US nutraceutical company LifeSmart Nutrition has filed a 44-claim patent in a bid to protect the soft chew delivery system and distinctive manufacturing process used in the production of its Creatine Soft Chews . Creatine supplements, products often linked to boosting athletic performance, form a popular market currently worth over US$600m a year in sales. LifeSmart hope that the soft chews will capture a significant part of this sector, and they use ultra-micronised creatine and sugars to enhance absorption by the body.
