The Truth Behind Trendy IV Vitamin Therapy

“If you’re able to drink fluids — and your digestive system is working — that’s the best way to get them,” Shmerling says.

If you’re too sick or elderly to keep up with your body’s need for fluids by drinking, then you should be in a medical facility, he adds.

Not regulated by the FDA

The claims for IV therapy go beyond simple hydration, however. At most clinics, you can choose from a selection of concoctions, depending on your goal. There are different cocktails to cure a hangover, boost the immune system, improve energy, help with workout recovery, treat jet lag, improve skin, remove toxins and reverse the signs of aging.

There is little evidence to back any of those benefits, Shmerling says, and the clinics are not regulated by the Food and Drug Administration. “The marketing has gotten way out ahead of the science.”

In fact, most clinics include some variation of this disclaimer on their website and in marketing materials: “The services provided have not been evaluated by the Food and Drug Administration. … Any designations or references to therapies are for marketing purposes only.”

One of the few controlled clinical studies that looked at IV vitamin therapy compared to a placebo found that patients with fibromyalgia reported less tenderness and pain after receiving a specific infusion called a Myers’ Cocktail, a mix of magnesium, calcium, and vitamins C and B invented by a physician named John Myers.

But here’s the catch: Patients in the study who were injected with just saline solution reported the same positive results — a sign of “a strong placebo effect,” the study’s authors wrote.

Other risks abound

If you decide to try IV therapy, make sure you’re getting the treatment in a safe, clean environment. Also ask who will be administering your IV and how much experience they have, Torbati advises.

Because you are getting a needle placed in your arm, there is a chance of pain or bruising or, in rare cases, infection or inflammation of the vein. Older patients tend to have smaller veins, so placing an IV in someone over age 65 is more difficult than in a younger person. “The more frail and medically complex you are, the more cautious I would be about trying these things,” Torbati says.

It’s also important to ask exactly what substances will be going into your body.

Some drips have anti-inflammatory or anti-nausea medications that could cause an allergic reaction or interact with drugs a patient is currently taking, Torbati says. Other infusions include prescription drugs such as ketorolac and lidocaine that could lead to life-threatening adverse effects in some patients, according to a 2014 study published in the Journal of Parenteral and Enteral Nutrition.  

In 2018, supermodel Kendall Jenner was hospitalized after a bad reaction to a Myers’ Cocktail vitamin IV drip, according to news reports.

The takeaway

Although IV drips are low risk for most healthy people, medical experts generally recommend against them — mostly because they’re expensive and unnecessary. The cost of a vitamin drip ranges from a $79 first-time special at some clinics to hundreds of dollars for a special cocktail delivered to your home by a mobile provider.

“There’s nothing magical about getting vitamins in an IV,” Torbati says. “If you want extra nutrition, take a vitamin. If you have a headache, take a Motrin. Instead of spending hundreds on an IV, you can spend a nickel on a pill and get the same benefit.”
