Research overview based on the cited scientific literature.

• Goal: Support cellular energy metabolism, DNA repair pathways, and mitochondrial function through exogenous NAD+ supplementation[1].

• Storage: Lyophilized powder frozen at −20 °C (−4 °F); reconstituted solution refrigerated at 2–8 °C (35.6–46.4 °F) for up to 14 days; protect from light.

Proper storage is critical to preserve NAD+ stability and potency.
• Lyophilized (Unopened): Store at −20 °C (−4 °F) or below (ideally −80 °C for multiyear storage) in a dry, dark environment[6]. Minimize moisture exposure as NAD+ powder is hygroscopic.
• Reconstituted Solution: Refrigerate at 2–8 °C (35.6–46.4 °F) and use within approximately 14 days[7]. Keep protected from light (UV exposure degrades NAD+).
• Avoid Freeze–Thaw Cycles: Do not repeatedly freeze and thaw reconstituted NAD+ solution, as this reduces potency.
• Inspection: Before each use, inspect the solution for clarity. A fresh NAD+ solution should be clear and colorless. Discard if discoloration, cloudiness, or precipitate develops.

NAD+ is a coenzyme central to redox reactions, energy metabolism (glycolysis, TCA cycle, oxidative phosphorylation), and cellular maintenance pathways including DNA repair and mitochondrial biogenesis[1]. Cellular NAD+ levels decline with age and metabolic stress, which may contribute to reduced mitochondrial function and impaired cellular resilience[8].
Clinical research on NAD+ therapy has primarily used intravenous infusions at high doses (500–1,000 mg) for applications such as addiction treatment and acute metabolic support[2][9]. A pilot metabolic study demonstrated that a 750 mg NAD+ IV infusion over 6 hours was welltolerated in humans, with rapid metabolic clearance and no acute toxicity[10]. However, IV administration requires clinical supervision and specialized equipment.
Subcutaneous (SC) or intramuscular (IM) injections at lower doses (tens to low hundreds of milligrams) are emerging as practical alternatives for maintenance therapy and wellness applications[3][11]. Compounded NAD+ can be administered SC in small volumes, and SC selfinjection is convenient for ongoing use[12].

Observations from preclinical models and clinical case reports.
Potential Benefits (Reported in Literature)
• May support cellular energy production and mitochondrial function through replenishment of NAD+ pools[1][8].
• Human case reports and pilot studies suggest benefits at 100–300 mg/day ranges for cognitive support and metabolic health[13].
• Highdose IV protocols (500–1,500 mg daily for ~10 days) have been used in openlabel studies for substance use disorder, with reports of reduced cravings and improved mood in followups[2][9].
• No severe adverse events have been reported in published NAD+/NADH trials; side effects are generally mild[14].
Potential Side Effects
• High doses can produce adverse reactions such as insomnia, anxiety, or fatigue if escalated too quickly; gradual titration is advised[4].
• Mild injectionsite reactions (redness, itching, soreness) may occur with subcutaneous administration; typically resolve with site rotation.
• Some individuals report transient headache or flushing; these effects are generally dosedependent.
• Doses exceeding ~200–300 mg/day should generally be reserved for supervised therapeutic use due to potential for metabolic byproduct accumulation[15].
