varies). 20 mg is the highest oral spermidine dose commercially available and sits above the ~1-6 mg range studied in the SmartAge and other cognitive/longevity RCTs (Wirth 2018, Schwarz 2018). The evidence base for oral spermidine is early-stage but interesting: observational data (Kiechl 2018) associates higher dietary spermidine with lower all-cause mortality, and small RCTs suggest modest memory-performance improvement in older adults with subjective cognitive complaints. Standard tier — legitimate delivery format, honest dosing, real brand, held back by thin clinical evidence and by the fact that dietary spermidine (wheat germ, aged cheese, mushrooms, natto) delivers meaningful amounts at zero cost.

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.
