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

Oh gee, I had asthma so bad, did treatments, given medication, nothing helping. Then told of this WITH Pycnogenol. Since within 2 months, asthma no longer is any issue. I can't say will do the same for you, but darned worth a try. Not going to harm. Used close to 25 years now and this brand.

Thanks for your feedback!

Methylation support

Posted by iHerb Customer on December 15 2017 | Verified Purchase

We use this for family members who need methylation support (one side of the family). Our 9yo with Autism has no problem with these large tablets, but others might. They are a nice format tablet, but are large and solid - but TMG is difficult to dissolve in water so if swallowing is a problem you may need to research the capsule/tablet size carefully. We have found the TMG for us works much better than DMG, as the DMG doesn't seem to last nearly as long during the day, and sometimes gives headaches. But exact use depends on the individual genetics so your mileage may vary (we also supplement with methyl B12), and for us large amounts of TMG works well, without much in the way of side effects. I can't comment much on purity - but we haven't had much issue with these that we can identify over the last year, so I tend to trust this brand. No issues with Soy, gluten or dairy detected by our little detector. Price and value for money is really good, so we stock up on these, they ship without issue and don't seem to have any storage issues (they keep for 6 months in the cupboard unopened without issue). Once out of the bottle they absorb water quickly from the air, and become unusable after 6-12 hours in the air, so storing them with oil or other tablets doesn't work - this is the only down side to these tablets I have found. If you want to package them to takeaway in a pill box I would probably recommend a capsule instead. But overall we find this product to be good value.

Thanks for your feedback!

I have mtfr and many good sources recommend this supplement. I've only been taking it for a month or so, too soon to tell. 4 stars for all the good recommendations - any my anticipation that it helps.
