Does TMG interact with B-Complex?

Both support methylation.

TMG (betaine) donates a methyl group to recycle homocysteine back into methionine, and the B-vitamins (especially folate, B6, and B12) run the parallel methylation route, so together they give the body two ways to keep homocysteine in check.

What to do

A reasonable combination for methylation and homocysteine support. A typical TMG dose is around 1 to 3 g daily alongside a B-complex. If you are using it for a raised homocysteine reading, recheck the level after a few months to confirm it is working.
