Dose divergence: Experts recommend different amounts (200–400milligrams elemental magnesium, 400milligrams, 300-400milligrams, 200milligrams, 400–600milligrams). Check the Stack & Timing tab for study-backed dosing ranges.

Claims are extracted using AI (Claude) from publicly available transcripts, each attributed to its source with an extraction-confidence rating (high / medium / low) so it can be verified, then compared against PubMed research. See how our data is made.

When magnesium is insufficient, the body prioritizes it for ATP production at the expense of DNA repair enzymes, potentially contributing to long-term aging and health consequences.

Insufficient evidence to assessHigh confidence

None of the 20 listed studies directly address the specific mechanistic claim that magnesium deficiency causes the body to prioritize ATP production over DNA repair enzymes, or that this trade-off con…
