Branched Chain Amino Acids (BCAA’s)


One of the first things that I learned about in the field of Nutrition, was the importance of Branched Chain Amino Acids, or more commonly referred to as BCAA’s. The three BCAA’s are Leucine, Isoleucine, & Valine. These amino acids make up 1/3 of muscle protein, and even during moderate exercise, the total daily requirement of branched chain amino acids is significantly reduced from our bodies through oxidation. This makes it especially important for those who regularly exercise, and vital for athletes to replenish these building blocks. To ensure that a sufficient supply of BCAA’s is present in our bodies, we must consume adequate amounts of BCAA’s, whether it is in food or supplement form, to increase the BCAA’s in our blood. While we do replenish some BCAA’s through eating high protein foods, levels are most likely to be still in a depleted state for athletes. Adding a supplement may help to replenish the levels to a more adequate state. A good singular free- form L-amino acid supplement that my wife and I use, that provides a good ratio of the three Branched Chain Amino Acids plus additional Glutamine, (for maintaining lean muscle tissue,) is Xtend BCAA’s. We have been using this supplement for a month now, and we have seen an improvement in our training & recovery.


We both train very hard, continuously putting our bodies through intense exercise, both anaerobic & aerobic, so replenishing these important nutrients is so important for repair of tissue on a cellular level. Back in the early 90’s, when I was part of Nutritionalysis, I consistently had BCAA’s as part of my daily supplement regimen. Over the years, I eliminated such things do to cost and the financial priorities of a family & a home. I truly feel the difference in this month’s work-outs, having returned to this important supporting nutrient ratio! It’s really a great addition to my regimen, and my body is thanking me! I highly recommend Xtend BCAA’s, especially if you are a physically active person.* I hope that you experience the improvement in your work-outs as we did.

Until next month, (and may it be a month with great work-outs!),
