The science behind the product: 

Branched-chain amino acids 

BCAAs are a group of three essential amino acids, and these nutrients are usually obtained through protein-rich foods. While they are a popular supplement for strength or endurance athletes, their muscle-support benefits can be had by anyone. 

BCAAs can aid in energy and even fat loss, but the main benefit of BCAAs is their ability to boost muscle growth. Research shows that BCAAs help to both maintains and build muscle strength and endurance, support physical performance and brain function, and promote muscle recovery. (1,2)

The blend of BCAAS in ON Gold Standard BCAA Train + Sustain contains 2,6 mg of L-leucine, 1,2 mg of L-isoleucine, and 1,2 mg of L-valine. 

Rhodiola rosea 

Results from clinical trials suggest that Rhodiola rosea has beneficial effects on physical and mental performance, promoting the production of energy and fighting fatigue. (3-7) 

Electrolytes 

Electrolytes are minerals found in your blood that help regulate and control the balance of fluids in the body. These minerals play a role in regulating blood pressure, and muscle contraction and keep your system functioning properly. The big three electrolytes are sodium, potassium, and magnesium. 

ON Gold Standard BCAA Train + Sustain offers 374 mg electrolytes per serving. 

Other nutrients 

Vitamin C and zinc contribute to the normal function of the immune system, and magnesium contributes to the reduction of tiredness and fatigue.
