IV therapy, or intravenous therapy, involves delivering fluids, medications, or nutrients directly into a vein. It has been used for decades in hospitals to treat a range of conditions, from dehydration to nutrient-absorption disorders. Recently, IV hydration and vitamin therapies have gained popularity outside of hospitals as a potential hangover remedy and wellness treatment. While these therapies tout benefits such as increased hydration and elevated vitamin levels, their effectiveness remains debated. This article explores the benefits and risks of IV therapy, particularly in the context of weight loss.
What is IV Therapy?
IV therapy involves inserting a small tube, or catheter, into a vein, which is attached to a bag of fluids. These fluids, a mixture of water and other solvents or vitamins, are released through the tube directly into the bloodstream. This method allows treatments to bypass the digestive system, enabling them to start working rapidly.
IV therapies are not limited to hydration; they also include vitamin and nutrition therapies. IV vitamin therapy administers a high concentration of minerals and vitamins directly into the bloodstream rather than through the stomach. A mix known as the Myers’ cocktail includes high doses of B vitamins, vitamin C, calcium, and magnesium. Medications can also be administered through IVs, such as ketamine therapy for mental health, chemotherapy for cancer, or iron infusions for iron-deficiency anemia.
IV Therapy Benefits
The primary advantage of IV therapy is the ability to deliver nutrients and medications directly into the bloodstream, bypassing the digestive system entirely. This allows for faster absorption and more efficient delivery of substances to the body.
Rapid Delivery
IV therapy sends treatments directly into the bloodstream, enabling them to start working rapidly - more quickly than oral treatments, such as pills you swallow or solutions you drink.

Enhanced Support
IV-based treatments can offer heightened support to patients who cannot take in fluids orally or whose digestive absorption capabilities are impaired. People who have undergone types of bariatric surgery have reduced digestive absorption capabilities and may benefit from IV interventions to receive certain treatments. People who experience excessive vomiting may also benefit from IV-based treatments if they cannot hold down food or water.
Hydration and Recovery
Many have found IV therapy helpful in recovery from heavy alcohol consumption or hangovers because of the immediate hydration benefit.
Improved Bioavailability
Oral supplements must traverse the GI tract, where their absorption can be significantly affected by factors such as gastric acidity, digestive enzyme activity, the health of the gut microbiota, and underlying medical conditions. Nutrients administered intravenously have virtually 100% bioavailability, directly entering systemic circulation without being subjected to digestive processes.
Circumventing Hepatic First-Pass Metabolism
IV nutrient therapy circumvents hepatic first-pass metabolism, a significant limitation of oral supplements. Nutrients given orally must first pass through the liver, where substantial metabolism occurs, reducing their potency and bioavailability.
Achieving Therapeutic Nutrient Concentrations
IV vitamin therapy can achieve therapeutic nutrient concentrations that are unattainable through oral administration. High-dose vitamin C therapy delivered intravenously can achieve plasma levels up to 100 times higher than those achieved orally, offering valuable therapeutic benefits in immune enhancement, accelerated wound healing, and as an adjunctive treatment in cancer management.

Treating Nutrient Deficiencies
IV vitamin therapy proves highly effective in treating nutrient deficiencies, particularly in populations at increased risk due to malabsorption disorders, post-bariatric surgery, or chronic health conditions. IV therapy provides a reliable solution for rapidly correcting such deficiencies, notably for water-soluble vitamins like B12, folate, and vitamin C.
Customizable Treatment
A significant strength of IV vitamin therapy lies in its customizability, allowing healthcare providers to formulate individualized nutrient combinations tailored to specific patient needs.
Weight Loss Support
IV therapy for weight loss involves administering vitamins, minerals, or medications directly into your vein. IV fluids can support your metabolic function, detoxify your body, and rehydrate you. They also provide vitamins and minerals to balance your nutritional intake and aid muscle recovery after workouts.
Hydration: IV fluids can help replenish fluid levels and reduce water retention, which can contribute to weight gain.
Nutrient Delivery: Nutrients are delivered directly into your bloodstream through IV therapy, ensuring maximum absorption.
Appetite Suppressants: Some IV therapies, like the "skinny drip," involve a blend of vitamins B and C, known to metabolize fats and carbohydrates, and convert glucose into energy. Some also offer IV medications or hormone therapies with potential appetite-suppressing effects.
Boosting Metabolism: By delivering essential nutrients like B vitamins and amino acids directly into your bloodstream, IV therapy can give your metabolism the boost it needs to work more efficiently, helping convert food into energy faster and making it easier for your body to burn fat.
Enhancing Energy Levels: With the right combination of nutrients, like B vitamins and electrolytes, IV therapy helps restore your energy quickly, making it easier to power through your workouts and stay active during the day.
Detoxification: By delivering powerful antioxidants like vitamin C and glutathione, IV therapy helps flush out toxins that could be slowing down your metabolism, improving digestion and fat-burning processes.
IV Therapy Risks and Side Effects
IV therapies can be safe and effective treatments, but they are not without risks.
Infections
Infections can result from IV therapy. Proper administration requires rigorous adherence to sterility protocols to minimize complications, such as infections or abscess formation. In wellness-focused settings like spas or mobile home services, adherence to sterile techniques might fall short of medical standards, potentially increasing risks.

Allergic Reactions
Allergic reactions to components within IV formulations, ranging from mild symptoms to severe anaphylaxis, are possible.
Blood Clots and Nerve Damage
Blood clots and nerve damage can result from IV therapy.
Vitamin Imbalance
Unbalanced levels of some vitamins may lead to side effects, including permanent nerve damage. It’s important to discuss any supplements or medications you take with a healthcare professional before getting a vitamin IV.
Lack of Regulation
IV hydration clinics are not federally regulated, and state-based regulations vary widely. IV therapies are often administered through unregulated clinics, which are subjects of controversy. There are concerns about the low level of oversight for wellness centers and hydration clinics, including "reports of unqualified individuals without the proper credentials or training administering the infusions.”
Potential for Overload
Excessive administration of nutrients, particularly fat-soluble vitamins like A, D, E, and K, can accumulate in tissues and lead to toxic effects. Similarly, improper fluid infusion can cause electrolyte imbalances or fluid overload, negatively impacting cardiovascular and renal functions.
Cost
IV vitamin therapy is typically expensive, with individual sessions often costing between $100 to over $300, depending on the formulation and provider. Since such therapies are rarely covered by health insurance, their cost-effectiveness compared to oral supplementation or improvements in diet and lifestyle habits is questionable.
Limited Evidence
One key disadvantage of IV vitamin therapy in wellness contexts is the lack of solid evidence supporting its benefits for healthy individuals. Despite claims that IV therapy can enhance energy, boost immunity, or improve skin health, these purported benefits are primarily anecdotal or based on self-reported outcomes rather than well-designed randomized clinical trials.
What to Expect During IV Therapy
If it’s your first time receiving IV hydration therapy, it's normal to feel a little nervous before the appointment.
Procedure
During an IV therapy session, a healthcare professional will insert a small, sterile needle into a vein, typically in your arm, and connect it to a tubing system. The chosen IV therapy solution will then be administered at a controlled rate, allowing the nutrients to be delivered directly into your bloodstream.
Sensations
You can expect to feel a quick prick or slight pinch when the needle is first inserted into your vein. Then, there can be a slight sensation of coolness as the fluids start to flow. After the initial prick, you should feel relatively comfortable during the treatment. You may be sitting in a comfortable reclining chair or a bed and may even be able to participate in a light activity like listening to music, reading, spending some time on your phone, or taking a nap.
What to Avoid After IV Therapy
After receiving IV therapy, certain precautions are recommended for the best possible outcomes.
Activities to Avoid
Refrain from vigorous physical activities such as heavy lifting or strenuous exercises to allow your body time to recover. Avoid immersing the IV site in water immediately after therapy to prevent potential infections. Do not attempt to remove or adjust the IV yourself.
Foods and Beverages to Avoid
Stay away from alcohol and caffeine for at least 24 hours following the treatment, as these substances can act as diuretics, potentially interfering with the absorption and effectiveness of the IV therapy. Avoid spicy or acidic foods, as these can irritate the IV site, causing discomfort or inflammation. Maintain a healthy diet, avoiding processed food and food high in sugar.
Other Precautions
Avoid drinking excessive amounts of fluid, as it could dilute the therapy’s effects and potentially lead to overhydration. Monitor the IV site for any signs of redness, swelling, or discharge. Notify your healthcare provider promptly if you experience any discomfort or changes. Keeping the IV arm elevated can help reduce swelling and promote fluid drainage.
Consultation Before IV Therapy
Before starting IV therapy, it is highly recommended that you schedule a consultation with an experienced healthcare provider. During this consultation, your health history, current health status, and personal health goals will be evaluated. This comprehensive evaluation helps understand your body’s specific requirements and allows the treatment to be tailored accordingly. It's critical to disclose any medical conditions, allergies, or medications you are currently taking to your healthcare provider.
Is IV Therapy Safe for Weight Loss?
When administered by a trained healthcare professional, IV therapy for weight loss is generally safe. Even so, it is important to follow all guidelines and disclose any medical conditions or allergies to ensure your safety during the procedure. Consulting with a healthcare professional experienced in IV therapy is highly recommended before starting any treatment. Also, it is important to remember IV infusion is not a benign risk-free therapy. The infusion medication is going directly into your blood vessels - and the next stop is your heart.
How Often Should You Get IV Therapy for Weight Loss?
The frequency of IV therapy sessions for weight loss can vary based on individual needs and goals. Some individuals may benefit from weekly sessions, while others may opt for bi-weekly or monthly treatments.
Alternative Weight Loss Strategies
Implementing other proven weight loss strategies alongside your IV therapy is crucial, as relying solely on this method may not deliver your expected long-term results.
Creating a Balanced Diet
Create a balanced diet incorporating fruits, veggies, protein, whole grains, and healthy fats.
Incorporating Daily Movement
Aim for at least 30 minutes of movement daily, finding activities that are meaningful and enjoyable for you.
Using Medications
Some prescription medications can lead to significant weight loss.
Seeking Surgical Options
Some procedures can have long-lasting weight loss results.
