NAD+ Therapy

Physician-prescribed NAD+ therapy, a coenzyme involved in cellular energy production and DNA repair that declines with age. Used at PHI to support energy, cognitive clarity, and longevity-oriented care. The mechanistic rationale is strong and clinical evidence is accumulating; PHI is honest that benefits vary by patient. Delivered in a clinic setting, formulated to your situation rather than a fixed menu.

AT A GLANCE

NAD+ Therapy at PHI is administered by board-certified physicians Dr. Faisal Lalani and Dr. Nadiv Samimi at our Beverly Hills practice. PHI offers physician-supervised NAD+ in five tiered protocols, two intramuscular shots and three IV infusions, for cellular energy, DNA repair, and longevity, with doses progressed as tolerance is established.

What NAD+ Is

Nicotinamide adenine dinucleotide (NAD+) is a coenzyme found in every cell of the body. It plays an essential role in three areas of cellular function: energy production through mitochondrial metabolism, DNA repair, and longevity signaling through pathways involving sirtuins and other regulatory proteins.

NAD+ levels decline naturally with age. By age 50, cellular NAD+ levels are estimated to be roughly half of what they were in youth. This decline is associated with reduced cellular energy, impaired DNA repair, and increased markers of biological aging.

NAD+ therapy supplements the body’s NAD+ pool through direct administration. Unlike oral NAD+ precursors (NMN, NR), which must be converted by the body, IV and IM NAD+ delivers the molecule itself in usable form.

How PHI Approaches NAD+ Therapy

NAD+ therapy at PHI is physician-prescribed, not menu-selected. PHI’s approach starts with consultation to determine whether NAD+ therapy fits your specific goals and which protocol is appropriate.

The reason this matters: NAD+ therapy at meaningful therapeutic doses can produce side effects (chest pressure, flushing, nausea) particularly during initial infusions, and tolerance varies significantly by individual. PHI’s protocols are tiered intentionally, starting at lower doses for new patients and progressing only as tolerance is established.

Patients who would benefit more from a different intervention are told so. NAD+ is a powerful tool when it fits, but it is not the right answer for every patient pursuing wellness or longevity goals.

PHI’s NAD+ Protocols and Pricing

NAD+ therapy cost in Beverly Hills varies by protocol. PHI publishes pricing for transparency, with five tiered options designed for therapeutic initiation, ongoing optimization, and maintenance.

Intramuscular NAD+ shots

IM injections offer a practical, time-efficient option for sustaining NAD+ levels between IV sessions, ideal for patients on active optimization protocols.

NAD+ Shot 50 mg | $95 (first-timer, intramuscular). An ideal introduction to NAD+ therapy, delivered intramuscularly for rapid uptake with minimal time commitment.

NAD+ Shot 100 mg | $170 (regular user, intramuscular). Recommended for established NAD+ users maintaining levels between IV infusion sessions.

Intravenous NAD+ infusions

IV delivery provides complete bioavailability and systemic distribution. All IV protocols include 500 mL of hydration and electrolytes.

NAD+ IV Lite 250 mg | $400 (first-timer, up to 2 hours). The recommended starting point for IV therapy, allowing tolerance assessment at a therapeutic dose before progressing to higher concentrations.

NAD+ IV Plus 500 mg | $700 (regular use, up to 4 hours, recommended). PHI’s standard therapeutic protocol for ongoing optimization, energy restoration, and cellular repair, and the most-prescribed protocol for established patients.

NAD+ IV Ultra 1,000 mg | $1,000 (experienced, up to 6 hours). Reserved for experienced patients seeking maximum cellular replenishment and longevity benefit, appropriate only after lower-tier tolerance is established.

Choosing the Right Protocol

  • New to NAD+ therapy: most patients begin with a 50 mg IM shot or the IV Lite (250 mg) to assess tolerance.
  • Active optimization: the IV Plus (500 mg) is PHI’s most-prescribed protocol, often paired with 100 mg IM shots between infusions.
  • Advanced longevity protocols: the IV Ultra (1,000 mg) is reserved for experienced patients with established tolerance, typically as part of a comprehensive longevity program.

Frequency is individualized. Some patients pursue weekly or biweekly infusions during initiation, then transition to monthly maintenance with IM shots between sessions.

Why Patients Choose PHI for NAD+ Therapy

01

Physician-prescribed, not menu-selected

Each NAD+ protocol is recommended by a physician after evaluating your situation. PHI is one of the few practices in Los Angeles offering physician-supervised NAD+ across five tiered protocols, meaningfully different from menu-style IV bars.

02

Tiered protocols with tolerance assessment

PHI’s five-tier system (50 mg through 1,000 mg) allows safe progression at the right pace. Some providers start patients at high doses regardless of experience, which can produce avoidable side effects.

03

Physician-supervised infusions

All NAD+ protocols are administered under physician supervision. Infusion duration varies by individual tolerance, and your physician monitors and adjusts the infusion rate as needed.

04

Integration with broader care

NAD+ therapy at PHI is integrated with peptide therapy, IV protocols, and other longevity interventions, designed as a comprehensive plan rather than treated in isolation.

05

Concierge, coordinated care

Single-physician continuity from consultation through treatment and return to activity. Patients receive clear guidance and transparent pricing at consultation.

What to Expect

Before

Evaluation

Your physician reviews your medical history, current medications, and any conditions that affect protocol selection. NAD+ therapy is not appropriate for patients with certain conditions (active cancers under treatment, severe kidney or liver disease, specific cardiovascular conditions); your physician will screen for these.

During

The infusion or shot

IV infusions take up to 2 hours (Lite), 4 hours (Plus), or 6 hours (Ultra) depending on the protocol, with the rate adjusted based on tolerance; slowing the rate often reduces side effects. IM shots take only minutes. You sit comfortably and most patients read, work, or rest.

After

Afterward

Most patients return to normal activities immediately. Some report increased mental clarity or energy within hours; others notice cumulative effects over a series of sessions.

Side effects

What can occur

Chest pressure, flushing, nausea, or muscle tension can occur, particularly during initial infusions or at higher doses. These typically resolve when the infusion rate is slowed, are dose-dependent, and tend to diminish with subsequent sessions as tolerance develops.
