Is Isopure a Good Protein?

Although the name suggests an isolate, pure product, Nature's Best Isopure is a powdered protein supplement that also contains carbohydrates and fat. Although Isopure is higher in calories than some other protein products, the product can be beneficial for your muscle-building goals. Isopure is available in three flavors: Creamy Vanilla, Dutch Chocolate and Strawberries & Cream. While Isopure may be beneficial for some, consult a doctor prior to using any supplements.


Isopure can be a good protein for you because it is rich in calories. Each serving of Isopure contains 300 calories, which comprises 15 percent of the daily suggested intake of 2,000 calories. If you want to gain muscle, Isopure can be a good protein to use, as it supplies more calories than you'd burn in an hour of weightlifting, 219. If you want to lose weight, Isopure may not be a good protein for you; whey protein isolate contains 101 calories per serving. In fact, switching from one serving of Isopure to one serving of whey isolate would save you 1,393 calories per week, enough to lose more than a third of a pound.


Isopure is rich in protein, as each serving contains 50 g of this nutrient. This amount of protein is an entire day's worth of protein, so Isopure can support a high-protein diet. High protein diets can enhance your muscle growth, as protein contains amino acids, the building blocks of muscle. Additionally, research from the October 2009 edition of "Nutrition, Metabolism and Cardiovascular Diseases" indicates that high-protein diets can aid in promoting fat and weight loss.


Isopure has a high carbohydrate content, as each serving of the product contains 25 g of carbohydrates. Carbohydrates provide fuel for activity, so Isopure can be beneficial for pre-workout use. However, Isopure may not be ideal for post-workout recovery; nutrition researcher Dr. John Berardi suggests post-workout meals should have a carbohydrate:protein ratio of 2:1, and Isopure has a 1:2 ratio.


Isopure is low in fat, with each serving providing 1 g of total fat and .5 g of saturated fat. This can make Isopure a good protein choice because it is suitable for a range of diets, including low-fat meal plans. Additionally, Dr. John Berardi suggests that post-workout meals be low in fat to facilitate quick nutrient absorption, so Isopure can be used as part of your after-training meal.


Many protein powders do not contain added vitamins, but Isopure is a rich source of vitamins, with one serving providing half of the daily suggested intakes for vitamins A, B-6, B-12, C, E and K.

Mineral Content

Isopure is rich in minerals, providing 60 percent of the daily suggested intake of calcium as well as 50 percent of the daily recommended intake of folate, biotin, magnesium, zinc and copper, among other nutrients.
