About Product

Whey protein isolate is a concentrated form of whey protein, the liquid part of milk that separates during cheese production.

First discovered in the early 1900s, whey protein isolate is a source of essential amino acids, which are the building blocks of proteins.

It is low in lactose, fat, and cholesterol, making it a popular choice for those looking to support lean muscle mass and their overall health.

Whey protein isolate is commonly used in protein shakes, smoothies, and other protein-rich foods. It can also be added to meals and snacks for some extra protein.

In addition to its protein content, whey protein isolate contains various vitamins and minerals, including calcium, magnesium, and phosphorus.

Protein Profile (Percent of Total Protein):

  • Beta-Lactoglobulin - 50%
  • Alpha-Lactalbumin - 22%
  • Bovine Serum Albumin - 2.0%
  • Immunoglobulin - 4.0%
  • Lactoferrin - <1.0%
  • Lactoperoxidase - <1.0%
  • Glycomacropeptide - 20%

Allergens: Milk

Our Ultra Whey Isolate is instantized, with a small amount of non-GMO sunflower lecithin, which means it will mix in liquid much easier than whey concentrates, which are not instantized.

Suggested Use:

Mix 6 level tablespoons / 1 ounce (28 grams ) with 12 ounces of cold water, skim milk, or juice and thoroughly mix in a blender, shaker, or fork for 20-30 seconds. For best results, consume 1-2 servings daily, with one serving post-exercise. It can also be blended into your favorite smoothie.

Mixing suggestions: To increase flavor and nutritional profile, combine with our organic extra-rich cacao, banana flakes, and strawberry powder.

The best!

I’ve been using znatural foods products since 2013. I started out using other protein powders they offered like pea, rice, and hemp proteins mixing them together and creating my own but I was diagnosed with Crohn’s disease and I find I process the whey protein better. I tried all of the whey options and for me the ultra whey protein isolate has the best taste. I love all their products and give them partial credit for my health and healing journey.

Goood Stuff

I had gotten use to buying other brands which had different flavorings, but was always concernex about the added sugars. Even stevia, monk fruit and the such are seen as your liver as a sugar and that is not good. So I went back to this brand which is 100% sugar free…. what could be better! To parapharse an old movie line: We don’t need no stinking sugar!

Mostly good

I like that the taste is a little more neutral and has a bit more protein per servings than the one I bought before which was New Zealand grass fed and had some somewhat of a powdered milk taste. I do wish the bag was not so tall because when it gets half full you need to stick almost your entire arm in the bag and it gets all full of powder, kinda messy in that regards. I have never seen such a tall narrow bag used for whey protein as I had bought the Optimum Nutrition brand for years and it is a bit wider and not as deep. I changed to Z Natural because the price is much better.
