What you WON'T FIND in NutraBio Grass Fed Whey Isolate:
- Proprietary blends or amino spiking. We provide full label/ingredient disclosure on our Grass Fed Whey Isolate. No games, no tricks-just the purest, freshest whey isolate available.
- Inferior sources of protein, such as low quality whey concentrates or soy that, gram for gram, are not as pure as whey isolates
- Extra amino acids like taurine or glycine used by some brands to boost nitrogen content and fool you into thinking you are getting more protein than you really are
- Ion exchange or acid-treated whey, which destroys the natural non-denatured state of whey, causing it to lose its anti-cancer and immune stimulating activity
- Fillers, excipients, maltodextrin or dextrose, added sugar or carbs, artificial colors, GMOs, or banned substances
No other macronutrient is more essential to muscle growth and recovery than protein. Research shows that active individuals need 1.5–2.2 grams of protein per kilogram of bodyweight daily for optimal nitrogen balance and to promote muscle growth/recovery. This amount is often difficult to meet through a balanced diet, which is why individuals often turn to whey supplementation to support their protein requirements. However, not all whey proteins are created equal. In a market saturated with hundreds of whey proteins, it is hard to know that what you see on the label is what you are actually getting. Many companies use confusing labels and deceptive claims to hide lower quality proteins and cheap ingredients. Therefore, full label disclosure, quality, digestion rate, and preparation method should all be considered before selecting a whey protein.
The most common forms of whey are whey protein isolate and whey protein concentrate. Whey protein isolates digest and absorb rapidly and are, gram for gram, the purest form of protein available (90–98% pure protein). This level of purity is achieved through a cold cross-flow micro- and ultra-filtration process that removes the larger, less-absorbable protein molecules while also filtering out fat, lactose, and ash that can be present in whey concentrates and substandard protein powders. Furthermore, this process does not denature the valuable proteins and peptides in whey, so the protein itself is of a higher quality.
Studies suggest the ingestion of fast-acting protein sources, such as whey isolates, can increase amino acid levels in systemic circulation and stimulate robust increases in protein synthesis, arguably the most important physiological factor in existence when it comes to muscle growth, strength, and recovery. What's more, since whey protein isolates are generally low in carbs, lactose free, fat free, cholesterol free, and gluten free, it makes it the perfect choice for low-carb dieters, lactose intolerant individuals, or athletes who want to get ripped while packing on muscle. Simply put, isolates are the king of the whey protein jungle.
On the other hand, whey concentrates contain less protein on a gram for gram basis. The process used to create whey concentrates does not go through as many fine filtration steps, resulting in a product that can be anywhere from 25–80% pure protein. Furthermore, whey concentrates, due to the filtration process used, contain higher amounts of fat, cholesterol, and lactose, the last of which may cause gastrointestinal distress and bloating in some individuals.
When taking a product containing whey concentrate, it may be a guessing game as to how much pure protein you are getting per serving. Look closely at the label-unless it says whey protein concentrate 80 (WPC 80), you may be getting a lower quality protein, cheating you of the muscle building and recovery benefits of a higher quality protein. Unfortunately, using lower quality whey concentrates in a protein powder is a common tactic used by unscrupulous supplement companies in order to pad their bottom lines at your expense. The label may still proclaim 100% whey, but the quality of that whey may be as little as 25% pure protein. In summary, whey concentrates are a lower quality and cheaper grade protein compared to whey isolates, and it is best to avoid using products that contain a whey concentrate where the purity is unknown.
