Magnesium Intake Needs
One of 108 insights in your Genomic Lifestyle Optimization Report.
Over 300 enzymes depend on magnesium, yet requirements vary widely. Higher-need individuals often feel dramatic improvement in sleep, stress response, and muscle function from optimized intake. It's one of the highest-impact changes available.
How your DNA shapes magnesium intake needs.
TRPM6 codes for a magnesium channel in the gut that controls how much dietary magnesium gets absorbed. TRPM7 handles cellular magnesium uptake throughout the body. CASR (the calcium-sensing receptor) shapes how kidneys handle the magnesium-calcium balance. Together they set both how much magnesium enters the body and how well it stays inside cells.
Carriers of common TRPM6/TRPM7 reduced-activity variants are associated with lower magnesium absorption and higher dietary requirements, and may experience symptoms (muscle cramps, sleep disruption, anxiety, fatigue) at intakes that would be adequate for typical-function carriers. Serum magnesium misses most of this because only ~1% of body magnesium is in blood; the rest sits inside cells.
Magnesium glycinate and threonate cross cell membranes more efficiently than magnesium oxide (the cheap supplement form, which mostly stays in the gut). Stress, intense exercise, alcohol, and caffeine all raise magnesium losses. Dark chocolate, leafy greens, pumpkin seeds, and almonds are the densest food sources. PPIs and certain diuretics deplete magnesium.
Magnesium deficiency is one of the most under-recognized clinical pictures, partly because the standard blood test isn’t sensitive to it. Which TRPM variant pattern you carry decides whether default dietary intake covers the need or whether targeted supplementation is the highest-impact micronutrient move.
In your report, Magnesium Intake Needs is one dark card: a color marker set by your variants, the mechanism in plain language, and one practical next step.

Blood Pressure Sensitivity to Sodium Intake
About half of people see their blood pressure rise with salt; the other half are neutral. This decides whether low-sodium is medically mandatory or an unnecessary restriction that just makes food taste worse.
Read insightCholine Intake Needs
Choline demand varies 2–3× between people. Higher-need individuals see noticeable improvements in focus, fat metabolism, and liver function from eggs or supplementation, while others coast fine without thinking about it.
Read insightCopper Levels
Copper is a behind-the-scenes player, affecting iron absorption, collagen production, and antioxidant defense. The catch: both deficiency and excess cause problems, and they look surprisingly similar. Your regulation pattern tells you which direction to watch.
Read insightFUT2 Status
"Non-secretor" status changes how you absorb B12 and shapes your gut microbiome. This explains why some vegetarians stay healthy for decades while others crash within years: same diet, very different biology.
Read insightFolate Intake Needs
Folate requirements vary widely, especially during pregnancy, high stress, or rapid cell turnover. Knowing yours prevents the subtle deficiency that quietly affects mood, energy, and long-term health without obvious symptoms.
Read insightFolic Acid Conversion Efficiency
Common variants reduce the conversion of synthetic folic acid (in supplements and fortified foods) into active methylfolate. If you're affected, standard prenatals and "enriched" bread aren't doing what you think. Methylfolate does.
