Reformulated "new" Creamy Vanilla
Initially unhappy with the apparent formula change and flavor, I procured a 3lb jug of ISOPURE's creamy vanilla. I have to say that this reformulation is much closer in taste to the "old" formulation, so I am back as their customer once again.

Improved, but doesn't beet the original
The formula definitely has changed recently. Isopure then sent me two replacement batches of the new formula, which improved and no longer has the salty grainy bits in the bottom. The new formula still doesn't really meet the flavor quality of the original powder, but it's significantly improved. Still feels like I'm drinking a "diet" protein powder. If consumers have any say, I would highly recommend Isopure go back to the original gray container formula.

No bloating!
I have a hard time with protein powder causing me to bloat but this brand hasn’t caused me to have that problem. It’s also not chalky and tastes okay.

The Best!
I drink this every day and absolutely love it. I've tried other protein supplements, and nothing compares with Isopure.

Not the best, not the worst l
[This review was collected as part of a promotion.] Mixed well but the taste was lacking. I feel like the flavor was compromised in order to get it lower carb. Overall, it's not the worst protein I've ever had but certainly not the best. Maybe a different flavor would be better but the vanilla is just lacking for me.

Great flavor
Great flavor! I have only used my vitamix to mix into a coffee protein shake, so I can’t vouch for how well it mixes with a spoon. But it does great in a blender! I’ve used it for about a month, and I’m already seeing an improvement in my nail strength. Keeps me full until lunch!

Hunger gone for few hours
[This review was collected as part of a promotion.] I received isopure zero carb vanilla. I liked the flavor because it was tolerable and didn’t tasted like medicine as other proteins I have tried in the past. What was not clear enough were the instructions but it was simple to mix just with water, I would mix it with something else like smoothies or milkshakes for better tasting.

Delicious!!
Best vanilla flavor I’ve ever had. I’m normally a chocolate kinda girl, but isoprene Creamy Vanilla is really outstanding. (Although Dutch Chocolate is also excellent.). I love that Isopure is easily mixed with water or milk and is high protein.

Good macros
[This review was collected as part of a promotion.] The ingredients are great and the macros are amazing as well but it has a weird aftertaste that I did not enjoy, however I use it in smoothies and it's not so bad

Best protein powder out there.
Best protein powder out there. I love that is mixes easily in a shake bottle, no foam or clumps. The isolate is easier to digest. it cooks and heats well for hot drinks or food. Mixes instantly in yogurt. I just wish they had more flavors!

Delicious & reliable
I’ve been using isopure for several years and it has always been a great product. Only downside is that it has gotten increasingly expensive
