IsoFue premium whey isolate with low fat and sugar content, fast absorption, vitamin D and DigeZyme® digestive enzymes

IsoFue contains one of the purest and most easily absorbed proteins in the form of whey protein isolate, with up to 83% high-quality protein content. The core of the protein is the unique Volactive® whey isolate processed using gentle CFM (Cross Flow Microfiltration) membrane technology, which allows to preserve the natural structure of whey proteins and their high biological value. Thanks to its filtration technology, Volactive® is low in fat and sugar and is a high-quality, easily digestible, top-class whey protein. Moreover, it is a source of calcium, vitamin D and contains a blend of Digezyme digestive enzymes, including lactase.

 

This premium whey protein isolate boasts an exceptionally high degree of filtration. Compared to whey concentrate, it is typically a cleaner and more concentrated source of protein, contributing to muscle growth and maintenance, which is particularly appreciated by strength athletes on a cutting diet. In addition, it also contributes to the maintenance of normal bones and muscle function, thanks to the aforementioned vitamin D and calcium. Vitamin D itself also supports the function of the immune system. Another great advantage is the fact that the product is also GLP-1 friendly.

 

Due to its properties, IsoFue is ideal for supplementing protein before or after training. However, the protein can be consumed anytime during the day in a delicious drink with water or milk. It is also great for adding high-quality protein to fitness desserts, breakfast cereals, or smoothies. In short, IsoFue is perfect for anyone looking for a high-quality and clean source of protein without extra calories.

    Otherwise, I struggle to find a good isolate that does not cause digestive issues, but I have been using this one for 6 months, in vanilla and strawberry flavors, and I am truly delighted with the results.
