Active Ingredients

BCAAs

Brached chain amino acids, or BCAAs, are building blocks used for muscle growth and repair.

When taken around the time of exercise they have been shown to reduce the breakdown of muscle, as well as contribute to quicker recovery (1).

Glutamine

Glutamine is another amino acid which has been shown to improve muscle development.

It may be unnecessary, however, to use alongside BCAAs (2).

Citrulline Malate

Citrulline is a compound that increases levels of nitric oxide.

This prompts a dilation of the blood vessels, improving blood flow, endurance, and pumps (3).

Citrulline malate may also reduce muscle soreness.

The effective dose is 6-8g.

Taurine

Taurine is an amino acid that may reduce fatigue (4).

It improves water and nutrient uptake into the muscles.

Coconut Water Powder

Coconut water contains electrolytes, which have been shown to improve performance and rehydration when taken around the time of exercise (5, 6).

Who Takes It?

Athletes wanting to reduce muscle breakdown and improve their recovery and growth will enjoy using R1 Train BCAAs.
