We always hear (especially from gym rats, like me) that protein powders are necessary for that extra oomph in the gym.
It’s true, and science has backed that up.
But I understand why some are hesitant even to try taking protein powders -- most of them taste like straight-up trash (harsh, but I feel you), especially the unflavored protein powder options.
If you’re still unsure which flavorless protein powder will tickle your taste buds, we’ve done the research and assembled some of the best-unflavored protein powders on the market today.
Believe me, there’s a lot of them. And this list may encourage you to at least try a protein powder that you’ll finally like.
Ready to give your shake and smoothie an extra energy kick? Now, let's get into the list!
