According to the Journal of the International Society of Sports Nutrition, 24 active male students took part in the double-blind, randomized, placebo-controlled study.
During various power, muscle endurance and anaerobic power exercise tests over a two week period, subjects given BetaPower showed a significant improvement in lower body muscle endurance and quality of the workout compared to those participants that were not given supplementation.
Mika Paulamaki, global business manager, BioActives, Danisco, Finland, told NutraIngredients-USA that betaine is approved in the US and several Asian countries. However, it is currently not allowed in the EU as it requires novel foods approval. He confirmed that the company is currently working on the application, but it is not known when this will occur.
“Our strategy is to market products that are backed by clinical studies,” said Paulamaki. “The research results together with the previous performance studies support the use of natural betaine as a valuable ingredient for health and sports nutrition products.”
