NAD+ gets talked about a lot in longevity circles, but the explanations tend to be either too technical to be useful or too vague to be believable. This is the version that cuts through both problems: what NAD+ actually is, what it does in the body, why it declines with age, and what getting started through a telehealth provider actually looks like.
What NAD+ Is
NAD+ (nicotinamide adenine dinucleotide) is a coenzyme found in every cell in the body. It plays a central role in cellular energy production, DNA repair, and the regulation of proteins involved in aging and metabolic function. Without adequate NAD+, cells can’t produce energy efficiently, DNA damage accumulates faster, and the biological processes associated with healthy aging slow down.
NAD+ levels decline significantly with age. By middle age, most people have roughly half the NAD+ levels they had in their 20s. The effects of this decline — slower metabolism, reduced energy, impaired cellular repair, and cognitive changes — are now understood to be partly driven by this drop in NAD+.
What NAD+ Does
The research on NAD+ centers on several key functions:
- Energy production: NAD+ is essential to the mitochondrial processes that convert food into cellular energy (ATP). Low NAD+ means less efficient energy production.
- DNA repair: NAD+ activates sirtuins and PARP enzymes involved in detecting and repairing DNA damage. This is one of the primary mechanisms through which NAD+ is studied in the context of healthy aging.
- Metabolism: NAD+ plays a role in how cells respond to insulin and how efficiently they process glucose and fatty acids.
- Cognitive function: Brain cells are among the most energy-intensive in the body. NAD+ supports neuronal energy production and the repair processes that maintain cognitive function over time.
How to Get NAD+ Therapy
There are two main delivery methods: IV infusion at a clinic and subcutaneous injection at home. IV delivers a higher single-session dose. Subcutaneous injection is self-administered at home on a consistent schedule and is the more practical option for ongoing maintenance. Here’s a full comparison of both approaches.
Both ShedRX and GobyMeds offer NAD+ therapy through telehealth, with subcutaneous injection as the standard protocol.
ShedRX NAD+
ShedRX offers NAD+ therapy as part of their telehealth wellness platform alongside GLP-1 microdosing. Subcutaneous injection protocol shipped monthly from a licensed compounding pharmacy.

GobyMeds — All-in-One Platform
GobyMeds covers NAD+, GLP-1, and Sermorelin through a single registration. If you’re considering stacking therapies, this is the more versatile option. Use code MTVN25 for $25 off your first order.
Who NAD+ Therapy Is Most Useful For
The people who tend to see the most benefit from NAD+ therapy share some common characteristics: they’re over 40, they’re active and health-conscious, they’re already doing the fundamentals well (sleep, nutrition, exercise), and they’re looking for the next layer of optimization. NAD+ isn’t a substitute for the basics. It’s what you add when the basics are already in place and you want to address cellular function more directly.
It also stacks well with GLP-1 and sermorelin therapy. Each works on different systems. GLP-1 handles appetite and metabolic function. Sermorelin handles growth hormone and recovery. NAD+ handles cellular energy and repair. They don’t interfere with each other, and addressing all three creates a more complete picture of metabolic and longevity health.

Frequently Asked Questions
What should I know about nad+ therapy?
The most important factors to consider are effectiveness, safety, and how well it fits your specific situation. Research shows results vary based on individual health status and consistency of use.
How long does it take to see results?
Most people report noticing initial changes within 4-8 weeks when following recommended guidelines consistently. Significant results typically require 3-6 months of sustained effort.
Are there any important precautions?
Always consult with a healthcare provider before starting any new supplement or program, especially if you have existing health conditions or take medications.
