These days, dairy companies recognize the value of whey and have set up factories to concentrate and purify it. Way back when, whey was actually considered a waste byproduct of cheese production and was routinely dumped. But if you think that supplement companies like Optimum, Cytosport or Nature’s Best are out in the back milking cows to make their protein powders, you’ve got another think coming. Cows are milked on the farm, and this milk is the starting source for most protein powders. If you know that whey is one of the proteins found in milk, then it should be obvious that whey protein production starts with dairy cows. In fewer than 30 minutes it can fast-track a good portion of its aminos to your muscles, and that rapid delivery of amino acids to muscle cells has been shown to be important for pushing muscle growth. These provide antioxidant benefits, boost immune function and enhance muscle recovery and growth.īut probably the most critical factor that puts whey protein miles ahead of other forms of protein is digestion rate. Whey protein also contains biologically active protein microfractions such as alpha-lactalbumin, beta-lactoglobulin, glycomacropeptides, immunoglobulins, lactoferrin, lactoperoxidase and various growth factors. These bad boys have been shown to be absolutely critical for muscle growth, and even for energy during workouts.
Whey is one of the richest sources of BCAAs, which include the three amino acids leucine, isoleucine and valine. Just to review, whey is enormously beneficial for several reasons, including amino acid and microfraction content (more on that in a minute) and digestion rate. You’ve recognized whey’s benefits and have included it in your daily regimen. The first step in determining whether your protein is worthy is to give yourself a pat on the back. And being able to tell the difference between them can be critical to your gains. There are great whey protein products and there are not-so-good whey protein products. You know that taking whey protein at the right times of day can make all the difference in between building an extra half-inch on your arms or adding 20 pounds to your personal best on the bench press.
The truth is, these are serious questions. How do you choose a whey protein powder? Do you go on the recommendation of your buddy at the gym and take what he takes? Do you pick the bottle with the shiniest, most cutting-edge label? Do you go by what tastes good or what’s on sale at your local GNC?
