So my doctor (who has just written a book on Methylation) has gotten around to prescribing me some supplements. She said that mt two COMTs++ are difficult to address but I was reading somewhere that GABA, Lithium orotate and Magnesium citrate some people are using that to some affect. My question is, what brand of GABA is considered the most effective, and good brand for Lithium and Magnesium too? Here's what else she has me on: Ammonia Scavenger (capsule has Yucca root, L-Orthanine, L-Citruline, L-Lysine HCl, Alpha-Ketoglutatate, Golden Larch and Vitamin B6.) And I must admit I think its helping with my PEM somewhat. But at $40 for 90 caps I think its more expensive than it needs to be. Adeno B12 Lozenge 3000mcg p/day L-Argenine (1,500mg AM) / L-Lysine (3000mg PM) Emulsified Vit D Someone commented I might need Methyl B12 too according to my SNPs.....?
