Product Information

90 days Supply


The Science in Sport HMB is formulated with 1000mg of HMB.


HMB (or beta-Hydroxy beta-methylbutyric acid) is an active metabolite of the branch chain amino acid Leucine.


Benefits of Science in Sport HMB


There is increased interest around HMB supplementation and its role in preventing muscle catabolism. During exercise, muscle protein breakdown occurs, and a small amount muscle tissue is metabolised for energy production. Both of these processes can have negative outcomes on performance. The ability to reduce the magnitude of these processes may result in improvements during exercise, in particular, endurance performance.


HMB is tested under the Informed Sport Certification program. This approach involves testing every single batch of SIS finished product, which leaves the Company’s factory, screened against the 2018 World Anti-Doping Agency (WADA) list. Banned substances including steroids are tested to the level of 10 Nanograms per gram, and stimulants to 100 Nanograms per gram. Batches (sampled at the beginning, during and end of each product batch) receive the recognised and respected Informed Sport* certificate and Science in Sport provides the documentation to athletes on request.
