Whey Protein Isolates

Whey Protein Isolates are the purest and most “clean” form of whey protein available. The initial whey protein has been filtered to a high degree removing concentrates and impurities.

This is what makes whey protein isolates the perfect post-workout protein. Extremely fast amino acid release to assist in the rapid repair of damaged muscle tissue post-workout, try R1 Protein Isolate as an example.

Another great use for Whey Protein Isolates is for anyone who is lactose intolerant. Most whey protein isolates are inherently lactose-free, thus no potential stomach discomfort from any lactose being present. When you supplement with a quality WPI such as Precision Whey Isolate by Precision Nutrition, you can be assured you are getting one of the purest protein supplements available, free of any impurities or excess/unwanted calories from sugars and fats. Perfect for anyone looking to maintain a lean physique or who is looking at weight loss as their goal. At Supplement Mart we stock a huge range of Whey Protein Isolates, so will be sure to have something suited to your needs.
