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

A concentrated (10mg) cycloastragenol capsule targeting telomere/telomerase support, this is the astragalus-derived compound the brief flagged, positioned specifically for telomere biology rather than general immune-support astragalus use.

In plain language

Why this scored this way

This ProHealth Longevity Cycloastragenol - 10 mg, 30 capsules scores 5.2, making it among the lowest-scoring produkter we track. It contains 10.0mg of NAC, which is only 2% of the 600mg trial dose with grade B evidence (promising human data, not yet comprehensive). Transparency is a clear strength (score: 9.0), with third-party testing and a public analysintyg. At $69.94/day it's among the more expensive options in Antioxidant.

What drives the score up

  • Quality transparency of 9.0: tested by independent lab with a public analysintyg.

What drags it down

  • Dose-evidence score of 4.2 is below average for the site.
  • Overall dose is only 2% of the trial dose across ingredients.
  • NAC (10.0mg is 2% of the 600mg trial dose) is significantly under-dosed.
  • Limited consumer feedback (community score: 6.0).
  • At $69.94/day it's on the expensive side.

Why you'd choose it

  • You want NAC from a ProHealth Longevity product.
  • You prioritise tested by independent lab produkter with public lab certificates.

Why you might skip it

  • You need a full trial dose of nac (this product under-doses it).
  • You want a cheaper option (this is $69.94/day).
  • You want a product that hits the full trial dose (this is at 2%).
