Nutrient Processing & Metabolism

How well you absorb, convert and use nutrients is shaped partly by your genes. Genetic tests can highlight tendencies; blood tests measure your actual levels.

Genes and nutrients

Many nutrients need to be transported, converted into active forms or stored. Genetic variants in the proteins that do this work can influence your tendencies. Some well-studied examples:

  • Vitamin D: genes such as CYP2R1 (which converts vitamin D in the liver) and GC (which makes vitamin D-binding protein) are associated with differences in blood vitamin D levels.
  • Folate and B12: see Methylation & Folate Metabolism.
  • Iron: HFE variants affect iron absorption. See Hereditary Hemochromatosis.
  • Caffeine: the CYP1A2 enzyme breaks down caffeine. Variants are associated with faster or slower caffeine metabolism.

Tendencies vs. levels

Your genes don't change, but your nutrient levels do, depending on diet, absorption, health conditions and medications. A genetic tendency toward lower vitamin D, for example, doesn't mean your vitamin D is low today.

To know your actual nutrient levels, you need a blood test. Genetic results can help you and your practitioner decide which levels may be worth checking or monitoring.
