One of the most common questions we get isn't "does NAD+ work" — it's "which one should I actually buy?" With three different formats on offer, it's worth understanding what sets them apart before you decide.
There's no universally "best" option here. The right format really comes down to your lifestyle, your comfort with needles, and how much control you want over your dose.
How Each Format Gets NAD+ Into Your System
SmartStrip+ (Oral Strips)
These dissolve under your tongue, so the NAD+ absorbs through the soft tissue in your mouth rather than passing through your digestive system. That's what makes them faster-acting than a typical pill or capsule, without needing a needle at all.
NADpulse+ Pen
A pre-filled, reusable injector that delivers NAD+ directly into the body via a small subcutaneous injection. Because it bypasses digestion entirely, it tends to get NAD+ into your system efficiently and consistently.
Nad+Prime Vials
A liquid NAD+ concentrate drawn up and injected manually. This format gives you the most flexibility over dosage, since you control exactly how much you draw each time.
Comparing Absorption Speed
- Fastest to act: Both the pen and vials, since injectable NAD+ skips the digestive process altogether
- Quick but slightly more gradual: SmartStrip+, which still avoids digestion by absorbing through the mouth, but tends to release a touch more gently than an injection
If speed is your main priority, injectable formats (pen or vials) generally have the edge. If you'd rather avoid needles altogether, the strips are still a needle-free way to bypass your gut.
Comparing Convenience
- Most convenient for travel and on-the-go use: SmartStrip+ — no fridge required for short periods, no needles, no prep
- Most convenient for a simple, repeatable routine: NADpulse+ Pen — it's pre-filled and ready to dose with minimal setup once you're used to it
- Most convenient if you like full control: Nad+Prime Vials — ideal if you're comfortable with injections and want to manage your own dosing precisely
Think about where and when you'll actually be taking it. A strip slipped into a gym bag or carry-on is a different commitment to a vial that needs to stay refrigerated.
Comparing Dosage Control
- Vials offer the most precise, adjustable dosing — you decide exactly how many mg per use
- The pen offers consistent, pre-set dosing each time, which suits people who'd rather not measure anything themselves
- Strips come in fixed doses per strip, making them the simplest to use without any calculation at all
If you like fine-tuning your routine, vials give you that flexibility. If you'd rather something foolproof, the pen or strips take the guesswork out entirely.
Which One Fits You?
- Always on the move, hate needles, want something simple: SmartStrip+
- Want injectable NAD+ without the hassle of drawing up doses yourself: NADpulse+ Pen
- Want full control over your dosage and don't mind manual injections: Nad+Prime Vials
- Want the best of both worlds: Some people keep strips for travel days and pens or vials for their main at-home routine
There's nothing wrong with mixing formats either — plenty of people use strips when they're out and about, then switch to injections for their regular routine at home.
The Bottom Line
All three formats deliver the same core ingredient — pharma-grade NAD+ — just through different routes. Strips suit convenience and a needle-free lifestyle, the pen suits anyone who wants straightforward injectable dosing, and vials suit those who want full control over how much they take.
The "right" choice isn't about which is objectively superior — it's about which one you'll actually use consistently. Pick the format that fits naturally into your routine, and let consistency do the rest.
