What Is NAD+ IV Therapy? Benefits, Science & What to Expect in Costa Rica
NAD+ (Nicotinamide Adenine Dinucleotide) is one of the most important coenzymes in the human body — essential for energy production, DNA repair, and cellular health. Yet as we age, NAD+ levels decline significantly, contributing to fatigue, cognitive decline, and accelerated aging.
NAD+ IV therapy delivers this coenzyme directly into the bloodstream, bypassing the digestive system for immediate cellular availability. At Rejuvilife in Escazú, Costa Rica, NAD+ IV therapy is one of our most requested treatments by both local and international patients seeking to optimize energy, mental clarity, and long-term health.
What Is NAD+ and Why Does It Matter?
NAD+ is present in every cell of the body and plays a central role in two fundamental biological processes:
Energy metabolism — NAD+ is a critical cofactor in the conversion of nutrients into ATP, the primary energy currency of cells. Without sufficient NAD+, mitochondria cannot produce energy efficiently.
DNA repair and cellular maintenance — NAD+ activates sirtuins, a family of proteins involved in DNA repair, inflammation regulation, and cellular longevity. Research suggests that maintaining healthy NAD+ levels supports healthier aging at the cellular level.
NAD+ levels naturally decline by approximately 50% between the ages of 40 and 60. This decline is associated with reduced energy, cognitive changes, slower recovery, and increased vulnerability to age-related conditions.
Benefits of NAD+ IV Therapy
When administered intravenously at therapeutic doses, NAD+ IV therapy may support:
Energy and vitality
Improved mitochondrial efficiency means cells produce energy more effectively. Many patients report noticeable improvements in physical and mental energy within days of their first sessions.
Cognitive function
NAD+ supports neuronal health and may improve mental clarity, focus, and memory. It is increasingly used in longevity protocols targeting cognitive performance and brain health.
Cellular repair and anti-aging
By activating sirtuin pathways, NAD+ IV therapy may support DNA repair mechanisms, reduce oxidative stress, and promote healthier cellular aging.
Metabolic health
NAD+ plays a role in insulin sensitivity and metabolic regulation. Optimizing NAD+ levels may support healthy body composition and metabolic efficiency.
Recovery and physical performance
Athletes and physically active patients use NAD+ IV therapy to support faster recovery, reduce inflammation, and maintain peak physical performance.
How NAD+ IV Therapy Works at Rejuvilife
At Rejuvilife in Escazú, Costa Rica, NAD+ IV therapy is administered under the direct supervision of Dr. Alan Inman, a physician specialized in anti-aging and regenerative medicine.
The process:
1. Medical consultation — Dr. Inman reviews your health history, symptoms, and goals to determine the appropriate NAD+ dose and protocol.
2. IV infusion — NAD+ is administered slowly through an intravenous drip. Sessions typically last between 2 and 4 hours depending on the dose. The slow infusion rate is important for comfort and safety.
3. Personalized protocol — Most patients begin with a series of 3 to 5 sessions over one to two weeks, followed by maintenance infusions as needed.
4. Combination therapy — NAD+ is frequently combined with other treatments at Rejuvilife, including Hyperbaric Oxygen Therapy, Glutathione IV, and hormone optimization for enhanced results.
What to Expect During a Session
NAD+ IV therapy is well tolerated by most patients. During the infusion, some individuals experience mild sensations such as warmth, tingling, or a temporary feeling of chest tightness — all of which resolve when the infusion rate is slowed. Dr. Inman's team monitors each patient throughout the session.
After the infusion, many patients report feeling energized and mentally clear. Results typically build over a series of sessions.
