ProteinOne Reviews

Our satisfied customers have found ProteinOne solutions to be remarkably effective and user-friendly, as evidenced by the following reviews:

ProteinOne’s Chocolate Peanut Butter whey is unreal! I got the 2lb tub from Amazon for $30, and it’s my post-workout staple. With 24g protein and only 2g sugar, it fits my keto diet perfectly. It mixes so smoothly in my shaker with 10oz water—no clumps, just creamy goodness. The flavor is rich without being too sweet, though I noticed a slight sucralose aftertaste, as one review mentioned. It keeps me full for hours, and my recovery’s improved. I’m trying Cinnamon Bun next—love the variety!
Lana
I’ve been using ProteinOne’s Birthday Cake flavor for a month, and it’s a game-changer! The 5lb tub from iHerb was a steal, and 24g protein per scoop helps me hit my macros. It blends effortlessly with almond milk for a dessert-like shake, perfect for my morning routine. No amino spiking is a huge plus—I trust what I’m getting. The only downside is the sucralose can taste artificial if I use too much powder, but diluting it works. Free shipping sealed the deal!
Tara
ProteinOne’s Vanilla Ice Cream whey is my go-to for daily shakes. I bought the 2lb tub from proteinone.com, and at 24g protein and 130 calories, it’s ideal for my weight training. It mixes like a dream in my blender bottle, no grit or clumps, and tastes great with just water. I use it pre-workout for energy and post-workout for recovery. Some reviews noted sweetener issues, but I find the flavor balanced. My only wish is for more vegan options. Highly recommend!
