Description

TMG (trimethylglycine), also known as betaine anhydrous, is a naturally occurring methyl donor that helps convert homocysteine back into methionine through a process called remethylation. This process supports normal homocysteine metabolism and methylation pathways involved in liver function and cellular health. Each capsule provides 500 mg of pure TMG with no fillers or additives.

TMG supports a separate pathway from folate and vitamin B12, while vitamin B6 supports another route for processing homocysteine. This complementary activity is why TMG is often paired with a methylated multivitamin for broader homocysteine-metabolism support. Clinical studies using multi-gram daily doses of TMG have reported reductions in plasma homocysteine, although those studied amounts exceed the 500 mg provided in a single capsule.

Frequently Asked Questions

Is TMG the same as Betaine Anhydrous?

Yes. TMG (Trimethylglycine) and Betaine Anhydrous are the same compound. “Betaine Anhydrous” is the formal name used in research and on competitor labels; “TMG” is the more common consumer-facing name.

Is TMG the same as Betaine HCl?

TMG (Betaine Anhydrous) supports methylation and healthy homocysteine levels; Betaine HCl supports stomach acid and digestion. They are different compounds for different purposes, and DWS's TMG product is the methylation/homocysteine form.

Why does my TMG supplement smell like fish?

A natural fishy odor is a normal characteristic of genuine TMG (Trimethylglycine) — it’s a sign of authenticity, not spoilage, and does not affect potency or safety.

What is TMG (trimethylglycine) used for?

TMG, also known as betaine anhydrous, supports normal homocysteine metabolism by donating a methyl group that helps convert homocysteine back into methionine. This process supports the body’s methylation pathways, which are involved in liver function and cellular health.

How much TMG should I take per day?

Follow the suggested use on the product label. Each Double Wood capsule provides 500 mg of TMG. Clinical studies examining homocysteine have generally used multi-gram daily amounts, which are higher than the amount in one capsule. Do not increase your intake to match a research dose without consulting a qualified healthcare professional.

Does TMG help lower homocysteine?

Research suggests that TMG supplementation can help reduce plasma homocysteine by supporting its conversion back into methionine. In one controlled study, adults taking 3,000 mg daily for six weeks had fasting homocysteine levels that were 15% lower than the placebo group. Individual results may vary, and this research dose exceeds the 500 mg provided in one capsule.

What are the side effects of TMG?

TMG is generally well tolerated, but some people may experience nausea, digestive discomfort, diarrhea, or an unusual body odor, particularly at higher doses. Consult a healthcare professional before use if you are pregnant, nursing, taking medication, managing a medical condition, or considering an intake above the suggested serving.
