2 and 3 i agree, but what is in bcaa that does increase insulin? I just assumed its pure amino/protein. I am missing something.
L-Leucine is one of the three amino acids in BCAA's , it spikes insulin hence why it's good post w/o when low carbing cos it spikes insulin n promotes protein synthesis.
This is why some advise not to eat eggs too early in day due to the concerns of the L-Leucine in the eggs protein content may spike insulin n effect IF &/or blunt cortisol's role in burning fat upon rising .
Collagen is best added to BPC, isn't heat effected.
