NAD+ (nicotinamide adenine dinucleotide) is a coenzyme found in every living cell. Its main day job is helping your cells turn food into usable energy, and it's also involved in the cellular repair and "housekeeping" that keep you running well. Research suggests the body's NAD+ tends to decline as we age — which is a big part of why NAD+ has become such a focus in the energy and healthy-aging conversation.

Two seconds at the sink. Following the directions from your provider and the product label, you spray once into the nostril and breathe normally. No swallowing, no needles, no clinic visit. Most people fold it into a moment they already have — by the bathroom mirror in the morning or before bed — because consistency over weeks is what matters far more than any single dose.

NAD+ is notoriously hard to deliver in a usable form through a swallowed tablet — the gut breaks much of it down before it can be put to work. The nose, by contrast, is one of the body's most absorbent surfaces, with a rich blood supply designed for things to enter circulation quickly. The nasal spray is built specifically around that delivery advantage, with a licensed provider reviewing whether it's appropriate for you.

It's designed to feel like other nasal sprays you may have used — a quick, light mist with minimal sensation. Most people don't taste much; a faint background taste or a brief tingle is the most that's typically described. If you experience irritation, dryness, or anything unexpected, stop and reach out to your provider — they can adjust technique or look into alternatives.

It varies a lot from person to person. Some people describe a lift in energy and clarity within the first few weeks; for others it's more gradual. NAD+ support isn't a stimulant — there's no jolt-and-crash. It works by supporting systems your cells rely on, so changes tend to feel like a steady return of "more in the tank" rather than a spike. Consistency over weeks matters far more than any single application.

A licensed provider through ILSA reviews your information before anything is approved, to help confirm it's appropriate for you. As with anything you put in your body, individual responses differ, so share your full health history and any medications during your intake. If you're pregnant, nursing, managing a medical condition, or taking prescription medication, raise that with your provider. Use only as directed, and seek medical care for any serious or unexpected reaction.

Your monthly price covers the spray, the provider review, and discreet shipping — cash-pay, no insurance required, and no hidden fees or auto-renewal traps. There's no commitment until a provider approves you, and the details are clear before you ever pay.

It's available nationwide through the ILSA platform, subject to provider evaluation, eligibility, and the rules of your state. The fastest way to find out is to start the online visit — there's no charge or commitment until a provider reviews your information.
