Advanced sublingual delivery for superior absorption, faster energy, and measurable cellular repair — designed by HUM2N’s clinical experts.
- Boosts energy & vitality
- Supports cellular function
- Enhances focus & recovery
Dosage:
Suggested use:
Every human cell relies on NAD+ to fuel energy, repair DNA, and sustain healthy function. As NAD+ levels decline with age, so does our ability to recover, focus, and perform.
HUM2N Sublingual NAD+ restores these essential levels through a clinically engineered sublingual wafer — for rapid absorption and superior results you can feel.
- Rapid Disintegration: Dissolves in under 60 seconds.
- High Absorption: Directly into bloodstream — no gut loss.
- Clinically Proven: Supports measurable NAD+ increases.
- Feel It Faster: Sustained energy & clarity within 2 weeks.
Significantly increases blood NAD+ concentration within weeks.
Sublingual NAD+ users showed:
+59% NAD+ increase after 2 weeks and +76% after 6 weeks.
Formulated for superior sublingual absorption, HUM2N Sublingual NAD+ delivers NAD+ directly where it’s needed — bypassing digestive degradation.

HUM2N APPROACH
HUM2N Sublingual NAD+ uses an advanced sublingual delivery matrix designed for rapid dissolution and optimal bioavailability. This direct route bypasses the digestive tract, ensuring NAD+ reaches the bloodstream intact for faster, more effective results.
NAD+ (Nicotinamide Adenine Dinucleotide) is a coenzyme essential for energy production, DNA repair, and cellular communication. As levels drop with age, energy declines and recovery slows. Restoring your NAD+ levels is key to longevity, vitality, and sustained performance.
Sublingual NAD+ users showed: +59% NAD+ increase after 2 weeks and +76% after 6 weeks. Formulated for superior sublingual absorption, HUM2N Sublingual NAD+ delivers NAD+ directly where it’s needed — bypassing digestive degradation.
Storage:
Keep refrigerated. Protect from light & moisture.
Precautions:
Do not take if pregnant, breastfeeding, trying to conceive, or under 18. Consult your physician if you have any medical conditions.

Your Questions, Answered
Frequently asked questions
How long does it take to feel results?
Most users report noticeable improvements in energy, mental clarity, and overall vitality within the first 7–14 days of consistent use. Some experience benefits sooner, particularly around focus and workout recovery. As with all cellular therapies, response time varies based on baseline NAD+ levels, lifestyle, and individual biochemistry.
How is HUM2N Sublingual NAD+ absorbed?
HUM2N Sublingual NAD+ is absorbed sublingually, meaning it dissolves under the tongue and enters the bloodstream directly. This route bypasses the digestive system, reducing degradation and enabling faster systemic availability compared to traditional oral supplements.
Does NAD+ actually enter cells?
Yes. Pharmacokinetic data indicates that NAD+ delivered sublingually can enter circulation and be taken up by cells via established transport mechanisms, including connexin hemichannels and solute carrier pathways. This direct delivery supports meaningful increases in intracellular NAD+ availability.
How is this different from NMN or NR supplements?
NMN and NR are precursors — they must first be converted by the body into NAD+. HUM2N Sublingual NAD+ delivers NAD+ itself, eliminating reliance on conversion efficiency. For many individuals, this allows for faster, more predictable restoration of NAD+ levels.
How does Sublingual NAD+ compare to IV or injectable NAD+?
IV and injectable NAD+ deliver higher doses but require medical supervision and can cause side effects such as flushing, headaches, or palpitations. HUM2N Sublingual NAD+ offers a non-invasive, clinically engineered alternative designed for regular use — delivering meaningful NAD+ support without needles, downtime, or clinic visits.
Can I take Sublingual NAD+ alongside other supplements?
Yes. HUM2N Sublingual NAD+ is generally compatible with most supplement protocols. If you are taking prescription medications or have an underlying medical condition, we recommend consulting your healthcare professional before starting.
Can I travel without refrigeration?
Yes. Sublingual NAD+ can remain unrefrigerated for short periods, such as during travel. If refrigeration is not possible, we recommend consuming the product within 30 days. For long-term storage and maximum stability, refrigeration is advised.
What if a wafer cracks or breaks?
This will not affect efficacy. HUM2N Sublingual NAD+ wafers are intentionally delicate due to their highly porous, rapid-dissolution structure. A cracked or broken wafer delivers the same dose and benefits when used as directed.
Is it suitable for vegetarians or vegans?
Yes. HUM2N Sublingual NAD+ is vegetarian, gluten-free, and free from unnecessary fillers.
Is HUM2N Sublingual NAD+ clinically tested?
Yes. The formulation and delivery system have been clinically evaluated, with data demonstrating significant increases in blood NAD+ levels within weeks when used as directed.
