Our award-winning range meets the highest standards and has received thousands of 5-star reviews. We prioritise transparency, efficacy, and customer satisfaction, ensuring each product offers exceptional quality.
We independently test our TMG powder via HPLC for purity. We also test for heavy metals, micro and moulds.
Our high-purity Trimethylglycine (TMG) powder is sourced from a trusted global network of long-term manufacturing partners, all certified to cGMP, ISO 9001, and FSSC 22000 standards. Each batch undergoes comprehensive purity and heavy metal testing at an independent, APVMA-licensed laboratory in Australia. Final packaging takes place in a cGMP-certified facility to ensure the highest levels of quality, safety, and product integrity.
Our TMG Powder is proudly certified carbon neutral under the Climate Active standard, Australia’s leading program for voluntary climate action. Through the use of verifiable carbon credits, we offset more emissions than our product produces, creating a net positive environmental impact. These offsets contribute to high impact initiatives such as the Tambopata Bahuaja Biodiversity Reserve, Rimba Raya Biodiversity Reserve, and the Karlantijpa North Savanna Burning Project.
Frequently asked questions
TMG (Trimethylglycine) supports key biological processes in the body by acting as a methyl donor. It plays an important role in methylation, a vital process involved in energy production, liver function, cognitive health, and the regulation of homocysteine levels. TMG also assists cellular hydration and helps maintain overall metabolic balance, making it a valuable nutrient for daily performance and long-term wellbeing.
TMG is best taken in the morning, ideally with or after food. This timing supports daytime energy, methylation activity, and nutrient metabolism. If you're combining it with methylation cofactors (like B vitamins or NMN), taking them together can enhance synergy. For those using higher doses, splitting into morning and early afternoon servings may offer more stable support. Avoid taking TMG late in the day, as its mild energising effect may impact sleep in sensitive individuals.
We recommend consulting with your healthcare professional before taking TMG during pregnancy or breastfeeding to ensure it is safe for you and your baby.
TMG is free from gluten, dairy, lactose, peanut, soy and egg.
Yes, our TMG powder is 100% vegan friendly.
TMG is generally considered safe, but it can interact with certain medications, especially if you are taking medications that influence methylation, liver function or homocysteine levels. If taking medications, we recommend speaking to your healthcare professional before starting a new supplement regime.
Blend 1 scoop (approx. 1g) into 150–200ml of water, protein, juice or liquid of your choice.
TMG (Trimethylglycine) has a mildly sweet, slightly earthy taste with no bitterness or aftertaste, making it easy to mix into water, juice, or smoothies. Its pleasant flavour means it can be taken on its own or blended with other supplements without affecting the overall taste.
Yes, TMG is safe for long-term use, but we recommend consulting your healthcare professional before starting any new supplement.
TMG supports cognitive function by assisting healthy methylation, a process involved in neurotransmitter synthesis and cellular energy. By helping to maintain balanced homocysteine levels, TMG plays a supportive role in overall brain health and mental clarity.
TMG supports longevity by promoting healthy methylation and helping to regulate homocysteine levels, two important processes involved in healthy ageing and cellular function.
Methylation is essential for DNA repair, gene expression, detoxification, and neurotransmitter production. As we age, methylation efficiency can decline, impacting everything from brain function to cardiovascular health.
By donating methyl groups, TMG helps maintain optimal methylation balance, especially when paired with NAD+ precursors like NMN. It also acts as an osmolyte, supporting cellular hydration and resilience under stress, further supporting overall wellbeing and healthy ageing.
