What is Whey Protein Isolate?

Whey can be split into two distinct types, isolate protein and concentrate protein. The main difference is that isolate protein is leaner and has fewer calories.

Isolate protein undergoes intense processing which essentially makes it a purer form of protein, usually containing a total of more than 90% proteins.

Concentrate undergoes less processing and is, therefore, a less refined protein powder, with some carbohydrates and fats remaining in the formula.

Isolate protein is typically more expensive than concentrate, plus, it's better suited for athletes trying to maintain low-carb or low-fat diets. Isolate is also naturally lower in lactose, which makes it perfect for anyone sensitive to dairy.

You can get the same nutritional benefits from Whey Protein Concentrate, however, if you're looking to lose weight or if have any issues with your digestion or gut health, we highly recommend paying extra for a Whey Protein Isolate supplement, like Muscle Nation Protein.

What is DigeZyme®️?

We've got many digestive enzymes in our body - in our saliva, our pancreas and even in the lining of our intestine. These little molecules are incredibly important as they work to break down our food during digestion, and without them, our digestive system would completely fail as they're imperative for nutrient absorption.

Most of the foods we consume contain high levels of enzymes, however, studies show that as soon as heat as applied to most fresh vegetables and meat, the enzymes begin to break down and disappear. So, most of the foods we're consuming have little-to-no enzymes at all.

DigeZyme®️ is a unique blend of digestive enzymes (amylase, lactase, cellulase, lipase and protease) each with their benefits and purposes. Digestive Enzymes are added to nutritional supplements to help speed up digestion and help the gut to break down all sorts of things in our food such as lactose, starch, fibre and fat into small particles. This helps the gut to digest food much more easily and smoothly, plus, it also improves the absorption of nutrients, whilst reducing any stomach discomfort or bloating.

Studies have found that Digestive enzymes help the body to absorb protein particularly well. The body has to work a lot harder to separate protein molecules into their amino acids, so it can use them efficiently. Digestive Enzymes provide the right environment for optimum protein absorption, which will in turn boost muscle protein synthesis, helping your muscles to repair quicker and grow bigger, compared to those who take protein supplements without them.

On top of this, if you have a poor diet or suffer from poor gut health, you may be at risk of toxic build-up in your body which can lead to further digestion issues, poor immune system and low energy levels. If this sounds like you, we highly recommend trying Muscle Nation Protein today.

What is Velositol®️?

Muscle Nation Protein contains Velositol®️ a patented ingredient, used to accelerate and boost muscle protein synthesis, encourage lean muscle tissue growth and faster recovery post-workout. Velositol®️ is completely flavourless and is commonly added to sports nutrition supplements. It's a non-stimulant and proven-safe, plus, it can be stacked with other supplements without any risks.
