Quick Answer
A Myers’ cocktail is an IV infusion of magnesium, calcium, B vitamins and vitamin C, named after Dr. John Myers, a physician who used it with his patients for years. It is popular for fatigue, migraines and general wellness, but controlled research is limited. In the best-known trial, in people with fibromyalgia, both the Myers’ group and the placebo group improved, with no significant difference between them. Many people get enough of these nutrients from food or oral supplements, so it helps to talk with a provider about whether an infusion makes sense for you.
Who this is for: adults curious about the Myers’ cocktail who want to know what’s in it and what research shows
What's in a Myers' Cocktail
A Myers’ cocktail is a mix of vitamins and minerals given through an IV. The classic formula includes:[1]
- Magnesium
- Calcium
- B vitamins, often including B12, B6 and others
- Vitamin C
Exact ingredients and doses vary by clinic and pharmacy. Many IV drips offered today build on this basic formula and add other nutrients.[2]
Where the Myers' Cocktail Came From
The formula is named for Dr. John Myers, a Baltimore physician who gave his patients injections of vitamins and minerals for many years. After his death, Dr. Alan Gaby continued and adjusted the approach and described it in a 2002 review.[1]
That review reported on his clinical experience with conditions such as migraines, fatigue, fibromyalgia and asthma. Clinical experience can point researchers in useful directions, but it is not the same as a controlled study.
Leafy greens, beans, citrus and whole grains supply the same nutrients found in a Myers’ cocktail.
What the Research Shows
The best-known controlled trial tested the Myers’ cocktail in 34 adults with fibromyalgia. Participants received weekly infusions of either the nutrient mix or a placebo IV fluid for eight weeks.[3]
Both groups improved, and there was no statistically significant difference between them. The researchers pointed to a strong placebo response and a small study size, and they concluded that the benefit compared with placebo remains uncertain.[3] Cleveland Clinic experts describe the overall evidence for IV vitamin therapy as limited and still in need of high-quality studies.[2]
IV Nutrients and Your Diet
An IV drip is not a replacement for a balanced diet, good sleep, exercise or prescribed medication.[2] IV delivery skips digestion and raises blood levels quickly, but that does not mean it works better than oral supplements for most people. For a closer look, see IV vitamins vs. oral supplements.
Some people do have true shortages, such as low B12 or magnesium, often because of a medical condition or medication. Lab testing can help show who may benefit from added nutrients and in what form.
Safety and Who Should Be Cautious
Possible risks include bruising or infection at the IV site, side effects from high doses and interactions with medications.[2] Some people feel warmth or flushing while magnesium is infused. Cleveland Clinic advises talking with your regular provider first and says IV vitamin therapy is best avoided by people with:[2]
- Heart disease
- High blood pressure
- Kidney disease
- A current pregnancy
How We Approach the Myers' Cocktail at Lake Forest Regenesis
Allana reviews your symptoms, health history, medications and, when helpful, your labs before recommending a Myers’ cocktail. She looks first for medical causes of fatigue, headaches or body aches (see common medical causes of fatigue). If you choose an infusion, it is given in the clinic’s IV lounge with a provider on site, and drips usually take 30 to 60 minutes. She is honest about what the research shows so you can decide with realistic expectations.
When to See a Provider
During an infusion, tell staff right away about chest pain, trouble breathing, a racing or irregular heartbeat, or swelling of the face or lips. If these happen outside the clinic, call 911. Seek prompt care for fever, chills or spreading redness at an IV site. Book a visit if fatigue, headaches or body pain keep coming back, since these deserve a full evaluation.

Frequently Asked Questions
Will a Myers' cocktail give me more energy?
Some people say they feel better afterward, but studies have not confirmed a reliable energy benefit. If low energy is ongoing, it is worth looking for a medical cause.
How often do people get a Myers' cocktail?
There is no proven schedule. The fibromyalgia trial used weekly infusions for eight weeks, and your provider can discuss what is reasonable for you.
Is a Myers' cocktail the same as a hydration IV?
Not exactly. Hydration drips focus on fluids and electrolytes, while a Myers' cocktail adds vitamins and minerals to the fluid.
Can I get the same nutrients by mouth?
Yes. Magnesium, calcium, B vitamins and vitamin C are all found in foods and oral supplements, and for most people these are a reasonable place to start.
