A Hollywood health craze of receiving vitamins through intravenous drip has spread to New York City, as many of Manhattan's elite go to doctors to get a concoction of nutrients, believing they boost their energy levels.
Some pay up to $1,000 for a session, going on lunch breaks or after work and spending up to three hours in the chair.
While the FDA has not approved them as medical treatments, many stand by the alleged benefits they receive from the IVs.
Dr. Marcia Harris, a gynecologist in midtown east, said she has seen a spike in the amount of requests for vitamin IV concoctions.
Harris said celebrities, like Simon Cowell, helped make the IV drips popular. Cowell gets a weekly drip of B12, magnesium and vitamin C for his liver.
One avid fan of IV drips is Cristina Andrews, 48, who gets one once a month.
"I come for two hours, sometimes three, because I like to take them slow," she said. She said she spends $130 on each treatment and feels fatigue afterward, but the next day feels she can do anything.
Dr. Jeffrey Morrison said it started becoming popular five years ago when it was revealed that some basketball players use them.
"It's basic biochemistry, when the body has its building blocks, it works better," Morrison said.
He said weekly drips are the best, especially during stressful times.
He said the most common drip he gives is the "Myers Cocktail" which is made up of calcium, trace mineral selenium, vitamin C and B-complex.
Vanessa Artega said she gets the Myers Cocktail because it prevents her from getting sick, and Lisa Carrion said she gets it because it makes her feel more invigorated.
While many doctors now offer the drips, critics say there are little health benefits.
"There has never been any randomized controlled clinical trials to demonstrate any benefit to these IV infusions whatsoever," Dr. Kevin Campbell said. "Although I think that certain groups of people may benefit (those with documented deficiencies of a particular vitamin or mineral) widespread use of this technique is unfounded and expensive."
He believes any benefits the patients seem to feel from the drips is due to the placebo effect.
"As a cardiologist, I would not recommend these types of treatments. Our time can be better spent on preventative activities such as diet and exercise and modification of risk factors."
