What to check on the label

  • The unit on the label (µg, mg or IU) before comparing with the figures here.
  • For K2, which form is named (MK-4 or MK-7). The catalog stores the total.
  • Liquid drops: how many drops the label calls a serving, since the container count depends on it.

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.

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 DoNotAge Pure Vitamin D3, K2 & Magnesium scores 8.2, making it a strong scorer. It delivers 250mg of Magnesium, inside the studied range of 200–500mg with grade A evidence (strong human trial data). The quality transparency (5.0) is limited by the lack of third-party testing. At $0.08/day it's priced well for what you get.

What drives the score up

  • Dose-evidence score of 10.0 reflects good alignment with trial doses.
  • Value score of 10.0 at $0.08/day.
  • Community score of 8.6 with positive consumer feedback.
  • Magnesium is dosed at the full research level with grade A evidence (strong human trial data).

What drags it down

  • No third-party testing, which caps the quality transparency.
  • Quality transparency of 5.0 is below the site average.

Why you'd choose it

  • You want good value at $0.08/day.
  • You want Magnesium from a DoNotAge 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 want stronger transparency (this scores 5.0).

Important to know
MagnesiumMagnesium oxide has ~4% absorption and mostly acts as a laxative. Always check the salt form, not just 'magnesium'.

Editorial notes

High-dose D3 (5,000 IU) + K2 MK-7 + magnesium threonate 3-in-1 capsule; a popular convenience stack among reviewers, but not listed as tested by independent lab unlike most of the rest of the range.
