Safety

Safe at 1.5-2.5g per day. Helps with strength and power output. No significant side effects reported in clinical studies.

💡

For comparison

100g of beets contains about 250mg of betaine. For a sports dose (2.5g) you'd need to eat 1 kilo of beets. Not impossible, but a supplement is more convenient.

⚖️

Dosage by weight and gender

The effective betaine dose for sports performance is 2.5g per day, split into 2 servings of 1.25g (Cholewa et al., 2014). Body weight does not affect the optimal dose. There are no relevant differences between men and women. The effect builds up over 2 weeks of daily use. The 2.5g dose is based on clinical studies on strength and power output.
