Performax Labs IsoWheyMax: A More Powerful Whey Protein Isolate


The 2021 Performax Labs re-charge continues, with incredible new formulas hitting us left and right from their pre workouts (HyperMax and VasoMax) to weight loss (OxyMax). But now it’s time to get back to the basics, with protein.

However, this protein powder isn’t so basic, since it’s bolstered by Velositol and a potent protein digestive enzyme blend. And even more unique, there’s no Ace-K in the sweetening blend and the thickener is cellulose gum, so there’s no xanthan gum or guar gum, making a powerfully clean protein powder!

Performax Labs IsoWheyMax

Performax Labs IsoWheyMax is back in bold new labeling, with the same incredibly powerful, protein-enhanced formula with a unique thickener strategy!

IsoWheyMax from Performax Labs: More muscle protein synthesis

We’re talking about Performax Labs IsoWheyMax, a pure whey protein isolate that does more than the average protein powder. With the inclusion of Velositol and added digestive enzymes, you can expect to get more out of your shake compared to the standard whey isolate powder.

It’s all about protein

Research is mounting that high-protein diets are the key to health, strength, and good body composition.[1-5] The quantity and bioavailability of the protein we eat is a big part what determines our body’s rate of muscle synthesis,[3] and the thermogenic effect of protein, which is much larger than that of either carbs or fats, goes a long way towards us maintain and achieve a healthy weight.[3]

With that in mind, protein supplements are something that we should all consider adding to our dietary regimen. And Performax Labs makes a fantastic argument that IsoWheyMax is the best option to do that. We dig into the science behind these ingredients below, but first, check PricePlow’s deals and Performax Labs news alerts:

IsoWheyMax Macros

Performax Labs IsoWheyMax Ingredients

Yes, the WPI-90, Velositol, and digestive enzymes are incredible… but also notice what’s not in here: there’s no ace-K, no xanthan gum, and no guar gum! This is truly a unique protein.

  • Protein: 24g

  • Fat: 0.5g

  • Carbohydrate: 3g

    • Sugars: 1g

Here’s how they made it happen:

IsoWheyMax Ingredients

A single 30 gram scoop of IsoWheyMax yields the following:

  • Pure Isolate Protein – 26.5 grams (~88% of product weight)

    Whey protein is an excellent form of protein: it’s highly bioavailable,[6] fast-acting, and highly insulinogenic, which in the context of recovery from exercise is a very good thing. Compared to plant-derived protein supplements, whey is significantly higher in essential amino acids, the ones which our body cannot synthesize on its own, and must get from food.[7] Research indicates that whey supplements, when combined with a nutrient-dense, high-protein diet of whole foods, further improve body composition and strength in both men and women.[8-11]

    But what does whey protein isolate mean?


    Gone are the pure blue and black tubs, but we still have an incredible profile

    With whey protein isolate, the whey fraction of milk has been run through additional filtration after separation in order to remove as much of the residual fats and sugars as possible. In the case of IsoWheyMax, we get a whey protein isolate that’s about 90% protein by weight.[12] The result of this purification is that the supplement can be used flexibly — whether you are cutting carbs or cutting fat, this protein is pure enough that you can easily fit it into your macros.

    Long story short: a good whey protein, so long as you don’t have any dairy sensitivities, is an easy, no-brainer way to move your macros towards the higher end of the protein spectrum, which will yield many benefits for your physical health. And if you have some dairy sensitivity, whey protein isolate is the way to go (although those who are extremely lactose intolerant will probably want to continue to stay away from dairy).

  • Velositol (Chromium/Amylopectin Complex) – 2000mg

    It makes perfect sense to throw Velositol into a high-end protein powder, since Velositol is designed to increase protein utilization and muscle synthesis. Developed and patented by Nutrition21, Velositol is a chromium complex combined with amylopectin, a starch that modulates the insulin response and boosts the synthesis of muscle protein when taken with dietary protein.[13]


    Made by Nutrition 21, the experts in Chromium and Insulin management, Velositol can boost Muscle Protein Synthesis by using chromium and a ‘tickle’ of insulin-spike from amylopectin!

    A 2017 study comparing Velositol+whey protein to whey protein alone found that the Velositol+whey group had significantly increased muscle synthesis after a single dose taken immediately after a workout.[14] The interesting thing to note about this study is that it used very small doses of whey protein, nothing close to the 25 grams you get in a scoop of IsoWheyMax.

    Although the impact of Velositol on muscle synthesis when is disproportionately bigger when combined with lower doses of protein,[15] it does increase muscle synthesis at larger doses of protein as well.[15] Velositol have higher levels musclin, a myokine that’s released during exercise, and initiates hypertrophic muscle synthesis.[16]

    A recent double-blind, placebo-controlled study showed that Velositol, when combined with just 15 gram doses of whey, increased subjects’ maximum squat reps, vertical jump power, and vertical jump height.[17,18]

    Learn a bit about Velositol from Nutrition21’s R&D Director

    In episode #055 of the PricePlow Podcast with Nutrition21’s R&D Director Sara Ojalvo Perez, we get a quick sound bite that perfectly explains how Velositol works. Listen to it at the 16:38 timestamp:

    Note that the amylopectin in Velositol provides the majority of the carbohydrate content in IsoWheyMax, showing how clean this protein is – Performax had to add it to get that post workout insulin spike going!

    Velositol Squat Performance

    The velositol group had significantly better squat performance, and over time they out-performed both other groups![18]

    More about the chromium itself

    The chromium inside helps regulate the insulin response to rising blood glucose levels,[19-21] and chromium picolinate in particular (which is used in this supplement) has been shown to improve blood sugar and insulin sensitivity, especially in pre-diabetic or insulin-resistant people.[22,23]

    With this in mind, we shouldn’t be surprised to learn that people who supplement with chromium have a smaller chance of developing type 2 diabetes,[24] whereas people with chromium deficiencies are at a significantly higher risk for the so-called “metabolic syndrome.”[25] Chromium is also good at defatting tissues where fat doesn’t belong,[26] such as the liver in people with “Non-Alcoholic Fatty Liver Disease” (NAFLD), a common occurrence in the metabolic syndrome.

  • DigestivMax (Papain & Protease) – 100 mg

    Performax Labs IsoWheyMax

    New Label, same incredible whey protein isolate formula

    Protease is the “standard” protein digesting enzyme, which basically improves the digestion and absorption of protein, thus making it more bioavailable. In terms of sports nutrition supplements like IsoWheyMax, the use of proteases has been shown to help minimize damage and soreness in the muscles after hard exercise, and improve recovery.[27,28]

    Papain gets its name from the papaya fruit, which is used in tropical cuisines to help cook meat. It has a wild variety of uses, ranging from whitening one’s teeth[29] to spoofing drug tests,[30] but the one we’re concerned with is assisting the digestion of protein, which earned it the name papaya proteinase I.[31] Papain is particularly effective for people with certain types of ulcers.[31]

    With the DigestivMax blend, we get a bit more than your average protease-based supplement… and certainly get more than the average whey protein isolate shakes that generally don’t include any digestive enzymes at all!

  • Other Ingredients: Consider what’s not inside

    IsoWheyMax is sweetened with sucralose (no Ace-K!) and thickened with cellulose gum, which is a unique profile that contains no guar gum and no xanthan gum. While this is slightly less thick than shakes with gobs of guar gum, it’s a boon to those with sensitivities to these ingredients – which are usually everywhere in protein powders!

    As for calcium, phosphorus, magnesium, sodium, and potassium — these minerals are listed because they’ve been provided by the above ingredients themselves – namely the whey isolate. These minerals are great to have in any supplement that’s intended to support physical performance and recovery, since they’re lost in sweat and consumed in metabolic processes.

    Performax Labs IsoWheyMax Benefits

    This is how you build a whey protein isolate that differentiates itself and betters human performance

    For example, sodium, despite its bad (and generally false) reputation, is needed in adequate quantities for muscle contraction to occur.[32] Lacking adequate sodium will lead to subpar performance and recovery,[33] so if you feel like your levels strength and endurance are lower than usual, increasing your sodium intake is one of the first easy fixes you can try.

Flavors available

Performax Labs brought whey protein isolate up a notch with these flavors:

Performax Labs IsoWheyMax Chocolate

The new labels launched in 2021 look fantastic

    It’s all about high-protein diets and avoiding toxic oils

    Those of you who have been in the health and nutrition world for a few years will be familiar with the macro wars — the endless controversy over whether human nutrition should be “low carb” or “low fat.”

    The macro wars raged for decades with no clear resolution — but what we’re seeing in the industry today is the emergence of a broad consensus that low-fat or low-carb diets can both be effective, so long as they are high in protein (and low in the unhealthy fats, such as the omega-6-rich “vegetable oils”).

    Performax Labs makes a case for a best-in-show whey protein isolate

    We love and encourage high-protein meals, but once in a while, the sweet tooth kicks in. Don’t succumb to it with candy – treat it with protein. And the cleanest way to do that — without affecting either side of the carb or fat equation much — is with a whey protein isolate shake. Thanks to the inclusion of Velositol, Performax Labs makes an argument for one of the most powerful WPI shakes on the market with IsoWheyMax.
