A clear look at what this product is designed to support.
TMG is a naturally occurring methyl donor used by practitioners in individually compounded formulas where targeted trimethylglycine supplementation is considered appropriate.
Trimethylglycine provides methyl groups used in normal one-carbon metabolism and the methionine cycle
Betaine participates in the BHMT pathway, donating a methyl group for the normal remethylation of homocysteine to methionine.
Betaine also functions naturally as an organic osmolyte, helping cells maintain normal volume and protein stability under osmotic stress.
Contains pure trimethylglycine with no added excipients, allowing practitioners to tailor the amount within individually prepared formulations.
A closer look at the formula.
Orthoplex TMG contains one ingredient only: pure trimethylglycine, also known as betaine anhydrous, supplied as a practitioner compounding powder.

One level included scoop contains 4.9g trimethylglycine, also known as betaine. No additional active ingredients are included.

TMG acts as a methyl donor through betaine-homocysteine methyltransferase (BHMT), contributing to the conversion of homocysteine into methionine.

BioConcepts lists no manufacturing or incidental excipients, making this a straightforward single-ingredient powder for customised practitioner compounding.
Orthoplex TMG is a pure trimethylglycine oral powder supplied specifically for extemporaneous compounding by suitably qualified healthcare practitioners. It provides a flexible methyl donor ingredient for individually designed practitioner formulations.
Orthoplex TMG is intended for individually prescribed extemporaneous compounding, so the amount and preparation method should be determined by a suitably qualified healthcare practitioner.
Use only the amount of TMG specified in the personalised formulation prepared or prescribed by your healthcare practitioner.
Use the included scoop as a measuring reference—one level scoop contains 4.9g TMG—but do not assume a full scoop is your prescribed dose.
Keep the powder tightly closed below 30°C in a cool, dry place away from direct sunlight, and follow your practitioner's instructions for the finished compound.
“TMG provides a pure, excipient-free trimethylglycine source for practitioners requiring flexible methyl-donor supplementation within individually designed extemporaneous formulations.”
Contains trimethylglycine only, with no manufacturing excipients listed by BioConcepts.
Betaine donates a methyl group through BHMT during normal homocysteine-to-methionine remethylation and one-carbon metabolism.
The 100g oral powder allows the practitioner to individualise the amount of TMG rather than relying on a fixed-dose finished supplement.
