# Nicotinamide riboside: oral supplements

Understand NAD+ precursors, product checks and limits of the evidence.

**What you need to know**

Nicotinamide riboside is an oral NAD+ precursor. Novel-food authorisation has ingredient specifications and conditions of use; it is not a medicinal licence or proof of an anti-ageing benefit. Check the exact product against current Great Britain requirements and read our NAD+ evidence guide.

This is an educational guide. Sanara is not taking orders or preorders. Compare the actual product’s label, suitability and total cost before buying from a retailer.
