What Is a Myers' Cocktail? Benefits, Ingredients, and What to Expect
Walk into any IV lounge in America and you'll find a Myers' Cocktail on the menu. It's the espresso of the IV world — the original, the classic, the one everything else is a variation of. But most people booking one couldn't tell you what's actually in the bag or where it came from.
So let's fix that. Here's everything you need to know about the Myers' Cocktail: what's in it, the history behind it, what it can (and can't) do, and what a session actually feels like.
A Quick History: Who Was Myers?
The Myers' Cocktail is named after Dr. John Myers, a physician at Johns Hopkins in Baltimore who spent the 1960s and 70s treating patients with intravenous vitamin and mineral infusions. He used his formula on people dealing with fatigue, migraines, fibromyalgia, and respiratory infections — conditions where he believed nutrient delivery straight into the bloodstream would outperform pills.
After Myers died in 1984, his patients didn't want to stop treatment. Another Baltimore physician, Dr. Alan Gaby, took over their care, refined the formula, and eventually published the paper that made the "Myers' Cocktail" famous in integrative medicine circles. Fifty-plus years later, it's the most requested vitamin infusion in the country.
What's Actually in a Myers' Cocktail?
The modern formula varies slightly between providers, but the core recipe includes four things diluted in sterile IV fluid:
| Ingredient | What It's For |
|---|---|
| Magnesium | Muscle relaxation, migraine relief, nervous system support |
| Calcium | Bone health, muscle and nerve function |
| B-Complex vitamins (B1, B2, B3, B5, B6) | Energy metabolism, brain function |
| Vitamin B12 | Energy, red blood cell production, nerve health |
| Vitamin C | Immune support, antioxidant protection, collagen production |
The magnesium is arguably the star of the show. It's the ingredient most responsible for the relaxed, warm feeling people report during the infusion, and it's the component with the strongest evidence for migraines and muscle tension. Most Americans don't get enough magnesium from diet alone, which is part of why the drip can feel noticeably different for some people.
What Are the Benefits?
Here's the honest version. The Myers' Cocktail has decades of clinical use and a lot of enthusiastic anecdotal support, but rigorous large-scale studies are limited. With that caveat on the table, the most commonly reported benefits are:
More energy. The B vitamins play a direct role in converting food into cellular energy, and B12 deficiency is a classic cause of fatigue. People who are run down, burning the candle at both ends, or recovering from illness tend to report the biggest difference.
Fewer and milder migraines. IV magnesium is one of the better-studied pieces of the formula, with real evidence for migraine sufferers. If headaches are your main concern, a dedicated migraine relief IV may be worth comparing too.
Immune support. The vitamin C and zinc (which many providers add) make the Myers' a popular choice at the first sign of a cold, or before travel and big events. For a heavier dose of immune firepower, some people opt for an immune boost IV instead.
General recovery. Because it combines hydration with broad-spectrum nutrients, the Myers' is a solid "reset button" after periods of stress, poor sleep, travel, or overtraining. It's a gentler, more general-purpose option than a targeted hangover IV or an athletic recovery drip.
Who probably won't notice much? Someone who's already well-hydrated, well-rested, and eating a nutrient-dense diet. If your baseline is high, there's less room for a vitamin infusion to move the needle — something we dug into in our post on whether IV therapy is worth it.
What Does a Session Feel Like?
A Myers' Cocktail infusion takes about 30 to 45 minutes. You'll sit in a comfortable chair, a nurse will place a small IV catheter in your arm (a quick pinch, then nothing), and the drip does its thing while you scroll your phone or zone out.
Two sensations are worth knowing about in advance. First, many people feel a spreading warmth or flushing as the magnesium goes in — totally normal, and providers can slow the drip if it's too intense. Second, some people notice a mild vitamin taste or smell mid-infusion. Also normal, also harmless.
Afterward, some people feel a difference within hours; for others it shows up the next day, mostly as steadier energy. Effects typically last several days to a week — we covered the timing question in detail in how long does IV therapy last.
How Much Does It Cost?
Nationally, a Myers' Cocktail runs about $149 to $275 depending on your city and whether you go to a lounge or book a mobile service that comes to you. That puts it in the mid-range of IV treatments — more than basic hydration, far less than NAD+ therapy. Our full IV therapy price guide breaks down what affects pricing.
One tip: providers in the same city can differ by $75 or more for essentially the same bag. It pays to compare before you book.
Is the Myers' Cocktail Right for You?
If you're new to IV therapy and want to try something with a long track record, the Myers' Cocktail is the natural starting point. It's the most balanced, most studied, and most widely available formula out there — a greatest-hits album rather than a niche deep cut.
Make sure you book with a licensed, reputable provider (here's what to look for), and let them know about any medications or health conditions beforehand — magnesium and high-dose vitamin C aren't right for everyone, particularly people with kidney issues.
