Product description

TMG (Trimethylglycine) is known to facilitate methylation processes. Methylation is a normal biological process that is critical for DNA repair, liver detoxification mechanisms, lipid metabolism, and the production of SAMe. It is also an important step in the conversion of homocysteine, a damaging amino acid, into a more friendly amino acid, methionine. Supplementation with TMG has been shown in clinical and non-clinical studies to support healthy homocysteine levels already within normal range. Since 2000, the NOW brand has been supporting Canadians with a mission to provide products that empower people to lead healthier lives. 70% of the NOW products in Canada are made or packaged in Guelph, Ontario, employing hundreds of Canadians from coast to coast. NOW performs 31,000 quality tests every month to ensure you get the highest quality supplements at the best price possible. Our promise - what is on the label, is precisely what is in the bottle.

    Been using this for a few months to support methylation and liver health. I’ve experienced a subtle yet consistent improvement in my overall energy and mental clarity. The capsules are easy to swallow and there’s no odor or aftertaste. Great value and clean formulation.

    Reviewed in Canada on January 31, 2025
    Verified Purchase
    These seem to work but my second bottle now the pills split open in the bottle like they expand a little. They crack all around the flat sides and start to pop open. Makes me a little nervous. I leave the moisture thing in them and I only open the bottle once a day to take my pill but this is the second bottle that they do this. I think I will try another brand for my next one.

    5.0 out of 5 stars I was dubious, but they did seem to work! Ordered them again.
    Reviewed in Canada on April 8, 2025
    Verified Purchase
    I'm always extremely dubious of most supplements. After watching a couple of Youtube videos extolling the latest studies on TMG and it's potential for muscle building, I thought these were inexpensive enough to test. Two things:
    1) I absolutely feel like I gained muscle in the one month test, and
    2) I was shocked that there was considerably less muscle soreness after workouts. I do not recall this being touted in the videos I watched. This alone was enough reason to try it for another month.

    5.0 out of 5 stars Magique pour effets de médicaments contre tdah
    Reviewed in Canada on March 31, 2025
    Verified Purchase
    Je souffre de tda et syndrome de la tourette léger et avec ma médication (sans tmg) j'ai des sueurs et perte de circulation dans les extrémités, beaucoup de difficulté à dormir le soir car le médicament dure près de 14h. TMG enlève tout ces effets secondaires et m'aide énormément je recommande si vous avez de la difficulté à rester concentré ou à être vigilant. Peut être contingenté si mélanger à dautre médicaments donc vérifier sur chatgpt ou internet avant de prendre.

    Bought on the recommendation of a medical herbalist for cardiovascular health.Gave me a bad stomach after taking two tablets so I stopped taking them.My husband however carried on taking them for about a week before he had terrible pains in the stomach with nausea and sweating - it was very frightening.Be aware of the nasty side effects which affect some people.
