The last time we actually saw Optimum Nutrition release a new flavor for its first Platinum Series supplement, Platinum Hydrowhey, was way back in 2013. The brand added Chocolate Mint to its menu, which took the product up to a total of six flavors from its original set of five. Well over two years later Optimum is now back with a seventh flavor for the protein in Red Velvet Cake Platinum Whey. For now the brand has only unveiled the new option, and saying that fans can expect to see it in stores sometime soon.
