Understanding NAD+ Therapy: Benefits, Risks, and What the Evidence Actually Says

​Nicotinamide Adenine Dinucleotide (NAD+) is a essential coenzyme found in every cell of your body. It plays a critical role in mitochondrial energy production, cellular repair, and metabolic health. While NAD+ levels naturally decline as we age, the growing popularity of injectable NAD+ therapy has sparked significant debate. Here is what you need to know about the science, safety, and baseline testing before considering treatment.

​What the Science Says

​While the biological importance of NAD+ is undeniable, the delivery method matters immensely when evaluating its effectiveness.

• ​Injectable NAD+: Human clinical trials evaluating subcutaneous or intramuscular NAD+ injections remain very limited. Much of the enthusiasm stems from animal models or anecdotal claims rather than robust human data.

• ​Oral Precursors: The strongest human clinical evidence currently supports oral NAD+ precursors—such as Nicotinamide Mononucleotide (NMN) and Nicotinamide Riboside (NR)—rather than direct injections.

• ​FDA Status: NAD+ injections are not FDA-approved to treat, prevent, or cure any medical condition. Because these are typically obtained through compounding pharmacies, product quality and purity can vary, and several compounded versions have faced regulatory recalls.

​Potential Side Effects and Safety Considerations

​While most reported side effects are mild—such as temporary nausea, headaches, fatigue, or localized injection site soreness—theoretical risks require careful consideration. Accelerating cellular metabolism can put extra stress on organ systems, and ongoing research is evaluating the long-term impacts of elevated NAD+ on existing tumor growth or cancer risk.

​Essential Baseline Lab Work

​Before starting any NAD+ protocol, a healthcare provider should evaluate your baseline organ function and overall systemic health. Essential lab panels include:
