Your body actually has two major pathways for recycling homocysteine back into methionine. One depends primarily on folate and vitamin B12. The other uses choline-derived betaine.

MTHFR is one of those topics that can send parents down a rabbit hole very quickly. A child has anxiety, allergies, ADHD symptoms, food sensitivities, a tongue-tie, a sacral dimple, or a “sugar bug” vein between the eyes, and suddenly the internet says: “It’s MTHFR.” While it may be MTHFR, the truth is far more nuanced and definitely less scary.

Choline is an essential nutrient that plays a vital role in brain function, liver health, and cellular metabolism. For people with the MTHFR gene mutation or methylation imbalances, understanding choline’s different forms, food sources, and health benefits becomes even more important.
