Your workout is the jungle. Whey isolate is the lion – its King.

Core ISO is, simply put, the pinnacle. Our protein’s quality, level of purity, and most importantly, gourmet taste, make drinking a shake your favorite and most effective part of your training day!

  • 1 scoop per serving.
  • 21 servings per container.
  • Purest protein available.

If the post-workout environment were a jungle, whey protein isolate (WPI) would be the lion – its king. Newer proteins enter into the market, receive fanfare and applause, and then inevitably fall out of favor. WPI, however, is the U.S. Dollar, Greenwich Mean Time, or Michael Jordan’s dunking prowess: it is the reference standard against which everything else is measured. The success or efficacy of all other proteins is gauged relative to what the one true king, WPI, has previously done.

So, given WPI’s long-standing Elvis status, there is simply no way it could be improved on. Right? Wrong. Amino-filled and/or spiked, low quality, low purity WPI formulas still run rampant on the market – robbing consumers of what they should be receiving, and exchanging the king for a jester.

That has never been Core’s approach, and it never will be. With Core ISO, we have developed the purest, highest-quality, least-adulterated WPI product on the market. We have taken the highest purity, non-instantiated, non-soy, non-GMO whey protein isolate available, and essentially added nothing to it: we have added no sugars, making it the perfect versatile protein; and we have added no artificial colors, meaning you can feel good about drinking it.

Did we mention we use natural flavoring? And Oh. My. Goodness, what flavoring it is! While the bitterness of WPI overcomes most brand’s offering, and results in a dull, palette-killing powder you need to choke down, Core ISO tastes like a gourmet pastry chef set up shop, on your tongue, and started making soufflés like nobody’s business.

Core ISO is, simply put, the pinnacle. Our protein’s quality and level of purity transcends it to the level of being a necessity; a part of your supplement and training setup that is simply assumed to be there, because it must be there. So, if you are already taking or planning to use protein, why not use the version of the standard that rises above the rest?

Physiological Properties and Effects:

Whey Protein Isolate (WPI):

Whey protein isolate (WPI) was said above to be the king of proteins, but what does that mean? Why are proteins in general necessary, and more importantly, what are their functions as a workout supplement?

When you vigorously train or exert yourself, a process called protein degradation (the breakdown of muscle protein) begins so that the body can fuel itself. Think of this like shutting off your engine, in order to fuel your car (muscle protein breakdown). As this entire process plays out, the available pool of amino acids in skeletal muscle depletes, as they too, are drawn in and broken down in the natural, catabolic process during exercise training.

While this situation is quite adequate during a training session, it’s precisely the opposite of what we want afterwards. At that point, we want the available pool of amino acids to increase, protein degradation to slow or stop, and muscle protein synthesis to increase. The famous, “anabolic window” is occurring during this time period, so a protein powder that is rapidly digested, and that rapidly increases the available pool of amino acids, is needed to ensure that the switch between protein degradation to synthesis is as beneficial as possible. After this anabolic window passes, or before it even begins, we also want to ensure that the available pool of amino acids is high enough for your body’s constant growth cycle.

At this period, protein quality is also vital. Human skeletal muscle makes the most use out of a few, particular amino acids, and so a quality protein needs to have an amino acid profile that is optimal for this context. An, “optimal amino acid profile” contains a high amount of BCAAs, and in particular leucine, to counteract the rate of leucine oxidation that occurs as the fractional rate of protein synthesis decreases, and the rate of muscle protein degradation increases.

We chose whey protein isolate as the only protein in Core ISO for precisely these reasons. An excess amount in the available pool of amino acids (especially leucine) is called hyperaminoacidaemia, or specifically to leucine, leucinaemia. After a period of intense exercise training, we want this condition to arise immediately, peak after approximately one hour, and then be sustained until another protein source can be ingested. The evidence is quite clear that whey protein isolate not only achieves this, but also may achieve it at a greater potency as compared to other protein sources.

In a non-double blind study, two groups of healthy men received either micellar casein, or whey protein isolate, after a sustained bout of exercise training. Post-training, muscle protein synthesis, essential amino acid, and leucine levels were tested and compared. The study authors conclude that, “the ingestion of isolated whey protein supports greater rates of MPS than micellar casein both at rest and after resistance exercise in healthy elderly men. This result is probably related to a greater hyperaminoacidaemia or leucinaemia with whey ingestion.”

As we said above, it is critical for a protein’s effectiveness that it contain a robust amino acid profile, one that is particular high in leucine. This is because leucine is both the most physiologically important amino acid, with respect to muscle mass, and the most extensively studied. Data on leucine demonstrate this amino acid plays critical roles in stimulating skeletal muscle protein synthesis, and ribosomal biogenesis and assembly (the literal building of muscle tissue), along with playing a lesser role in insulin signaling and gluconeogenic processes. As a result of these diverse roles, leucine has been demonstrated to significantly stimulate skeletal muscle protein synthesis, and attenuate protein degradation, as in the above study, by both insulin-mediated and non-insulin mediated mechanisms.

In order to counteract a negative intramuscular protein balance, a number of things need to occur – mostly, a rapid increase in the availability of amino acids. There is strong evidence to suggest that, amongst protein supplement, WPI best achieves this feat.

Great value, good suds, good quality, good for the environment
Color: 5 Pack
Goodness I love these. I moved within the last several months, and my new town and state is not as on top of recycling as my old state was. This isnt a super huge problem, but it meant I had to start finding ways to reduce my refuse. Less bottles. So naturally I switched to bar soap. I also knew I wanted to stop using those plastic net poofs. I didnt have easy access to a washer, and I hate laundry anyway.. so washcloths arent a huge part of my life. What was a girl to do? Buy these. Thats what everyone should do. They hang nice. My soap dries. It exfoliates amazingly without being too rough. I tried another brand before this and it was *blows raspberry* 💩. Fell apart super easy, didnt suds up well.. just no. But this one I love. The soap I bought fit just fine, but took up the whole net. I didnt like that. It didnt dry as well or suds up at all. So I started cutting my soap in half and now it works GREAT. Warning - its not good on your private bits. Itll scratch you the heck up. You shouldnt be using anything on your private bits other than soap and your hand anyway. I also recommend harder bars of soap. Super soft super lotion infused bars dont seem to hold up as well. If youre trying to reduce your plastic waste and like feeling amazingly exfoliated, this is for you.

This handy little tool holds my soap and exfoliates my skin gently.
Color: 5 Pack
I bought this as a bag for my new shampoo bar so it'll last longer. This bag generates a nice lather, hangs off my shower caddy, and allows the bar to dry between uses. Makes shampoo bars much more convenient. The texture of the pouch remains scratchy after 3 or 4 uses so far but it produces a good amount of lather in combination with my bar soap. Hoping it softens up with use. Very good for exfoliating! The bag does have a canvas scent to it, but once you add water and lather up the soap inside it disappears. I love this bag. We always have a bunch of soap pieces in a basket on our tub, and now we can use them till there’s nothing left! My husband's biggest complaint when convincing him to switch to bar soaps with me was that they are so slippery in the shower and difficult to use. This thing is the ANSWER! It's the perfect sudsy, exfoliating grip for bar soaps that is still eco friendly - plus, the string is great for hanging on the shower head after!

An Eco-Friendly Solution for a Zero Waste Bathroom
Color: 5 Pack
I recently purchased the E-Know Soap Bag 5 Pack, and I am extremely satisfied with my decision to make this eco-friendly switch in my bathroom routine. These natural sisal soap savers not only promote zero waste and plastic-free living, but they also provide a range of benefits that make them a perfect addition to any bathroom. The soap bags are made from high-quality natural sisal, which is a sustainable, biodegradable material. This means that once the soap saver reaches the end of its life, I can dispose of it without worrying about contributing to environmental pollution. The soap bags are also very durable and can withstand daily use without falling apart or losing their shape. One of the key benefits of using these soap savers is that they help extend the life of my soap bars. The bags create a rich lather while gently exfoliating my skin, ensuring I get the most out of each soap bar. The soap saver also prevents the soap from becoming soggy, as it allows for proper air circulation and drainage, keeping the soap dry between uses. The E-Know Soap Bag pack comes with 5 soap savers, which is great value for money. I can use them for different soap bars or share them with my family members. The drawstring closure makes it easy to insert and remove the soap, and it also allows me to hang the soap saver up to dry after use. In summary, the E-Know Soap Bag 5 Pack has been a fantastic addition to my bathroom routine. It promotes a more sustainable, plastic-free lifestyle while providing the benefits of a gentle exfoliating scrub and longer-lasting soap. I highly recommend these soap savers to anyone looking to make eco-friendly changes in their daily life.

Makes bar soap better
Color: 5 Pack, Color: 5 Pack
I recently switched back to bar soap because I wanted to save money on bath products, having to shower twice a day at work during the pandemic. These little pouches are soft, but have enough fiber to be mildly exfoliating but not abrasive. The rubbing motion of the fiber on the soap bar while washing actually increases the lather beyond what you would get with the bar alone. The sisal fiber also absorbs the oils and scents of the bar, and I noticed that the smell of the soap was stronger on my skin after showering. I am a man, and it is soft enough for your face and naughty bits. You also don’t waste any soap, as the pouch holds your bar even after it shrinks down and breaks. It also hangs conveniently on my shower rack. I have been using Dove white beauty bars with these pouches and I have noticed my skin is noticeably less dry and softer. NOTE: the pouches do have a slight odor like hay or dry wood when they come out of the box (there is a warning on the package), but it goes away quickly on your first use. If you use bar soap you should definitely give these a try!
