Let’s explore “Vitamin B9 / folate deficiency”

Helps convert food into usable energy and supports nerve function.

Provides building blocks for NAD and NADP, which participate in cellular energy reactions.

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.

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

Makes an enzyme that helps produce a form of folate used in the processing of homocysteine. Common variants are different from rare variants that cause severe MTHFR deficiency.

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

Fasting and supplement abstention improve interpretability.

Recent supplementation can elevate; very high values may be clinically relevant.

Fasting, liver function, inflammation, and carrier proteins matter.

Interpret relative to lipids when appropriate; assay-specific.
