====Drug and Supplement Interactions====
===Drug and Supplement Interactions===
*'''Anticholinergic Drugs''': TMG might interact with anticholinergic medications, which reduce the effects of acetylcholine, as TMG increases levels of choline, a precursor to acetylcholine.

*'''Choline and Folate Supplements''': Concurrent use of TMG with other supplements that affect methionine metabolism, such as choline and folate, should be approached with caution, as they might synergistically increase levels of methionine, which could be detrimental.
