Will you get a small benefit?

I can't.

I've never personally felt like a blood flow benefit from eating a bunch of beets.

Personally, some people say that they do, but you wouldn't get the dosage.

That's why they're juiced.

That's why they're concentrated.

Okay, so you're probably pretty aware of nitric oxide metabolism.

You can't just consume nitric oxide.

Nitrite, nitrate, like immediately, like you're toast, right?

So then the argument is, oh, can we go back up the chain?

Like, can we go up to arginine?

Can we go back up the thing?

So the first stop on that train was arginine.

And then the issue you're going to fall out there, which is almost always the case with supplementation, was bioavailability.

Like, how can we just get enough of it?

And that one just seemed to fail.

It just seemed to get better once we started going there.

And then there's other concerns, cold sores and things like that that started popping up that people were, like, not super stoked about.

And so citrulline seems to be the better approach to that right now.

That's the short version.
