As a pharmacist I often hear: I take supplements, but I barely notice anything. The right form of an ingredient often matters far more than the amount.

If an ingredient isn't absorbed well, you can take as much of it as you like: it will never reach the effect you're looking for. That's why a good supplement starts with absorption, not with the label.
ABSORPTIX®ABSORPTIX® is our formulation logic, developed together with doctors and pharmacists. The goal: have every ingredient absorbed as well as possible. For that we focus on three things.
| Typical supplement |  | |
|---|---|---|
| Starting point | What's inside? | What does your body absorb? |
| Ingredients | As many as possible | The right ones, in the right form |
| Dosage | The more mg, the better | Tuned to absorption |
| Form | Often the cheapest form | Active, well-absorbed forms |
| NAD+ | NAD+ itself | NR, which your body turns into NAD+ |
Your body has millions of cells working every day. Think of NAD+ as a taxi that makes sure every cell can do its job, such as making energy. NAD+ declines as you get older. Taking NAD+ itself makes little sense, because your body absorbs it poorly. NR is a small precursor your body converts into NAD+ itself.

Taking NAD+ as a supplement makes little sense. That's why we choose NR, a small building block your body converts into NAD+.
