Contrary to popular belief, not all proteins are created equal, and that is certainly the case with Protizyme. Due to its unique ultra-microfiltration and digestive enzyme coating processes, Protizyme delivers the highest bioavailability of protein per scoop than any other product on the market. With six delicious flavors to choose from, Protizyme’s incredible taste will make you wonder whether it is protein or dessert.*


Protein is an essential part of every balanced nutrition program. Not only is protein necessary for building muscle, it also helps satiate appetite and provides important nutrients for all cellular processes within the body.*

Using the highest quality proteins that have been ultra-micro-filtrated, Protizyme further enhances the absorption kinetics by spraying the protein particles with specific enzymes, making it easier to digest. To further enhance the nutrient profile, 24 essential vitamins and minerals have been added along with our powerful T.A.G. (trans alanyl glutamine) to improve recovery and absorption. With less bloat, easy mixability and fast digestion, you can utilize Protizyme anytime of the day, as well as before and after your workouts.*

What is so good about our filtration system, and why is it better?

Our filtration process is specifically chosen to preserve the natural protein structure of the protein and immunoglobulins. It does not denature or alter the protein structures like acid or hydrolysis treatment. Our protein filtration system allows us to successfully derive a 85% protein concentrate that exhibits the nutritional macro-nutrient profile of an Isolate, yet we still preserve the protein structure and the immunoglobulin peptides.*


Where is the whey sourced from?

All of our whey comes from the United States of America.


Why is there Lactase in the Protizyme if its lactose free?

We include Lactase in our proprietary enzyme complex due many of our consumers choosing to mix Protizyme in milk. We have to account for an enzyme to assist with this breakdown of lactose sugar.*


Can I cook with Protizyme?

Yes, but do not exceed 350 degrees, and do not cook for extensive periods of time.


If I have allergies toward any type of nuts, can I use Protizyme?

Yes and no. You can use all Protizyme flavors with the exception of Peanut Butter Cookie.


What makes it so expensive?

We use a highly expensive microfiltration process that yields a unique 85% Whey Concentrate with the Immuglobulin peptides preserved. The protein is perfectly preserved in this process, making for a protein that absorbs digests and absorbs with greater ease and efficiency than all other proteins. Protizyme is also available in a range of delicious flavors that are sure to blow away competing supplement brands in taste. The better question is, “why are all of the other proteins on the market so cheap?!”*


What do the percentages mean in the ingredient profile for the immunoglobulins?

These percentages are the percentages of the different immunoglobulin peptides composed in Protizyme protein.*


Why is the cholesterol so high?

The cholesterol is the natural occurring cholesterol level remaining after microfiltration process to preserve the immunoglobulin protein peptides which are critical growth factors in Protizyme. This cholesterol is needed to preserve these critical protein peptide structures, as well as aid in the formation of healthy hormone production.*


Why do we use sucralose instead of something natural like Stevia?

Sucralose was used as a sweetener due to its high impact sweetness factor. This allows us to use significantly less of this sweetener than other comparable sweeteners. Metabolic Nutrition also develops it own flavor system for its products so we were able to use significantly less Sucralose than other companies and still derive a very “natural” taste characteristic. Based on this, we use 1/1000 less sweetener than other comparable formulas. As compared to other natural sweeteners, such as Stevia, we would have had to use upwards of 10,000 times the amount of Stevia to produce the same sweetness level. That would have come at a cost in terms of price of product (higher), bad or chemical off notes, and significant digestive issues (especially in our bariatric patients).*


Are the cows grass fed and growth hormone free?

Yes. All of the cows that source our whey are grass fed and are growth hormone free.


What are the peptide benefits of Immunoglobulins?

These ultra small peptides are usually referred to the “magic” of Mother’s milk. They are the components of Mother’s milk that aid in boosting recovery rate, building of lean muscle mass, fortify your immune system, increase growth hormone levels, and aid in macro nutrient assimilation.*


What are Lecithin, Xanthan Gum, and Guar Gum used for?

These ingredients are used to help make sure Protizyme is well dissolved and consistent in flavor when mixed with either milk or water. These stabilizers help maintain a homogeneous blend of all the ingredients when mixed in water, thus keeping Protizyme the same from the 1st sip to the last.*


How is it ideal for bariatric patients?

Protizyme is ideal from Bariatric patients as it can be taken in as little as 6 ounces of water and still enable the patient to have ease in digestion and absorption. It also provides 33 percent of the recommended RDA for vitamins and minerals per scoop, which can greatly assist the diminished ability to absorb V/M from food. It also provides T.A.G. glutamine to help preserve muscle mass in the bariatric patients which is critical as they want their rapid weight loss to come from fat not muscle.*


What are the benefits of the digestive enzyme blend?

The digestive enzymes in Protizyme aid in the rapid and efficient digestibility and absorbability of the protein. This creates less work for the body so it can focus more on the utilization of the protein and allow it to enter the blood stream for rapid use by the body.*


Why is it 100% Whey?

Because whey protein has the highest PER ratio of absorbability.


Why am I not getting the same amount of scoops as servings per container stated?

When you scoop, you may actually be yielding a scoop weight of 35 – 40 grams as opposed to the label serving size of 35 grams. The scoop we provide is developed to provide the best average and consistent weight per scoop, but it is an approximation.*


Why does the grams of protein per serving change flavor to flavor?

Some flavors have a slight effect on protein inclusion, causing a minor protein difference from flavor to flavor.


Are the products Parve?

No. Whey protein comes from dairy, and even though it is not considered a dairy protein, we still do not consider it Parve certified.


Are the products kosher?



Do any products contain animal byproduct?

    This protien is fantastic! Great taste, smooth mix, no BLOAT. Filling for inbetween grab and go and great post workout. Ive tried the peanut butter cookie and its delish even mixed with just iced coffee alone! I look forward to trying the other flavors. Bloating has been a huge issue for me with protien and im sold on this stuff. Thanks for a great product that packs all my nutrient needs for weightloss, quick meal replacement and post workout recovery with the protein. I look forward to purchasing other flavors.

    Absolutely the best protein I’ve ever used, I’ve had no bloating and the taste is amazing. I’ve been using it for about 2 months and been seeing some amazing muscle growth and increased strength.

    I work at Nutrition Zone and Metabolic Nutrition is my go to brand for my own supplementation and is generally the one i recommend to my customers. I dont write reviews often but I just wanted to thank you guys at metabolic nutrition for making such great supplements. Protizyme tastes great, mixes well, is a source of Trans Alanyl Glutamine and has gotten nothing but positive responses to those who ive reccomended it to. Ive tried and use almost every supplement by you guys at M.N depending on my goals. If you ever need a test dummy for reviews on any supplement im your man!

    Absolutely the best protein I’ve used. great taste, mixes well, no digestive issues and great results for building mass and strength. I’ve been using ProtiZyme for four months now, recommended by my gym owner and I beleive we have connected with the best product for the money!!

  6. Rated 5 out of 5


    This protein is a must buy for anyone and everyone! Tastes delicious!!! I was a collegiate athlete and have used many proteins throughout my career. This is by far the best tasting protein, doesn’t cause digestive issues and mixes really well. My go shake for a replacement meal or post-workout is a scoop of the chocolate cake, a bit of chocolate almond milk, PB2 (powdered peanut butter), a handful of spinach and ice. Blend and viola…..Tastes like a chocolate milk shake, and you will stay full for hours. If you are serious about improving in the gym, this is a must.

    This is the best protein I have ever tried. I’ve tried several of the ‘popular’ brands that are recommended and they will never live up to Protizyme. Peanut butter cookie is amazing. No bloat or chalky taste.

Take one to two scoops any time you desire to add protein to your diet. Research has shown that consuming additional protein around your workouts enhances recovery, improves immune function, reduces overall body fat, and provides cellular energy that is crucial for health benefits.*
