There are four main methods to increase NAD+ levels:
- Orally: Pills are available, but absorption is low, and there are concerns about the safety of precursor supplements.
- Intravenously: IV drips provide a rapid boost but are uncomfortable and require medical supervision.
- Intramuscularly: Effective but painful and requires careful handling.
- Sub-cutaneous injection: The VAION+ PEN offers a pain-free, convenient way to maintain NAD+ levels by administering doses just under the skin.
