A high-quality supplement for energy and metabolism. The tablets are medium-sized, easy to swallow, and have no unpleasant aftertaste. I've noticed more energy, my morning sluggishness has gone away, and I feel lighter after meals. An excellent, effective product from a reliable brand; one bottle lasts two months. I'll be ordering again to maintain my energy.

I was satisfied

I took TMG from Source Naturals on a recommendation and was pleased. I'm taking it as a course—I've noticed more energy, a clearer head, and less fatigue at the end of the day. The tablets are medium-sized and easy to swallow, with no unpleasant taste. They don't irritate my stomach, and I haven't had any side effects. It's great for supporting my nervous system and overall well-being. It's a high-quality product from a trusted brand, and the effects are gentle yet consistent. I think I'll be ordering more.

Works well! TMG (trimethylglycine) to support cognitive function and heart health. TMG also helps maintain normal homocysteine levels, which is very important for the cardiovascular system. It also supports liver function, promoting detoxification and fat breakdown. can be a good tool for maintaining stomach and liver health. Excellent quality supplement, where all ingredients are carefully selected. The size of the capsules is normal, convenient to swallow. Good natural composition, suitable for all ages. Tastes good. Helped parents and husband normalize homocysteine. 60 tablets in a package is the optimal amount. Most effective in combination with B vitamins

I always read reviews and want to believe they're honest. So, I try to tell the truth. This is a good supplement, but it may not be right for everyone. Consult a nutritionist or naturopath. Your health comes first! I ordered this product based on recommendations and positive reviews. The ingredients are carefully selected and high-quality. The taste is great. The long-term benefits are enormous! The packaging is convenient, and the capsules are a standard size. Thank you for the fast delivery. I've trusted this store for years!

A little calcium + TMG

Verified Purchase

Quality ingredients are products of a trustworthy company. I know Source Naturals well because I have tried other companies' products. There were many effective products. I have tried TMG products from other companies as well, and this company's product is hard. It is not in powder form. This ingredient has many beneficial effects, such as improving the methylation process, improving fatty liver, and improving fatigue, and promoting protein synthesis. I sincerely hope for the health of our members. Tree Myobeopyeonhwagyeong Uparatabul Yeondeungbul Daetongjiseungbul

Trimethylglycine (Anhydrous Betaine) Dietary Supplement Suitable for Vegetarians. Trimethylglycine, also known as anhydrous betaine, is found in a variety of plant and animal sources and is used in the conversion of homocysteine to methionine. Maintaining normal homocysteine levels is essential for supporting the cardiovascular system. Trimethylglycine has been shown to help protect the liver and raise S-adenosylmethionine (SAMe) levels in animal studies. SAMe may help promote a balanced emotional state.

Firstly, the 240-tablet package is very convenient and allows me to take it for a long time without worrying about refilling. The tablets are small and easy to swallow, which is a big plus for me, as I don't like large capsules. As for the effects, I've noticed that TMG helps me better manage stress and improves my overall well-being. This supplement also maintains my energy levels and concentration, which is especially important during periods of increased work pressure. I feel more focused and productive. I also appreciate that the product is free of artificial additives and allergens, which is an important criterion for me when choosing supplements. I try to take care of my health and choose only high-quality products. Overall, I'm very pleased with Source Naturals TMG and recommend it to anyone looking for a way to support their health and improve their overall well-being. It's a truly beneficial product that has become a great addition to my diet!
