What three capsules a day do

Healthy homocysteine and liver support, in three capsules a day

Your body spends methyl groups all day, recycling homocysteine and helping your liver package fat for export. TMG carries three on every molecule, and every serve is 2,000mg of it.

How TMG works

Give a methyl. Recycle homocysteine.

  1. 1
    2,000mg of TMGPure betaine anhydrous in every three-capsule serve
  2. 2
    Hands over a methylYour liver passes one of the three to homocysteine
  3. 3
    Back into methionineThen SAMe, which feeds DNA methylation and liver fat export

Healthy homocysteine from the first day

In a six-week trial of 76 healthy adults, betaine lowered fasting homocysteine against placebo at every dose, and the spike after a methionine load was smaller from day one. It works through its own pathway, alongside folate and B12. Each serve is 2,000mg, between the trial's 1.5g and 3g doses.

Made for NMN and NR routines

Using NAD+ releases nicotinamide, and your body clears it with a methyl group. More NMN or NR means more methyl groups spent. TMG puts them back.

Three methyl groups on every molecule

Liver support

Betaine does most of its work in your liver. It helps liver cells hold their water balance and supplies the methyl groups used to package and export fat.

Craig, American Journal of Clinical Nutrition, 2004

Stronger in the gym

In strength-trained men, 2.5g a day for six weeks increased arm size and bench-press training volume and improved body composition, compared with placebo.

Why TMG goes with NMN and NR

NMN and NR top up NAD+. Every time your cells use NAD+, it leaves a nicotinamide behind, and clearing it costs a methyl group. TMG puts methyl groups back.

In a trial of single 100, 250 and 500mg NMN doses in healthy men, the methyl-tagged forms of nicotinamide in the blood rose with every dose. Irie et al., Endocrine Journal, 2020 →

Easy to add

Add it to the routine you already have

  1. Keep your NMN or NR as usual. Nothing about it changes.
  2. Add three TMG capsules with breakfast. That's the full 2,000mg serve.
  3. One bottle lasts 30 days. Or get all three in the NAD+ & Methylation Stack.
What to expect

Your first three months on TMG

Methyl support starts with the first serve and builds with daily use.

  1. Day 1

    Methyl support starts

    In the main trial, the homocysteine spike was already smaller on the first day.

  2. Weeks 1–2

    Make it a habit

    Three capsules with breakfast. In one trial, active men did more squat reps within a week.

  3. Week 6

    Up to 20% lower

    After six weeks, fasting homocysteine was 12% to 20% lower than placebo, by dose.

The research

Backed by human clinical trials

Betaine has been tested in randomised, placebo-controlled trials in people. Here is one clear result, then three more.

Randomised controlled trial · 2003 · 76 healthy adults · 6 weeks

After six weeks, fasting homocysteine was up to 20% lower than on placebo

Healthy adults took a placebo or 1.5g, 3g or 6g of betaine a day. Homocysteine came down at every dose, and the spike after a methionine load was smaller from the very first day. One serve of Eternal Elixir TMG is 2,000mg, between the trial's two lower doses.

Randomised controlled trial · 2003

Lower homocysteine where it started high

In adults with mildly raised homocysteine, 6g a day for six weeks lowered it by 1.8 µmol/L against placebo, and blunted the rise after a methionine load, where folic acid did not.

More squat reps in a week

In 24 active men, a week of betaine raised the number of squat reps to exhaustion against placebo, and more of their reps stayed near peak power through day 14.

How to take it

Three capsules, once a day

  1. Take 3 capsules daily, preferably with a meal, or as directed by your healthcare professional. That's the full 2,000mg serve.
  2. Make it part of breakfast. Plenty of people take TMG in the morning alongside their NMN or NR. Splitting the three capsules across two meals works too.
  3. Keep it daily. In the main trial, the effect on homocysteine grew from day one to week six. At 3 capsules a day, one bottle lasts 30 days.

Good to know

For adults only. Don't use if pregnant or breastfeeding. If you have a medical condition, including a kidney condition, or take prescription medicine, talk to your doctor first. Very high doses (6g a day) raised cholesterol slightly in trials, so check with your doctor if yours is high.

What's inside

One active ingredient. Nothing else.

TMG is trimethylglycine: the amino acid glycine carrying three methyl groups. It's also called betaine, after the sugar beet it was first found in. We use the pure anhydrous form, in a vegetable capsule with a little rice flour.

FAQ

Questions before you buy

What is TMG, and why is it also called betaine?

TMG stands for trimethylglycine: the amino acid glycine carrying three methyl groups. It was first isolated from sugar beet, which is where the name betaine comes from, and it occurs naturally in beetroot, spinach, wheat bran and quinoa. The supplement form is betaine anhydrous, which is the form in each capsule.

Why do people take TMG with NMN or NR?

When NAD+ is used, it releases nicotinamide, which the body clears by attaching a methyl group to it through the enzyme NNMT. Raising NAD+ with NMN or NR increases the demand on your methyl reserves. TMG replenishes those reserves and keeps homocysteine in check. Whether every NMN user strictly needs it is still debated in the research, but it is inexpensive insurance. Take it with your morning NMN.

What does TMG do for homocysteine?

TMG donates a methyl group directly to homocysteine through the liver enzyme BHMT, converting it back into methionine. In a six-week randomised trial of healthy adults, 1.5 g and 3 g of betaine a day lowered fasting homocysteine by 12% and 15% respectively, and blunted the homocysteine spike after a methionine-rich meal by up to 40%. Our 2,000 mg serve sits inside that range. Because it works through a different pathway from folate and B12, it complements rather than replaces them.

How much should I take, and when?

Three capsules a day with a meal, which gives 2,000 mg of betaine anhydrous. You can take all three at breakfast alongside NMN or NR. Splitting the serve across two meals is fine too. If you are targeting a specific homocysteine result, work with your doctor and retest after six to eight weeks.

Does TMG support liver health?

Yes. Betaine is concentrated in the liver, where it does two jobs. It acts as an osmolyte that helps liver cells manage water balance under stress, and it supplies the methyl groups the liver needs to package and export fat. That is why it is studied for liver health and healthy fat metabolism. For extra liver support, it pairs well with our TUDCA.

Is TMG the same as betaine HCl?

No. Betaine HCl is a hydrochloride salt sold as a digestive aid to increase stomach acid, and it is not the right form for methylation. Betaine anhydrous, the pure trimethylglycine in this product, is the form used in the homocysteine and performance trials.

Are there side effects, or people who should avoid TMG?

At 2 g a day TMG is generally well tolerated. Mild digestive upset can occur at higher doses. In trials using 6 g a day, some participants saw a modest rise in blood lipids, which was not seen at lower doses, so if you have high cholesterol, discuss it with your doctor. It is intended for adults. People with kidney conditions, a medical condition or on prescription medication should check with their healthcare professional first. Do not use if pregnant or breastfeeding.

How long does a bottle last, and is it vegan?

At 3 capsules a day, a bottle lasts 30 days. Two bottles last two months, three last three and five last five. Take more than three a day and it runs out sooner. Each bottle holds 90 vegetable capsules, and the one active ingredient is betaine anhydrous. The capsule is vegetable and the only other ingredient is rice flour, so it suits vegans and vegetarians. Two bottles save 10%, three save 15% and five save 20%.

How fast is shipping, and what if it isn't for me?
