What company? And was it specifically leucine attached to nitrate or something else?
it was scifit. they used a liposomal delivery that guarantees total absorption; they claimed the I pill I took was equal to 7 grams though I questioned whether leucine absorption was as bad as they claimed, the fact is lypomal delivery is king and its used in drugs and a few other cutting edge things out there. it also claimed to be sustained release, and since Ive had great success with sustained release aminos before I tried it. I was so excited I got my old man on it, but he didn't notice any improvement in his lifting. from what I can tell the company was shut down.
no nitrates were in it. that's a different animal, but if youre a bodybuilder, nitrate is a welcome addition. that said, there are people taking the 7grams of leucine a day. I don't know how much leucine per serving is in it, but I would guess nowhere near 7grams, given that would amount to alotta nitrate. that said, I vaguely remember reading something about nitrates improving absorption of aminos..
