Hi
I think that the oringinal mention was here

I would not think that there was much advantage in buying this particular brand.
As
@Murph explained the advantage was the high levels of available leucine and lysine.
If you go to the relevant wikipedia pages
https://en.wikipedia.org/wiki/Glucogenic_amino_acid and
https://en.wikipedia.org/wiki/Glucogenic_amino_acid you will find that amino acids vcan be divided into those that can be used to make glucose and those that can be broken down to make ketone bodies.
If you go to this page
http://themedicalbiochemistrypage.org/amino-acid-metabolism.php and follow the links you will find that it is much more complicated.
But the central idea, "If you are unable to turn glucose into energy use amino acids or lipids" makes sense to me.
Over November and December I played around with mixtures of amino acids trying to make this work.
I used amino acids in part because according to the model that CFS discovery and the Melbourne research team are working on our metabolic disfunction leads us to be deficient in the digestive enzymes needed to break proteins into the amino acids and short peptides that we can absorb.
You could just get some leucine. Examine
https://examine.com/supplements/leucine/ says that the upper tolerable limit for supplementation is 500mg/Kg body weight.
One downside for some people might be that it stimulates insulin. (Making it harder to access fat stores and make energy from lipids.)
My preference was to use an amino acid mix, on the assumption that my long standing issues with digestion would mean that I was generally low in some of these amino acids. I played around with a mix called future whey that I would not recommend as it contains sugar alcohols and I do not like diarrohea. I also used an EAA mix which was better.
I made these mixtures up with 12.5g amino acids 3.5g salt 2.25g potassium chloride and 2g bicarbonate of soda (NaHCO3). I have PoTS and need the salt and potassium anyway, but the salt and bicarb in this mixture helps by providing the sodium for the sodium dependent amino acid transporters that we all use to absorb amino acids from our intestines.
Made this way it is absorbed very quickly. I found that it really helped with PoTS.
But I am still playing around with these things and trying to get the right balance for me.
