Shopping for protein powder at Costco? Here’s what to look for. Whole foods always come first but if you’re grabbing a protein powder, ingredients matter. Most options include natural flavors and seed oils, but the real difference is in the sweeteners.
Flip the tub, read the label, and choose the option with the cleanest ingredient list. Stevia is a better choice, while sucralose, aspartame, and carrageenan are ones to avoid. Your body will thank you later.
