What It Does
Six Reasons Clinicians Recommend the NAD+ · Glutathione Stack
Two of the most widely used compounds in functional medicine and longevity protocols — delivered together in a single subcutaneous injection. NAD+ drives cellular energy and DNA repair while Glutathione, the body's master antioxidant, neutralizes the oxidative damage that energy production generates.
NAD+ — The Energy & Repair Molecule
Powers the electron transport chain for ATP synthesis, activates sirtuins for DNA repair and longevity signaling, and supports every energy-demanding process in the cell. Declines by up to 50% by midlife.
Glutathione — The Master Antioxidant
The body's primary defense against oxidative stress — neutralizing free radicals, supporting liver detoxification, regenerating vitamins C and E, and protecting cells from the oxidative byproducts of high metabolic activity.
Restores Cellular Energy & Combats Fatigue
NAD+ directly restores the mitochondrial energy production that declines with age, stress, and chronic illness — driving ATP synthesis and improving the efficiency of the electron transport chain. Glutathione protects the mitochondria from oxidative damage that impairs energy output. Together they address both the fuel deficit and the oxidative damage that causes persistent fatigue at its cellular source.
Comprehensive Oxidative Stress Protection
NAD+ supports Glutathione regeneration via NADPH — the reducing agent required to convert oxidized Glutathione (GSSG) back to its active form (GSH). This biochemical relationship means the two compounds are mutually reinforcing — NAD+ keeps Glutathione active, and Glutathione neutralizes the ROS that would otherwise deplete NAD+. The result is a self-sustaining antioxidant system more robust than either compound alone.
Supports Brain Health & Cognitive Clarity
NAD+ restores the energy metabolism of neurons — among the most metabolically demanding cells in the body. Glutathione reduces neuroinflammation and protects neural tissue from oxidative damage that accumulates with age. Together they support sustained mental clarity, reduce brain fog, and protect the neurological function that energy depletion and oxidative stress progressively erode.
Enhances DNA Repair & Healthy Aging
NAD+ activates sirtuins and PARP enzymes — the primary molecular drivers of DNA repair and cellular longevity signaling. Glutathione protects DNA from the oxidative damage that creates the repair demand in the first place. Together they work upstream and downstream of the same aging pathway — reducing the rate of DNA damage while simultaneously improving the speed and accuracy of repair.
Strengthens Immune Function
Glutathione is essential for optimal immune cell function — T-cell proliferation, natural killer cell activity, and macrophage function all depend on adequate intracellular Glutathione levels. NAD+ supports the metabolic demands of immune activation. Together they prime the immune system for a more robust and sustained response while reducing the chronic inflammation that suppresses long-term immune competence.
Detoxification & Liver Support
Glutathione is the liver's primary detoxification molecule — conjugating heavy metals, environmental toxins, and metabolic waste products for safe excretion. NAD+ supports the hepatic energy metabolism that powers the liver's detoxification processes. Together they enhance total detoxification capacity and protect liver cells from the oxidative stress of processing metabolic and environmental toxin loads.
Why These Two Work Better Together
NAD+ and Glutathione are biochemically linked — NAD+ metabolism generates NADPH, which is required to regenerate active Glutathione from its oxidized form. Without adequate NAD+, Glutathione recycling slows and antioxidant capacity drops. Without adequate Glutathione, oxidative stress depletes NAD+ faster than cells can synthesize it. Stacking them together maintains both systems at peak function simultaneously.

Formulated by Dr. Sasson Moulavi
Every Lavi MD peptide is developed under the direction of Dr. Sasson Moulavi, the physician behind the brand. Formulations are built to clinical specification, not sourced from anonymous suppliers.
Dr. Moulavi earned his Doctor of Medicine from the University of Toronto and completed postgraduate training at McGill University in Montreal. He holds Board Certification in Anti-Aging Medicine and Bariatric Medicine, and is a member of the American Academy of Anti-Aging Medicine and the American Society of Bariatric Physicians. With over three decades of clinical experience in bariatric, family, and anti-aging medicine, he serves as Medical Director and prescribing physician for Lavi MD, overseeing formulation standards and clinical protocols.

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.
Proud Members of the
American Peptide Association
