TMG supports methylation alongside NR.

Nicotinamide riboside (NR) raises NAD+ much like NMN, and clearing the excess can consume methyl groups, so the same logic applies: TMG (betaine) donates methyl groups to replenish what the NAD+ pathway uses, guarding against a possible methylation shortfall.

What to do

Pairing NR with around 1 g of TMG daily is a common, reasonable longevity choice, though the human evidence that the methyl drain matters is still thin. It is low-risk and well tolerated, and adequate folate and B12 support the same system.
