Trimethylglycine (TMG), or betaine, has garnered attention for its potential health benefits. Studies suggest that supplementing with TMG at doses of 3,000mg may significantly reduce homocysteine levels by up to 40%, supporting cardiovascular health. Additionally, research indicates that TMG capsules may enhance oxygenation in muscles, promoting increased training volume during weightlifting and exercise, potentially benefiting athletic performance. TMG is also highlighted as an ideal ingredient to combine with a methylated multivitamin for comprehensive cardiovascular health support.
