What It Does
Seven Reasons Clinicians Recommend NAD+ & B12
A powerful dual-compound injection — NAD+ restores cellular energy and DNA repair, while Vitamin B12 supports neurological function and nerve health. Delivered subcutaneously for maximum bioavailability.
Boosts Cellular Energy
NAD+ enhances ATP production — the energy currency that powers every cell. Restoring NAD+ levels via injection translates directly into improved stamina, vitality, and resistance to physical and mental fatigue. B12 further supports this through its role in red blood cell formation and oxygen transport.
Supports Cognitive Function
NAD+ fuels the metabolic demands of neurons while B12 supports neurotransmitter synthesis and myelin sheath integrity — the protective coating around nerve fibers essential for fast, clear signal transmission. Together they improve focus, memory, and mental clarity.
Enhances DNA Repair & Longevity
NAD+ activates sirtuins and PARP enzymes — the primary regulators of DNA repair and cellular aging. B12 supports DNA methylation pathways essential for gene expression regulation. Together they represent one of the most clinically studied combinations for healthy aging at the cellular level.
Reduces Fatigue
Combats chronic fatigue and enhances recovery from both physical exertion and mental stress. NAD+ restores mitochondrial efficiency while B12 addresses fatigue rooted in neurological depletion or B12 deficiency — making this combination effective across a broader range of fatigue causes than NAD+ alone.
Supports Nervous System Health
Vitamin B12 is essential for neurological function — supporting nerve repair, myelin production, and neurotransmitter balance. B12 deficiency is more common than most people realize and presents as fatigue, cognitive fog, and mood disruption. This injection addresses that directly.
Metabolic Support
Optimizes glucose metabolism, mitochondrial function, and overall energy efficiency. NAD+ supports the core metabolic enzymes involved in energy conversion, while B12 plays a critical role in fatty acid and amino acid metabolism — together improving how efficiently your body processes and uses nutrients.
Neuroprotective Effects
Both NAD+ and B12 demonstrate neuroprotective properties — reducing oxidative stress, supporting long-term brain health, and helping defend neurons against age-related decline and environmental stressors. Their combined action provides broader neuroprotection than either compound individually.

Why Lavi MD
Not All Peptide Brands Are Equal
Most peptide suppliers prioritize volume over patients. We were built differently — by a physician, for patients.

"Every product we offer is something I would prescribe to my own patients. Our formulations are designed for clinical outcomes — not marketing claims."
How We Operate
Built by a Physician, Not a Marketing Team
Lavi MD was founded under physician supervision. Every formulation, every dose, every protocol is reviewed by Dr. Moulavi before it reaches a patient — not outsourced to a contract manufacturer with no clinical input.
We Limit Shipping Days to Protect Your Product
We only ship Monday and Tuesday. That's a deliberate decision — it ensures your order arrives before the weekend and never sits in a carrier facility over two days without refrigeration. Most brands don't think that far ahead.
We Treat You Like a Patient, Not an Order Number
Our team includes clinical staff who understand what you're taking and why. If something goes wrong with your order — a warm shipment, a missing component, a question about your protocol — we fix it. No automated runaround.
