Alternatives to creatine
The authors analyzed forms of creatine for sale on Amazon.com and evaluated if the advertised claims are supported by the available scientific evidence, and analyzed the cost per gram of the forms of creatine. A total of 175 creatine supplements were included and the authors reported the total creatine content per serving, form(s) of creatine in products, product claims, and prevalence of products third party certified. The identified products contained 16 forms of creatine other than CM, including GAA.
