  • Right for me even though I'm a type A

    Posted by V Wiedemann on Jul 28th, 2019

    I was frustrated with the Type A Protein Blend powder because it didn't keep me satisfied at all. This was back when Dr. D's forum was still active, and Lola suggested that I try the Type O powder. Since I am a nonnie, and one of those almost unclassifiable Explorer types, some straight A products are not what I need.

    So, I tried one container of the Type O powder and it most definitely works better for me for a breakfast smoothie that will keep my tummy from yelling (hungry) at me for at least two hours, which is the best I can do with any kind of liquid/protein blend. I usually add another kind of protein, like brown rice protein powder and/or grass fed whey powder, along with my organic soy milk and whatever fruit and greens I choose for that day.

    Only 4 stars because I still need to eat something solid in a couple hours, but that's not particularly the fault of Dr. D's formula.

    My best friend is also a Type A nonnie Explorer and I suggested she try the Type O powder. It works best for her also!

  • Delicious and filling

  • Protein Blend Powder

    Posted by Diane Roy on Jul 14th, 2019

    This is the first time I've used a protein powder. I find it mixes smoothly. I can tell it's in my smoothie because it becomes a little thicker, but not gritty. It doesn't add any odd flavor. I give it a thumbs up!

  • Protein powder for O type

    Posted by Anonymous on Apr 25th, 2019

    Worst tasting protein powder I have ever tried and as a bodybuilding competitor, I have tried a lot. Will not buy again. I cannot even try to choke it down, it’s that bad!

  • Beat Protein for my smoothies

    Posted by Anonymous on Jan 23rd, 2019

    I love to add this to my smoothies. I get enough fruits and vegies in my smoothie, so this is a great additional protein without all the extras.

  • love the Type O Protein powder

    Posted by Deneen C Fasano on Nov 17th, 2018

    I have trouble digesting most of the protein powders on the market. I get gas or bloating from them. The Type O Protein Blend Powder is made from rice protein and I have no problem digesting it. No bloating, no gas. It mixes great in my morning smoothie!

  • Powdered taste

    Posted by Anonymous on Sep 26th, 2018

    The product does seem to curb appetite, if you can get past powdered tasted. I tried a variety of ways, even adding fresh fruit, the powdered taste is overwhelming. I just have to chug it down quickly. But the fullness feeling seems to last for hours compared to other protein supplements

  • Doesn't hold me

    Posted by Julia Metcalf on Aug 19th, 2018

    This shake doesn't hold me from breakfast to lunch like others do. I'll keep buying it, but I'll need to find something more to keep me going.

  • Best protein powder available

    Posted by Gwen on Aug 15th, 2018

    This is the best protein powder ever! After starting an intense 3-month weight training program, I didn't think that I would be able to do it. But, after researching and learning that protein powder helped in recovery I figured I would give this a try. I was astonished at how much energy this protein gave me after working out. I managed to complete the program and build a good amount of muscle. I will be restarting the program again thanks to following the ER4YR diet and this powder. There is no flavor or sugar which is a real advantage. You can add your compliant fruit and sweetener. Please try it. You will not be sorry.

  • Finally a protein easy on my stomach!

    Posted by Anonymous on Aug 4th, 2018

    No it's not the best taste, but I add a tablespoon of carob powder and half a banana. Plus I only use one scoop. I'm used to it now.

  • Love this Protein Powder

    Posted by Linda on Jul 18th, 2018

    I use this powder with water and pineapple juice. Throw in some frozen fruit instead of ice and that's it!!!
