Love this stuff!!!
I have tried almost all the flavors of this and absolutely love it. I do not care for the shake style protein drinks so this is amazing for me. I am preparing for gastric surgery and know that this is going to be a huge help for me post-surgery.

Clear pure protein 40g- GREAT go-to option for protein!
I love having this option for protein after a workout. It is not every day that I want a creamy protein shake. So this is wonderful. It also lasts a little longer after opened and is easy to drink anywhere. After a light work out I may drink half then and half later. 40g of protein, plenty of flavors – and the green tea flavor has green tea powder (I think one carbohydrate).

Isopure blue raspberry
I love Isopure. It’s way too expensive though. I only buy it when GNC has a clearance or when I get a lot of rewards built up along with a large cashback on ebates to make it affordable.

Way too sweet. Sweetened with sucralose, an artificial sweetner. Even worse, they don’t tell you the amount. This is NOT a healthy product and the marketing is misleading.

Taste good and has good protein quanity
November 14, 2017
I had gastric bypass and after 2 bowel obstructions, so Isopure is my main food source. I mix flavors together and I feel I'd die without it! I can't drink the thick, milky texture protein shakes, gross! Isopure RTD is a lifesaver, literally!

Outrageously good taste
Wish the bottles were not glass, however. I have had too many broken bottles in shipment. Buy this product in store.

Nilda M on Apr 30, 2018
BEST ANSWER: Not really. They say not for children on the bottle, but I suspect it is because of the coloring used. The protein, bcaa, and glutamine can be a helpful supplement after a strenuous workout.

What does keep out of reach of children mean? What age is ok? Over 18?
A shopper on Mar 26, 2018
BEST ANSWER: I would think the warning with regard to children is due to the amount of protein. It's quite a large amount for smaller children. Because the color is pretty and it is raspberry, a child not realize this is an adult protein drink. Anyone over 18 should not have any issues, unless they have some medical reason why they must limit their daily intake of protein. In such a case I would check with a physician first.
