Health Notes

Whey Protein

Whey Protein
  • Reliable and relatively consistent scientific data showing a substantial health benefit.
  • Contradictory, insufficient, or preliminary studies suggesting a health benefit or minimal health benefit.
  • For an herb, supported by traditional use but minimal or no scientific evidence. For a supplement, little scientific support.

Our proprietary "Star-Rating" system was developed to help you easily understand the amount of scientific support behind each supplement in relation to a specific health condition. While there is no way to predict whether a vitamin, mineral, or herb will successfully treat or prevent associated health conditions, our unique ratings tell you how well these supplements are understood by the medical community, and whether studies have found them to be effective for other people.

For over a decade, our team has combed through thousands of research articles published in reputable journals. To help you make educated decisions, and to better understand controversial or confusing supplements, our medical experts have digested the science into these three easy-to-follow ratings. We hope this provides you with a helpful resource to make informed decisions towards your health and well-being.

This supplement has been used in connection with the following health conditions:

    This is the first supplement I have used and I couldnt be happier. I have turned two others onto it as well. It shows fast results, and quickens your recovery time. Only con is the taste -- From what Ive heard it tastes better then other shakes, but there are days where I have to plug my nose to drink it. Ha. But its worth it ! Highly recommend people to try it.

    Comments about GNC GenetixHD™ ISO-DEFINE™ - Berry Sorbet:

    I picked up some recently and so far it's great. it's slightly pricy, but it's more than just a protein powder. My favorite part is that it has no artificial sweeteners.. This is one of the few powders with real sugar. The taste itself is pretty good, it's not anything amazing. The powder mixes pretty easily with just a fork. If you are looking to build muscle get this. It has everything necessary to build muscle without any negative ingredients.
