Understanding Whey Isolate
Like all whey, whey isolate is a mixture of proteins derived from milk during the cheese-making process. Whey proteins can also be consumed in concentrate and hydrolysate form. These have their own unique benefits.
Whey proteins are highly bioavailable, which means they enter the bloodstream quickly. Whey isolate not only contains the highest percentage of bioavailable proteins, its refining process also leaves it with less than 0.1 gram of lactose per tablespoon. By comparison, one cup of milk contains about 10 grams. We can see why it’s been deemed the perfect post-workout solution.
Whey’s Anabolic Effects
When we work out, our bodies go into a process of molecular breakdown. Breaking useful components down into their smaller constituents keeps our bodies working even after we've exhausted readily-available stores of glucose and ATP.
Whey isolate helps to reverse the process of molecular breakdown quickly and effectively immediately after working out, so that a breakdown of muscle does not occur.
Amino Acids in Whey
Whey contains all nine essential amino acids. Don't remember what amino acids do? Simply put, they are the building blocks of proteins. Amino acids affect connective tissues, bones, muscles and cells, but your body can only make 13 of the required 22. The rest must come from food.
With a balanced diet, all nine essential amino acids are relatively easy to find in common foods, but whey isolate makes them all available faster in much higher concentrations.
The term branched-chain amino acid refers to a “branched” atom structure. Of the nine essential amino acids, three are branch-chained: threonine, tryptophan and valine.
Branch-chained amino acids play a very unique role in protein synthesis for muscles, collagen and elastin. Additionally, BCAAs regulate the immune system, help supply glucose while working out to prevent muscle breakdown and release growth hormone. This is why BCAAs are considered vital components of muscle gain and recovery.
Whey isolate's high concentrations of fast-digesting branch-chained amino acids help to boost the effects of weight training and are crucial to preventing fatigue and muscle breakdown while encouraging cell repair and generation during and after a workout.
We only utilize dairy from grass-fed cows to create our whey proteins. Unlike traditional farm feed, which contains high concentrations of cheap calorie sources from corn and soy, LifeSource cows are fed grass. Grass-fed cows produce more nutritionally dense milk without compromising the omega 3 to 6 ratio. The result is a product that’s well-rounded and free of hormones, antibiotics and pesticides, and a cow that’s healthier and happier all around.
