Betaine, also known as trimethylglycine, is a crucial compound in human physiology, primarily functioning as a methyl donor and an osmolyte. By donating methyl groups, betaine plays a vital role in converting homocysteine to L-methionine, ultimately aiding in creatine production. This process is essential for muscle strength, endurance, and overall training volume.
As an osmolyte, betaine protects cells and enzymes from physiological stressors like heat and dehydration. Studies, including one from the University of Connecticut, have shown that daily doses of betaine significantly improve muscular power and strength. Additionally, betaine aids in fat metabolism in the liver, promotes muscle protein synthesis, and may enhance nitric oxide levels.
This multifaceted amino acid derivative is not only essential for athletes seeking to increase power and endurance but also plays a pivotal role in overall cellular protection and metabolic health.
