TMG Crystals provides trimethylglycine, an important methyl donor (a.k.a., anhydrous betaine). Methyl donors, such as TMG and folic acid, are required for converting homocysteine (a toxic amino acid and a serious health risk) back into methionine and for the accurate synthesis of DNA and RNA, which is essential for the production of normal cells.

Suggested Use

Take 1 scoop per day or as directed by your qualified health care consultant.

Other Ingredients

Great price!
I'm happy with my TMG. I'm using it for depression and it has definitely improved my mood and mental clarity--the effects for me were immediate. It makes sleeping more difficult--so I take literally the smallest amount you can imagine--just a pinch. I tried SAM-e in the past and didn't like the enteric coating--seems like this has the same effect and I like it much better because it's about a tenth of the price, there's no enteric coating, and I can tailor my dose to my needs.

Instant side effects with only 1/3 scoop!
This gave me a pressure headache within minutes of ingestion. I show symptoms of homocystinuria which might simply be mimicked by candida's malabsorption syndrome, the resutls are the same since I can't digest/metabolize B vitamins! Anyway, extensive research on homocystinuria led me to purchasing this item. I woke up just past 5am, a bit later than I wanted and right after breakfast started experiencing CFIDS/herxheimer symptoms. Thinking this would alleviate the fatigue, I put 1/3rd of a scoop in an empty capsule. Bad idea! I became instantly confused, with an incipient headache and just this feeling of overall malaise. Thankfully I keep charcoal caps at hand: they mop up toxins, medicines and supplements OD alike. I took 2 and within minutes experienced relief from the TMG side effects in the sense of head pressure gone, brain fog and fatigue lifted. I did a quick google on the side effects: many people at forums report the exact same thing. What a bummer! I thought this was the missing link, I guess not! Also please note: 1) There is no info provided as to whether this is the toxic synthetic TMG (now I do wonder!) or whether it's derived from natural sources. 2) Whereas shampoo bottles give detailed step by step instructions on where to apply the shampoo and what to do with it once you have hand to head, this bottle leaves us absolutely in the dark! It doesn't say whether to take on empty stomach or after a meal; it doesn't even tell us whether to drop the powder in food, tongue or how. I have empty capsules, if you do not, I don't know how palatable this is, might be bitter or sweet, don't know! On the plus side, there is a really cute tiny scoop inside this bottle. I guess 1 star for cute mini scoop! :-|
