Optimum Nutrition Gold Standard 100% Isolate, Rich Vanilla, 2.91 Pounds, 44 Servings (Packaging May Vary)

ON's Isolate Protein is one of the best options for those looking for high-quality, easy-to-digest protein. It has a high protein content per serving, is low in fats and carbs, and mixes perfectly without clumps. The taste is delicious, and it doesn’t cause stomach discomfort. Ideal for post-workout recovery or daily supplementation. Excellent quality and guaranteed results!

I’ve tried upwards of 10 big brand protein powders and this one takes the cake. High protein content without high calories, sugars or carbs. Blends effortlessly with zero clumps. Maintains a fairly thin consistently and doesn’t taste chalky at all, unlike most protein powders. No weird aftertaste. It’s a breath of fresh air for anyone with textural sensitivities. At this price point, it’s a great bang for your buck too.I strongly prefer their whey isolate because it’s just higher quality powder AND it’s easier on the stomach. Doesn’t make me gassy at all.

The flavors are absolutely amazing! The sweetness isn’t too strong, and unlike other protein powders, the artificial sweetener doesn’t bother me at all. It’s also super easy to digest and gentle on my stomach—no bad reactions like I’ve had with other expensive protein powders. Usually, I can’t use more than half a scoop, but with this one, I can easily add two scoops to my protein shakes or pancake mix without it being overpowering. Highly recommend, and I’ll definitely be buying again!

This is a good isolate protein with good macronutrition. The only gripe I have with it is that it is excessively sweet.

Best protein powder I’ve ever tried!Taste of the chocolate is so soft and not strong and it’s not granny at all!

Great taste. Mixes very well and is light. Will be buying again.

Vanilla is great.Chocolate Bliss tastes like hazelnut - ghastly. No amount of strawberries or bananas can make the chocolate drinkable.

The product itself is great. Quality item and flavor IS not as artificial as other brands; I have been using ON for many years.My problem is that I GOT THE WRONG FLAVOR; IT SEEMS THAT AMAZON DISCONTINUE THE FLAVOR THAT I CHOSE AND THEN THEY SEND WHATEVER FLAVOR THEY HAVE.I'm not returning the item because I will lose the promotional code that I use, and still I will not get the original flavor that I want it.
