How to Store and Reconstitute NAD+: A Step-by-Step Guide (2026)

> **Quick answer — does NAD+ need to be refrigerated?** **Yes.** Once NAD+ is reconstituted (mixed with bacteriostatic water), it must be stored in the refrigerator at 36–46°F (2–8°C). **What is NAD+'s shelf life?** Sealed lyophilized powder keeps **2+ years** when frozen, while reconstituted liquid NAD+ lasts about **28 days for full potency (up to 30–60 days refrigerated)**. Never freeze the mixed solution — freeze-thaw cycles degrade the molecule. ## NAD+ Storage and Reconstitution: Proper Handling for Maximum Potency Lyophilized NAD+ powder is stable at room temperature, but once reconstituted with bacteriostatic water, the solution degrades steadily — losing measurable potency within days if stored improperly. Correct reconstitution technique and storage conditions are essential to getting the dosage accuracy you are paying for. ## Storage Requirements: The Non-Negotiable Rules If your main question is simply whether NAD+ requires refrigeration, our quick-answer guide on [does NAD+ need to be refrigerated](/guides/does-nad-need-to-be-refrigerated-complete-storage-guide) covers the essentials. Below, we go deeper into the specifics for each form. ### Unreconstituted (Powder) NAD+ This is your NAD+ before you add bacteriostatic water. In powder form, NAD+ is relatively stable. - **Ideal storage:** Freezer at -4 to 36 degrees F (-20 to 2 degrees C) - **Keep it:** In original vial, away from light - **Shelf life:** 2+ years when properly frozen - **Key rule:** Do not repeatedly freeze and thaw. Take out the vial only when you are ready to reconstitute. ### Reconstituted (Liquid) NAD+ Once you add bacteriostatic water, the clock starts ticking. - **Ideal storage:** Refrigerator at 36-46 degrees F (2-8 degrees C) - **Do NOT freeze** the reconstituted solution -- freeze-thaw cycles damage the molecule - **Keep it:** In original vial, away from light, tightly sealed - **Shelf life:** 30-60 days refrigerated - **Label it:** Write the reconstitution date on the vial with a marker ## Reconstitution: Step by Step ### What You Need - NAD+ powder vial - Bacteriostatic water (BAC water) -- not sterile water, not saline - Sterile syringe (3-10mL depending on volume) - Alcohol swabs - Clean, flat workspace ### The Process **Step 1: Prepare your workspace.** Wash hands thoroughly. Wipe down the surface. Gather everything before opening anything. **Step 2: Calculate your water volume.** This determines your concentration. For a 500mg vial: | BAC Water Added | Concentration | Volume per 100mg Dose | |-----------------|---------------|-----------------------| | 2.5mL | 200mg/mL | 0.50mL | | 5.0mL | 100mg/mL | 1.00mL | | 10.0mL | 50mg/mL | 2.00mL | We typically recommend the 100mg/mL concentration. It is easy to calculate doses and keeps injection volumes reasonable. **Step 3: Clean the vial tops.** Wipe both the [NAD+ vial](/products/nad-001) and BAC water vial with alcohol swabs. Let them air dry for 15-30 seconds. **Step 4: Draw the BAC water.** Pull your calculated volume into a sterile syringe. **Step 5: Add water to the NAD+ vial.** Insert the needle through the rubber stopper and inject slowly down the inside wall of the vial. Do NOT spray directly onto the powder -- this creates foam and makes dissolution harder. **Step 6: Mix gently.** Swirl the vial in a circular motion. Roll it between your palms. Do NOT shake vigorously -- aggressive shaking can damage the molecule. If it does not dissolve immediately, set it down for a few minutes and try again. Complete dissolution can take up to 10-15 minutes. **Step 7: Inspect the solution.** It should be clear to slightly yellow. No particles floating. No cloudiness. **Step 8: Label and store.** Write the date and concentration on the vial. Place it in the refrigerator immediately. ## Signs Your NAD+ Has Degraded Discard your NAD+ if you observe any of the following: - **Cloudiness** -- Indicates protein aggregation or contamination - **Visible particles** -- Precipitates that should not be there - **Deep yellow or brown color** -- A slight yellow tint is normal, but darkening indicates breakdown - **Unusual stinging on injection** -- More discomfort than usual can signal degradation - **Past the 60-day mark** after reconstitution When in doubt, throw it out. A $200 vial is not worth an injection of degraded product. ## Temperature Excursion Rules Real life happens. You might forget to put the vial back after your morning injection, or your pharmacy shipment sits on the porch for a few hours. For detailed time limits at each temperature, see our guide on [how long NAD+ can safely stay out of the fridge](/guides/how-long-can-nad-be-out-of-the-fridge). Here is how to handle it: **Brief excursion (under 2 hours above 46 degrees F):** Usually still fine. Return to refrigeration immediately and note the event. **Extended excursion (2-6 hours above 46 degrees F):** Potency may be reduced. Consider the vial compromised if this happens more than once. **Prolonged room temperature (over 6 hours):** Discard. The degradation is likely significant enough to affect potency and safety. **General rule:** Room temperature storage (under 77 degrees F) should never exceed 24 hours total across the life of the reconstituted vial. ## Travel With NAD+ ### Short Trips (Under 24 Hours) - Insulated bag with a single ice pack - Separate the ice pack from the vial with a cloth (direct contact can freeze the solution) - Return to a refrigerator as soon as possible ### Longer Trips - Medical-grade cooler with multiple ice packs - Temperature monitoring strip if available - Use hotel refrigerator immediately upon arrival ### Air Travel - Carry in your cabin bag -- never check NAD+ in luggage (cargo holds are not temperature-controlled) - TSA allows medical liquids and syringes when declared - Bring your pharmacy label or prescription documentation ## Handling Best Practices Before each injection: 1. Remove the vial from the refrigerator 5-10 minutes before use (cold solution stings more) 2. Inspect the solution visually 3. Swirl gently -- do not shake 4. Wipe the rubber stopper with a fresh alcohol swab 5. Use a new needle every time -- never re-enter the vial with a used needle ## Quick Reference Table | State | Temperature | Maximum Duration | Container | |-------|-------------|-----------------|-----------| | Powder (unreconstituted) | Freezer (-20 to 2 degrees C) | 2+ years | Original sealed vial | | Reconstituted liquid | Refrigerator (2-8 degrees C) | 30-60 days | Original vial, labeled | | In transport | Insulated cooler with ice | Under 24 hours | Insulated bag | | Room temperature | Under 25 degrees C | Under 24 hours total | Emergency only | Proper storage is not complicated, but it is non-negotiable. NAD+ is an investment in your health -- protect that investment by handling it correctly. ## More NAD+ Storage Resources - **Wondering if your vial is still good after sitting out?** See [How Long Can NAD+ Be Out of the Fridge?](/guides/how-long-can-nad-be-out-of-the-fridge) for exact time and temperature thresholds. - **Need a quick yes/no on refrigeration?** Our guide on [Does NAD+ Need to Be Refrigerated?](/guides/does-nad-need-to-be-refrigerated-complete-storage-guide) gives the short answer plus a clinic SOP checklist. - **Ready to start your protocol?** Learn about [NAD+ injection benefits](/guides/nad-injection-benefits-anti-aging-energy-recovery-guide), [proper NAD+ dosage](/guides/nad-plus-dosing-guide-how-much-to-take), and [NAD+ side effects and safety](/guides/nad-side-effects-safety-what-to-expect). --- ## References - [Stability and degradation of nicotinamide adenine dinucleotide in various conditions](https://doi.org/10.1016/j.xphs.2019.06.015). *Journal of Pharmaceutical Sciences*, 2019. - [NAD+ intermediates: The biology and therapeutic potential of NMN and NR](https://doi.org/10.1016/j.cmet.2017.11.002). *Cell Metabolism*, 2018. - [USP General Chapter on Pharmaceutical Compounding - Sterile Preparations](https://www.usp.org/compounding/general-chapter-797). *United States Pharmacopeia*, 2022.
