Whey Protein Isolate
Protein forms the building blocks for your muscle tissue, so without it your body would lack a critical component needed for muscle to even exist. Whey is one of the best absorbed forms of protein in the body, even higher than chicken or fish.
What is whey protein isolate?
Whey protein isolate (WPI) is the purest form of whey protein powder available. It is derived from cow’s milk and is essential for muscle repair, growth and strength. In contrast to whey protein concentrate, WPI has a much higher pure protein content of over 90%. WPI also contains little to no fat, lactose or cholesterol.
Why take WPI?
Protein is used for the production of muscles. Proteins are also used to manufacture hormones, enzymes, cellular messengers, nucleic acids, and immune-system components. Without adequate protein, our bodies cannot put together the structures that make up every cell, tissue, and organ, nor can it generate the biochemical substances needed for cardiovascular function, muscle contraction, growth, and healing. Without an adequate amount of protein our muscles would not heal up as quickly and could therefore lead to overtraining your muscle which could lead to injury.
When do I take WPI?
Also, after a workout is one of the best time to get protein into the body so that the protein can be delivered to your muscles, to begin healing the micro tears (very small tears in the muscle tissue, caused by intense contraction of the muscle during workout) in the muscle. Post-workout, WPI should be taken as it is absorbed rapidly, so that the synergistic insulin response is maximised – this allows muscle breakdown to diminish so that synthesis can dominate and you can get quickly back into building muscle the next day.
Benefits of having a whey protein shake
Because solid food takes more time to digest and to break down the protein and send it to the muscles, it can be best to take a protein shake immediately following a workout. Protein, through liquid nutrition (your shake) is more rapidly digested and absorbed, thus nutrients are more rapidly delivered to your muscles.
Other benefits of No Bull Supplements’ WPI
• Our WPI is sourced from the USA, one of a few manufacturers in the world that supply WPI at 93g of protein per 100g (dry-basis). Thus, the protein content in our whey protein isolate is superior to all the major brands. We focus on delivering simply pure whey protein
• Our whey protein isolate is a low temperature cross and ultra filtered WPI which remains completely undenatured.

Please note, protein content for cocoa-based flavours may vary by up to 2.5g per 100g.
Studies related to WPI
1. The main disadvantage of WPC is because of the higher level of lactose and fat, this means more calories. So if you are on extremely strict diet and are careful of every calorie that you consume i.e. bodybuilder or athlete before competition; then WPC may not be your choice of whey protein powder. Also the same goes if you are lactose intolerant, WPI may be a better choice: Judy A. Driskell (Ed), Sports Nutrition: Fats and Proteins, CRC Press, 2007, p.146.
2. In a group of healthy adults, in direct comparison to supplementation with casein, WPI supplementation (30 grams/day) improved body composition (maintain lean mass, reduce fat mass) via enhanced antioxidant (GSH) status. This improvement was obtained without exercise training: Lands LC, Grey VL, Smountas AA. Effect of supplementation with a cysteine donor on muscular performance. J Appl Physiol 1999; 87: 1381-1385.
3. With regard to resistance (RE) training specifically, one study reported that a dose of WPI (1.2g/kg/day) in RE-trained individuals resulted in an almost 2-fold higher gain (2.1 vs. 1.2kg) in LBM and a better gain in bench press strength compared to a CHO-supplemented group: Burke DG, Chilibeck PD, Davidson KS, Candow DG, Farthing J, Smith-Palmer T. The effect of whey protein supplementation with and without creatine monohydrate combined with resistance training on lean tissue mass and muscle strength. Int J Sport Nutr Exerc Metab 2001; 11: 349-64.
4. In one investigation dietary analyses concurred that the participant’s eating patterns were characteristic of bodybuilders, i.e., they consumed a high energy/protein intake divided into small, frequent, mixed macronutrient meals over the 24 hour period. The supplement dose (120 grams per day for an 80kg individual) was divided into 4 small doses and consumed with meals throughout the day. In comparison to an equivalent dose of casein, treatment with the WPI resulted in a 5-fold better gain in LBM and better gains in strength after the 10 week RE training program: Cribb, PJ, Williams AD, Hayes A, Carey MF. The effect of whey isolate on strength, body composition and plasma glutamine. Int. J Sports Nutr Exerc Metab 2006; 16: 494-509 Important consideration was use of a supplement dose and protocol that is characteristic of strength athletes.
