Let’s explore “intracellular testing”

Supports amino-acid metabolism, neurotransmitter production and hemoglobin synthesis.

Supports DNA synthesis and one-carbon metabolism, including the pathway that processes homocysteine.

Supports collagen formation, antioxidant activity and absorption of nonheme iron.

Helps calcium absorption and bone mineralization.

Supports proteins involved in blood clotting and bone metabolism.

A botanical used in traditional preparations; it is not a dietary nutrient.

A carotenoid found in foods and in the retina.

Supports enzymes, immune function, wound healing and taste.

NAT2 encodes N-acetyltransferase 2, which helps process certain drugs and other compounds. Combinations of variants can influence acetylation status; one SNP usually does not tell the entire story.

VDR encodes the vitamin D receptor, which helps regulate gene activity in response to active vitamin D. A receptor variant does not by itself mean receptors are absent or that the blood vitamin D level is low.

VKORC1 encodes vitamin K epoxide reductase, part of the vitamin K recycling system used in activating clotting proteins. It is not simply a vitamin K receptor.

How the Purser approach moves from a nutrient finding to priorities, a manageable plan and reassessment.
