 Nature's Best Isopure


Nature's Best Isopure is the first product of its kind to feature an impressive 50 grams of 100% pure ion exchange whey protein isolate. This meal replacement drink mix also includes branched chain amino acids (BCAAs) leucine, valine and isoleucine, conditionally essential amino acid glutamine and 24 essential vitamins and minerals. Isopure is specially formulated for athletes to help achieve positive nitrogen retention (stored muscle protein) and support muscle growth.

Isopure's whey protein molecules have been isolated from milk protein and purified to obtain the purest product of its kind. It's so pure that the protein dissolves clear enough to see right through it. Isopure's concentrated source of whey proteins including beneficial beta-lactoglobulin and alpha-lactalbumins promote muscle gain. The addition of immune factors bovine serum albumin, immunoglobulin (an antibody) and lactoferrin (an antimicrobial) boost immunity and wellness.

Amino acids are required to build the proteins used in the growth, repair, and maintenance of muscles. The BCAAs leucine, valine and isoleucine are essential amino acids that can't be made by the body. Although glutamine is an amino acid that can be made by the body, it's considered a conditionally essential amino acid if demand exceeds the body's ability to produce it. Certain conditions, such as intense exercise, surgery or infections can deplete BCAA and glutamine levels.


Isopure is a lactose free, fat free and aspartame free meal replacement drink mix. Each packet contains 50 grams of pure whey protein and 1 gram of sugar. It's instantized so it can be taken anywhere and mixed with a spoon. Isopure features a chocolate flavor and is conveniently available as a 20 count pack.

Isopure has the following benefits:

  • 50 grams of 100% pure ion exchange whey protein isolate
  • Promotes positive nitrogen balance
  • Enhances muscle growth
  • Boosts immunity and wellness


People who are allergic to dairy products should avoid whey protein.
No side effects have been reported with the use of BCAAs and glutamine. However, people with ALS (amyotrophic lateral sclerosis), depression, Reye's Syndrome, heart, kidney or liver disease should not supplement with amino acids without consulting a physician.

People with pre-existing medical conditions or taking medication should not supplement with Isopure without consulting a physician.

I have been using Isopure for a couple years now. Have been very happy with the results. However the product NEEDS to be used alongside an exercise training regimen and can not be used as a diet supplement alone.

I have enjoyed ISOPure because of the ability to review the product easily. I have been using Nature's Best for some time now, and have been very satisfied. I do agree that all items in the food or supplement categories should have nutritional labels.
In the defense of Not Recommended for Weight Loss. No supplement should be used strictly for Weight Loss alone. Weight management comes from diet and exercise and the proper use of protein supplements. High protein and exercise does stimulate weight loss and muscle growth. Meal replacement supplements are not meant to just be ingested and expect miracles.
