Greater numbers of athletes are choosing foods and supplements made with more natural ingredients. And while the government hasn’t yet defined exactly what ‘natural’ is, shoppers recognize what they want when they see it: products devoid of artificial flavors, synthetic sweeteners, and manmade colors.

NATURALLY FLAVORED PROMASIL checks all the boxes. Made with the same sustained release blend as our original formula, NATURALLY FLAVORED PROMASIL provides fast-acting whey proteins, intermediate coverage from egg white and goat’s milk proteins, and slower-digesting casein proteins for a longer lasting amino acid stream. Better still, this elite level blend keeps things real with natural flavors, stevia and monk fruit sweeteners, and no added colors.
