How we scored this product Show the full breakdown
Dose vs. studies (55%) Why 6.2 of 10. Primär ingredient is Beta-Glucan (evidence grade B). It delivers only 7% of the trialled dose. Too low to expect the trial effect. Read the rule → 6.2
Transparency (20%) Why 5.0 of 10. Earned points for all doses disclosed. Lost points for no public certificate of analysis and no independent third-party testing. Read the rule → 5.0
Value (10%) Why 3.0 of 10. Pris per effective day could not be calculated, so value defaults to the middle of the catalog. Read the rule → 3.0
Community sentiment (10%) Why 6.0 of 10. No external reviews found, so community sentiment defaults to neutral. Community never counts as clinical evidence. Read the rule → 6.0
Formulation (5%) Why 5.0 of 10. No published absorption advantage or disadvantage on file. The default of 5 is not a criticism. Read the rule → 5.0

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.

Research behind this product

The studies that established the trial dose and evidence grade for each active ingredient in this product. Click through to read the original paper.

Vitamin D3VITAL Trial 2018
Important to know
Beta-GlucanMatch source to goal.
Vitamin D3Taking without fat = poor absorption. High-dose D3 without K2 can drive calcium into arteries. D2 form (ergocalciferol) is inferior for raising blood levels.
Vitamin D3High doses (>4000 IU/day) may cause hypercalcemia. Do not exceed upper intake limits without medical supervision.

Redaktionellt notes

Stem cell mobilization formula built on a patented fermented astragalus root/goji berry/green tea extract (Lactobacillus fermentum blend) plus beta-1,3-glucan, ellagic acid and vitamin D3; clinically studied to increase circulating stem cell counts.

In plain language

Why this scored this way

This Aidan Produkter Stem-Kine scores 5.5, making it below the site average. It delivers 0.025mg of Vitamin D3 (50% of the 0.05mg trial dose) with grade A evidence (strong human trial data). The quality transparency (5.0) is limited by the lack of third-party testing. At $29.98/day it's among the more expensive options in Longevity stack.

What drives the score up

  • Dose-evidence score of 6.2 shows decent alignment with trial doses.
  • Vitamin D3 has grade A evidence and is dosed at 50% of the trial dose.

What drags it down

  • Overall dose is only 7% of the trial dose across ingredients.
  • Beta-Glucan (200mg is 7% of the 3000mg trial dose) is significantly under-dosed.
  • No third-party testing, which caps the quality transparency.
  • Quality transparency of 5.0 is below the site average.
  • Limited consumer feedback (community score: 6.0).

Why you'd choose it

  • You want Vitamin D3 from a Aidan Produkter product.

Why you might skip it

  • You want third-party verified purity.
  • You want a product with a publicly available CoA.
  • You need a full trial dose of beta-glucan (this product under-doses it).
