So a lot of people who are taking workout supplements at night for recovery, like take one that's, if you're taking aminos at night, branched chain amino acids in general could be good for recovery, especially after training.

And if it's got some extra glycine in it, all the better.

But if it's got a lot of glutamine in it, you want to not be using that because glutamine is activating.

And so, I mean, I've had athletes I've worked with who like complained, complained about their insomnia.

Turns out they're taking these nighttime supplements with a whole bunch of glutamine in it.

And that's sort of what's counter, that's what's getting in their way.

So it's not just about supplements at night that can be helpful.

It's avoiding stuff that can get in the way, like B12.

B vitamins are good to take at night because they can help with recovery.

B12 help boosts the ability of light to suppress melatonin.

You don't want to take that at night.

You want to take that in the morning.

B12 is great in the morning because it can help wake you up a little more for a bunch of reasons, including its ability to help light suppress melatonin.

But you don't want it at night when even a little bit of light can start getting in the way.

Yeah.

I have this dream one day of having like an AM vitamin and a PM vitamin where like some stuff might be better at night.

Like you want to, if sleep is all about recovery and repair, put those raw materials in play at the time you want to use them.

If they're going to degrade or you could just take them in the morning if they're going to hang out all day anyway.

But yeah, I mean, some of that multivitamin you might want to take in the morning.

Totally separate.
