It helps your body make its own creatine, protects muscle cells against heat and dehydration, keeps homocysteine in check and, in meta-analysis, raises maximal strength. This guide covers the mechanism, 8 sport and 8 health benefits of TMG, and the three SCN\u2122 formulas that contain it.<\/p>\n<\/div>\n<div class=\"quick\"><b>Quick answer:<\/b> Trimethylglycine benefits come from two jobs: it donates methyl groups (powering creatine, carnitine and neurotransmitter synthesis and lowering homocysteine), and it acts as an osmolyte that protects cells from heat, dehydration and acid stress. Result: more strength and power, better endurance in the heat, and faster recovery.

It was first isolated from sugar beet \u2014 hence &#8220;betaine&#8221; \u2014 and is found in beetroot, spinach, wheat bran and seafood. Your body also makes it from choline. Typical dietary intake is 100\u2013400 mg\/day; sports doses are 1.25\u20132.5 g\/day.<\/p>\n<h2>How does TMG work? Two mechanisms, one athlete<\/h2>\n<div class=\"cards\">\n<div>\n<h4>Mechanism 1 \u00b7 Methyl donation<\/h4>\n<p>In the liver, betaine-homocysteine methyltransferase transfers a methyl group from TMG to homocysteine, producing methionine \u2192 SAMe. SAMe is the universal methyl donor used to make <strong>creatine<\/strong> (the final step of creatine synthesis), <strong>carnitine<\/strong>, phosphatidylcholine, adrenaline and dopamine. More TMG = more endogenous creatine and lower homocysteine.<\/p>\n<\/div>\n<div>\n<h4>Mechanism 2 \u00b7 Osmoprotection<\/h4>\n<p>Cells accumulate TMG to hold water and stabilise proteins under heat, dehydration and hypertonic stress \u2014 exactly what happens in a muscle fibre during hard exercise. The result is better cell hydration, preserved enzyme function and reduced damage.<\/p>\n<\/div>\n<\/div>\n<h2>What are the 8 sport benefits of TMG?
