All of which is of no practical value. Through normal production of protein powders, be it whey, casein, etc, the ratio of amino’s are not changed. The standard protein scoring systems (PER, NPU, BV, etc) apply as usual, and there’s no reason to attempt taking into account D amino acids as the proteins are in their normal state.
If you are taking actual individual aminos, then it could be an issue, but you will also find they are listed as L form, with the rare occasion some D form has in fact been shown to have some biological effects.
No supplement companies attempt to account for D forms to trump up numbers, nor would they bother adding additional aminos in their D forms. Supp companies pull a lot of shady stuff, but that’s not one of them.
I do consulting work, R&D, etc for such companies, as well as major whey manufacturers, and 3 years of chem, including a year of bio chem, and your info is not correct.
So you’re telling me that all supplement companies don’t cheat and use garbage protein? And you’re saying that the body can absorb all of the protein it ingests?
Fact is, I don’t care that much to argue. I don’t take supplements myself. I don’t see the use for them. If it cannot be achieved with hard work and a good diet it just isn’t meant to be -and I’ve seen plenty of the guys do all their vomitous concoctions and their feeding schedules and pills and injections and what not while overseas. I’ve also seen them deflate like balloons when coming home.
Hard work and a good diet is where it is. There is no easy out.
How are you defining “garbage”? Regardless, low grade proteins they may use would be low grade due to things like higher lactose, ash, etc, or not well process (high heat, etc) leading to a high % of denatured proteins so their BV is poor, but it has nothing to do with any changes in L vs D aminos.
I didnt mean to start a chemistry argument. I just wanted to let people who struggle to choke down a post workout supplement that there is a really good tasting protien that performs really well. And the whole thing about a good diet being the end all be all is bullshit imo. the fact is that a supplement is just that a supplement to your diet. If you choose to eat 14 eggs a day that is your choice. I would rather eat chicken breast for dinner and a protien supplement after I work out. My muscle recovery is much faster since I started taking the SYNTHA6.
