If you haven't already done so, I highly suggest you take a look at that "Other Ingredients" list on your protein powder. You'll be surprised at what's in some of those top-rated, highly recommended brands out there. Be sure to take a look at NOW Foods for your supplement needs in the future.
Below is a picture of all the great products from NOW Foods I won from a contest on another blog. I loved each and every one of them, including the backpack with it's super soft padding!! They were generous enough to gift me with Chocolate Protein Powder, Eve Multi Vitamins, Energy Nut Mix, and 3 boxes of their Slender Sticks, which are these awesome little packets of powder that add vitamins and all natural flavor to your boring water!
