Is NAD+ Complete Nasal Spray the Right Formula for You?
You're Already Taking an NAD+ Booster
Many users add NAD+ Complete Nasal Spray to their existing routine for its targeted effects and fast uptake.
You're Not Sure Which NAD+ Booster to Take
There are a lot of competing claims saying one NAD+ booster is better than another. NAD+ Complete includes NMN, NR, trigonelline, and NAD+ itself, because the research is still developing, and no single precursor has been established as best. The nasal spray delivers all four.
You Want 4-in-1 Convenience
Four studied NAD+ boosters in two sprays. No stack to build, nothing to swallow, no water needed.

3 NAD+ Boosters,
Novel Delivery System

The same three NAD+ boosters as our capsules,
in a format that skips digestion entirely.

Cellular Energy

NAD+ is used by every living cell to turn the food you eat into usable energy. Increasing your NAD+ supply supports the processes behind generating sustained energy to power your days.†

Repair and Recovery

Your cells are constantly repairing and replacing what everyday stressors can deplete. NAD+ is vital to the processes of repair and recovery.†

Healthy Aging

NAD+ is involved in hundreds of biochemical functions, from metabolism to maintaining cellular health. Increased NAD+ levels can support the systems that keep you resilient over time.†

Science & Quality You Can Feel Good About

Every formula is built on established and emerging research and manufactured under pharmaceutical-grade standards, so healthy aging doesn't require a leap of faith.

Ingredient Purity

Our R&D team works hard to source the highest-quality, purest ingredients. Our products are non-GMO and we strive to keep them free of additives and fillers.

Liposomal Delivery

Our liposomal technology encapsulates fragile active ingredients in protective phospholipids. In our nasal spray, that encapsulation helps the actives absorb through the nasal membranes.

Third-Party Tested

Our products are tested in ISO- and cGMP-certified labs to ensure quality, purity, and potency. Certificates of Analysis (COAs) for the exact product you purchased are published on our website; simply use the batch number located on the bottom of your product to match it to your COA.

Made in the USA

All products are manufactured in the United States. We're committed to ensuring the highest-quality production standards, and our manufacturers maintain strict quality controls throughout the production process, from raw material sourcing to final bottling.

FAQ

Why four NAD+ boosters instead of one?

There's no consensus that one is best. NMN, NR, and trigonelline are precursors your body converts to NAD+, and NAD+ itself is included directly. Rather than betting on one, this formula covers all four.

How is this different from taking NMN or NR on its own?

Single-ingredient products give you one booster and let you control that dose precisely. NAD+ Complete Nasal Spray gives you broader coverage in two sprays. Many users take both.

Why are the amounts less than in the other formats?

Nasal delivery works differently from oral formats. The actives absorb through the nasal membranes rather than passing through digestion, so the serving is formulated for that route rather than scaled from a capsule or powder.

How do I use it?

Shake well, then spray into each nostril.

Do I need to take TMG with this?

Processing NAD+ precursors draws on your body's supply of methyl groups, which are also used in other biochemical functions. TMG (trimethylglycine) is a source of methyl groups, and some people take it alongside an NAD+ routine for that reason. Worth discussing with your healthcare provider.

When should I take it?

We generally recommend taking NAD+ boosters in the morning to align with your circadian rhythm. That said, many users keep NAD+ Complete Nasal Spray on hand for whenever it fits their day.

Can I take this with my other Renue by Science supplements?

Yes. NAD+ Complete Nasal Spray sits in the Boost pathway and is built to work alongside Protect, Optimize, and Regenerate formulas, and can be taken with other Renue Boost formulas, too.

How do I know what's actually in the bottle?

Every batch is third-party tested in ISO- and cGMP-certified labs, and the Certificate of Analysis is published on our site. Match the batch number on the bottom of your bottle to its COA.

    It's good stuff 👍

    I'll tell you I had already started NMNs and that makes an incredible difference with my system. I think this is more impactful but I'm not convinced it's not psychosomatic. I like it and fully recommend trying it for sure.

    Triple therapy seems to work

    I have used NAD+ spray, NMN, and NR for several months. My hair grows faster & looks better. This was noted in a recent study in Japan. Andrew Huberman also has noticed this. My energy level is excellent.

    I like to combine the nasal spray with my regular nad+ in pill form to ensure delivery

    I like to combine the nasal spray with my regular nad+ in pill form to ensure delivery. I definitely feel the difference when I combine the delivery with pill and then nasal spray to insure total intake
