Great Product!

Review by John on May 25, 2022
Really enjoy the flexibility of the unflavored variety. It adds the perfect creamy consistency to smoothies with fruit or whatever your preference happens to be! I’ll be buying this regularly and would highly recommend.

Long Time User

Review by Steve P on May 25, 2022
I have been using Optimum Nutrition for over 15 years now. I have on occasion tried others protein powders, but keep coming back to ON because of the quality and consistency of the product. I use it for breakfast, as well as pre-and post workout.

All-around excellent product

Review by Blake on May 24, 2022
Best whey I’ve ever used. Blends easy with plain water, and tastes great. I mix it with creatine and take it after every workout.

Love this protein

Great taste, easy to mix great value

Consistently great.

Review by Anthony on May 20, 2022
After trying a lot of protein supplements over the years I’ve found that ON has nailed it, consistent, great flavours (strongly recommend the chocolate hazelnut) and fits nicely into a structured diet.

The Best Flavours!

Review by Bradley on May 19, 2022
Great product, really does the trick. I have mine mixed with milk and you wouldn’t even know it was protein powder it had mixed with!

Glad I purchased this!

Review by Anonymous on May 17, 2022
I bought the unflavored whey protein hoping that it wouldn't detract from the flavor of the smoothies that I make every morning...and it doesn't! This powder dissolves well in my shake and I love the fact that it is 100% whey. I am very happy with my purchase and will be buying again.


Review by John Gray on May 16, 2022
This is, by far, the best tasting protein mix I've ever had. Everything else I've tried tasted chalky and too artificial. Optimum is so much more flavorful. Great job to the researchers on this product.
