Betaine Anhydrous in Pre-Workouts
The Bottom Line
Betaine Anhydrous is included in pre-workouts to support strength, power, and endurance — though the research on its impact is mixed, with systematic reviews landing on a 'possible benefit' rather than a definitive one. Studies have most commonly supplemented 2.5g per day, and the PwrRanks database shows that pre-workout formulas follow that pattern with an average dose of around 2.5g. It's an ingredient where the market and the research are well-aligned on dosing, even if the evidence of benefit isn't conclusive

PwrRanks Take
Betaine Anhydrous appears in around 50% of formulas in our database — most prevalent in Pump formulas, with lower inclusion in the Everyday and High Stim categories. When it's included, it's commonly dosed at or near 2.5g, making it one of the more consistently dosed ingredients across the market. For power and strength-focused lifters it's a worthwhile addition to a formula — for general fitness users, it's a nice-to-have rather than a must-have.
- Well-dosed across the market
- Performance evidence is mixed
- Worth prioritizing for power/strength athletes

What Betaine Anhydrous Actually Does
Betaine Anhydrous is a pump support ingredient that works in two ways: as a methyl donor and as an osmolyte.
As a methyl donor, betaine supports the body's recovery, energy, and muscle-building processes by donating methyl groups to key biological pathways.
As an osmolyte, betaine helps muscle cells regulate water balance and stay hydrated under stress. This may contribute to a fuller muscle feel and a better pump during training.
Think of betaine as a creatine-adjacent support ingredient rather than a fast-acting pump driver like L-Citrulline. Its benefits are more likely to show up with consistent use over time as tissue levels build — not something you'll feel immediately.
