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
✓ AFFORDABLE: Costs less than a coffee a day
✓ CONVENIENT*: Perfectly measured 500mg caps, no self-measuring needed.

What's The Science On TMG?

Methyl Donor Supplement

Trimethylglycine (TMG), commonly known as betaine, is a naturally occurring compound found in various food products like beets, spinach, and whole grains. It's a derivative of the amino acid glycine and has three methyl groups attached to it, hence the name trimethylglycine. TMG is classified as an osmolyte and a methyl donor, playing a crucial role in cellular function and integrity, as well as critical biochemical processes within the body.

TMG is involved in the conversion of homocysteine, a harmful amino acid, to methionine, a useful one, by donating one of its methyl groups. This process is vital for cardiovascular health, as elevated homocysteine levels are linked to increased risk of heart disease and stroke. In addition, methylation is also a key process in DNA repair and replication, neurotransmitter synthesis, and detoxification, among others, which underlines the wide-ranging effects and benefits of TMG in the body.


TMG Targets: Homocysteine Conversion

Benefit: Heart and cardiovascular health, DNA repair, anti-inflammation and age reversal

Nisha Singh (Singapore, SG)
TMG (Betaine) for Methyl Donation

I had started taking TMG along with NMN, each morning.
I was having sleepless nights the days I took them both.
I eliminated NMN from my routine and took TMG only. This helps me sleep a lot better.
Great product, will buy soon again as running out now. Thank you AgeMate.

Turning back time

Since taking the TMG along with Berberine and of course the youth elixir Age Mate I feel it has elevated my experience for the better. It has been a trying time for me at moment as husband diagnosed with GBM grade 4 so to say a terrible time.I am feeling like I am coping well thinking clearly knowing that I am getting everything my body needs. I am putting this down to all the products I currently take. I have lost weight not sure due to shock of diagnosis or the added Bererine either way feeling ok otherwise.

Hi Robyn,

Thank you for sharing your experience with us during such a challenging time.

We're deeply sorry to hear about your husband's diagnosis and the hurdles you're facing. It's truly inspiring to hear that despite these difficulties, you're experiencing a positive impact from our products. Your resilience is commendable.

Regarding the weight loss, it's likely attributed to Berberine, which aids in improving metabolism and effectively managing weight.
Additionally, the Daily Longevity Blend contributes to enhancing insulin sensitivity, which can also support weight management efforts.

Please know that we're here to support you in any way we can, and we're sending you strength and positive thoughts as you navigate through this difficult period.

If you have any questions or need further assistance, please don't hesitate to reach out. Wishing you and your husband all the best on your wellness journey.

TMG Capsules

Have felt no difference yet. But have had to halve daily dosage due to TMG being out of stock and not sure when or if you will get more stock in

Hey A.M,

The impact of our Daily Longevity Blend can differ from person to person due to variations in metabolism. Some individuals may experience its effects more rapidly than others.

Even though our Blend includes 500mg of NMN, 50mg of Psterostilbene (a 5x more bioavailable alternative to Resveratrol), and a methyl donor complex, some individuals, depending on their NAD levels, may require a higher dose, such as NMN or all three products (some may need 1000mg of each or more). Without reaching the appropriate dosage, achieving the desired results may be challenging.

If you're still willing to give it a try, you can opt to either increase the Blend dosage or supplement it with our NMN (or all three powders separately added to the blend) and assess the outcomes. Best to increase gradually by 125mg or 250mg every 7 days, ensuring your body tolerates it well.

Additionally, do not take it with hot drinks as this can degrade the NMN. It's best to consume it 15-30 minutes before or after having a hot drink.

Also, I apologise that you had to take the TMG dose is half due to the TMG being out of stock as it's being popular these days, we already have the TMG in stocked and we will ship your order as soon as possible.

Please let us know, if you have questions or in need of help. We're happy to assist.

Scott Bullock (Sydney, AU)
Not Sure Yet

I'm not sure what's working yet as it's only early days and I do take an extra amount of supp's also! One thing though is the powder packets are very small to get your hand into so I've bought containers to pour the powder into. The caps would be my next go to I guess.

Thanks for your feedback, Scott! We're actively working on a new and better packaging which we're hoping to release in the near future after undergoing some tests :) If you need help with anything, just let me know.


Aaron Becker (Wellington, NZ)

Excellent product, will get powder next time as it suits me personally better, I didn't see it advertised last time, even tho it was there , works Excellent with agemate NMN

Hi Aaron, thanks for rating us 5-stars and for sharing your feedback! These two supplements work together synergistically to support cellular health and longevity, and I'm glad they're working perfectly for you!

Let me know if you have questions.


Sarah Daniell (Whakatane, NZ)
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 (Auckland, NZ)
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 (Palmerston North, NZ)
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. :)
