GFUW The Better Protein

The Grass-Fed Ultra Whey Advantage

Whey Protein to Build Muscle

GFUW For Muscle Growth

You work hard in the gym. Now maximize your results with a protein scientifically designed to maximize MPS and build muscle mass, increase strength and power.

Your muscle is either building – something called Muscle Protein Synthesis (MPS), or it is breaking down. Muscle Protein Synthesis triggering is most stimulated by eating rapidly digested foods that are high in branched chain amino acids. No protein on the planet has shown better MPS than whey protein. Combined with resistance exercise, adding an ultra-premium whey protein to your regimen will increase muscle growth far more than any other protein.

Very fast absorbing, 100% grass-fed Whey Protein Isolate (WPI) produces the fastest spike in leucine blood levels called the amino acid reference ratio (AARR). This high AARR correlates with Muscle Protein Synthesis stimulation. A second higher spike in leucine levels is seen with 100% grass-fed Whey Protein Concentrate (WPC). Combining WPI and WPC produces a great blend to maximize leucine levels over a larger window of absorption*.

GFUW for Recovery

Your intense workouts are all about building a better body. To take advantage of every workout, you need to recover properly in between. No one wants to be limited in their training from the previous day’s workouts.

All types of exercise will directly cause muscle to breakdown. This is called exercise induced muscle damage (EIMD). Different types of exercise cause damage to different types of muscle proteins and these proteins need to be repaired. This is called recovery and is a vital part in being able to perform at your highest level.

The faster a protein is absorbed, the quicker the repair process in the muscle will begin.

This is why a protein powder after exercise is far more advantageous than consuming a regular meal. The protein’s in whey are faster absorbed and better utilized in repairing and rebuilding muscle than any other protein studied**.

Yes, better than egg, better than soy, better than beef, chicken or fish, and far better than casein**.

Whey Protein Improves Recovery
Whey Protein for a Healthy Lifestyle

GFUW for the Healthy Lifestyle

Let’s face it: we not only want to be as good as we can athletically, we want to be as healthy as we can be. Many athletes are inhibited by being “Fit Sick“. They look great on the outside but their micronutrients, lipids, and immunity may borderline or deficient.

Besides building muscle, whey can be very good for your overall health. The health benefits attributed to consuming whey protein were first written about by Hippocrates. The benefits of whey (at that time called the serum) have been known since 400 B.C. In the last 30 years, researchers have uncovered many of the scientific health benefits of whey.

Besides understanding the musculo-skeletal benefits of whey, scientists have researched the following health benefits*:

  • Immunity and Antioxidant Support*
  • Lipid Support*
  • Liver Support*
  • Bone Support*
  • Heart Support*

GFUW Ingredients & Usage

How to get the most out of your supplements


You have to consume a certain amount of protein daily. Using GFUW as a protein supplement to your daily nutrition can help you achieve your goals. Each serving of Grass Fed Ultra Whey will provide 27 grams of rapidly absorbed protein.

GFUW is instantized so you can easily mix it in only 4-5 ounces of water. But because it is instantized you can easily mix it into yogurt, peanut butter and almond butter.

Start your day with 1 scoop of Grass Fed Ultra Whey prior to breakfast. That’s right, take it right after you get out of bed. Because it is non-bloating you can still have a breakfast if you choose but now you will have a much better nutritional profile than a typical low protein breakfast.

It will also kick MPS into gear to start your day.

Your next serving of GFUW is perfect after you work out. Consuming an ultra-premium protein powder following your work out will further stimulate muscle protein synthesis, as well as support thermogenesis and body composition.

For most people on a hypocaloric diet, two servings of GFUW a day, along with an appropriate amount of lean protein at dinner, will be the core to a successful fat loss program.


Grass-Fed Ultra Whey is not for use by those with pre-existing medical conditions; those taking any medications; those under the age of 18, or women who are contemplating pregnancy, pregnant or nursing. Always consult your physician prior to starting a new supplement and exercise regime. Keep out of reach of children and pets.

Your Top Questions, Answered

Still Have Questions? We’re Here to Help.

  • What is the best way to mix GFUW?

    To maximize the GFUW flavor profile, mix one scoop in 5-6 ounces of water. GFUW is so refined that you can also mix it directly into yogurt. Though you can mix it in milk or almond milk, there is really no need to the added calories, fat or carbs.

  • Why do you use 100% grass-fed in-pasture cows as the source for GFUW whey?

    Grass fed cows milk has a higher content of CLA, Omega-3 and Vitamins than grain fed cows milk.

  • Can College, Olympic, and Professional Athletes use GFUW?

    Yes, GFUW is tested, verified and certified to be banned substance free by Informed Sport. Informed Sport certification is an extra step to insure quality, safety, and efficacy (QSE).

  • Why do you use only Whey Isolate and Concentrate as opposed to additional protein types?

    First, Whey has the highest bioavailability of any protein on the planet. It is higher than egg, meat, fowl, and fish by 20-40%. And even higher when compared to casein, milk isolate, and milk concentrate. This means more availability for feeding your muscles. The purpose of a protein powder is to conveniently add protein to your system without eating a meal. Why wouldn’t you want it to be the best possible?

    Second, by adding additional proteins to a formula, supplement companies are able to take advantage of FDA guidelines and dumb down their formulas and minimize how much of the expensive ingredients they put in.

  • Is Grass-Fed Ultra Whey produced in cGMP facility?

    The FDA requires manufacturers to follow Good Manufacturing Practices. We take it a step further. Our facilities are certified by independent testing labs to meet or exceed Good Manufacturing Practices.

Best Flavor & Results

We've been using this as a family. It has the best flavor and both my husband and son say it's given them proven results.



The Best.

Over the years, I've tried several brands of protein, from some of the best-known manufacturers. I always focus on protein content per serving, as well as purity of the product. I started buying the Dioxyme protein at my local nutrition store based on the owner's recommendation. I liked the flavor, consistency and formula so much, that when the nutrition store closed I searched for the product online. I'm impressed with the high concentration of protein isolate/concentrate, complimented by BCAA. The Dioxyme formula is nutritious and satisfying. My favorite nutritional supplement is a daily protein shake made with Dioxyme Ultra Whey blended with fresh fruit. I make mine with skim milk, so it tastes like a milk shake.

Miss the old formula

This new Ultra Whey formula is good don't get me wrong, 27g per scoop is great. But a 38g total scoop is pretty huge, that means adding more water and I sometimes have a hard time to get the scoops to shake when I put them in a shaker bottle. Miss the original, but thanks for some good products.


I have tried many protein powders - this is by far the best!!!
