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.

Please Note: Due to recent market conditions, whey protein prices have surged significantly beyond our control. We remain dedicated to maintaining the highest quality and will adjust prices down as soon as market values stabilize. Thank you for your understanding and continued support.

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.

Best unflavored whey isolate protein

Do your searching and you’ll be glad you came here if you’re looking for whey protein that’s unflavored and in bulk, can’t beat the deal

High Quality Protein Isolate

This is my 1st time ordering whey protein isolate from Z Natural Foods. It appears to be quite pure. The last company I dealt with was pretty good, but this one clumps less, mixes easier and has less odor/taste.

High quality protein, annoying subscription

I've tried both the plain and the vanilla flavor whey isolate. The plain is superb. The vanilla is OK... not the best vanilla I've had. Stick with the plain.

One other annoying thing is, when you order on a "subscribe & save" basis, they don't send you any email notice when your next shipment is coming up. They just inform you after they sent it. Which means you often end up with more than you need.
