IV Vitamin Therapy — Myers' Cocktail, NAD+, Glutathione

Longevity Medical Clinic's Kirkland location offers IV vitamin therapy sessions open to both existing members and non-patients. Available formulas include the Myers' Cocktail (B vitamins, vitamin C, calcium, magnesium) for immune support and energy, NAD+ (nicotinamide adenine dinucleotide) for cellular repair and cognitive function, and glutathione for antioxidant restoration and inflammation reduction. Sessions run 30–60 minutes depending on the formula selected. Members receive a 20% discount.

Longevity Medical Clinic's IV vitamin therapy suite at the Kirkland location brings intravenous micronutrient delivery to the Seattle Eastside — one of the only preventive medicine clinics in the area where IV therapy is offered alongside a full hormone optimisation programme under the same physician-led team. The Myers' Cocktail is the most widely administered formula at the clinic and the historical foundation of IV micronutrient therapy, originally developed by Baltimore physician John Myers in the 1970s. The infusion delivers a concentrated blend of B vitamins (B1 thiamine, B2 riboflavin, B3 niacinamide, B5 pantothenic acid, B6 pyridoxine, B12 hydroxocobalamin), high-dose vitamin C, calcium gluconate, and magnesium chloride directly into the bloodstream, bypassing the absorption limitations of oral supplementation. Patients commonly report improvements in energy, immune resilience, mental clarity, and mood — effects attributed to the rapid repletion of nutrients that are frequently depleted in high-stress, high-activity lifestyles common in the Seattle tech sector. NAD+ therapy delivers nicotinamide adenine dinucleotide — a coenzyme central to mitochondrial energy production, DNA repair, and sirtuin activation pathways associated with cellular longevity. NAD+ declines with age and chronic stress; IV replenishment bypasses the limited oral bioavailability of NAD+ precursors like NMN or NR and achieves systemic levels more rapidly. Sessions are longer than a standard Myers' and are paced slowly to minimise the mild chest tightness and warmth that some patients experience at higher infusion rates. Glutathione is the body's primary endogenous antioxidant, produced in the liver and rapidly consumed by oxidative stress, environmental toxins, and chronic inflammation. IV glutathione replenishes this reserve more effectively than oral forms, which are largely degraded in the gastrointestinal tract before reaching systemic circulation. The infusion supports liver detoxification pathways, reduces oxidative burden, and is frequently used as a complement to NAD+ sessions. All IV sessions at the Kirkland clinic are administered by trained medical staff under physician oversight. Existing members of the Premier or Platinum Health Membership receive a 20% discount. Non-patients are welcome to book individual sessions without joining a membership programme. The clinic is located at 11335 NE 122nd Way, Suite 250, in Kirkland, conveniently accessible from Bellevue, Redmond, Bothell, and the broader Seattle Eastside.
