Great flavor
This is a really simple way to meet your protein needs. Everyone has their preference for using it and mine is adding it to milk. I really like the flavor. They nailed it on this one.

Nice Light Option for Hitting Protein
Not a strong taste but not a bad one either. Great for adding into recovery protein shakes and for a lower carb option when just trying to hit the protein goal for the day.

Isopure Natural Vanilla Bean
The Natural Vanilla Protein Powder has been my favorite for years and i use on almost a daily basis. I saw that you have now changed formulas so I bought the one pound bag to try. It is awful absolutely not like the old version, it doesn't seem to blend as well, it seems a lot sweeter and overall the taste is just not good, maybe it is the Stevia because that has a terrible after taste. I ended up throwing this packet of the new version away. Luckily I found a place that still has some of the original formula so I bought 3 3lbs containers, but once that is gone I will have to find a new Protein Powder to use. Very disappointed that you ruined something that was so good. Buyer beware this is not what you had before.

Easy to Mix, great nutrition !
[This review was collected as part of a promotion.] This was perfect for quick and on the go protein. It dissolved so easily and the taste was good enough alone to even mix only with water. I love that it’s GMO free and the chocolate flavor is yummy and not chalky.

Still good but why the change to stevia???
Former recipe used monk fruit extract and was delicious. Current formulation uses stevia and now has an aftertaste. Why the change??? Still a great product for its simplicity but prior recipe was better.

Good macros
[This review was collected as part of a promotion.] So I really did like the macro nutrients on this however, the taste was a little bland. I wish it would’ve tasted a little bit more like vanilla. It did mix very well with milk and water and a pack of doing was convenient.

LOVE! I am picky about vanilla flavor and this is by far my favorite protein powder on the market. Clean ingredients, good taste, mixes well.

Thumbs down
The flavor is just not good. Strawberry is good but vanilla is lacking.. water made it even worse

Not good but not horrible
Taste is lacking. Even with the least amount of water it’s like you took a spoon of pudding and stirred it in water. Not at all filling. Love that it’s not full of junk though so that offsets the negatives.

Decent
[This review was collected as part of a promotion.] Got the strawberry flavor and made according to the directions with water. Powder dissolved easily in my shaker bottle. The taste wasn't overly sweet but a little thin. I didn't want to add more powder but would try again with milk instead of water.

It works!
[This review was collected as part of a promotion.] This is probably the only protein powder that I’ve used that works. It tastes great (not gritty like most powers), and doesn’t leave me feeling bloated or sluggish. I’d for sure try another flavor.

Not yes feel .
[This review was collected as part of a promotion.] I can't feel the effect and taste of it. I have waited a lot and used up the gift you gave me but maybe it is not effective for me. or not the right time.

Good Whey Protein
[This review was collected as part of a promotion.] Easy to mix protein! Made a shake with this powder and it was delicious. Had to add extra fruit to mask the taste a bit. Easy packaging and scoop to measure serving size. Great protein!

Great post-workout drink that mixes well with matcha, leaving me energized and refreshed all day
[This review was collected as part of a promotion.] I drink this Isopure Low Carb Protein Powder after every workout mixed with my matcha instead of coffee, and it has been a game-changer for me! The mixability is smooth, and I feel energized and refreshed throughout the day. The taste is subtle and doesn't overpower the matcha, making it a perfect post-workout drink. I love how it's naturally sweetened and low in carbs, which fits perfectly with my diet. Highly recommend for anyone looking to replace their coffee or add a boost to their workout recovery!

great taste with benefits
[This review was collected as part of a promotion.] this is a smooth creamy non grainy mix that blends well. i add a frozen banana, water, ice and left over coffee to mine. the only real complaint is the whey in this as i’d rather it be plant based. overall not a bad option
