Bluebonnet's 100% Natural Dual-Action Protein is sourced from grass-fed cows that are not treated with antibiotics and recombinant bovine growth hormone (rBGH), also known as bovine somatotropin (BST)†. Additionally, this product provides a dynamic blend of whey protein isolate and micellar casein that works throughout your workout and during the recovery phase at night. Whey protein isolate has the highest biological value (BV) of any protein on the market, which refers to a protein that has all the necessary essential amino acids for protein biosynthesis and is fast-acting to support amino acid replenishment required during and after strenuous activities. Plus, this revolutionary protein formula includes extended-action micellar casein that works well beyond strenuous activities to continually rebuild broken down muscle. While both whey protein isolate and micellar casein are rich sources of branched chain amino acids (BCAAs) and glutamic acid, whey protein isolate alone provides the naturally occurring immunoglobulins that help support the immune system, which is transiently depressed during strenuous activity.

Unlike the common practice of using heat-processed whey protein isolate and micellar casein that can denature (render useless) the protein and immunoglobulins, Bluebonnet employs a special low-temperature, microfiltration process that removes excess fat while leaving the protein undenatured and immunoglobulins intact.

For athletes, sports enthusiasts, weekend warriors and active individuals, take Bluebonnet's 100% Natural Dual-Action Protein with:

  • Bluebonnet's BCAAs Vegatable Capsules - for building and repairing muscle.
  • Bluebonnet's Super Fruit Cantaloupe Melon Fruit Extract Vegetable Capsules - that contain naturally occurring superoxide dismutase (SOD) for reducing oxidative stress.
  • Bluebonnet's L-Glutamine Powder - for building lean muscle.
  • Bluebonnet's Nucleotide Complex 500 mg Vegetable Capsules- for producing energy and repairing muscle.

†The Federal Government has determined there is no significant compositional difference in the milk or milk by-products from rBST or rBGH treated or untreated cows.

This was OK, but not my favorite whey protein. I ordered it because it also has the casein, but have since tried a number of other whey protein products and have recently found one that contains both types of whey plus casein plus l-glutamine which I was taking separately until now. So it is more economical for me and I like the taste better than the Bluebonnet.

Thanks for your feedback!

It says "original taste", but it does have some vanilla flavour added. It is subtle so tastes good, but I expected no taste at all, not cool.

Thanks for your feedback!

Taste is neutral no weird smell or aftertaste

I have never liked whey because of unpleasant smell and taste. But because of Health benefits I decided to try one and researched some brands here at iherb. I like it. I have tried it in Cold water. I guess it will work very well in any smoothie, meal or other drink I might want to make. And I could drink it pure. And I might even try it in tea and coffee, but I am not sure it will dissolve well. I'll be back when I've tried it. I recommend this! As far as I understand it is not heat processed. I might also like to write the Company to find out what temperature it is heated to. This whey contains both whey and casein, so I guess this is usually what is recommended for evening.. And pure whey for morning and day.. but to each their own.

Thanks for your feedback!

Not bad but...

Posted by iHerb Customer on Apr 27, 2014 | Verified Purchase

So I only got this product because the Natural original flavor was out of stock. I figured since its by the same company I would give it a try. Since I mostly put my protein powder into smoothies, I thought the strawberry flaor would be more neutral than chocolate. When I first opened it, I was surprised how the consistency was different than the original flavor. This was more like a sand consistency. The smell reminded me of strawberry chewing gum, or some kind of candy. It blended easily enough, but the taste was way to sweet for me. Also it seemed to have a wierd taste, maybe from the stevia? While I finished off the whole package, it just wasn't for me.

Thanks for your feedback!

The best out there.

All the Bluebonnet whey supplements are the best most purest I have ever found which is why I make sure to never run out.
