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.

Taste is good. Has a bit of after taste similar to a ginseng flavour but overall it has all the nutritional items that i need.

With the USD it worked out to be about 5$ a bottle it was on the expensive side.

GNC Canada doesn't carry it.
