"What the hell are you swallowing?"

"Amino acids," I answered, while choking down a handful of "horse pills."

"Amino acids?" My father stared at my skinny 14-year-old body, slack-jawed.

"Yeah, amino acids. These are the building blocks of life. I’ve been reading about it," I said, pointing to my pile of muscle magazines on the floor. "This is how I’m going to get buff and smart."

"Oh." My dad was visibly dumbfounded. I could tell he was wondering how it was that the family doctor had never mentioned any of this.

Twenty years later, many people are still clueless about the importance of consuming enough amino acids. This simple dietary addition can boost lean body mass. And having increased muscle has all sorts of benefits. For example, it can:

ward off diabetes
boost immunity
maximize energy
accelerate metabolism (saving you from developing unsightly belly fat)
prevent osteoporosis

The absolute best source of amino acids is whey isolate. As long as it doesn’t contain adulterants like sugar and artificial flavors, anyone at any age can benefit from its muscle-building effects.

Researchers from the School of Biomedical Sciences reviewed all previous studies done with elderly people who suffered from the muscle-wasting disease sarcopenia and then supplemented with whey isolate. By taking about 45 grams of whey isolate per day, these people were able to drastically increase their muscle mass and strength and reverse the disease.

To get your hands on muscle-building amino acids, purchase Whey Advanced. It contains vitamin C, micellar caseine, and is flavored with stevia. It has zero sugars or artificial flavors. You can mix it in a shake or simply stir it into water.
