What to check on the label

  • Whether every ingredient has its own milligram line, or several are grouped in a 'blend' with one total.
  • How many capsules or scoops make a serving, and how many servings the container holds.
  • Whether the ingredients you care about appear at amounts you would accept on their own. The list below shows each figure.

Amounts are per label serving as recorded in the catalog and are not a recommendation. Testing status reflects what the brand lists. Nothing here is medical advice.

How we scored this product Show the full breakdown
Dose vs. studies (50%) Why 8.2 of 10. Primary ingredient is Beta-Glucan (evidence grade B). It delivers only 200 mg, 13% of the studied range low edge (1500 mg). Too low to expect the trial effect. Read the rule → 8.2
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. One day at the trial dose costs about $29.98. That is one of the pricier options in the catalog (307 of 313 by cost per effective day). Read the rule → 3.0
Formulation (10%) 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 Default. No absorption data on file.
Safety (5%) Why 5.0 of 10. Baseline 5.0. Third-party testing adds 2.0. Public lab certificate adds 1.5. NSF, USP or Informed Choice certification adds 1.5. Active safety signal subtracts 3.0. Read the rule → 5.0
Community sentiment (5%) Why 9.1 of 10. No external reviews found, so community sentiment defaults to neutral. Community never counts as clinical evidence. Read the rule → 9.1
Composite How this 6.6 is built. 0.50 × 8.2 + 0.20 × 5.0 + 0.10 × 3.0 + 0.10 × 5.0 + 0.05 × 5.0 + 0.05 × 9.1 = 6.6 out of 10. Safety caps applied after. 6.6

Value10%3.0
Formulation10%5.0
Safety5%5.0
Community5%9.1

Evidence 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. Safety 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.

Why this scored this way

This Aidan Products Stem-Kine scores 6.6, making it a mid-tier product with both strengths and weaknesses. It delivers 0mg of Vitamin D3, inside the studied range of 0–0mg 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 8.2 reflects good alignment with trial doses.
  • Community score of 9.1 with positive consumer feedback.
  • Vitamin D3 is dosed at the full research level with grade A evidence (strong human trial data).

What drags it down

  • Overall dose is only 13% 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.
  • At $29.98/day it's on the expensive side.

Why you'd choose it

  • You want Vitamin D3 from a Aidan Products product.
  • You want doses that align with published research.

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).
Question 1

Does the molecule work?

The science behind each active ingredient, independent of which brand sells it.

Beta-Glucan

Oat beta-glucan for cholesterol; yeast beta-glucan for immunity.

No landmark RCTs listed · US: Dietary supplement · EU: Food supplement, health claim (oat)
Vitamin D3

Cheap, safe, and correcting a deficiency you probably have.

Full ingredient breakdown

Every active in this formula, its declared dose per serving, the dose used in the primary human trial, how much of that trial dose this product delivers, and the evidence grade for the ingredient itself.

IngredientDose / servingResearch dose% of researchEvidence grade
Beta-Glucan200 mg3000 mg7%B
Vitamin D30.025 mg0.05 mg50%A

Percentages are dose per serving ÷ primary trial dose. Below 50% means the formula is unlikely to reproduce the trial outcome for that active. Grade A = multiple large human RCTs. Grade F = no human evidence. How grades work. Full glossary →

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.

Editorial 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.
