Powders that use more whey concentrates than isolates are less expensive. It’s true that you get less protein per scoop, but the price increase for isolate does not necessarily add up to you getting more protein per dollar. Plus, some whey protein isolate manufacturing steps can harm some of the beneficial whey protein fractions such as beta-lactoglobulin, alpha-lactalbumin, and bovine serum albumin peptides, which provide performance and physique-enhancing benefits as well as antioxidant and immune-boosting properties.
The gentle filtration that WPC-80 undergoes leaves these all in place. However, remember that whey concentrate contains more lactose, so if you have an intolerance, it may not be your best choice.
Adding soy protein to your shakes can help keep costs down. Soy is about half the price of whey and digests only a little slower. Furthermore, soy’s amino acid profile complements that of whey to provide benefits that whey protein alone can’t. These include increased growth hormone secretion, enhanced nitric oxide (NO) production, and antioxidants that have been shown to enhance muscle recovery. To end the debate once and for all, soy does not raise estrogen or decrease testosterone levels in men, as a recent review study confirmed. Replace about half a scoop of whey with soy protein isolate. It not only provides enhanced muscle-building benefits, but will also allow your jug of whey to last longer.
Buying powders online is typically cheaper than buying them in the store. And if you go to Muscle & Fitness Store, you’ll find great prices on all your favorite protein powders, and monthly specials that really cut prices down.
