Okay, so I mentioned the long COVID trial that we published recently. There's a substance that we kind of use in combination called NAD. NAD is Nicotinamide Adenine Dinucleotide. I think I pronounced that right. It's a molecule, probably everybody heard of in high school biology is part of the Krebs cycle. You can read more about it, but it's NAD also frequently called NAD plus.
