Bevisning gates dose: the evidence grade sets the ceiling, and the dose decides how much of that ceiling the product reaches. Value = inverse of price-per-trial-dose-day. Community = mean sentiment of external reviews. Säkerhet caps applied after weighting.

This score is our editorial judgment, not a scientific standard. We combine published evidence, dose, price, transparency, and consumer signals into one composite: this is our method, not a peer-reviewed clinical rating. A higher score means a product does better on the factors we weight, not that it is medically proven to work.

Redaktionellt notes

The flagship, most complex Cognitex SKU, combines sage, blueberry, ashwagandha, phosphatidylserine, pregnenolone, UMP, and vinpocetine in one tablet; broad-spectrum nootropic approach with individually-studied components, though the pregnenolone inclusion (a hormone precursor) is worth flagging for anyone sensitive to hormonal supplements or in jurisdictions where it's restricted.

In plain language

Why this scored this way

This Life Extension Cognitex Elite Pregnenolone scores 5.0, making it among the lowest-scoring produkter we track. It contains 125.0mg of Ashwagandha, which is only 21% of the 600mg trial dose with grade B evidence (promising human data, not yet comprehensive). At $6.39/day it's among the more expensive options in Cognition.

What drives the score up

  • Tested by independent lab (transparency 8.0).

What drags it down

  • Dose-evidence score of 4.2 is below average for the site.
  • Overall dose is only 21% of the trial dose across ingredients.
  • Ashwagandha (125.0mg is 21% of the 600mg trial dose) is significantly under-dosed.
  • No public analysintyg available for independent verification.
  • Limited consumer feedback (community score: 6.0).

Why you'd choose it

  • You want Ashwagandha from a Life Extension product.
  • You want a tested by independent lab product.

Why you might skip it

  • You want a product with a publicly available CoA.
  • You need a full trial dose of ashwagandha (this product under-doses it).
  • You want a cheaper option (this is $6.39/day).
