Who Should Avoid NAD+? Contraindications and Precautions

NAD+ isn't suitable for everyone. Pregnant or breastfeeding individuals, children, and people with certain liver or kidney conditions should avoid NAD+ supplementation, and anyone on regular medication should check with a healthcare provider first.

Pregnancy and Breastfeeding

There's currently insufficient safety data on NAD+ use during pregnancy or breastfeeding, so it isn't recommended for people who are pregnant, trying to conceive, or nursing. The potential effects on fetal or infant development haven't been adequately studied, so caution is the safest approach here.

Children and Adolescents

NAD+ supplementation is intended for adult use. It shouldn't be given to children or adolescents unless specifically directed and supervised by a qualified healthcare provider.

Liver or Kidney Conditions

Because the liver and kidneys play a central role in processing and clearing NAD+ and its precursors, people with chronic liver disease, elevated liver enzymes, or kidney dysfunction should avoid supplementation without medical guidance. Compromised organ function can affect how these compounds are metabolised and cleared from the body.

Medication Interactions to Be Aware Of

NAD+ may interact with certain medications, including blood pressure treatments, diabetes medications, and some psychiatric medications, due to overlapping effects on metabolism and blood glucose regulation. If you take any regular prescription medication, it's worth discussing NAD+ supplementation with your GP or pharmacist before starting.

When to Speak to a GP First

If you have an existing health condition, take regular medication, or are simply unsure whether NAD+ is appropriate for you, the safest step is a conversation with your GP before starting. This is especially important for injectable forms, which deliver NAD+ more directly than oral supplements. You can also review our NAD+ safety and side effects guide and check the current MHRA legal status of NAD+ in the UK for additional context.
