ICON Nutrition Whey Protein Powder — Cinnamon Vanilla Swirl — High Protein, Grass Fed, Low Carbs & Fat, Complete Amino Acid Profile, Cold Shakes or Mix with Foods — 960g, 30 Servings

Free Shipping

Why We Love It

Pure, high-quality protein sources.
Ideal for muscle building.
Promotes optimum gut health.

Main Highlights

100% WHEY PROTEIN POWDER: We can safely say 100% whey because our protein powders do not contain anything but whey concentrate and whey protein isolate, the purest form of whey that exists providing less fat, cholesterol and lactose than any other protein types. We don't use milk protein or pea protein to 'fill' out our formula like other brands. This only brings the profits up for them and the quality down for you. You won't find anything like that in our protein shakes
MORE PROTEIN PER SERVING: Our 100% whey is protein powder evolved. Per serving provides 25G of muscle building protein and less than 2G carbs making it a perfect choice for low carb dieters or weight-sensitive athletes such as runners, cyclists, gymnasts and those that compete in physique sports
CONTAINS JUST 0.1% SUCRALOSE: We don't like providing unwanted calories to a person's diet and reduced sweetener is better for promoting healthy gut flora. We're proud to be able to say per protein shake contains just 0.1% sucralose. Not many brands can say that, but we can. Our low carb protein powder also features DigeZyme, digestive enzymes ensuring optimum gut flora & health
GRASS FED IRISH WHEY PROTEIN POWDER: All our whey protein powders come from hormone free Irish cows that are grass fed year round thus yielding significantly more naturally occurring branch chain amino acids (BCAA's) per serving than other lean diet whey protein powder products
WHEY ISOLATE PROTEIN POWDER: When it comes to building and repairing muscle not all protein powders are created equal. Why? Simple, it's to do with absorption. Our protein powder is specifically formulated for FAST and MAXIMUM uptake whatever time of the day you take it. What makes this so is that we use the purest WPI (whey isolate) available which tops the bio-availability scale rating at 159, making it the best form of protein that our body's digestive system can make use of
