To get the lowdown on everything from what happens to your body during a session to the risks involved, here are three medical experts to weigh in: Dr. Dena Westphalen, a clinical pharmacist, Dr. Lindsay Slowiczek, a drug information pharmacist, and Dr. Debra Sullivan, a nurse educator who specializes in complementary and alternative medicine, pediatrics, dermatology, and cardiology.
DW: Vitamin infusions are being used for a wide variety of health concerns. Conditions that have responded positively to the Myers’ cocktail treatment include asthma, migraines, chronic fatigue syndrome, fibromyalgia, muscle spasms, pain, allergies, and sinus and respiratory tract infections. A number of other disease states, including angina and hyperthyroidism, have also shown promising results to IV vitamin infusions. Many people are also using IV vitamin therapy for quick rehydration after an intense sporting event, such as running a marathon, to cure a hangover, or for improved skin clarity.
LS: Traditionally, people who aren’t able to eat enough food, or who have an illness that interferes with nutrient absorption would be good candidates for IV vitamin therapy. Other uses for IV vitamin drips include correcting dehydration after extreme exercise or alcohol intake, boosting the immune system, and increasing energy levels. However, it’s important to note that most healthy people are able to get enough of these nutrients from an appropriate, balanced diet, and the long- and short-term benefits of IV vitamin drips are questionable.
DS: The most popular reasons for IV vitamin treatment is to relieve stress, rid your body of toxins, balance hormones, boost immunity, and make you skin healthier. There are positive anecdotal claims of relief and rejuvenation, but there’s no hard evidence to support these claims. Vitamins used in the IVs are water soluble, so once your body uses what’s needed, it will excrete the excess through your kidneys into your urine.
