Product Overview

What do you look for in a protein supplement? More importantly, what should you look for? Let’s be honest: in 2020, taste is paramount to the experience. Amazing taste was our priority for the reformulation of Core PRO – and we succeeded beyond our wildest dreams, if we say so ourselves.

But this is Core Nutritionals, meaning that function must always match taste and form. Core PRO is no different. While the protein blend in Core PRO was always industry-leading, we have made it even better. Our blend of whey concentrate, whey isolate, and milk protein isolate delivers smooth texture, fast and slow-digesting proteins, and a complete amino acid profile that suits your needs. In other words, have perfected the marriage of TASTE AND PERFORMANCE, and the result is Core PRO.

Core PRO is a sustained release protein formula, specifically designed to keep you fueled with the right growth/recovery agents over extended periods of time.* This innovative blend provides the perfect arrangement of both fast-uptake and sustained-release proteins, from superior cold-processed whey proteins and micellar casein-rich milk protein sources. This strong synergistic blend helps promote optimal growth and recovery by providing the vital building blocks your body needs, exactly when you need them most.* Our superior protein blend contains a generous array of BCAAs (branched-chain amino acids) in their naturally-occurring biological ratios, to delay fatigue and expedite your recovery.*

The benefits don’t stop there. To make this the most effective recovery formula available, we’ve enhanced it with a powerful digestive enzyme blend, including protein-digesting proteases, to improve absorption and accelerate nutrient uptake.* The beneficial fatty acids from MCTs (medium chain triglycerides) in Core PRO help preserve lean mass while unleashing your body’s natural metabolic potential.* And unlike some formulas, you never have to worry about taking it at the wrong time. Staying fueled all day or overnight never tasted so good!

I have rated the product a 6 for a few reasons. The first reason being the protein blend. I for one, prefer protein blends however the blend starts off with a cheaper whey protein concentrate. Core Nutritionals as a whole states that they use the best ingredients and to me, concentrate is just a cheap source of protein. The second reason being the company also states they use no proprietary blends however their protein, being Core Pro, is a giant proprietary blend in which they do not state the amounts of each source of protein used. Lastly, the flavor. Peanut Butter ice cream is a false name for how this product tastes, the flavor should be called Peanut Flour because thats all it tastes like... you have no flavoring whatsoever of any ice cream and it just tastes like watered down peanut butter.

Great ingredient profile and plus it has low carbs and low fat. Added healthy fats and digestive aids makes a great. Plenty of servings per tub also. The cinnamon roll flavor isn't strong at all compared to Cellucor's protein. It taste kind of bland but not bad at all.

Ok taste. Not as sweet as I was expecting but a decent mix. Bought because my wife likes this brand and her new gym has recipes that uses this to account for macros. Getting the vanilla flavor next so hope it is at least as good as chocolate.

This stuff is AMAZING!!! I've been a big fan and using Core Nutritionals products for the past 5 years now. I add a couple scoops of cinnamon roll to my coffee in the morning topped off with cashew almond milk. If you are a big fan of those flavored coffees, but want to stay true to your nutrition goals this is a MUST try! Check out this awesome brand. Everything clearly stated on the labels with no fillers.

This is a great product, the only thing i dont like is that it has fats and carbs in it. Which depends on what im doing at the time or if i have the extra space in my macros to fit the adding calories. The fats come from medium chain triglycerides (same as coconut oil) so you cant hate on the type of fat, just the fact there is fats. Other than that its a geat product, im very picky on my protien and i use this when it fits. Peanut butter ice cream taste like melted ice cream.

I recently got a sample of a new flavor Cookies & Cream. I must say this was excellent. Like so many proteins out there, flavor become very important. The one serving contained 25g of protein. It mixed very will in a shaker cup with 8 oz. of water. No clumps. Was not harsh on the stomach.

Couldn't get it to mix very well. I only had a sample of each flavor, but I didn't really care for them. Chocolate delight tasted pretty good and mixed the best. Peanut Butter Ice Cream tasted like homemade ice cream but left huge chunks floating around. And Cinnamon Roll was virtually flavorless and had little gritty things at the bottom.

Got a sample of the PB Ice Cream and it tasted just like that. Taste was on point and rivals Cellucor's PB Marsh. I had it in water and tasted great, can only imagine what it would taste like in almond milk, or as a sludge. One of the best tasting proteins I've had

One of the best blend protein powders on the market. Taste is great and coming from this company you know that the amount of protein claimed on the label is the actual amount contained within the product. This is a great addition to any supplement stack if you need more protein throughout the day.

After trying to buy a shirt for Core for Christmas and they just happened to be out of my size, Core sent me a sample along with a bracelet as an apology. Few supplement companies in the industry would go through this trouble to help out one customer. I tried the sample and LOVED it! Not only did it taste amazing but the ingredient profile is just as great. Great quality protein and the added MCTs make it even better. Core doesn't hide anything on their labels which I also love, no sneaky proprietary blends that hide what's really used. The price may be a little higher than other companies but if you have it, the taste quality, ingredients, and customer service that come with it make it well worth the money. Can't wait to use more Core Nutritionals products in the future.
