Drip therapy, commonly called IV drip therapy or IV vitamin therapy, is the practice of delivering fluids, vitamins, and minerals directly into your bloodstream through a vein. It’s used in hospitals for medical purposes like rehydration and nutrient replacement, but it has also become a popular wellness trend offered at standalone clinics, medical spas, and even mobile services that come to your home. Sessions typically last 30 to 60 minutes and cost between $100 and $300.
How It Works
The core idea behind drip therapy is simple: when nutrients enter your bloodstream directly, they skip your digestive system entirely. Normally, vitamins and minerals you swallow have to pass through your stomach and intestines, where acids break them down and specialized cells absorb what they can. That process is imperfect. Your gut has a limited capacity to absorb certain nutrients, and factors like food interactions, gut health, and natural transport limits all reduce how much actually reaches your blood.
Intravenous delivery has virtually 100% bioavailability, meaning everything in the bag reaches your circulation. The difference can be dramatic for certain nutrients. Vitamin C is a good example: when you take more than about one gram orally, your intestines hit a ceiling and simply can’t absorb the excess. Delivered intravenously, vitamin C can reach plasma levels up to 100 times higher than what’s possible through oral supplements. This is why IV nutrient therapy has legitimate medical applications for people whose bodies can’t absorb nutrients normally, such as patients with certain gastrointestinal conditions or chronic alcohol use disorder.
What’s in the Bag
Every IV drip starts with a base fluid. The most common is normal saline (salt dissolved in sterile water), though some use dextrose (sugar) in water or lactated Ringer’s solution, which contains sodium, chloride, potassium, calcium, and lactate for more aggressive fluid replacement. On its own, this base fluid treats dehydration.
Wellness-oriented drip therapy adds vitamins and minerals to these base fluids. The most well-known formula is the Myers’ Cocktail, developed decades ago by a Baltimore physician. It consists of high doses of B vitamins, vitamin C, magnesium, and calcium mixed with sterile water. A standard Myers’ Cocktail session runs about $190. Many clinics now offer modified versions of this formula or entirely different blends marketed for specific goals: immune support, energy, skin health, athletic recovery, or hangover relief.
Other common add-ons include the antioxidant glutathione, amino acids, and various B vitamin combinations. Specialized treatments with more complex formulations can cost $300 or more, while basic hydration-only sessions start around $85 to $150.
What a Session Looks Like
There’s no major preparation needed. You may be asked to drink some water beforehand and avoid heavy meals, though a light snack is fine. When you arrive, a nurse or medical professional inserts a small needle into a vein in your arm, which connects to a bag of fluid hanging above you. The drip flows slowly by gravity or a pump. During the 30 to 60 minutes it takes, you sit in a chair and can read, scroll your phone, or simply relax. Once the bag is empty, the needle comes out, and you’re free to go.
Some people report feeling more energized or hydrated immediately afterward. Others notice very little. The experience itself is no different from receiving an IV at a hospital, just in a more spa-like setting.
What the Evidence Actually Shows
There’s an important distinction between medical IV therapy and wellness IV therapy. In medical settings, IV fluids and nutrients are used to treat diagnosed deficiencies, severe dehydration, and conditions where oral absorption is compromised. That use is well-supported by evidence.
The wellness side is a different story. Many drip therapy providers claim their infusions can boost immunity, reduce fatigue, relieve stress, and treat a variety of illnesses, even in people whose vitamin and mineral levels are already normal. According to Mayo Clinic physician Dr. Bauer, the evidence for these claims is limited. Very few studies have scientifically tested the wellness benefits of IV vitamins in healthy people, and many that do exist suffer from poor study design. There is limited evidence that IV vitamins provide benefit to people with normal nutritional intake and levels.
This doesn’t mean drip therapy can’t make you feel better in the short term. Receiving a liter of saline when you’re mildly dehydrated (after a long flight, a night of drinking, or an intense workout) will genuinely rehydrate you faster than drinking water. But whether the added vitamins do anything meaningful beyond what your kidneys simply filter out is still an open question. Your body excretes water-soluble vitamins it doesn’t need, so flooding your blood with high doses doesn’t necessarily mean your cells use more.
Safety Considerations
Any time a needle enters your vein, there are risks. Minor ones include bruising, soreness at the injection site, and a cool sensation as the fluid enters. More serious but rarer risks include infection, inflammation of the vein, and air embolism.
The bigger safety concern is how these treatments are prepared. The FDA has flagged concerns about IV hydration clinics, medical spas, and mobile infusion services that compound (mix) their own drug products. Because these drips are classified as compounded drugs, they must be prepared under sterile conditions following strict protocols. The FDA has noted that it’s often unclear whether these businesses are following state and federal regulations, whether a licensed practitioner is evaluating patients on-site, and whether proper sterile technique is being used. Contaminated or poor-quality compounded products can lead to serious illness, including death.
Certain medical conditions also make IV therapy risky. People with heart failure or kidney disease are particularly vulnerable because their bodies can’t handle rapid fluid shifts. Excess potassium or magnesium delivered intravenously can cause dangerous heart rhythm changes in people with kidney problems. High-dose vitamin C infusions can also be harmful for people with a history of kidney stones or certain enzyme deficiencies. A reputable provider will screen for these conditions before starting treatment.
Who Benefits Most
Drip therapy has its clearest value for people with specific medical needs. Patients recovering from bariatric surgery, for instance, often can’t absorb iron and other minerals normally because the procedure bypasses the parts of the gut where absorption happens. Oral iron supplements may take months to restore depleted stores, and high oral doses can actually trigger a hormone called hepcidin that blocks iron absorption further. Intravenous iron restores those stores much faster.
People with inflammatory bowel disease, chronic vomiting, severe food intolerances, or conditions that damage the intestinal lining may also benefit from IV nutrient delivery. Cancer patients receiving certain treatments sometimes receive high-dose IV vitamin C as a complementary therapy, though this remains an area of active investigation.
For otherwise healthy people eating a balanced diet, the value proposition is less clear. You’re paying $100 to $300 per session for something your body may simply excrete. If you’re curious, the lowest-risk option is a basic hydration drip at a clinic that employs licensed medical professionals, screens your health history, and prepares its infusions under proper sterile conditions.
