NAD+

How it works

Your body uses NAD+ for energy and to repair DNA. Levels drop with age, which is why people try to top them up.

What people use it for

• Energy and focus
• "Anti-ageing"
• Recovery

What the research shows

• Small human studies, mainly with tablets (NR or NMN) that the body turns into NAD+.
• Clear health benefits in healthy people have not been shown.

Side effects & risks

• Drips often cause flushing, nausea, chest tightness and cramps if given fast
• Injection products are not quality-controlled

Is it legal?

Not approved as a medicine for injection in the EU or US. Oral precursors (NR, NMN) are sold as supplements in some countries.

Storage & safe handling

• Mix with bacteriostatic water: let it run slowly down the inside of the vial and swirl gently — never shake.
• Store the mixed vial in the fridge and follow the use-by period on the label.
• Wipe the vial top with alcohol and use a new sterile needle and syringe every time.
• Rotate injection sites so the same spot is not used again and again.
• Put used needles in a sharps container, not the household bin.
• Get medical help for redness that spreads, fever, swelling or trouble breathing.
