Each kit includes a 1000mg NAD+ vial, sterile micro-needles (8mm gauge), bacteriostatic water for reconstitution, alcohol swabs, full written instructions, and access to guided video support from our clinical nurse Georgina. Everything you need for a safe, effective first injection is included.

The Injection Kit uses a traditional subcutaneous (SubQ) method with a syringe and needle. The Injection Pen is an auto-injector device — simply click and the pen delivers the dose. Both achieve near-identical bioavailability. The pen is ideal for those who want a more streamlined, confidence-inspiring experience. It is also refillable, making it more economical long-term.

Standard oral NAD+ has very low bioavailability (~10–30%). Our Liposomal Capsules use phospholipid encapsulation technology to dramatically improve absorption — reaching ~70–85% bioavailability. They are a highly effective alternative for those who prefer not to use needles, though injectable forms still provide the fastest and most complete delivery.

Most customers begin with one injection per week for the first month, then move to every 2–4 weeks for maintenance. For the Liposomal Capsules, daily use is recommended. Individual goals and physiology vary — our clinical team can provide a personalised protocol during onboarding.

NAD+ At Home products are administered via subcutaneous injection — meaning just beneath the skin. Common sites include the abdomen (2 inches either side of the navel), the outer thigh, or the upper arm. Full visual and video guidance is provided with every kit. Our nurse Georgina walks you through the process step by step.

Many customers report feeling a noticeable increase in energy and mental clarity within 24–72 hours of their first injection. Deeper benefits — such as improved sleep, skin quality, and athletic performance — typically become more pronounced after 2–4 weeks of consistent use. Results vary by individual baseline NAD+ levels.

NAD+ is supplied in lyophilised (freeze-dried) powder form to preserve potency. Simply draw up the provided bacteriostatic water using your syringe, inject it into the vial, and gently swirl (do not shake) until fully dissolved. Full video instructions are provided in every kit. The reconstituted solution should be stored in the fridge and used within 30 days.

Yes. NAD+ is a naturally occurring molecule in every cell in your body. Our products are tested for sterility and pharmaceutical-grade purity. SubQ administration (as opposed to IV) has an excellent safety profile. Each batch is certified, and clinical support is available throughout your journey. As with any supplement, we recommend consulting your GP if you have pre-existing health conditions.

NAD+ is well tolerated by the vast majority of users. The most commonly reported experiences are a warm flush sensation or mild fatigue on the first use — both signs that your body is responding. These typically resolve within a few hours. Mild injection site redness is occasionally reported and is transient. Serious adverse events are extremely rare with subcutaneous administration.

We do not recommend NAD+ supplementation during pregnancy or breastfeeding without explicit GP approval. If you are on prescription medication, please consult your doctor before use. Our clinical team is available to discuss your individual circumstances and liaise with your healthcare provider if needed.

NAD+ is classified as a wellness supplement in the UK, not a prescription-only medicine. Our products are manufactured under strict quality controls and are compliant with applicable UK supplement regulations. Every batch undergoes third-party testing for purity, sterility, and potency before release.
