Protein is an integral part of your diet, so it’s no surprise that high-protein, low carbohydrate products have become all the rage in recent years. As such, Isopure, which claims to be one of the cleanest, purest protein products available, has become an increasingly popular choice for those of us who want added protein in our diets, but don’t want many of the carbohydrates associated with most powders and drinks.
But can Isopure really help you reach your fitness goals? Let’s scoop up the facts and find out.

Isopure Pricing & Refund Policy
While there are no prices available on the Isopure website, their products are available through a number of independent retailers, including GNC, The Vitamin Shoppe, Amazon.com, Bodybuilding.com, and more.
With this in mind, powders appear to range in price between $30 and $140, depending on volume, while drinks range in price between $46 and $50 for 12-pack bottles.
Because Isopure products are sold through third-party companies, refund policies will depend on the retailer.
What Do Other Consumers Have to Say About Isopure?
Isopure appears to be a sub-company of Nature’s Best based out of Hauppauge, NY, although they claim to have been in business for more than 25 years. During our research, we were unable to locate a Better Business Bureau listing for Nature’s best in New York state, and Isopure is not listed at all.
Online customer reviews regarding Isopure products appear to be mostly positive. However, some of the most common complaints we encountered included high price, very bad taste, and indigestion/gas/stomach pains.
What’s the Bottom Line About Isopure?
While most customers seem to be pleased with their Isopure products, there are a few factors you should consider before making your purchase.
First, although Isopure products are advertised as being lactose free, we read one detailed online review that claimed they are not 100% free of lactose-derived ingredients. This means that Isopure should be fine for individuals who are lactose intolerant, but not for those who are allergic to lactose—a small but important difference.
Next, while the Isopure Plus product claims to have been proven to be beneficial for certain medical conditions such as HIV/AIDS, cancer and gastric bypass, they do not appear to be third-party tested for purity. During our research, we read numerous customer reviews that cited big differences in quality between batches, and that some had a distinct chemical odor and/or flavor.
In addition, in order to avoid the carbohydrates associated with traditional sweeteners, Isopure products use sucralose, an artificial sweetener than is FDA approved and is generally considered safe at 9mg or less per day. However, there have been some studies conducted on animals that indicate excessive consumption of sucralose (>1,500mg per day) has been shown to have some serious health concerns.
Finally, the number one complaint we encountered related to Isopure powders was very bad taste. As a result, it’s recommended that you mix the powder with milk (regular, soy, or almond), although this may defeat the lactose-free/low carbohydrate aspect. According to reports, the worst taste is with water.

I tasted the Melon/Apple green drink at Costco and liked it enough to give it a try. It's very refreshing to me, especially straight out of the fridge! It's a great choice for me because I don't always have the time or the inclination to eat, but I want quick protein and energy. This does the trick! It allows me to keep working through lunch, or stave off hunger until I get a chance to eat! I will definitely keep on drinking this.
Bottom Line: Yes, I would recommend this to a friend
