Nature’s Best Isopure Low Carb Review

Nature's Best Isopure Low Carb

The supplement company Nature’s Best calls themselves the puritans of protein.

They’ve apparently been working for more than 25 years to produce products with the cleanest, purest protein. And one of these products is Isopure Low Carb.

This particular protein shake uses whey protein isolate to eliminate excess calories and cut the formula down to only 3 g carbs. So is Isopure Low Carb really one of the purest forms of protein around?

Isopure Low Carb Ingredients

Isopure Low Carb basically consists of one ingredient: whey protein isolate.

Whey protein is one of the strongest and purest protein sources. Unsurprisingly, it’s the most popular as well. In a poll at, 41% preferred whey protein isolate above all other protein sources, and another 36% preferred regular whey protein. This means whey protein gets roughly 77% of the protein market share.

Whey protein is quickly absorbed, has a high concentration of muscle building BCAAs, and is highly concentrated in muscle tissue.

Whey protein isolate is specially formulated to yield a higher protein percentage. The protein is filtered so that it is free of lactose, carbs, fats, and cholesterol. Athletes prefer it because it helps restore the body to a muscle-building state after a workout.

But which whey protein forms does Isopure Low Carb specifically use?

Ion-Exchange Whey Protein Isolate

This form of whey protein isolate is created by taking a whey protein concentrate and running it through an ion exchange column. This allows for the highest protein content, but unfortunately it may deplete other healthy components.

Microfiltered Whey Protein Isolate

Microfiltered whey protein isolate means that the protein level remains high while the important nutritional components are maintained.

Isopure Low Carb Functions

With pure protein forms, Isopure Low Carb is a great tool for athletes to replenish necessary amino acids for muscle growth.

But can Isopure Low Carb be used as a meal replacement for those who want to lose weight? Well, it contains roughly the amount of protein that a sedentary adult would need in a whole day.

Consequently, it should fill you up and provide necessary vitamins and nutrients, without adding unneeded carbs.

Isopure Low Carb Protein Content

As I mentioned, Isopure Low Carb has a whopping 50 g of protein. This may seem impressive, but it’s important to note that not everyone can digest the full 50 g in one serving. This could cause bloating and subsequent discomfort.

If you don’t want the full 50 g of protein in one serving, you could always take 1 scoop instead of 2.

Isopure Low Carb Reviews

It’s clear that for the most part, customers love Isopure Low Carb. E’liza said, “I have been using protein powders for over 20 years and have to say that this is by far the best tasting that I’ve ever had. It’s low in carbs and also lactose free . . . I am very pleased with this brand and this will probably be the last protein powder that I ever buy!”

Those who did not like the product usually commented that certain flavors were not appealing. The Dutch chocolate flavor was generally well received, but some users did not like the strawberries and cream or creamy vanilla flavor.

Isopure Low Carb Buying Options

Prices vary depending on size and flavor, but Isopure Low Carb is available at various locations such as Supplement Warehouse, Advantage Supplements, and Nutrition Wholesalers. A one pound container sells for as low as $20.99 at

Isopure Low Carb: The Verdict

Isopure Low Carb is a pretty high quality protein powder for those looking to stimulate muscle tissue growth. But with so much protein, dieters could be exceeding their daily caloric intake goal, and even experiencing painful indigestion. You may want to keep shopping around before making your final decision.
