91% protein.
No other supplement
has more.

If you’re comparing numbers, Iso-Smooth™ isn’t just good,
it’s categorically elite. Its astonishing protein content of 91% is among the highest of any protein supplement ever made and its leucine, BCAA, and essential amino acid proportions are high enough to have it included in the conversation of purest proteins available today.

THE JURY IS IN. PROTEIN SUPPLEMENTATION WORKS.

Thanks to decades of scientific research, it’s universally accepted that protein supplementation has real, significant, and meaningful positive effects on muscle mass, muscle strength, and muscle quality in people of all ages.

WHAT IF ENOUGH
ISN’T ENOUGH?

In North America, the reference daily intake (RDI) of protein is just under half a gram for every pound of bodyweight. However, a high number of academic experts in protein metabolism strongly recommend consuming as much as twice that amount to maintain muscle size, and as much as three times that amount to maximize weightlifting-induced muscle growth.

NOT ALL PROTEINS
ARE CREATED EQUAL.

In terms of muscle growth, scientific research has clearly identified that whey protein is superior to soy, casein, egg, and vegan protein when measuring absorption, delivery, and stimulation. Simply put, whey protein is the single most effective muscle-building protein.

All Whey. Always. 100% of the protein in Iso-Smooth™ is whey protein. Zero fillers. Zero substitutes. Zero exceptions.

ISOLATE VS CONCENTRATE AND WHY IT MATTERS.

A study by the Journal of Clinical Endocrinology and Metabolism discovered that average testosterone levels in American men have been substantially decreasing since 1988. More troubling still is that the reasons for this decline are unclear. You see, low testosterone levels aren’t your fault. No matter how well you eat or how hard you workout, you still need a little extra help.

AND THE TASTE IS
OUT OF THIS WORLD.

“Unbelievable”, “outstanding”, and “extraordinary” aren’t words that are usually used to describe a protein supplement, especially one as pure as Iso-Smooth™. But then again, Iso-Smooth™ is no ordinary protein. With over 25 years of combined experience, it’s safe to say the Blue Star Nutraceuticals R&D team knows a thing or two about making great flavors. That’s why the brand Iso-Smooth™ flavors aren’t just good – they’re “unbelievable”, “outstanding”, “extraordinary”, and now, award-winning.

IT’S ALL IN A SINGLE SERVING.

THE PUREST PROTEIN ON THE MARKET.

That’s not just a claim, it’s a fact. The whey protein isolate in Iso-Smooth™ comes from biPro®, a trademarked whey protein isolate with an astonishing purity of 97.6%. Make no mistake, this is the single purest protein commercially available in the world today and one of only a handful that can scientifically claim to be free of sugar, lactose, cholesterol, and fat.

In most cases, fitting 30 grams of pure protein into a single serving would require drastically increasing the serving size. But not with Iso-Smooth™. The biPro® whey protein isolate is Iso-Smooth™ is so pure that you get everything you need in one, delicious, high-protein, low-calorie serving.

Finally in Stock

Found this product years ago and the quality can be tasted right away...Just hard because it is so good and the secret is out...means it can have long gaps of keeping it available!

Vanilla has a great taste and blends well, only thing I would say is the amount of calorie in total is a bit low compared to others especially for those bulking, but gets the job done, pretty impressed with its ability to dissolve making the shake not thin and I add two scoops

Best Protein on the market

I was reluctant to try Iso-Smooth because there are a lot of good protein shakes out there, some a bit cheaper, but Iso-Smooth outstanding in every way. Taste, mixing and of course all the numbers are the best out there. I'm a convert!!

Awesome

So far the best protein I’ve had. I mix it with almond milk and it has a better taste than mixing with water. I am still on my first can so I will wait to see what the results are. So far I’m liking it.
