The Myers Cocktail is a blended intravenous infusion of key vitamins and minerals formulated in the 1960s–70s by Baltimore physician John Myers, MD, and later refined and published by integrative medicine physician Alan Gaby, MD. Because nutrients are delivered directly into a vein, they bypass the digestive tract entirely — meaning the body receives a much higher concentration than any oral pill or powder can typically deliver. It is one of the most widely administered integrative IV therapies in North America.

When vitamins and minerals are given intravenously, blood levels temporarily reach concentrations far above what the gut can absorb orally. This higher concentration can saturate tissues that are depleted, re-energize cells that depend on nutrients like magnesium and B12 to produce energy, and support immune pathways that need vitamin C to function well. For people with absorption problems or chronically low nutrient status, this bypass of the digestive system is often the key advantage.

The standard delivery is a slow IV infusion over 20–60 minutes, though some practitioners use a slower IV push over 5–15 minutes. The exact formula and concentrations vary by clinic and practitioner — there is no single fixed 'official' recipe, which is why formulations can differ significantly between providers. Some clinics offer add-ons such as glutathione, zinc, or higher-dose vitamin C.

• Chronic fatigue and low energy
• Fibromyalgia
• Migraine and tension headaches
• Asthma (acute and chronic)
• Nutrient deficiencies and malabsorption
• Depression and low mood
• Immune support and frequent illness
• Upper respiratory infections
• Athletic recovery and performance
• Chronic pain conditions

• Migraine recurrence (when given as regular maintenance infusions in magnesium-deficient patients)
• Nutrient deficiency relapse in patients with documented malabsorption

The Myers Cocktail is an IV medical treatment — not a food or supplement you can eat. However, you can support the same nutritional goals through diet. For magnesium: dark leafy greens (spinach, chard), pumpkin seeds, black beans, and dark chocolate are excellent sources. For B vitamins: eggs, salmon, beef liver, nutritional yeast, and legumes cover most of the B complex. For vitamin C: bell peppers, kiwi, citrus fruits, and broccoli are among the richest sources. For calcium: dairy, sardines with bones, and fortified plant milks help round out the formula. An anti-inflammatory, whole-food Mediterranean-style diet is the best long-term dietary foundation for maintaining the nutrient levels the Myers Cocktail aims to restore. Foods to limit: Alcohol — depletes B vitamins (especially B1 and B12) and magnesium rapidly, Heavily processed foods high in refined sugar — increase magnesium excretion and B-vitamin demand, Excessive coffee — can increase urinary magnesium loss when consumed in large quantities.

• Warm flushing sensation during infusion (especially with magnesium — normal and harmless)
• Temporary drop in blood pressure during or shortly after infusion
• Dizziness or lightheadedness (usually resolves within minutes of slowing the infusion)
• Fatigue or tiredness the day after infusion (often a sign of detox or rebalancing)
• Vein irritation or mild bruising at the IV site
• Metallic or unusual taste in the mouth during infusion
• Nausea (uncommon, usually from too-rapid infusion of B vitamins or high-dose vitamin C)
• Very rarely: cardiac arrhythmia (with excessive magnesium or in patients with kidney impairment)
• Infection or phlebitis at injection site (rare with proper sterile technique)

• Recommended daily: A standard Myers Cocktail infusion contains approximately: Magnesium chloride 1–5 g, Calcium gluconate 1–2 g, Vitamin B12 1,000 mcg, Vitamin B6 100 mg, B-complex (B1, B2, B3, B5) 1 mL of a standard B-complex preparation, Vitamin C 1–6 g, Folic acid 1 mg — diluted in 100–250 mL of normal saline or sterile water. Exact formulations vary by clinic.
• Best time of day: Morning or early afternoon is generally preferred — the energy-boosting effect of B vitamins can interfere with sleep if given in the evening.
• With or without food: A light meal or snack before the infusion is recommended to reduce the chance of nausea and blood sugar fluctuations during the drip. Avoid arriving on an empty stomach.
• Time to effect: Energy and acute symptom relief: often within hours to 24 hours. Sustained improvement for chronic conditions: typically after 4–8 weekly infusions.
• How long to take it: For acute conditions (migraine, cold): 1–3 infusions as needed. For chronic conditions (fibromyalgia, chronic fatigue): an initial series of 4–8 weekly infusions is typical, followed by monthly maintenance infusions as needed. Long-term frequency should be guided by a licensed provider based on individual response and nutrient testing.
