Whey protein supplements are considered one of the best sources of protein for muscle building and fat burning. The reason behind its success is that whey protein has one of the best protein ratings in terms of amino acid composition and digestibility. Whey contains essential and branched-chain amino acids which may help raising the amount of amino acids available in your body for the muscle growth process, also known as muscle protein synthesis.
However, some people may find it a little bit complicated to choose and buy the right whey supplement so often recommend by nutritionists and fitness trainers. Some products are labeled whey isolates while others are whey concentrate. What is the difference? Which one is better?
The main nutritional difference between whey concentrate protein and its whey isolate protein is the amount of protein, lactose and fat present. For example, a whey concentrate protein powder contains in average around 12% of protein, 70% of lactose and roughly 1.5% of milk fat. On the other hand, whey protein isolate products contain over 90% protein, less than 1% of lactose and just 0.5% of milk fat. So, the next question is: how does that happen?
Whey protein isolate is created by filtering whey protein through a micro filter to remove the lactose and ash in the product. This unique process creates a product that is much higher in protein than a regular whey protein and is also rich in immunoglobulins, alpha-lactalbumin, beta-lactoalbumin, and other immune boosting factors. As a result of the nature of whey, the purification process is a low-heat, spray-dry method that does not use any solvents, ensuring that the final result is a natural and chemical-free product.
Whey protein builds lean body mass by helping to increase your body’s production of muscle protein, which is especially important after intense workouts.
