How Much Does NAD+ Really Cost Per mg? A UK Value Comparison

Working out the real NAD+ cost per mg is the only reliable way to compare injection kits, because sticker prices alone can be misleading. Based on real, currently published UK prices, NAD+ cost per mg works out to roughly £0.15 to £0.59, with reusable-pen starter kits sitting at the higher end and cartridge-only refills typically coming out cheaper. Here's how to calculate it yourself, and what the numbers actually show.

Why the Sticker Price Doesn't Tell You the Real Story

A kit priced at £295 isn't automatically more expensive than one priced at £175 — it depends entirely on how much NAD+ you're actually getting, and what's included alongside it. Two kits with very different sticker prices can supply a similar amount of usable NAD+, while two kits priced identically can differ several-fold in total mg. Without converting to a per-mg figure, you're really comparing packaging, not product.

The NAD+ Cost Per mg Formula (and How to Use It)

The calculation itself is simple: divide the full price of a kit by the total NAD+ it contains, in milligrams. £295 ÷ 500mg works out to £0.59 per mg. £360 ÷ 1000mg works out to £0.36 per mg. Once you've done this for every kit you're considering, you have a like-for-like figure that holds up across pack sizes, subscription plans, and even different brands.

If a product page doesn't clearly state the total mg in a kit, you can't do this calculation at all — which is itself worth noting about that seller (more on this in the FAQ below).

Real UK NAD+ Kit Prices Compared

Here's how published UK prices for at-home NAD+ kits actually convert to cost per mg, based on prices live at the time of writing (October 2026). The My nad+ figures are our own current prices; the RevIVe Your Health figures are taken from that company's own published product lineup.

Brand	Kit	Price	Total mg	Cost per mg
My nad+	Starter Kit 500mg	£295	500mg	£0.59
My nad+	Complete Wellness Kit 1000mg	£360	1000mg	£0.36
My nad+	Refill Kit (monthly subscription)	from £250/mo	1000mg	£0.25
RevIVe Your Health	Pen Starter Kit 500mg	£175	500mg	£0.35
RevIVe Your Health	Pen Starter Kit 1000mg	£250	1000mg	£0.25
RevIVe Your Health	Pen Starter Kit 2000mg	£325	2000mg	£0.16
RevIVe Your Health	Refill Cartridge Kit 1000mg	£175	1000mg	£0.18
RevIVe Your Health	Refill Cartridge Kit 2000mg	£295	2000mg	£0.15

A couple of patterns stand out. Refill-only cartridges are consistently cheaper per mg than first-time starter kits, for both brands. And cost per mg tends to fall as pack size increases, because the fixed costs of packaging, testing and shipping are spread across more product.

Why Starter Kits Cost More Per mg Than Refills

The gap between starter kits and refills isn't a pricing trick — it reflects what you're paying for the first time versus every time after. A starter kit's price has to cover the reusable injection pen, and in some cases a case and cooler pack, alongside the NAD+ cartridge itself. A refill, by contrast, is priced for the cartridge alone, because you already own the hardware (our guide to injection pen maintenance and troubleshooting covers how to get the most life out of it).

That's why it rarely makes sense to compare a refill's cost per mg directly against a starter kit's cost per mg as if they were the same product — they're priced to cover different things.

What Cost Per mg Doesn't Tell You

Cost per mg is a genuinely useful starting point, but it isn't the whole story. On its own, it says nothing about whether the NAD+ has been independently tested for purity, whether it's stored and shipped correctly on a cold chain, how reliably it's delivered in the UK, or what support you'd get if something went wrong with an order.

It's also worth being clear-eyed about where NAD+ injectable kits sit regulatorily. NAD+ kits sold in the UK, including ours, are not licensed medicines approved by the MHRA in the way a prescription drug is — a distinction covered in MHRA's own guidance on the supply of unlicensed medicinal products. The underlying science is also still developing: a recent peer-reviewed review of NAD+ biology and supplementation notes that injectable and intravenous NAD+ delivery is less well characterised than oral precursors, and that robust long-term clinical evidence is still limited. None of that makes cost per mg pointless — it just means it's one factor to weigh, not the whole decision.

Frequently Asked Questions

Does a higher cost per mg always mean worse value?

Not necessarily. Cost per mg is a useful starting point, but it doesn't capture everything that affects value — including third-party purity testing, UK cold-chain delivery, included hardware, and the support you get if you have questions. A kit with a slightly higher £/mg that's properly tested and reliably delivered can be worth more than the cheapest option on paper.

How do I know how many doses I'll actually get from one kit?

Compare the kit's total mg against the amount used per injection in your routine. A 1000mg cartridge used at a lower per-injection amount will stretch across more doses than the same cartridge used at a higher one, which changes your real cost per dose even when the cost per mg is identical. Always follow the dosing instructions supplied with your specific kit.

Do subscription refill plans really work out cheaper than one-off starter kits?

Often, yes — because a subscription usually prices the NAD+ cartridge alone, without the reusable pen, case or cooler pack you've already paid for once. As the comparison above shows, refill plans from both brands we checked came out cheaper per mg than their matching starter kits. Check the ongoing price, not just an introductory offer, before committing, and confirm you can pause or cancel easily.

Is it fair to compare the cost per mg of at-home injections with clinic IV drips?

Not directly. Clinic-administered IV NAD+ typically costs more per session partly because the price covers practitioner time, equipment and the infusion process itself, not just the NAD+ content. Comparing clinic IV cost per mg with at-home injection cost per mg is really comparing two different services, not just two prices for the same ingredient.

Why won't some sellers state how many mg are in their kits?

If a seller doesn't clearly publish the total mg of NAD+ in a kit, or the mg per dose, you can't calculate a genuine cost per mg or know what you're actually paying for. Reputable UK suppliers list this information on the product page — if you can't find it, it's reasonable to ask before you buy.
