What Is NAD⁺?

NAD⁺ (Nicotinamide Adenine Dinucleotide) is a naturally occurring coenzyme found in every living cell. It plays an essential role in converting the food we eat into usable energy and contributes to normal cellular function.

Derived from vitamin B3, NAD⁺ is involved in several important biological processes that help cells operate efficiently, including DNA maintenance and energy metabolism.

NAD exists in two forms — NAD⁺ (oxidised) and NADH (reduced) — which work together within cells to generate ATP, the main energy molecule used by the body. Without sufficient NAD⁺, normal energy production and cellular repair activity can be affected.

Natural NAD⁺ levels tend to decline gradually with age. This change is an area of ongoing scientific research exploring how NAD⁺ interacts with energy metabolism and cellular maintenance. Some individuals choose to explore professional NAD⁺ programmes as part of a broader focus on wellness and vitality, under clinical supervision.

How NAD⁺ Injection Is Used

The product is designed for subcutaneous use.

The appropriate route, dosage, and frequency should be confirmed by a healthcare professional based on clinical judgment.

Important Information

Not intended for unsupervised injection.
Do not use if the solution appears cloudy or discoloured.
Not for oral consumption.

When to Seek Medical Advice

If, after administration, the individual experiences unexpected reactions such as severe dizziness, difficulty breathing, chest pain, or signs of allergy (swelling, rash, itching), immediate medical assistance should be sought via A&E or 999.

Alternative Products

Those seeking nutritional support through oral intake may consider NAD⁺ precursors such as nicotinamide, nicotinamide riboside (NR), or nicotinamide mononucleotide (NMN).

The NAD+ injection pen delivers NAD+ under the skin via a self-administered subcutaneous injection.

When starting treatment, the pen should be used once daily for three consecutive days, then continued every other day thereafter.

The typical dose is up to 50mg per injection (equivalent to 15 units on the pen when using a 1000mg cartridge).

The pen will come with full step-by-step instructions on how to prepare, inject, store, and safely dispose of needles and cartridges.

Key Points

• Store cartridges in the fridge (2–8°C).
• Allow the pen and cartridge to reach room temperature for 2–3 minutes before use.
• Rotate injection sites (stomach, thigh, or buttock) to prevent irritation.
• Mild redness, a drop of NAD+, or light bruising at the injection site can occur and are normal.
• Always dispose of used needles in a sharps bin.

Active Ingredient:

Nicotinamide Adenine Dinucleotide (NAD⁺)

Inactive Ingredients:

Sterile water for injection
Sodium chloride
Stabilising excipients (as applicable)

Important Note

Before use, patients should always check the full list of ingredients to ensure they do not have any known allergies or sensitivities.

If you have experienced reactions to injectable products in the past, or are unsure whether NAD⁺ Injection is suitable for you, seek professional medical advice before treatment.

Always read the accompanying product leaflet or information supplied for a complete ingredient list and safety guidance.

Like all injectable products, NAD⁺ injections can occasionally cause mild and temporary effects. These are usually short-lived when given by a trained professional under sterile conditions.

Common Effects (usually mild)

Slight pain, redness, or tenderness at the injection site
Warmth or flushing for a few minutes after injection
Temporary tiredness, light-headedness, or mild headache

Less Common or Serious Effects

Allergic reaction (rash, swelling, difficulty breathing)
Feeling faint, rapid heartbeat, or very low blood pressure
Persistent or severe pain or swelling at the injection site

If you develop breathing difficulty, chest pain, or severe dizziness, call 999 or go to your nearest A&E immediately.

If you’re unsure or symptoms continue beyond a few hours hours, contact your GP or call NHS 111 for urgent advice.

Before Treatment

Seek medical guidance if:

You have any allergies or previous reactions to injectable products
You take any other medicines
You have any medical conditions, especially heart, kidney, or liver problems
Do not use during pregnancy or breastfeeding
