Early evidence

Coenzyme found in every cell. Discussed around cellular energy and aging, in injectable and sublingual forms.

NAD+ (nicotinamide adenine dinucleotide) is a coenzyme found in every cell, central to turning food into cellular energy and to cellular repair. Levels are described as declining with age, which is why it comes up in longevity and energy conversations.

It shows up in a few forms. TRKD+ lists an injectable NAD+ and a sublingual (under-the-tongue) NAD+; the injectable route is discussed as higher-absorption, while sublingual is the needle-free option. Both sit at an Early evidence tier.

TRKD+ describes NAD+ and lets you track whichever form you use. It does not recommend it or provide dosing. A licensed provider is the right source.
