Folate 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.
What this measures
How your DNA shapes folate intake needs.
Folate absorption, transport, recycling, and use depend on a network — SLC19A1 brings it into cells, MTR uses methylated folate to remethylate homocysteine, MTRR keeps MTR functional, and the whole cycle runs through MTHFR (covered separately as a Phase 1 exemplar). The collective network sets total folate demand.
Carriers of common SLC19A1, MTR, and MTRR reduced-activity variants are associated with elevated folate demand — the system uses folate less efficiently and requires higher intake to produce the same downstream methylation output. Combined with reduced-activity MTHFR variants, the demand compounds.
Methylfolate (5-MTHF) bypasses several of the conversion steps and is the form most carriers of the reduced-function network respond to best. Folate-rich whole foods (leafy greens, asparagus, lentils, beans) provide natural folate. Alcohol depletes folate. Heat destroys some of it — raw and lightly-cooked preparations preserve more.
Folate isn’t only a "prenatal" nutrient. It runs DNA synthesis, neurotransmitter production, and homocysteine clearance in every cell. Which combination of variants you carry decides whether default dietary intake covers the demand or whether targeted methylated supplementation is the missing input.
Folate Intake Needs is one specific finding in this system. Your Genomic Lifestyle Optimization Report shows where your variants place you on the micronutrients and strategic supplementation spectrum — and what you can do about it: it renders as a dark card with a color marker calibrated to your variants, opening with the gene mechanism and closing with a practical, mechanism-led recommendation.

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 insight →Choline 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 insight →Copper 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 insight →FUT2 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 insight →Folic 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.
Read insight →Iron Intake Needs
Iron absorption and loss rates differ dramatically between people. Knowing yours prevents both anemia (too little) and accidental iron overload (too much)—two problems with opposite solutions that feel confusingly similar.
