NAD+ Injections: Benefits, Dosage & What to Expect

What NAD+ actually does, injectable vs oral options, and how to choose the right dose — given by our clinicians at your home or workplace, or self-administered with our Bio Pen and Home Injection Kit.

NAD+ injections deliver nicotinamide adenine dinucleotide — a coenzyme essential to cellular energy production and DNA repair — directly into the body via injection, bypassing the digestive system that limits how much oral NAD+ actually gets absorbed.

NAD+ levels decline naturally with age, which is why injectable and oral NAD+ supplementation has become one of the most searched-for treatments in clinical wellness. The question most people actually have isn't whether NAD+ matters — it's which delivery method and dose makes sense for them.

What NAD+ actually does

NAD+ is present in every cell in the body and plays a central role in two processes:

Cellular energy production. NAD+ is required for mitochondria to convert food into usable energy — this is the mechanism behind most of the "energy and focus" effects people associate with NAD+.
DNA repair and cellular maintenance. NAD+ is a substrate for enzymes (sirtuins and PARPs) involved in repairing cellular damage, which is part of why NAD+ is widely discussed in longevity and healthy-ageing research.

Natural production slows with age, stress, and poor sleep — which is the rationale behind supplementing it directly, either orally or by injection.

Injectable vs oral NAD+: what's the actual difference

Oral NAD+ has to survive digestion before any of it reaches the bloodstream, which significantly limits absorption. An injectable dose skips that step entirely, which is why injectable NAD+ is generally considered more bioavailable than an oral capsule of the same strength — though oral capsules remain a simple way to support levels daily between injections or protocols.

Boost & Glow's NAD+ injections are not IV drips. Our clinicians give intramuscular NAD+ injections at your home or workplace across Essex, Hertfordshire and London, and our Bio Pen and Home Injection Kit products are self-administered subcutaneous injections.

Who should consider NAD+, and how often

NAD+ is typically used by people looking to support energy, focus and general cellular health, particularly where age, stress or lifestyle factors are likely contributing to lower natural levels. How often to use it depends on the protocol — some start with a single dose, others follow a sustained course using the 2x500mg pen or a refill vial alongside the home kit.

How it works: choose a clinician-given intramuscular NAD+ injection at your home or workplace across Essex, Hertfordshire and London, or self-administer at home with our Bio Pen or Home Injection Kit.

FAQ

What is NAD+ and what does it do?

NAD+ (nicotinamide adenine dinucleotide) is a coenzyme found in every cell in the body, essential for converting food into cellular energy and supporting DNA repair. Natural NAD+ levels decline with age, which is why many people turn to supplementation to help maintain them.

Is injectable NAD+ better than oral NAD+ supplements?

Injectable NAD+ bypasses the digestive system, where oral NAD+ is broken down before much of it can be absorbed. This generally means higher bioavailability from an injectable dose compared with an oral capsule of the same strength, though oral capsules remain a convenient option for daily, lower-dose maintenance.

How are NAD+ injections administered — is it an IV drip?

No. Boost & Glow's NAD+ injections are not IV drips. Our clinicians give intramuscular NAD+ injections at your home or workplace across Essex, Hertfordshire and London, and we also offer self-administered NAD+ Bio Pen and Home Injection Kit products, which are subcutaneous injections.

How often should I have NAD+ injections?

This depends on the individual and the protocol chosen. Some people use a single dose to start, others follow an extended protocol over several weeks. A consultation helps determine the right frequency for your goals.

Can I do NAD+ injections at home?

Yes, in two ways. Our clinicians can come to you and give an intramuscular NAD+ injection at your home or workplace across Essex, Hertfordshire and London. Alternatively, you can self-administer at home with our NAD+ Bio Pen or Home Injection Kit, which are subcutaneous injections.

How much do NAD+ injections cost?

Boost & Glow's injectable NAD+ options start at £245 for a single 500mg Bio Pen, with a Home Injection Kit at £325 and a 500mg refill vial at £300. Oral liposomal NAD+ capsules are available from £75.
