The Short Answer
Betaine anhydrous (trimethylglycine) functions as a methyl donor and osmolyte, supporting cellular hydration and energy metabolism. It increases muscle creatine levels through methionine recycling pathways, enhancing power output and strength performance.

Betaine Anhydrous (TMG) — botanical close-up
Health Benefits
Enhances power output by increasing muscle creatine levels, which fuels explosive movements. This results in improved performance in high-intensity activities. - Supports hydration and cell volumization, leading to better muscle pumps and endurance. - Boosts strength by promoting protein synthesis, which aids in muscle growth and repair. - Reduces fatigue by lowering homocysteine levels, improving overall energy metabolism. - Enhances cognitive function by supporting neurotransmitter synthesis, which improves focus and mental clarity. - Promotes heart health by supporting healthy homocysteine levels, reducing cardiovascular risk. - Improves body composition by supporting fat loss while preserving lean muscle mass.
Origin & History

Natural habitat
Betaine Anhydrous, also known as trimethylglycine (TMG), is derived from sugar beets and other plant sources.
“Traditionally, betaine has been used in animal feed to improve growth and performance.”Traditional Medicine
Scientific Research
Studies suggest Betaine Anhydrous can enhance muscle endurance and strength, with some evidence from RCTs supporting its efficacy.
Preparation & Dosage

Traditional preparation
Dosages typically range from 1.5 to 3 grams per day. Consult a healthcare provider before use.
Nutritional Profile
How It Works
Mechanism of Action
Betaine anhydrous donates methyl groups to homocysteine via betaine-homocysteine methyltransferase (BHMT), regenerating methionine for creatine synthesis. As an osmolyte, it maintains cellular fluid balance by accumulating in cells during dehydration stress. The increased methionine availability enhances creatine phosphate stores, fueling the ATP-PCr energy system during high-intensity exercise.
Clinical Evidence
Multiple randomized controlled trials with 12-23 participants show 2.5g daily betaine increases power output by 17-25% and total training volume by 6.5% over 1-2 weeks. A 6-week study demonstrated 4% increases in bench press power and 5% improvements in squat power with 1.25g twice daily. However, some studies show minimal effects on body composition, and research is limited by small sample sizes and short durations.
Safety & Interactions
Betaine anhydrous is generally well-tolerated with mild side effects including nausea, stomach upset, and diarrhea at doses above 4g daily. It may increase homocysteine levels in individuals with MTHFR gene variants, potentially affecting cardiovascular health. No significant drug interactions are documented, but it may enhance the effects of methylation-dependent medications. Safety during pregnancy and breastfeeding has not been established.

Frequently Asked Questions
What is the optimal betaine anhydrous dosage for muscle performance?
Research supports 2.5g daily taken as a single dose or split into 1.25g twice daily. Studies showing performance benefits used doses ranging from 1.25-2.5g daily for 1-6 weeks.
How long does betaine anhydrous take to work for strength gains?
Power output improvements can occur within 1-2 weeks of supplementation at 2.5g daily. Maximum strength and muscle volume benefits typically develop after 6-8 weeks of consistent use.
Can betaine anhydrous be taken with creatine monohydrate?
Yes, betaine and creatine work synergistically since betaine supports endogenous creatine synthesis through methionine recycling. Taking both together may provide superior strength and power benefits compared to either supplement alone.
Does betaine anhydrous cause water retention or bloating?
Betaine may cause mild intracellular water retention that enhances muscle volumization rather than subcutaneous bloating. This osmolytic effect contributes to improved muscle pumps and performance rather than uncomfortable water gain.
Is betaine anhydrous the same as betaine HCl for digestion?
No, betaine anhydrous (trimethylglycine) is used for athletic performance and methylation support, while betaine HCl contains hydrochloric acid for digestive support. They have different mechanisms and cannot be used interchangeably.
