What is Longevity & Cellular Health Therapy?

Longevity medicine focuses on optimizing cellular function to support healthy aging and vitality. NAD+ (nicotinamide adenine dinucleotide) is a coenzyme essential for cellular energy production, DNA repair, and metabolic function. Research shows NAD+ levels decline significantly with age, contributing to cellular dysfunction and age-related health changes.

Our clinician-supervised NAD+ therapy programs aim to restore optimal cellular function through direct supplementation. We offer multiple delivery methods to match your lifestyle and preferences, from weekly injections for maximum bioavailability to daily nasal spray for convenience.

In addition to NAD+ therapy, we offer Sermorelin, a growth hormone-releasing peptide that supports natural hormone production. This therapy may help with body composition, recovery, sleep quality, and overall vitality. All treatments are individually reviewed by our medical team to ensure safety and appropriateness.

Frequently Asked Questions

What is NAD+ and why is it important?

NAD+ is a coenzyme found in every living cell, essential for cellular energy production, DNA repair, and metabolic function. Research shows NAD+ levels decline approximately 50% from youth to middle age, which may contribute to reduced energy, slower recovery, and accelerated cellular aging.

How do I choose between injectable and needle-free NAD+ delivery?

Injectable NAD+ offers higher bioavailability (85-95%) but requires weekly self-injections. Nasal spray offers daily convenience with 60-70% bioavailability. Both deliver clinician-prescribed NAD+ therapy. Your provider can help you choose based on your lifestyle, comfort with injections, and treatment goals.

How long until I see results from NAD+ therapy?

Many patients report increased energy and improved sleep within 1-2 weeks of starting therapy. More significant benefits related to cellular health and longevity are typically observed over several months of consistent use.

What is Sermorelin and how does it differ from NAD+?

Sermorelin is a growth hormone-releasing peptide that stimulates your pituitary gland to produce growth hormone naturally. While NAD+ focuses on cellular energy and repair, Sermorelin supports body composition, recovery, and vitality through growth hormone optimization. Many patients use both therapies together.

Are these longevity treatments safe?

Our longevity therapies have been studied extensively and have favorable safety profiles when used as prescribed. Our medical team reviews your complete health history to ensure safety. Side effects are typically mild, such as injection site redness or temporary flushing.

Is longevity therapy covered by insurance?

Longevity and cellular health therapies are typically not covered by insurance as they are considered preventive or wellness care. We offer affordable self-pay pricing to make these treatments accessible.
