    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. .

    How many times a day should my son be drinking this? He is under 16.
    A shopper

      He can drink it as much as he wants. It's not meant to be used as a meal replacement necessarily but this is a good brand and is okay to drink it everyday if he likes to

    Lena S

      I don't recommend this kind of supplement for kids. Natural food is better than these chemicals.

    Vikas D

      1-2 times a day. 1 in the morning or 1 before bed. Definitely 1 after workout

    Ashley L

      Once a day!! No more than once I suggest

    Michelle C

      Once a day should be plenty.

    I need to follow a strict gluten free diet due to celiacs disease, and this product is labeled gluten/wheat free, but lists "cookie bits" in the ingredients. Just wanted to double check and see if the cookie bits are actually gluten free?
    Kara F

      I will apologize up front...I, myself, do not suffer with celiacs disease - to be really safe, it would be best to contact the manufacturer - they should be able to determine just how 'gluten free' the product is. I wish you well in your search!

    Susan B

      I'd recommend buying a different flavor. You'd be safe with anything else.

      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.

      Are protein shakes “good” for you?

      Protein shakes can be an excellent addition to a well-rounded diet and healthy lifestyle. Research has shown that supplementing with protein can support athletic performance, post-workout recovery, weight management, muscle maintenance, and muscle growth.

      Can protein shakes support weight gain?

      Protein shakes may support weight gain if they contribute to a calorie surplus in your diet.

      Can protein shakes support weight loss?

      Research has shown that protein-rich foods temporarily rev up your metabolism and can help make you feel satiated longer, which may contribute to weight loss.

      Are protein shakes "good" for women?

      Supplementing with protein is as beneficial for women as it is for men in supporting muscle growth and maintenance, recovery, and performance.

      How can protein supplements benefit my muscles?

      Protein supplements provide the nutrients your body needs to stimulate muscle protein synthesis and support recovery post-workout.
