Common, Mild Side Effects

Most people who use NAD+ injections experience nothing beyond mild, short-lived reactions at the injection site — soreness, redness, or slight swelling. Some users also report temporary flushing, mild nausea, or a headache shortly after a dose, which typically resolves within a day.

Serious reactions are uncommon but can include allergic responses such as difficulty breathing or facial swelling, and cardiovascular symptoms like irregular heartbeat or chest pain. Anyone experiencing these should stop use and seek medical attention immediately.

Who Should Avoid NAD+ Injections

How to Reduce Your Risk

Following the supplied instructions closely — including rotating injection sites, using a new micro-needle each time, and not exceeding the recommended dose — helps minimise the chance of a reaction.
