Commonly used as a food additive, dipotassium phosphate is a water soluble salt. Because salts are important in the metabolic and electrolyte systems in the body, dipotassium phosphate is sometimes sold as an athletic supplement.
Primarily used by weight trainers and body builders, dipotassium phosphate is thought to help improve performance while also speeding recovery time. It helps to replace the salts lost during an intensive period of exercise.
Dipotassium phosphate stimulates the nervous system, and helps to stabilise blood pressure. Because it helps to deliver energy to the muscles, it is thought to make for better execution of short bursts of rapid and repetitive movements, such as those involved in sprinting or weight lifting.
Dipotassium phosphate is also thought to reduce the build-up of lactic acid in muscles, helping to prolong endurance and slow down the arrival of muscle fatigue.
This means that dipotassium phosphate may potentially be of benefit to sportspeople involved in endurance sports, as well as quick fire sports.
Dipotassium phosphate is available as a powder, which can be mixed into food or drink or used as part of a shake.
