  • bad taste

    Posted by ellen rose on Dec 28th, 2017

    wouldn't reorder. Grainy and not pleasant taste

  • The best protein powder on the market

    Posted by Jan on Nov 15th, 2017

    I'm so very impressed with the Blood Type protein drink. Times when you just don't have time or want breakfast food, this is ideal. It satisfies hunger for a long time, and is good for my Type O body. Definitely feel better when I drink it - and stay with my type foods.

  • Did not like this product

    Posted by Anonymous on Nov 4th, 2017

    Did not care for the taste or gritty texture.

  • Best protein out there

    Posted by colleen on Oct 28th, 2017

    I love the O type protein. It's smooth, not gritty, tastes great and is good for your body. I have turned so many people on to it.

  • Wonderful

    Posted by Uchenna Anagor on Oct 1st, 2017

    I added it to my smoothie with a combination of flax seed and chia seed and it was super delicious.

  • Awesome product

    Posted by Colleen on Aug 4th, 2017

    I have a difficult time finding protein powders that taste good and that are good for me. I love the O type shake. It's not gritty and there aren't any sweeteners added. Great product.

  • This stuff works !

    Posted by Albert Benoit on Aug 4th, 2017

    Allowing for a week to adjust to the earthy flavor, many allergy issues began to fade. It seems to be best for me when mixed with cold black coffee and a a little one square of dark chocolate. This product Does curb my appetite and seems to work as a meal replacement. it also curbs my cravings for sweets . I believe combined with the list of good foods to eat and those to avoid, I will be happier and healthier! I have ordered more which is a good sign for me.

  • Protien power

    Posted by Anonymous on Jul 26th, 2017

    I like this product for the protein that it gives me. I definitely feel a difference. But, I wish it wasn't so chalky.

  • gritty texture, no surprise; belly happy

    Posted by Anonymous on Jul 13th, 2017

    I usually make healthy smoothies, so the powder's grittiness doesn't surprise me. I was just hoping for something smoother. Maybe I should blend it a whole lot longer? I also reduced down to one scoop serving instead of two, and that helps. Again, like all these great D'Adamo products, my Type O stomach feels good & has no complaints, so that's the best part!!

  • The only protein powder I use

    Posted by Tina P on Jun 23rd, 2017

    I use this almost every day. I travel with it and mix it with the Harmonia greens drink. I often add 6 oz of an explorer juice and add another 6 oz of water - usually warm ( a recent occurrence). Sometimes I add some fresh lemon juice too. Every protein powder drink I have tried except this one gives me a migraine. I can use it as a meal replacement particularly if I combine it with one of the nutrition bars. I am great for hours after that with a stable solid energy. I keep drinking water and I can make it through airports and long mornings when I can't get in a breakfast. The convenience of it is my favorite part. It mixes with water too so wherever I go I have protein (and greens). I am an Explorer, O negative. It's one of the first products I tired years ago and I'm still using it. I keep it stocked so I never run out.

  • Decent Protein Blend

    Posted by Sharon Mastin on Jun 5th, 2017

    Would be five stars if I wasn't having a hard time masking the grassy, bland flavor, but other than that it isn't bad. I love the fact that it's protein and as for the grittiness, well, I've had worse.

  • Better for me

    Posted by Gloria Walker on May 7th, 2017

    This so gray! I can mix with fruit or add to my oatmeal or a little to my yogurt! I can feel a difference in my body in using what good for me than the other products I have dumped in the trash!
