What is NAD+ and what does it do for the body?

NAD+ (Nicotinamide Adenine Dinucleotide) is a vital coenzyme found in every cell that plays a key role in converting food into energy, supporting DNA repair, and regulating metabolic activity. Because natural NAD+ levels decline with age, self-administered injections can restore cellular health and help improve energy, focus, and longevity.

What is the typical dosage schedule for NAD+ injections?

The recommended dosage for Vivere NAD+ injections is 50mg per day, which equals 15 units on the pen. For the best results, you should inject 50mg daily for the first three days as a loading phase, and then drop to a maintenance routine of 50mg every other day.

Where is the best place to inject NAD+?

NAD+ should be injected subcutaneously into areas with muscle or fatty tissue, such as the lower abdomen, the upper thigh, or the buttocks. It is important to rotate your injection sites regularly to improve comfort and support proper absorption of the coenzyme.

Do NAD+ injections have any side effects?

While most people tolerate NAD+ injections well, you may experience mild, short-lived side effects such as nausea, headaches, light-headedness, fatigue, skin flushing, or slight discomfort at the injection site. If you notice any severe or ongoing side effects, you should stop using the product immediately and seek medical advice.

How should I store my NAD+ cartridges?

You should store your NAD+ cartridges in the fridge at a constant temperature between 2°C and 8°C, which keeps them effective for up to 24 months. Before administering an injection, allow the cartridge to sit at room temperature for 2 to 3 minutes to make the injection more comfortable.

Why do 1000mg NAD+ cartridges look more yellow than 500mg cartridges?

The 1000mg NAD+ cartridges naturally appear more yellow because they contain a much higher concentration of the active ingredient, which absorbs more light. This colour variation is completely normal for concentrated supplements and does not affect the safety, purity, or effectiveness of the product.

Do I need a prescription to buy NAD+ injections in the UK?

No, you do not need a prescription to purchase Vivere's NAD+ injection pens or cartridges in the UK. However, if you have active cancer, a history of cancer, or liver and kidney conditions, you must consult your healthcare provider before starting NAD+ therapy.
