Betaine TMG Capsules give you betaine, also called trimethylglycine, as betaine citrate, the methyl donor found in beetroot, spinach and wholegrains. Each capsule provides 560mg of betaine citrate and you take one a day with food. One pot holds 90 capsules, which is a 90 day supply.
Betaine is glycine carrying three methyl groups, which it hands to other molecules in hundreds of reactions. It works on the pathway that recycles homocysteine, the same one folate and vitamin B12 work on, so people take it for methyl support without raising their folate or B12 intake. This is not the same product as betaine HCl, which is taken for stomach acid.
Betaine TMG Capsules are most useful for:
If you want the B vitamins for the same pathway in one capsule, Anti Homocysteine Support Capsules give B2, B6, folate, B12 and choline together.
Each capsule provides 560mg of betaine citrate. There is nothing else in it apart from the vegetable capsule shell. Trimethylglycine, TMG and betaine anhydrous are other names people search for. The body also makes betaine from choline. There is no authorised health claim at this amount, so Nutri Tailor describes it by what it contains.
Take one capsule a day with food. It goes with meals, unlike betaine HCl, which is taken before them.
The capsules are suitable for vegans and vegetarians. They are free from gluten, dairy and nuts.
The capsules are made in the UK in a GMP certified cleanroom facility accredited to ISO 9001 and ISO 14001. Every batch is traceable from raw material to finished product. Like every supplement Nutri Tailor stocks, they are practitioner grade and guaranteed additive free.
Is betaine TMG the same as betaine HCl?
No. They share a core molecule but do different jobs. Betaine citrate, the TMG here, is the methyl donor form taken with food. The hydrochloride is taken before meals as a source of stomach acid. They are not interchangeable, so check which one you were advised.
How much betaine should I take a day?
Take one capsule a day, which gives you 560mg of betaine citrate. A pot of 90 lasts 90 days.
Does betaine have an authorised health claim?
There is an authorised claim that betaine contributes to normal homocysteine metabolism, but it applies at 1.5g of betaine a day, which is more than one capsule gives. This page describes what the capsule contains rather than what it does.
Can I take it with other supplements?
Yes. It is most often taken alongside L-Methylfolate 5-MTHF Capsules and Vitamin B12 Methylcobalamin Drops, the two B vitamins that work on the same pathway.
What does a methyl donor do?
It hands a methyl group to another molecule so a reaction can go ahead. Betaine does this on the step that turns homocysteine back into methionine.
Does betaine have side effects?
Betaine is well tolerated at one capsule a day, because it is a compound found in everyday food. If you take prescribed tablets, are pregnant or breastfeeding, speak to your GP or pharmacist first.

Betaine, or trimethylglycine, is glycine carrying three methyl groups. It occurs in beetroot, spinach and wholegrains, and the body makes it from choline.
One capsule a day with food.
It hands a methyl group to other molecules. Betaine contributes to normal homocysteine metabolism, working alongside folate and B12.
No. TMG is the methyl-donor form taken with food. Betaine HCl is taken before meals as a source of stomach acid.
People following a methylation routine with methylfolate and methylcobalamin who want a methyl donor alongside them, and people whose practitioner has suggested TMG. It is not the product for stomach acid; that is Betaine HCl. There is no authorised health claim at this dose, so Nutri Tailor does not promise an outcome.
Same core molecule, different job. Betaine citrate (TMG) is the methyl-donor form taken with food. Betaine hydrochloride is taken before meals as a source of stomach acid. They are not interchangeable.
Tablets need binders, fillers and a coating to hold their shape. A capsule is a cellulose shell around the powder, so it carries no binders and breaks down quickly once swallowed.
