Quick Answer
**Bulk Nutrients TMG Capsules** is our top pick for the best TMG supplement in Australia because it combines Australian manufacturing, lab testing and a low $0.81 per 2,000 mg serve in a capsule format. For anyone taking TMG alongside an NAD+ precursor, **Eternal Elixir TMG 2000mg** is the best choice — it is the only capsule here that delivers a full 2,000 mg in one labelled serve.
Based on live Australian pricing normalised to cost per 2,000 mg serve across 6 products available to Australian buyers, checked 12 September 2026

**The short version: every product in this category sells you betaine anhydrous, and the powders are three to twelve times cheaper per gram than the capsules. What you are actually choosing between is convenience, label honesty and whether the serve on the tub matches the dose used in the research.**

That last point is where most buying guides in this category — and Google's own AI Overview for this query — quietly mislead. The AI Overview currently names Bulk Nutrients as "best value" at "120 servings for $29.00". True, but a serving on that label is a single 600 mg capsule.

The betaine trials that made this ingredient interesting used 1.5 g to 6 g a day. At 2,000 mg you are getting roughly 36 serves from that bottle, not 120. Once every product is re-priced against the same 2,000 mg unit, the ranking changes shape completely.

**Key numbers:**

- Cheapest per 2,000 mg serve in Australia: **$0.12** (imported bulk powder)

- Most expensive per 2,000 mg serve: **$1.50** (Eternal Elixir capsules)

- Spread between cheapest and dearest: **12.5×**

- Fasting homocysteine reduction at 1.5 g, 3 g and 6 g of betaine daily for six weeks: **12%, 15% and 20%** versus placebo (Olthof et al., *The Journal of Nutrition*, 2003, [PMID 14652361](https://pubmed.ncbi.nlm.nih.gov/14652361/))

- Number of TMG products in this comparison that publish a pack size on the product page: **6 of 6**

Eternal Elixir sells a TMG supplement, so read the ranking below with that in mind. We have not put ourselves first. On raw cost per dose we are the most expensive product on this page and we say so in our own entry. We have applied the criteria in the [How we picked the best TMG supplement in each category](#how-we-evaluated) section and let them fall where they fall.

## Best TMG Supplements in Australia 2026: The Comparison Table

All prices are AUD and were checked on 12 September 2026 from each brand's own Australian listing. The critical column is **cost per 2,000 mg serve** — not cost per capsule, not cost per "serving" as the label defines it, because label serves range from 600 mg to 2,000 mg across these six products and comparing them directly is meaningless.

Read the last row carefully. The imported bulk powder is **the cheapest TMG in Australia by a wide margin** — 6.75× cheaper per dose than Bulk Nutrients and 12.5× cheaper than our own capsules. It finishes sixth here because Australian availability, local support and verifiable batch documentation carry 65% of the weighting combined, not because the price is bad. If price is the only thing you care about, buy that one. We would rather say so than pretend otherwise.

## Why the Label Serve Matters More Than the Price Tag

TMG — trimethylglycine, sold interchangeably as betaine anhydrous — is a methyl donor. It carries three methyl groups and hands one to homocysteine, converting it back into methionine. That single reaction is the reason people take it, and it is dose-dependent.

The cleanest evidence comes from a double-blind, placebo-controlled trial of four groups of 19 healthy adults published in *The Journal of Nutrition*. Over six weeks, daily betaine at 1.5 g, 3 g and 6 g lowered fasting plasma homocysteine by 12%, 15% and 20% respectively compared with placebo, and blunted the post-methionine-load homocysteine rise by 23% to 40% ([Olthof et al., 2003, PMID 14652361](https://pubmed.ncbi.nlm.nih.gov/14652361/)). A later meta-analysis of randomised trials in healthy adults, published in the *Journal of Chiropractic Medicine*, reached the same directional conclusion — betaine supplementation decreases plasma homocysteine in healthy adults ([McRae, 2013, PMID 23997720](https://pubmed.ncbi.nlm.nih.gov/23997720/)).

Now apply that to the shelf. A 600 mg capsule is well under the lowest dose in that trial. A single 1 g scoop is under it too. To land inside the 1.5–6 g research range you need two to ten capsules of the 600 mg product, or one and a half to six scoops of the 1 g powders. None of that is a problem — it just means the "servings per pack" number on the front of the tub is not the number you should be dividing the price by.

This is the one adjustment that reorders the entire Australian TMG market, and no other comparison of these products makes it.

## TMG and NMN: How Much Methyl Load Do You Actually Need?

Most Australians searching for TMG are not searching for it on its own. They arrive via NAD+ — they have started NMN or nicotinamide riboside, read that raising NAD+ consumes methyl groups, and gone looking for the companion. The logic is real: as NAD+ is used, nicotinamide is released and cleared by the enzyme NNMT, which spends a methyl group each time.

What is *not* settled is how much TMG that actually warrants. There is no human trial establishing an NMN-to-TMG ratio, and anyone quoting you one is inventing it. What we can say honestly is this:

- The doses with human homocysteine data behind them are 1.5 g to 6 g of betaine daily. That is the range worth targeting.

- A 2,000 mg serve sits comfortably inside it, which is why it is the most common capsule serve.

- Nothing in the literature suggests you need to scale TMG to your NMN dose. Take a dose that has been studied, or don't take it.

- If your homocysteine is already in range and you are not supplementing NAD+ precursors, the case for TMG is thinner than the marketing suggests.

If you are still deciding between precursors before you worry about methyl support, our comparison of [NMN versus NR for Australian buyers](https://eternalelixir.com.au/nmn-vs-nr-nad-precursor-comparison-australia/) covers that decision, and the [Australian NMN buying guide](https://eternalelixir.com.au/best-nmn-supplements-australia/) is the cornerstone reference for the whole category. For the mechanism itself, our standalone explainer on [TMG benefits, methylation and liver support](https://eternalelixir.com.au/tmg-supplement-benefits/) goes deeper than a listicle reasonably can.

## #1. Bulk Nutrients TMG Capsules — Best Overall

**Key specs:** 120 vegetable capsules · 600 mg betaine anhydrous per capsule · label serve 1–2 capsules · $29.00 · $0.81 per 2,000 mg serve · manufactured in Tasmania.

[**Bulk Nutrients**](https://www.bulknutrients.com.au/products/tmg-capsules) takes the top slot on a straightforward reading of the criteria. It is the only capsule product on this page manufactured in Australia, it is the cheapest capsule per dose by a factor of nearly two, and Bulk's public lab-testing programme and volume of verified reviews give it the strongest reputation score of any brand here. The nutrition panel is fully disclosed: 600 mg of trimethylglycine per capsule, 83,102 mg per 100 g, no proprietary blend.

**Pros:**

- Cheapest capsule format per 2,000 mg serve at $0.81

- Australian-made, with a published lab-testing programme

- Multibuy pricing drops to $27.00 per bottle at four units

- Flat $9 shipping Australia-wide, Express Post under 3.5 kg

- Vegan, gluten-free ingredients, no allergens declared

**Cons:**

- The 600 mg capsule means a research-range dose is 3–4 capsules, not the 1–2 on the label

- Positioned as a sports supplementary food, so the framing skews athletic rather than longevity

- Not suitable for under-15s or during pregnancy per the label

**Best for:** anyone who wants capsules, wants them made in Australia, and is happy to take three or four at a time.

## #2. Eternal Elixir TMG 2000mg — Best for NAD+ Stackers

**Key specs:** 90 vegetable capsules · 2,000 mg betaine anhydrous per three-capsule serve · 30-day supply · $44.99 · $1.50 per 2,000 mg serve · dispatched from Sydney.

[**Eternal Elixir TMG 2000mg**](https://eternalelixir.com.au/product/tmg-capsules/) is the most expensive product in this comparison per dose, and there is no way to dress that up. What it buys you is a serve that already matches the studied range without arithmetic: three capsules, 2,000 mg, done. Across the rest of this table you are either counting out four 600 mg capsules or levelling scoops.

The second reason it ranks here is stacking. TMG is rarely bought alone, and Eternal Elixir carries the NAD+ precursors it is usually paired with — [NMN 500mg](https://eternalelixir.com.au/product/nmn-capsules/) and [nicotinamide riboside](https://eternalelixir.com.au/product/nicotinimide-riboside-capsules/) — plus TUDCA for liver support, from a single Australian dispatch point. Every batch is third-party lab tested for identity, potency, heavy metals and microbial contaminants, with a certificate of analysis available on request. Ingredients are betaine anhydrous, vegetable capsule and rice flour: no fillers, colours or preservatives, suitable for vegans.

**Pros:**

- Full 2,000 mg in a single three-capsule serve — no counting or measuring

- 90 capsules per bottle, a clean 30-day supply at the label dose

- Third-party tested with a COA available on request

- Ships from Sydney; free shipping over $100

- Sits in a range built for NAD+ stacking rather than sports nutrition

**Cons:**

- $1.50 per serve is the highest in this comparison — 12.5× the imported powder

- Capsules are inherently poor value against bulk betaine powder

- Three capsules is more swallowing than a one-capsule product

**Best for:** people already taking NMN or NR who want the methyl-donor companion at a studied dose, from one Australian supplier, without doing the maths.

## #3. myBrainCo TMG Powder 100g — Best Small-Format Powder

**Key specs:** 100 g pure trimethylglycine powder · 1 g scoop · 100 label servings · $29.95 · $0.60 per 2,000 mg serve · free AU shipping over $99.

**myBrainCo** is the sensible entry point for anyone who wants powder without committing to half a kilo of it. The product is unflavoured micronised betaine anhydrous, lab-tested per batch, with no sweeteners or flow agents. At $0.60 per 2,000 mg it is the cheapest domestically-supported option on this page, and a 100 g tub is small enough to test your own tolerance for betaine before you buy in bulk.

The trade-off is the one every powder carries: TMG tastes faintly sweet but slightly odd in water, and you are measuring by scoop rather than swallowing a fixed dose. Reviewers on the product page consistently describe it dissolving cleanly, and several mention buying it specifically to run alongside NMN.

**Pros:**

- $0.60 per 2,000 mg serve — cheapest AU-supported product here

- Small 100 g format is low-risk for a first purchase

- Lab-tested per batch, no additives, vegan friendly

- 45-day money-back guarantee on first purchase

- Subscribe option drops the price a further 15%

**Cons:**

- 100 g is only 50 serves at 2,000 mg — roughly seven weeks

- Scoop measuring is less precise than a capsule

- Narrower longevity range to stack with than a dedicated longevity brand

**Best for:** first-time TMG buyers who want powder economics without a bulk commitment.

**Skip the comparison — buy direct.** Eternal Elixir's [TMG 2000mg](https://eternalelixir.com.au/product/tmg-capsules/) ships from Australia in 90-capsule bottles. [Browse the range →](https://eternalelixir.com.au/shop/)

## #4. Switch Nutrition Trimethylglycine — Best for the Switch Ecosystem

**Key specs:** unflavoured powder · 1 g scoop · directions 1–3 serves daily · $44.95 from Switch Nutrition direct · 150 serves of 1 g (150 g tub) per the nutrition panel · $0.60 per 2,000 mg serve.

**Switch Nutrition** holds the second organic position on this search in Australia and is cited by Google's AI Overview as the "best pure powder for longevity stacks", so it is the product most Australians will encounter first. The formulation is what it should be: 100% pure trimethylglycine, vegan, no additives, with clear directions of one to three 1 g serves daily.

Where it loses ground is cost per gram, not quality. The [Switch Nutrition product page](https://switchnutrition.com.au/products/tmg) lists 150 serves of 1 g, so the tub is 150 g and $44.95 works out at $0.60 per 2,000 mg serve — line-ball with the myBrainCo powder at #3, and beaten by Switch stock sold through its own retail channel at #5. The pack size sits inside the nutrition panel rather than the headline description, which makes it easy to miss, but it is published.

**Pros:**

- 100% pure trimethylglycine, vegan, no fillers or sweeteners

- Clear 1–3 serve daily directions that reach the studied range

- Widely stocked across Australian retailers, so easy to find

- Strong brand recognition in the Australian sports nutrition channel

**Cons:**

- Pack size is buried in the nutrition panel instead of the headline description

- $44.95 direct is beaten by its own retail channel (see #5)

- Only one customer review on the direct listing at time of writing

**Best for:** buyers already stacking Switch products who want a large 150 g tub and channel familiarity.

## #5. Switch TMG via Australian Sports Nutrition — Best Price on the Same Tub

**Key specs:** identical Switch Nutrition product · 1 g scoop · $39.95 · $5.00 below the brand's own direct price.

This is not a different formulation. It is the same **Switch Nutrition** trimethylglycine listed by an Australian retailer at $39.95 instead of $44.95. It earns its own row purely to make the point that on commodity ingredients, the brand's direct price is frequently not the best Australian price, and TMG is about as commodity as supplements get — every product on this page is the same molecule.

Same 150 g tub, same 1 g scoop, so $39.95 works out at $0.53 per 2,000 mg serve — the cheapest verified powder on this page outside the imported Amazon listing. Elite Supps carries the same product as a third stockist, which is worth checking if neither of these is in stock.

**Pros:**

- $5.00 cheaper than buying the identical product from the brand

- Established Australian retailer with local dispatch

- Same pure trimethylglycine formulation as #4

**Cons:**

- Retailer listing does not restate the pack size, so you cross-check the brand page

- No brand-direct support or subscription pricing

- Stock availability fluctuates on a low-turnover ingredient

**Best for:** anyone who has already decided on Switch TMG and simply wants to pay less for it.

## #6. Best Naturals Betaine Anhydrous via Amazon AU — Best Raw Price

**Key specs:** 454 g powder · 2,000 mg per serving · 227 servings per container · $27.99 · $0.12 per 2,000 mg serve · third-party lab tested, non-GMO, gluten free.

On price alone this wins the category and it is not close. **Best Naturals** betaine anhydrous works out at roughly twelve cents per 2,000 mg serve — 6.75× cheaper than the best Australian capsule and 12.5× cheaper than ours. A 454 g tub at 2,000 mg a day lasts over seven months. If your only criterion is cost per gram of betaine, stop reading and buy this.

It finishes last on our weighting for reasons that have nothing to do with the powder itself. It is an imported product bought through a marketplace: dispatch timelines and stock are outside any Australian brand's control, there is no local customer support, returns run through the marketplace rather than a supplier you can call, and batch documentation is not available on request the way it is from a domestic brand. Those factors carry 65% of our weighting between them. They may carry far less of yours.

**Pros:**

- $0.12 per 2,000 mg serve — cheapest by a factor of five over anything else here

- 227 servings per container at a full 2,000 mg

- Third-party lab tested for purity, non-GMO and gluten free

- Label serve already matches the research-range dose

**Cons:**

- Imported via marketplace — no Australian dispatch guarantee or local support

- 454 g is a long commitment for an ingredient you may not tolerate

- Batch COAs not obtainable on request from an Australian supplier

- Marketplace listings for commodity powders change hands and formulations without notice

**Best for:** experienced users who already know betaine agrees with them and want the lowest possible cost per gram.

## How We Picked the Best TMG Supplement in Each Category

Six products, one scoring model, applied before we knew where our own product would land. The weightings:

- **Quality and purity (30%)** — is it pure betaine anhydrous with no proprietary blend, is the panel fully disclosed, and is batch testing documented rather than asserted?

- **Australian availability and shipping (20%)** — is it dispatched domestically, with a real local support path and predictable delivery?

- **Price per dose in AUD (20%)** — cost per 2,000 mg serve, normalised across capsules and powder, computed from the published pack size.

- **Product range for stacking (15%)** — can you buy the NAD+ precursors and liver support TMG is usually taken with from the same supplier in one shipment?

- **Customer reviews and reputation (15%)** — verified review volume and how long the brand has operated in the Australian market.

Two notes on honesty. First, we compared these products from published specifications, live pricing and label data — we did not test competitor products in a laboratory and we are not going to claim we did. "Third-party tested" on this page refers only to Eternal Elixir's own certificates of analysis. 

Second, the weighting above is why the cheapest product finishes sixth and why we finish second rather than first. Change the weighting to price-only and the imported powder wins outright. That is a legitimate way to shop, and we have given you the numbers to do it.

## Capsules or Powder? The Only Question That Actually Changes Your Cost

Across this table, capsules cost between $0.81 and $1.50 per 2,000 mg serve. Powders cost between $0.12 and $0.60. That is the whole decision, and it is worth roughly $250 to $500 a year at a daily dose.

What capsules buy you is adherence. Betaine powder is faintly sweet with a saline edge that some people find unpleasant in plain water, and a daily scoop-and-stir is a step more friction than swallowing three capsules with breakfast. A supplement you stop taking in week three has a cost per dose of infinity. If you already know you are a powder person, buy powder. If you have abandoned tubs before, pay the capsule premium and accept it.

The one thing not worth paying for is a "premium" TMG. Betaine anhydrous is a well-characterised commodity chemical with no meaningful bioavailability variation between forms — unlike, say, magnesium, where the salt genuinely changes where it goes, which is why our [magnesium L-threonate comparison](https://eternalelixir.com.au/best-magnesium-l-threonate-australia/) reads so differently to this one. With TMG, verify purity and buy on format and price.

## Where to Buy the Best TMG Supplement in Australia

This ingredient is not stocked by Chemist Warehouse, Priceline or the major grocery chains — it sits outside the mainstream pharmacy vitamin range, so the Australian supply is entirely online. Your realistic options are the sports nutrition channel (Bulk Nutrients, Switch and its stockists), the longevity specialists (Eternal Elixir, myBrainCo), or a marketplace import.

Delivery expectations are worth setting before you order. Domestic dispatch from Sydney, Melbourne or Hobart typically lands in two to five business days depending on state. Marketplace imports vary widely and are the one category where you should check the dispatch estimate before you commit, particularly outside the east coast. Free-shipping thresholds cluster around $99–$100, which is worth knowing if you are buying TMG alongside something else — pairing it with an [NAD+ supplement](https://eternalelixir.com.au/best-nad-supplements-australia/) or a [liver support product](https://eternalelixir.com.au/best-liver-support-supplements-australia/) usually clears it.

## Frequently Asked Questions

### Which brand of TMG is the best in Australia?

On our weighting, Bulk Nutrients TMG Capsules ranks first for the combination of Australian manufacturing, documented lab testing and $0.81 per 2,000 mg serve. Eternal Elixir TMG 2000mg ranks second and is the better pick specifically for people pairing TMG with NMN or NR, because three capsules deliver a full research-range dose in a single serve. If cost per gram is your only criterion, an imported bulk betaine powder beats every Australian option by a factor of five or more.

### Where can I find TMG supplements in Australia?

Online only. TMG is not carried by Chemist Warehouse, Priceline or supermarket vitamin ranges. Australian sources are direct-to-consumer brands — Bulk Nutrients, Switch Nutrition and its retail stockists, Eternal Elixir and myBrainCo — plus marketplace imports through Amazon Australia and iHerb. All six products in this comparison ship to Australian addresses.

### Does a TMG supplement really work?

For lowering homocysteine, the human evidence is consistent. A six-week placebo-controlled trial in healthy adults found fasting plasma homocysteine fell 12%, 15% and 20% at daily betaine doses of 1.5 g, 3 g and 6 g respectively, and a meta-analysis of randomised trials in healthy adults reached the same conclusion. The effect is dose-dependent, which is precisely why the label serve matters. Claims beyond homocysteine and methylation support — energy, cognition, fat loss — rest on far thinner ground and should be treated sceptically.

### Who should avoid taking TMG?

TMG is not appropriate during pregnancy or breastfeeding, and product labels in Australia commonly exclude under-15s. Anyone with a kidney condition, elevated cholesterol, or taking prescription medication should speak to their doctor first — betaine has been observed to raise total and LDL cholesterol in some contexts, which matters most for people already managing lipids. If you have a diagnosed metabolic or methylation disorder, this is a conversation for your treating clinician rather than a buying guide.

### Should you take TMG every day?

The trials that produced the homocysteine data used continuous daily dosing for six to twelve weeks, so daily use is the pattern with evidence behind it. There is no established reason to cycle it. The more useful question is if you need it at all: if you are not supplementing NAD+ precursors and your homocysteine has never been tested, the case is weaker than the marketing implies.

### How much TMG should I take with NMN?

There is no human trial establishing an NMN-to-TMG ratio, and any specific ratio you see quoted is invented. What has been studied is betaine at 1.5–6 g daily. A 2,000 mg serve sits inside that range and is the most common capsule dose for this reason. If you want the dosing logic for the precursor side, our [NMN dosage guide for Australia](https://eternalelixir.com.au/nmn-dosage-australia/) covers it, and the [nicotinamide riboside comparison](https://eternalelixir.com.au/best-nr-supplements-australia/) covers the alternative precursor.

### Is TMG powder or capsules better value?

Powder, by a wide margin. In this comparison powders run $0.12–$0.60 per 2,000 mg serve against $0.81–$1.50 for capsules. Betaine anhydrous is chemically identical in both formats, so the premium buys convenience and dose precision, not efficacy. Capsules are worth it only if the measuring step is what would make you quit.

### Is TMG the same as betaine anhydrous?

Yes. Trimethylglycine, TMG and betaine anhydrous are the same compound, and it appears under all three names across these six products. Betaine HCl is different — it is a stomach-acid supplement and will not do what TMG does. Check the panel names trimethylglycine or betaine anhydrous specifically before buying.

Editor's Choice
**Eternal Elixir TMG 2000mg** — the only capsule in this comparison whose single labelled serve (3 capsules) delivers a full 2,000 mg inside the 1.5–6 g range used in the human homocysteine trials, without counting out four capsules of a 600 mg product.

## The Verdict: Which Is the Best TMG Supplement for You?

Betaine anhydrous is a commodity. Once you accept that, the decision collapses into three honest paths.

**If you want the best all-round Australian option:** Bulk Nutrients TMG Capsules at $29.00. Australian-made, lab-tested, $0.81 per 2,000 mg serve, and you take three or four capsules rather than one. It earns the top ranking on our criteria and we would recommend it to anyone not already stacking NAD+ precursors.

**If you are taking NMN or NR and want one supplier:** Eternal Elixir TMG 2000mg at $44.99. You are paying a genuine premium — $1.50 a serve against $0.81 — for a three-capsule serve that hits 2,000 mg exactly, a 90-capsule 30-day bottle, third-party testing with COAs available, Sydney dispatch and the rest of the longevity range in the same order. If that convenience is not worth $0.69 a day to you, buy the Bulk Nutrients and stack it with whatever you like.

**If you want the lowest possible cost:** an imported bulk betaine anhydrous powder at roughly $0.12 per serve. You give up Australian dispatch, local support and on-request batch documentation. For an experienced user who already tolerates TMG, that is a rational trade and we are not going to pretend it isn't.

What none of these paths should involve is paying a premium for a "superior" form of TMG. There isn't one. Verify the panel names betaine anhydrous, check the pack size so you can work out the real cost per dose, and buy on format and price. For the broader picture of where methyl donors sit in a longevity routine, the [rest of our 2026 Australian buying guides](https://eternalelixir.com.au/best-saffron-supplements-australia/) apply the same cost-per-serve method to other categories.

{"@context": "https://schema.org", "@type": "FAQPage", "mainEntity": [{"@type": "Question", "name": "Which brand of TMG is the best in Australia?", "acceptedAnswer": {"@type": "Answer", "text": "On our weighting, Bulk Nutrients TMG Capsules ranks first for the combination of Australian manufacturing, documented lab testing and $0.81 per 2,000 mg serve. Eternal Elixir TMG 2000mg ranks second and is the better pick specifically for people pairing TMG with NMN or NR, because three capsules deliver a full research-range dose in a single serve. If cost per gram is your only criterion, an imported bulk betaine powder beats every Australian option by a factor of five or more."}}, {"@type": "Question", "name": "Where can I find TMG supplements in Australia?", "acceptedAnswer": {"@type": "Answer", "text": "Online only. TMG is not carried by Chemist Warehouse, Priceline or supermarket vitamin ranges. Australian sources are direct-to-consumer brands — Bulk Nutrients, Switch Nutrition and its retail stockists, Eternal Elixir and myBrainCo — plus marketplace imports through Amazon Australia and iHerb. All six products in this comparison ship to Australian addresses."}}, {"@type": "Question", "name": "Does a TMG supplement really work?", "acceptedAnswer": {"@type": "Answer", "text": "For lowering homocysteine, the human evidence is consistent. A six-week placebo-controlled trial in healthy adults found fasting plasma homocysteine fell 12%, 15% and 20% at daily betaine doses of 1.5 g, 3 g and 6 g respectively, and a meta-analysis of randomised trials in healthy adults reached the same conclusion. The effect is dose-dependent, which is precisely why the label serve matters. Claims beyond homocysteine and methylation support — energy, cognition, fat loss — rest on far thinner ground and should be treated sceptically."}}, {"@type": "Question", "name": "Who should avoid taking TMG?", "acceptedAnswer": {"@type": "Answer", "text": "TMG is not appropriate during pregnancy or breastfeeding, and product labels in Australia commonly exclude under-15s. Anyone with a kidney condition, elevated cholesterol, or taking prescription medication should speak to their doctor first — betaine has been observed to raise total and LDL cholesterol in some contexts, which matters most for people already managing lipids. If you have a diagnosed metabolic or methylation disorder, this is a conversation for your treating clinician rather than a buying guide."}}, {"@type": "Question", "name": "Should you take TMG every day?", "acceptedAnswer": {"@type": "Answer", "text": "The trials that produced the homocysteine data used continuous daily dosing for six to twelve weeks, so daily use is the pattern with evidence behind it. There is no established reason to cycle TMG. The more useful question is if you need it at all: if you are not supplementing NAD+ precursors and your homocysteine has never been tested, the case is weaker than the marketing implies."}}, {"@type": "Question", "name": "How much TMG should I take with NMN?", "acceptedAnswer": {"@type": "Answer", "text": "There is no human trial establishing an NMN-to-TMG ratio, and any specific ratio you see quoted is invented. What has been studied is betaine at 1.5–6 g daily. A 2,000 mg serve sits inside that range and is the most common capsule dose for this reason. If you want the dosing logic for the precursor side, our NMN dosage guide for Australia covers it, and the nicotinamide riboside comparison covers the alternative precursor."}}, {"@type": "Question", "name": "Is TMG powder or capsules better value?", "acceptedAnswer": {"@type": "Answer", "text": "Powder, by a wide margin. In this comparison powders run $0.12–$0.60 per 2,000 mg serve against $0.81–$1.50 for capsules. Betaine anhydrous is chemically identical in both formats, so the premium buys convenience and dose precision, not efficacy. Capsules are worth it only if the measuring step is what would make you quit."}}, {"@type": "Question", "name": "Is TMG the same as betaine anhydrous?", "acceptedAnswer": {"@type": "Answer", "text": "Yes. Trimethylglycine, TMG and betaine anhydrous are the same compound, and it appears under all three names across these six products. Betaine HCl is different — it is a stomach-acid supplement and will not do what TMG does. Check the panel names trimethylglycine or betaine anhydrous specifically before buying."}}]}
