Sportfood recommend PhD BCAA on training days for any athlete looking to protect and repair their physique PhD Nutrition BCAA's, the exciting first product in the brand new "Recovery range" have been designed to the specific 2:1:1 ratio required to optimise the effects of Leucine, the most important of the three BCAA's. Muscle protein synthesis (muscle growth and production) PhD BCAA's are vital to protein synthesis (the ability to build muscle) and also vital in reducing muscle damage. Vitally, when we workout strenuously with weights, we oxidise amino acids (use them to fuel our training). BCAA oxidisation is rapidly promoted by exercise, so when we train hard, we use BCAA's. If we do not replace or keep topping these BCAA's up before, during and after exercise, we run the risk of increasing muscle damage indicators Creatine Kinease (CK) and lactate dehydrogenase (LDH) and missing the opportunity of recovering in the optimum time.
