Understand what NAD+ is, compare the two pen strengths and find the current product, quality and safety information. NAD.Power keeps the science, the device instructions and the purchase decision clearly separated.
NAD+ (nicotinamide adenine dinucleotide) is a coenzyme involved in normal cellular metabolism and enzyme reactions. Research on NAD biology does not by itself establish the effects of a particular commercial product or delivery format. Our guides keep those evidence levels distinct.
Three questions worth asking before interpreting a study or comparing product formats.
NAD+ participates in redox reactions and serves as a substrate for enzymes involved in cellular processes. NADH is its reduced partner, while NMN and NR are different molecules involved in NAD metabolism. Basic biology is important context, but it is not proof of a specific wellness outcome.
NAD measurements vary by tissue, population, analytical method and study design. A change in a blood or tissue marker is not automatically an improvement in how a person feels or functions. Read the participants, route, comparator and endpoints before applying a finding to any product.
IV, subcutaneous and oral products differ in administration, formulation and evidence. A study of one route or ingredient cannot be transferred directly to another. Our comparison guide explains format and convenience without promising equivalent blood levels or health outcomes.

Understand the product information, find the official instructions, check quality documents and review safety before choosing your next step.
A printable checklist for product research, arrival, quality, storage and support.
Open the Starter Guide → 02Kit orientation, official instruction checkpoints and where to pause and ask for help.
Read How to Use → 03Match documents to products and understand what each test does and does not establish.
Explore quality information → 04Storage, handling, disposal, travel and product-concern guidance.
Review safety guidance →Compare the total NAD+ content, format and price. Use the supplied product leaflet for product-specific instructions.
The lower total NAD+ content per pen.
The higher total NAD+ content per pen.
The difference is total NAD+ content and price per milligram. Product-specific use belongs to the current supplied instructions, not a generic schedule.
| 500 mg | Best value 1000 mg | |
|---|---|---|
| NAD+ per pen | 500 mg | 1000 mg |
| Pre-filled cartridge | 3 ml | 3 ml |
| Product format | Pre-filled pen | Pre-filled pen |
| Price | €200 | €300 |
| Price per mg | €0.40 | €0.30 — 25% less |
| Key distinction | Lower total NAD+ content per pen. | Higher total content and lower price per mg. |
Match the product, variant, label and any quality document. If anything is unclear or inconsistent, pause and contact support.
Use the current instructions supplied with your exact product. Do not replace them with a routine from a forum, social post or another device.
Follow the current storage guidance and use an appropriate local sharps route for used needles. Never share a pen between people.
A pre-filled NAD+ pen in a choice of 500 mg or 1000 mg. Review the current kit contents and supplied instructions before use.
NAD.Power is a pre-filled pen containing nicotinamide adenine dinucleotide (NAD+), available in two total strengths: 500 mg and 1000 mg.
The website provides product and educational information, not diagnosis, treatment or individual medical advice. If you are pregnant, breastfeeding, under 18, taking medication or managing a health condition, speak with a qualified healthcare professional before using the product.
The formats differ in administration, formulation, cost, convenience and available evidence. IV, subcutaneous and oral routes should not be treated as interchangeable, and a study of NAD+, NMN or NR in one format cannot be transferred directly to another.
Our format comparison separates practical differences from scientific evidence and does not use a blood-marker change as a promised health outcome.
The current leaflet supplied with your exact product is the primary source for device preparation and use. Our How to Use guide helps you check the kit and find the official instruction path; it does not replace that leaflet.
If a component, label or step is unclear, pause and contact support rather than improvising. Never share a pen between people.
Follow the current product-specific leaflet supplied with your pen. We do not publish a generic loading phase, maintenance schedule, cycle or titration protocol because those decisions require verified product information and individual context.
The 500 mg and 1000 mg labels describe total NAD+ content per pen, not a recommended dose. For individual health questions, consult a qualified healthcare professional.
Every order ships cold-chain compliant: insulated mailer with phase-change gel packs that hold 2–8°C for 72+ hours. Outer packaging is plain — no clinical branding, no NAD references on the label.
Full zone rates are on the Shipping & Returns page.
Unopened pens: yes. EU consumer law gives you a 14-day right of withdrawal from delivery — no reason needed, full refund within 14 days of the returned parcel reaching us.
Opened pens: non-returnable for sterility reasons (Article 16(e) of EU Consumer Rights Directive 2011/83 explicitly exempts sealed health products once unsealed).
If your parcel arrives damaged or thermally compromised: photograph the package and the cold-pack indicator inside, email us within 48h, and we ship a replacement at our cost — no return required.
Card (NiftiPay) — Visa, Mastercard and other major cards, processed securely by our payment partner. You get 5% off automatically when you pay by card; the discount appears in your order total at checkout. We never see or store your card details.
Bank transfer (SEPA / SWIFT) — you receive our bank details with the order confirmation. Your order is prepared as soon as the payment arrives: SEPA usually lands in 1 business day, SWIFT in 2–4. There is no card discount on bank transfers.
Yes — worldwide with FedEx International Priority. Bulgaria 1–2 business days, EU 2–5, UK/Switzerland/Norway 2–5, USA & Canada 3–6, rest of the world 3–7. Exact zone rates are on the Shipping & Returns page.
Customs: intra-EU orders are duty-free — the price at checkout is final. Outside the EU, your customs authority may collect import duties or taxes on arrival; these are set by your country, are not included in our prices, and are payable by the recipient. US orders under $800 generally clear duty-free (de minimis). Checkout warns you automatically if you select a non-EU country.
Available destinations, shipping rates and any customs information are shown on the Shipping & Returns page and at checkout. Import rules can differ by destination and may change.
Check the requirements that apply to you before ordering. We reserve the right to cancel and refund orders to destinations we cannot serve.
Follow the current storage instructions on your product label and supplied leaflet. Our Safety & Storage guide explains the general checks, but does not replace product-specific instructions.
If the product has been exposed to an uncertain temperature, do not assume that it is either safe or ruined. Record the approximate conditions and duration, then contact support with the product or batch identifier.
Match the document to the exact product and batch, then read the tested material, methods, specifications, results, dates and laboratory together. A result for an ingredient or bulk solution does not automatically establish every attribute of a finished pen.
Use our Quality & Testing guide and COA guide for the full checklist. If a current batch document is unavailable or unclear, contact support before ordering or using the product.
Check the current kit list on the product information supplied with your order. At a minimum, identify the NAD.Power pen in the selected 500 mg or 1000 mg variant, the supplied components and the current product leaflet.
On arrival, check that the product name, variant, packaging, label and components agree with your order and the current kit list. If anything is missing or inconsistent, pause and contact support with your order number and a clear photograph.
