Customers review summary

The Dymatize ISO100 protein powder delights customers with nostalgic cereal and dessert inspired flavors that make shakes feel like a treat. Its smooth mixability, fast absorbing formula and roughly 25 grams of protein per serving are appreciated for curbing cravings and blending easily with water or milk. A few customers note some flavors run too sweet or report a light aftertaste, yet most say the taste and convenience keep it in rotation.

Price Gouging at Its Finest
$30 per pound of protein and the cajones to jack up the price for a "BOGO" is price gouging at it's finest. Not surprised considering the latest acquisition by a capital investment group. The cost of protein nowadays is out of control and should not be supported. Get your protein intake elsewhere.

Love flavor but disappointed with new macros
I used to use this flavor and honestly I love how tastes even with water BUT my new tub says 110 calories instead the regular 120 calories before. So, I'm just concerned to which one is NOW (August 2026) the right macros on this powder. Just kinda disappointed with the confusion

Terrible vanilla tast since recent federal changes
This product used to be great, now it is a terrible vanilla flavor after a recent couple batches. It should be removed from the shelves. I was advised this by support after a recent inquiry about the change. . "Thank you for contacting Dymatize Nutrition.We appreciate you reaching out with your product concern, However, There is a federal FDA ban, along with state regulations, on the use of Red 3 and certain other food colors in food and beverages starting January 1, 2027.

Is the whey iso 100 good for lactose intolerant people?
Pete

  Since it's a hydrolyzed whey isolate, virtually all lactose has been removed. Most of our clients who have mentioned having lactose intolerance have not had issues with this product at all.

Brenda

  It’s a whey ISOLATE, so yes.

Is the whey is 100 good for people that are lactose intolerant?
Pete

  For me the regular whey protein would cause digestive issues and feeling bloated. Since I switched to ISO100 I have yet to have a problem with any bloating or stomach issues. I would consider it a good option if you are lactose intolerant. I have been using it for over 4 years.

Matthew L

  Since it's a hydrolyzed whey isolate, it has had virtually all lactose removed. We've had several clients who have said they're lactose intolerant use this product without issue.

Brenda

  Yup it is. We are lactose intolerant and love this stuff!!! Did a lot of research to find this one.

Raimund B

  Lactose free
