What is TMG (Betaine)?

Trimethylglycine (TMG, also known as Betaine) is a naturally occurring molecule that helps to facilitate the methylation process. TMG is a ‘methyl donor’ that plays a vital role in regulating homocysteine levels, which supports heart health, liver health, energy production, detoxification, mood balancing and inflammation control.

Just two capsules daily delivers 1,000mg of TMG, making it an easy and convenient way to add this powerful molecule to your daily routine. AgeMate’s TMG capsules are vegan-friendly, gluten-free, and made with the highest purity of ingredients.

What are the effects?

TMG (Betaine) contributes to a range of benefits including enhanced cognitive function, improved liver function, and heart health, while its effects involve acting as a powerful methyl donor that aids in the process of methylation, thus helping to reduce high homocysteine levels, a risk factor for several chronic diseases.

✓ EASY: Addresses core signs of ageing in one simple capsule

Shipping & Regulations


- Free shipping on all orders in Australia over $100.

- All orders are tracked via AusPost

- Metro areas: 7-10 business days

- Rural areas: 8-12 business days

- No payable duties or import fees by you


TMG, like NMN, is approved by the TGA for 'export use' only. This means that TMG cannot be legally distributed and sold within Australia.

For this reason, all orders are fulfilled from our international warehouse in Hong Kong. This is in compliance with the TGA's 'personal consumption' guidelines - allowing import for individual use.

Since all TMG is produced in China regardless, this allows us to keep our supply chain lean and costs competitive for you as the consumer.

We have faith the TGA will at some point authorise its distribution within Australia, but as you might imagine, governmental regulatory bodies must, by their very nature, lag behind scientific advancements.

*No duties or import fees are payable by you.

Return Policy


We know some things take time, that's why we offer a 100 day trial.

If for any reason you're not loving our products, send them back to our Melbourne return facility within a 100 day period for a full refund + return postage.

Questions, anyone?

Simply take 2 capsules per day. It can be taken as a supplement in the morning or at night, with or without food. 

Taking a smaller dose multiple times a day is most effective.

What's the stability and purity like?

We worked with our manufacturer through a 30 day test to ensure our product remain stable even in 40C temperatures. We didn't find any significant degradation in the product.

Our TMG is SGS certified for 99%+ purity.

Where is your TMG made?

Our TMG is manufactured and packaged in China, where there are adequate manufacturing capabilities to produce Resveratrol at scale.

All TMG you see on the market is produced in China. Sometimes you see 'Australian-made' but this refers to it being packaged in Australia, not produced. 

We package in China for efficiency and to provide you with competitive pricing.

How long does it take to start working?

Below is a good timeline of areas where TMG might have an effect:

Day 1-15: Energy, memory and cognition.

Day 15-60: Insulin sensitivity.

Day 60-180: Rate of cellular ageing.

When will I receive my order?

For Australian customers, we ship via tracked AusPost and end-to-end delivery takes around 5-10 business days.

Don't worry, you won't have to pay any import or duty fees.

Can I take TMG with my current medication?

As always, it's best to consult your doctor before taking any new supplement, including TMG.

Sarah Daniell
I feel good

My initial week of using NMN and Resveratrol started with 500mg dose of each. I suffered headaches and felt a little unwell, so I did some research, ordered the TMG (1000mg) and started again. 250mg a day of each, and then over the next four weeks increased it up to 1000mg per day.
I find I have a sense of profound wellbeing, I feel less pushed around by life and can cope better with my everyday. I have an energy and drive that I haven’t felt in a very long time and I am surprised by how well I am recovering from running and gym workouts. I am 54 and looking forward to where this adventure takes me. 🤗

Thank you, Sarah! This is wonderful to hear, really appreciate you taking the time to share your experience :)


Scott Parker
Perfect combination

I’ve been taking NMN for a few months and then added both Resveratrol and TMG capsules.
I ve noticed a vast difference in energy levels and overall wellbeing.

Brilliant to hear, Scott! Thank you for sharing :)


Jane M
6 weeks

Haven’t felt a significant difference on 500mg but told my skin looks great. Will keep taking for now and see as I think you need 3 months to see if there’s a benefit

Thanks, Jane. Try upping the dose if you can. NMN is very dose dependent and you can work your way up to 1,000mg daily. And yes, the body needs 8-12 weeks to fully restore NAD to optimal levels. :)
