1. Whey protein concentrate (Max BV of 104)
This protein was the first isolated whey, but with the emergency of isolates, it has become perfectly useless. At only 4 Points more on the BV scale, it may be wiser to supplement with an egg protein, the preferred protein source of bodybuilders as early as the 30’s. Whey concentrate has taken on a life of its own in the industry because most companies are too cheap to use all whey isolates, and it’s used as a sort of suffering of protein, just so they can say they use only whey protein. The actual use is slim. It’s basically of a similar make-up as the isolate version, but less BIOAVAILABLE. If you find WPI too expensive though and you already eat a dozen eggs a day, it’s better than nothing and it’s often a good buy in pure form. But those of you looking for Professional gains should probably pass up on WPC.
2. Whey protein isolate (Max BV of 157)
This is the highest yield of protein currently available and is a derivative of milk protein. It’s short chains and peptides make it available for absorption within ten minutes of ingestion sometimes. It’s kind of a protein booster. If you asked which protein is best to invest in, WPI would be it. No sane dietician would tell you otherwise. But caution is the key. Taking in more than 30 grams at once is not advisable because of its short-lived half-life. The best way to counter this effect a bit is to mix it in milk and not water. As explained earlier, the casein in milk protein slows down the digestion of the whey protein, which may give it more time to absorb. It’s a bit of a Time-release mechanism.
Whey is the best investment because of its capacity as a post- workout recovery supplement— that critical time after severe physical stress, when the cells will act like a sponge and take in almost anything. The extreme hunger of the cells and the Fast-acting properties of whey will make sure you use the best window for recovery to the fullest. If not, the body will hunt the stored reserves of nutrients and when on a diet, it also supplies the most amino acids bodybuilders use. It’s unfortunate high cost, however, makes one advise to use it sparingly. When on low- carb diets, whey can function as an alternate source of energy, sparing hard-earned muscle protein and glutamine stores within the body.
