The Myers cocktail is the original intravenous vitamin and mineral infusion, developed in the 1960s and still one of the most well-known IV protocols offered in wellness clinics today. If you have heard the name and want a plain-English explanation of what is inside the bag, where the formula came from, how it is given and what to expect at an appointment, this guide walks you through the essentials in line with current clinical references.
TLDR
- The Myers cocktail is an IV blend of B vitamins, vitamin C, magnesium and calcium, originally developed by Dr John Myers in the 1960s.
- It was refined and documented by Dr Alan Gaby in his 2002 Alternative Medicine Review article.
- A typical infusion runs over about 30 to 60 minutes through a small cannula in the arm.
- It is commonly used to support hydration, energy, immune function and recovery for the right person.
- High-quality randomised trial evidence is still limited beyond hydration and correcting documented deficiencies (MSD Manuals, 2025).
- It is not a cure and is not a substitute for primary medical care.
- IV Health Sunshine Coast delivers Myers cocktail-style infusions at the Sippy Downs clinic, via Sunshine Coast mobile visits and through rural expressions of interest.
Where the Myers cocktail comes from
The Myers cocktail is named after Dr John Myers, a physician in Maryland who used intravenous nutrient infusions from the 1960s to support patients with a range of chronic conditions. After Dr Myers passed away, integrative physician Dr Alan Gaby treated many of his former patients and refined the original formula, publishing a comprehensive review in the journal Alternative Medicine Review in 2002 (Gaby, 2002). Today most clinics use a Gaby-influenced version of the original recipe, summarised in the MSD Manuals Professional Edition as a high-dose B vitamin, vitamin C, magnesium and calcium infusion in sterile water (MSD Manuals, 2025).
What is in a Myers cocktail
The classical Myers cocktail combines a small group of vitamins and minerals that play essential roles in normal energy, nervous and immune function. The MSD Manuals reference describes the formula as high doses of B vitamins, vitamin C, magnesium, calcium, hydroxocobalamin (vitamin B12), pyridoxine (vitamin B6) and dexpanthenol (B5), mixed with sterile water (MSD Manuals, 2025). The table below summarises what each ingredient does in general terms.
Ingredient | General role in the body |
Magnesium | Muscle and nerve function, energy metabolism |
Calcium | Bone and heart function, muscle contraction |
Vitamin C | Antioxidant, supports immune function |
B-complex vitamins | Energy metabolism and nervous system support |
Vitamin B12 (hydroxocobalamin) | Nerve health, red blood cell formation |
Vitamin B6 (pyridoxine) | Protein metabolism, brain function |
Dexpanthenol (B5) | Cellular energy and tissue support |
This is the general formula. At IV Health Sunshine Coast, doses and additions are personalised after a consultation and, where required, a telehealth review with an integrative medical practitioner.
How a Myers cocktail is given
The infusion is delivered through a small cannula placed in a vein, usually in the arm. The nutrient mix is run slowly over about 30 to 60 minutes in a calm clinical setting, with a registered nurse present. Because the nutrients bypass the digestive tract, they enter the bloodstream directly, which avoids the variable absorption that can happen with oral supplements. The team can talk through the IV infusion options available and recommend a protocol that suits your goals and health profile.
What it is commonly used for
Across the clinical literature, the Myers cocktail is most often used as a general nutrient and hydration support, and as an adjunct for specific conditions. The reasons people choose it tend to fall into a few common themes, summarised below. The language is qualified throughout, because individual outcomes vary.
Energy support and fatigue
B-complex vitamins, magnesium and vitamin C are involved in normal energy metabolism. People who are run down, post-illness or recovering from a stressful period sometimes choose a Myers cocktail to support their energy. While many users report a subjective lift, MSD Manuals notes that high-quality trial evidence for energy benefits is still limited (MSD Manuals, 2025). If you would prefer a shorter visit, quick vitamin boosters are a smaller intramuscular alternative that takes around 10 minutes.
Immune support during stress
Vitamin C, B vitamins and minerals like magnesium and zinc support normal immune function. A Myers cocktail-style infusion is sometimes used during high-stress periods or seasonal change. It is not a substitute for vaccination, balanced nutrition or sleep, and it should not be used to try to prevent or treat a specific infection.
Hydration after illness or exertion
IV fluids are well-established for rehydration when oral intake is not enough. People often choose a Myers cocktail after an event, intense training, illness or travel-related dehydration. Hydration support is the most well-accepted use case for IV therapy generally.
Adjunct support for specific conditions
In his 2002 review, Dr Gaby described using the Myers cocktail as an adjunct in conditions including fibromyalgia, migraine, chronic fatigue, acute asthma and acute infections (Gaby, 2002). A 2009 placebo-controlled pilot study in fibromyalgia reported patient improvements in pain, depression and quality of life over eight weeks, but did not find a significant difference between the Myers cocktail group and placebo (Ali et al, 2009). This is a useful reminder that subjective improvement is common and trial evidence is still developing.
What the evidence currently shows
The Myers cocktail has more than half a century of clinical use behind it, but high-quality randomised trials supporting many of the commonly promoted benefits are still limited (MSD Manuals, 2025). Evidence is strongest for hydration support and for correcting documented vitamin or mineral deficiencies.
In 2018, the US Federal Trade Commission took action against a company making unsupported disease claims about Myers cocktail-style infusions, which is part of why qualified language matters when discussing benefits (MSD Manuals, 2025). For Australian readers, the practical message is that the Myers cocktail can be a useful nutrient and hydration support for the right person, not a treatment for disease.
Who Myers cocktail therapy suits
A Myers cocktail-style infusion may suit:
- Wellness-minded adults aged roughly 30 to 65 on the Sunshine Coast
- Busy professionals and parents wanting practical preventative support
- Athletes and active people recovering from training or events
- Frequent travellers managing dehydration and jet lag
- People recovering from illness, fatigue or surgery, with their treating practitioner’s input
Suitability is confirmed during a free 15 minute telehealth nursing consultation. If a prescription is required, a brief telehealth review with the integrative medical practitioner is added before any infusion is booked.
Risks and important safety notes
The Myers cocktail is generally low risk when delivered by a registered clinician after screening, but it is not risk free. Common considerations include:
Possible risk | Why it matters |
Bruising or infection at the cannula site | Minor, reduced by trained insertion technique and single-use consumables |
Drop in blood pressure if infused too quickly | Linked mainly to magnesium, managed by infusion speed (MSD Manuals, 2025) |
Arrhythmia or muscle weakness with electrolyte abnormalities | Why screening matters before any infusion (MSD Manuals, 2025) |
Vitamin toxicity at very high doses | Why personalised dosing under clinical oversight is important |
Medication interactions | Magnesium with antihypertensives, calcium with ceftriaxone, B6 with certain blood medicines (MSD Manuals, 2025) |
Pregnancy and breastfeeding | Safety has not been studied; discuss with your treating doctor (MSD Manuals, 2025) |
Pre infusion testing including HTMA and other functional screening is built into the IV Health Sunshine Coast model to help tailor protocols safely.
What to expect at your appointment
Most people start with a free 15 minute telehealth nursing consultation. If a prescription is needed, a brief telehealth review with the integrative medical practitioner is added. From there you can book at the Sippy Downs clinic, request a mobile visit across the Sunshine Coast, or submit an expression of interest for rural visits to Bundaberg, Eidsvold, Monto and Crows Nest. At the appointment, you settle into a calm monitored space, a registered nurse inserts the cannula, and the infusion runs over roughly 30 to 60 minutes. Single-use consumables are used for every session.
