Quick Start Guide
Your NAD+ Pen Kit includes everything you need for effortless, self-administered subcutaneous injections. Ensuring high bioavailability and maximum absorption. By bypassing the digestive system, NAD+ enters directly into your bloodstream, delivering fast, effective results at the cellular level.
Each 500mg/3ml NAD+ cartridge provides 10 doses of 50mg (0.3ml per dose). Your kit includes two cartridges for a total of 20 doses. Upon arrival, the liquid may appear clear or slightly yellow-tinted—this is normal. Store your cartridges in the fridge for optimal potency.
Following the recommended schedule, one dose per day for the first three days, then switching to every other day. Your kit should last approximately 5 weeks. However, NAD+ needs are personal; some users prefer daily use, while others opt for 1-2 times per week. Listen to your body and adjust accordingly.

Most people don’t experience any side effects and report feeling alert and energised. If you do feel anything unusual, such as temporary fatigue for a day or two, which can happen but is rare, stop using, and email doctor@nadaid.co.uk.
Are there any contraindications for using NAD+?
Yes, NAD+ may not be suitable for individuals with the following conditions:
Active or historic Cancer
Pregnancy or breastfeeding
Lyme disease
Recent skin graft
Atrial fibrillation
Immunosuppression
Organ transplant
Haemophilus influenza bacteria
Other NAD-dependent bacteria
If you have any of these conditions, we recommend consulting your healthcare provider before using NAD+.
What colour is my NAD+ AT HOME solution?
Your NAD+ AT HOME solution arrives as a transparent liquid, either colourless or with a yellow tint.
How should I dispose of the needles?
Dispose of any used needles in the designated sharps bin. When disposing of needles, it’s important to be cautious and ensure that they are not sticking out of the bin. This helps ensure a clean and responsible process.
No-one was home to receive my order. Will the NAD+ be ok unrefrigerated?
To put your mind at ease, NAD remains stable at room temperature for several weeks. It only begins to degrade after being exposed to temperatures above 30°C / 85°F for a few days. Even then, it is not harmful, though it may lose some efficacy.
For your convenience, we include cold pouches in the travel case to maintain optimal conditions in transit.
For optimal freshness, we recommend storing NAD in the refrigerator upon arrival and after opening, keeping it away from bright light and extreme heat.
Will the injection hurt?
The injection can sting sometimes & bruises are not uncommon. Try removing the NAD+ from the fridge for 30 minutes beforehand as it can sting more when it’s cold.
Try various injection sites and a new one each time and a 45-degree angle can help. We hear frequently from customers that 1 day it can sting and feel a little sore afterwards & other days it’s painless and sting-free.
Where's best to inject?
The syringes provided are intended for subcutaneous injections, which involve administering the injection just under the skin into the fatty tissue.
We suggest using areas like the stomach, hips, or buttocks for these injections.
To administer, pinch the skin tightly between your finger and thumb with one hand, and with the syringe in your other hand, inject at a 45-degree angle. It’s important to rotate the injection site each time to avoid skin irritation.
It’s normal to occasionally experience a bruise or a small bump at the injection site; simply make sure to inject in a different area for your next dose.
What is NAD?
NAD, or nicotinamide adenine dinucleotide, is a coenzyme found in every living cell in our bodies. It is a crucial molecule involved in many biological processes, acting as a helper molecule for various enzymes to facilitate essential chemical reactions.
NAD exists in two forms: the oxidised form (NAD+) and the reduced form (NADH). The interconversion between these two forms plays a vital role in maintaining cellular health and function.
How often should I use NAD+ AT HOME injections?
If you’re a first-time user of NAD+ AT HOME injections, we suggest administering a micro-injectable daily for the initial 3 days, followed by every other day thereafter. Always adhere to the recommended dosage and never share your product with others.
Are there side effects from NAD+ AT HOME injections?
The majority of individuals do not encounter any adverse effects from using NAD+ AT HOME injections.
Should you experience any sensitivity after using the micro-injectables, consider selecting a different site on your body for the next injection. As with any side effect, if symptoms continue, cease use and get in touch with our team. It is important to note that our NAD+ supplement product is intended for use as directed and should not be used to diagnose, treat, cure, or prevent any disease without consulting with a healthcare professional. For more information, please visit our FAQ’s.
Can I take NAD+ whilst I’m pregnant?
We do not recommend taking NAD+ supplements if you are pregnant or breastfeeding.
What is the shelf life of the NAD+ product?
If unopened, it maintains its quality for 12 months.
Do NAD+ supplements work?
