Trimethylglycine (TMG), also known as betaine, is a compound found naturally in foods like beets, spinach, and whole grain bread, with an average daily intake of 100 to 300 milligrams. But what happens when we boost our intake through supplements? Research shows that TMG supplements have the potential to significantly improve muscle performance and may also play a role in reducing the risk of dementia.
TMG and Muscle Performance
TMG has garnered attention for its potential to enhance muscle and athletic performance through several mechanisms:
- Increasing creatine levels: Creatine is crucial for short bursts of energy during high-intensity activities.
- Accelerating ATP recycling: ATP serves as the primary energy source for our cells, and its efficient recycling can delay fatigue.
- Regulating cell hydration: Proper cell water content is essential for optimal function.
- Enhancing muscle protein synthesis: Key for muscle growth and repair.
A 2017 systematic review of seven high-quality trials found that TMG supplementation led to increases in strength or power in two studies, with the remaining trials showing no benefit. However, the positive outcomes were observed when TMG was combined with high-intensity exercise, suggesting that TMG's benefits are maximized in conjunction with physical training, particularly resistance and power training.
Further evidence of TMG's efficacy was demonstrated in a 2021 randomized, double-blind, placebo-controlled study involving professional soccer players, where TMG supplementation was found to improve performance metrics such as one rep max, VO2 max, and sprinting performance.
TMG and Cognitive Health
Beyond muscle performance, TMG holds promise in the realm of cognitive health, particularly in reducing dementia rates. A 2020 systematic review highlighted the role of high blood homocysteine levels as a predictive factor for developing dementia. TMG, with its three methyl groups, can donate these to help convert homocysteine into methionine, effectively lowering homocysteine levels in the body.
Despite a 2014 meta-analysis of 11 large trials showing no significant cognitive benefits from lowering homocysteine with B vitamins alone, our understanding has evolved. Combining TMG supplementation with a diet rich in all essential vitamins and minerals, and possibly adding Omega-3 supplements, could provide a more effective strategy in preventing Alzheimer's disease and other forms of dementia.
TMG Dosage and Safety
For exercise performance, most studies utilize a TMG dosage between 2 and 5 grams per day. However, due to limited research on long-term effects, a more conservative approach of 1 gram per day is advisable. Initial safety data is reassuring, showing no side effects after several weeks of supplementation.
Conclusion
TMG supplements offer a dual benefit: improving muscle performance when combined with exercise and potentially reducing the risk of dementia through its homocysteine-lowering effects. While more research is needed, particularly on long-term effects, TMG supplements could be a valuable addition to a comprehensive health and fitness regimen. Ensuring a balanced diet and considering additional supplements like Omega-3s may enhance these benefits even further.
