All of our nasal sprays contain 30 servings per container. This is also true of all strengths of our NAD+, Glutathione, and Kanna nasal sprays.

Each bottle contains 10ml of solution, even though the bottle has a 15ml capacity. This is intentional and necessary to ensure proper function of the nasal spray pump. A small amount of extra space is required to maintain air pressure and deliver consistent sprays throughout the product’s use. Rest assured, you are receiving the full advertised amount of active formula in every bottle.

The best way to use a nasal spray is as follows:

1. Shake the Bottle – If required, gently shake the nasal spray bottle before use.
2. Prime the Spray (If Needed) – If it’s a new bottle or hasn’t been used in a while, pump it a few times until a fine mist appears.
3. Clear Your Nose – Gently blow your nose to remove any mucus and ensure better absorption.
4. Position the Bottle Correctly – Tilt your head slightly forward and insert the nozzle into one nostril while keeping the other nostril closed with your finger.
5. Breathe and Spray – While breathing in gently through your nose, press the pump to release the spray. Avoid sniffing too hard to prevent the mist from going straight into your throat.
6. Switch Nostrils – Repeat the process for the other nostril.
7. Wait Before Blowing Nose - We recommend waiting at least 60 seconds before blowing your nose again for optimal absorption. Tilting your head back slightly during this time will further increase absorption.
8. Avoid Contamination – Wipe the nozzle clean after each use and replace the cap securely. Do not share your nasal spray with others.

For best results, follow the specific instructions on your product label, as dosing and frequency may vary.

We offer multiple strengths of our NAD+ Nasal Spray to accommodate various budgets. While the bottle size remains the same, the amount per serving differs across options. We recommend the highest strength for optimal results, but we also offer lower-strength alternatives to ensure affordability for all customers. You can choose the option that best fits your wellness needs and budget.

All three strengths of our NAD+ Nasal Spray contain 30 servings.

Our NAD+ Nasal Sprays are stable at room temperature. However, we recommend for extended storage (more than 30 days) that they be refrigerated to maintain maximum potency.

While IVs are an effective way to raise NAD+ levels quickly, they only offer a short term solution, unless you go back for an infusion regularly.

By using a nasal spray daily, you can saturate your NAD+ levels over time,
and maintain saturation long term.

A nasal spray is also a less time consuming, and more convenient way to administer NAD+. IVs take between 4-8 hours (depending on the dosage, and application rate). Using a nasal spray takes just seconds daily.

We offer multiple strengths of our Glutathione Nasal Spray to accommodate various budgets. While the bottle size remains the same, the amount per serving differs across options. We recommend the highest strength for optimal results, but we also offer lower-strength alternatives to ensure affordability for all customers. You can choose the option that best fits your wellness needs and budget.
