Magnesium
50–90% of US adults are deficient in magnesium; important for multiple essential body functions. Ensure adequate intake via multivitamin every 2–3 days; obtain from nuts, legumes, and whole grains.
Why It Matters for Longevity
50–90% of US adults are deficient in magnesium; important for multiple essential body functions. Ensure adequate intake via multivitamin every 2–3 days; obtain from nuts, legumes, and whole grains. Cofactor for over 300 enzymatic reactions; essential for energy metabolism (ATP synthesis), DNA repair, muscle and nerve function, protein synthesis, and regulation of blood glucose and blood pressure.. Higher dietary magnesium intake is associated with reduced all-cause mortality, cardiovascular disease, and type 2 diabetes risk; each 100 mg/day increase in magnesium associated with a 22% lower risk of cardiovascular death in meta-analysis. (PMID 29093983) (PubMed) Magnesium is a required cofactor for telomerase activity and DNA double-strand break repair; chronic magnesium insufficiency accelerates genomic instability and cellular aging in animal models. (PMID 27933574) (PubMed)

Synergies
- Calcium (synergy): Magnesium is required for proper calcium metabolism, bone mineralization, and vascular calcium regulation; both must be adequate for bone longevity - Kidney Beans (complement): Kidney beans are a plant-based magnesium source; combined with other legumes and whole grains they can meet 50–60% of daily magnesium needs - Linseed Oil (synergy): Magnesium and omega-3 fatty acids (ALA from linseed oil) act synergistically to reduce cardiovascular inflammation and arrhythmia risk

The Science
- PubMed: Higher dietary magnesium intake is associated with reduced all-cause mortality, cardiovascular disease, and type 2 diabetes risk; each 100 mg/day increase in magnesium associated with a 22% lower risk of cardiovascular death in meta-analysis. (PMID 29093983) - PubMed: Magnesium is a required cofactor for telomerase activity and DNA double-strand break repair; chronic magnesium insufficiency accelerates genomic instability and cellular aging in animal models. (PMID 27933574) - PubMed: Magnesium supplementation reduces inflammatory markers (CRP, IL-6) and improves insulin sensitivity in people with type 2 diabetes and metabolic syndrome; meta-analysis of 32 trials. (PMID 31136047) - Examine.com: Magnesium glycinate and magnesium citrate have the highest bioavailability (70–80%) compared to magnesium oxide (~4%); food sources (nuts, legumes, leafy greens, whole grains) provide well-absorbed organic magnesium bound to amino acids and phytates. - Book claim (high confidence): 50–90% of US adults are deficient in magnesium; important for multiple essential body functions. Ensure adequate intake
Key Nutrients
| Nutrient | Per 100g | Notes |
|---|---|---|
| Magnesium (elemental) | RDA: 310–420 mg/day (adults) | Absorption 30–40% from food; magnesium glycinate and citrate best supplemental forms; magnesium oxide poorly absorbed |
| Magnesium in nuts (almonds) | 268 mg per 100 g | Well-absorbed from whole foods despite phytate binding |
| Magnesium in legumes (black beans) | 70 mg per 100 g (cooked) | Soaking and cooking reduces phytate, improving bioavailability |
