BCAA's

[Gooseneck]

Just wondering how yall felt about supplementing amino's in with your daily diets. I've just recently starting taking these twice a day; first thing in the morning and directly after my workouts.

Re: BCAA's

I think we get plenty of amino's from the protein we get from food and protein shakes. I do supplement with extra Taurine and Glutamine though.

Re: BCAA's

This is why supplemental BCAA's are usless (biologically speaking)...

The pituitary is stimulated to release GH by another hormone circulating in the brain, called somatrocrinin. Levels of somacrinin can be incresed by increasing levels of brain neurotransmitters. Neurotransmitters are the chemicals that carry information from one nerve to another. Their activity constitues your mind, your conciouness, all your schemes and dreams. So before you mess with them you better know what you are doing.

To increase neurotransmitters, you have to get the amino acids that influence them past what is called the blood-brain barrier. That is a system designed to protect the brain. To cross the barrier, amino acids have to be carried by specific transport molecules. The transport capacity is very limited and once it is full, no more aminos get across for some time.

As I stated above, there are four different types of transporter. Each will carry only one specific class of amino acids. The four are Large Neutral, Small Neutral, Acidic and Basic.

Large Neutral: Trytophan, Phenylalanine, Tyrosine, Methionine, Hisidine, Leucine, Isoleucine and Valine
Small Neutral: Asparagine, Glutamine, Proline and Serine.
Acidic: Latamic Acid and Aspartic Acid.
Basic: Arginine, Ornithine and Lysine.

As you can see if you want your aminos to work for you you have to take them alone. For instance a supplement of Trytophan, Glutamine, and Arginine would be a great combo. There is one unassigned amino Glycine that has been proven to release GH too, but it's much weaker. The strongest are Tryptophan, Glutimine, Arginine, Ornithine (in the form of ornithine alpha-ketogluterate) and Lysine.

Re: BCAA's

I've read both sides of the story. My own personal experience is that I couldn't tell a difference either way.
