I've noted what I would describe as a sharp smell when I open a container of Recoverite or Hammer Whey. What is the cause and is this normal?
The strong scent naturally occurs from the amino acids that make up the whey protein isolate in both Recoverite and Hammer Whey, and it is completely normal. One reason why the scent may be more pronounced in these products is because virtually all of the fat and lactose have been removed, yielding a more potent amino acid profile—over 90% actual protein—as compared to whey protein concentrate, which only yields, at the most, about 75-80% actual protein. The other reason is because we only use natural flavors in both products; these "mask" the naturally occurring smell of the amino acids much more subtly than artificial sweeteners, which we definitely do not want to include in the products.
