At Core Nutritionals, a meal is well-balanced, nutritious, and most importantly delicious. Yet most "meal supplements" are full of filler carbohydrates, low-grade proteins, and chalky flavor mixtures that have little taste and even less nutrition. We would hate to see the "meals" these supplements are supposedly substituting.

Core MRP is a better solution - a true meal supplement, not a meal imposter. Grain-sourced carbohydrates, not fillers, and high glycemic carbohydrates. Rich protein sources from high-quality whey and casein, not bottom-of-the-barrel powders. Premium flavors, digestive enzymes, and vitamins and minerals from real whole foods, not whatever else was lying around. Everything your body needs in an instantized, easy-mixing, convenient, and delicious blend.

Carbohydrate Blend:

Before we dive in to understand the complexity of Core MRP, lets back up and first understand exactly what’s occurring when we consume carbohydrates on a daily basis – and in particular, when we consume around our workouts (peri-workout nutrition).

The consumption of carbohydrates, by its nature, results in an increase in the concentration of plasma glucose (or blood sugar) – and, in turn, insulin is released from the pancreas as a result. Insulin then initiates a number of signal transduction pathways related to both protein and glucose metabolism, with the upshot being increased glycolysis (the breakdown of glucose to ATP), glucose oxidation in response to greater glucose availability in the cell, and glycogen synthesis (the stuff that essentially makes muscles, “pop”). In other words, an entire host of both necessary and amazing things!

With that said, insulin does induce some negative effects, as well. This powerful hormone is responsible for a range of lipogenic (fat-creating) effects, including both adipocyte differentiation (turning what are known as pre-adipocytes into mature adipocytes, or fat cells), and proliferation (the expansion of cells). Insulin controls these processes by tightly regulating numerous signal transduction pathways, and is in fact one of the key hormones responsible for controlling how adipocytes function.

So, you have a hormone that, on the one hand, does a range of absolutely crucial things related to muscle and muscle cell metabolism, and on the other, does similarly crucial things related to fat and fat cell metabolism. How do we separate the good from the bad, then?

The easiest, most reliable way to ensure that these processes continue to work in favor of your body composition goals, is to very carefully and strategically select your carbohydrates sources. For us at Core, and specifically for Core MRP, this means choosing only low glycemic carbohydrates for inclusion in our everyday meal supplement.

Whole Grain Oats:

Low-glycemic carbohydrates are ones that elicit a smaller, “glycemic” or glucose-releasing response in the body; meaning they also induce less of an insulinemic response, as well. The result is that low glycemic carbohydrates, as research indicates, not only cause enhanced fat oxidation (the literal burning of fat) when compared to high GI carbs, but also spare muscle glycogen. This result is the best of both worlds: your metabolic engine stays engaged, and the substance that gives your muscles their fullness, glycogen, is spared.

It is for the reasons above that high-quality, low-glycemic carbohydrates are such a crucial component to an excellent meal supplement. Unfortunately, that is simply not the industry trend: even a cursory glance at most, “meal replacements” reveals a litany of high-glycemic, insulin-inducing carbohydrates that, while they have their place, are completely inappropriate to include in an all-day, everyday meal replacement.

Core MRP is not like the rest. We are setting a new standard with the product that started it all. We have chosen only high-quality whole grain oat flour to include as your carbohydrate source. Oats offer a wide variety of benefits aside from just providing carbohydrates for the body. Some of these include:

Oats contain considerable amounts of valuable nutrients such as proteins, starch, unsaturated fatty acids, and dietary fiber as soluble and insoluble fractions.
Oats contain high amounts of beta-glucan, a fiber that has been studied extensively for its benefits on aiding digestion and supporting the gut microbiome.
Oats also have been shown to aid in the control of certain heart-related conditions, such as high cholesterol.
We at Core have put a lot of time and effort into the formulation of our products, and Core MRP is not different. This allows you to remain confident that consuming Core MRP is not only allowing you to cost-effectively and conveniently meet your caloric goals for the day, but more importantly, that our product is not compromising your hard work or lifestyle.

Protein Blend:

If you have been following us for quite some time, we likely don’t need to explain just how and why adequate protein intake is fundamental to achieving your goals. With that said, there may be some confusion as to what specific kinds of protein are going to benefit your goals and why.

Like we did with carbohydrates above, let’s look into the specifics a little bit rather than just supplying a generic answer. We are anything but generic after all! The word “protein,” without any qualification, is perhaps the broadest term you can possibly use when speaking about biology – to the point where asking, “How much protein should I consume, and which kind?” renders itself useless. Considering proteins are more or less complex compositions of amino acids, and considering that amino acids have different functions, what we want to ask is something more specific like, “Which kinds of protein have the amino acid composition best suited to my goals, and when should I consume them?” A mouthful, but you get the point!

So, what does a “good” amino acid composition for a protein supplement look like? Well, while biologists would never use the term, “good”, they describe more robust proteins – one with amino acid profiles that can best facilitate tissue growth – as, “complete proteins.” These proteins contain high amounts of essential amino acids, are rapidly digestible, and support the available amino acid profile over a long period of time.

Simply put, and if we use the definition above, Core MRP has one of the most complete amino acid profiles available in any supplement. We have a included a blend of the most bioavailable and high-quality proteins to create a blend specifically catered to fuel your body’s need throughout an entire day, not to mention we have full transparency on our label too, so you know exactly how much of each protein you are getting.

Cold-processed undenatured whey protein concentrate: Whey protein concentrate is probably the most common form of whey protein you will find. However, how it is processed is where the benefit truly lies. This process of cold processed undenaturization preserves the molecular structure of the amino acid particles as well as the immune-boosting benefits that it contains. This undenatured protein is also a rich source of amino acids, including those needed for the synthesis of glutathione, which is an important antioxidant that can be depleted by stress (exercise stress included). This makes it a great foundation for your post-workout recovery nutrition.

Cross-flow microfiltered whey protein isolate: whey protein isolate is an extremely “clean” form of whey protein. It yields a higher amount of amino acids, half of which are from the essential amino acids (cannot be made by the body). Microfiltration eliminates a large majority of the fat and lactose from the whey, which makes it easily digestible and quickly absorbed into the body. This cross-flow process uses a highly intricate method to isolate the protein. It is not subjected to chemicals and is thus left in its most natural state.

Milk Protein Isolate:

Milk protein isolate is obtained through the partial removal of non-protein materials from skim milk (lactose and other minerals). What you are left with is a dry product that contains more than 90% protein by weight. This product contains both casein and whey proteins in their original proportions found in milk, without combining separately produced casein and whey proteins. It contains very little fat and lactose and also has a very high amino acid composition making it a perfect addition to this blend.

To both immediately increase the amino acid pool, and fuel your bodily processes (like protein synthesis) throughout the day, we’ve strategically included such a robust, multi-purpose blend using multiple forms of synergistic proteins that truly complement each other to positively impact your health and fitness.

The point of an excellent meal supplement is to cover all your bases, so you don’t have to. Core MRP in MJ with the ball with 5 seconds on the clock and The Bulls down by 1. Our multi-stage protein blend is ready to give you everything you need to maximize recovery, increase protein synthesis, and improve your health when you need it most. If your body needs it, Core MRP has it.

Whole Food Based Vitamins and Minerals:

There are a lot of great things about Core MRP already, but what really makes it stand out from other meal supplements on the market is the complete and well-roundedness of this product. Our sources of carbohydrates are more superior, our blend of protein is unmatched, and last but not least, our completely whole-food-based blend of micronutrients is second to none.

Listing each of our micronutrients in succession, along with all the benefits they pose to the human body, would require us to write a book – literally. We have included everything from A to Zinc in dosages needed that will truly make a difference. We have also added a specific and blend of key foods, like broccoli, kale, sweet potato, chlorella, and shiitake mushroom to name a few. This is the most complete meal supplement on the market.

In addition to our vitamin and mineral matrix, we have also included the digestive enzyme blend, DigeSEB™, comprised of five of the most clinically-researched, critical function enzymes available. We have chosen this blend for its powerful synergistic properties and abilities to help aid in the breakdown of milk proteins and sugars, support healthy carbohydrate and fat metabolism and breakdown, and assist in the metabolism of carbohydrates and starch.

Delicious tasting MRP

I have a difficult time eating more to grow and a difficult time digesting 50 grams of protein in one shot. I wanted to give Core Nutrionals MRP a try and I am glad I did. First the taste, when I was a kid I loved taking a large slice of pound cake and dumping it in my milk, the pound cake would quickly soak up the milk and then for me it was amazing to eat, however the special treat was the milk with the vanilla flavor of the pound cake and pieces of pound cake in the milk made drinking it so much better, that is exactly what this is. This is great in the morning, afternoon, evening, after a workout or a late night snack and I only use Sugar Free Almond Milk, I have not tried this with water and do not intend to. When this is done I will be buying another tub for sure and even consider trying a different flavor. One last thing, I feel no stomach pain at all, I am learning my body can only digest 25 to 35 grams tops which is cool with me, as this is exactly 25grams of protein, as well as a whole slew of vitamins.
