She’s helping those living the good life to live longer.
Dr. Amanda Kahn, an internist specializing in longevity, has become the “it girl” doctor for New York’s social set.
Notables such as actress Jenny Mollen and reality star-turned-wellness mogul Lo Bosworth pay $1,500 a month or $800 for a single visit to the concierge doctor.
She does everything from prescribe Ozempic — often in trendy microdoses for those looking to increase energy and reduce joint pain — and administer buzzy NAD+ injections, which are purported to help with everything from jet lag to inflammation.
“I focus on anti-aging from the inside out, at a cellular level,’’ Kahn told The Post.
With her smooth skin and shiny hair, Kahn looks younger than her 36 years, making her something of a walking billboard for her practice.
But the native Upper East Sider — who went to tony Nightingale-Bamford, did her undergrad at Columbia University, and med school at New York Presbyterian-Weill Cornell — wasn’t always the picture of health.
While pregnant seven years ago, she developed preeclampsia, a potentially fatal complication characterized by high blood pressure, and a number of other serious issues.
“I had an auto immune condition on the severe end of the spectrum, where my liver started to fail,” said Kahn, whose husband is an eye doctor.
After giving birth to their son, she struggled with constant headaches, joint pain and losing the 60 pounds she gained while pregnant.
“I didn’t bounce back easily,’’ Kahn said.
Traditional doctors were of little help. “They would say everything looked fine and throw out terms like fibromyalgia or chronic fatigue syndrome, but I felt brushed off,” she said.
Ultimately, she ended up turning to a number of “cutting edge alternatives,” including hyperbaric oxygen therapy, red light therapy, NAD+, the antioxidant glutathione, peptides and Pilates.
She also turned to Ozempic to lose the stubborn baby weight — making her an early adopter of using the diabetes medication for weight loss.
These days, Kahn who still uses many of those alternative treatments, along with taking Metformin — an oral medicine typically prescribed for Type 2 diabetes that may have anti-aging benefits — is the picture of health.
“I feel a lot better now than when I was in my twenties,’’ said the physician, who has also talked about starting preventative Botox in her 20s.
Her new patients usually begin by getting a full-body MRI, cancer and genetic blood tests and an in-depth blood panel, which typically total about $3,000 out-of-pocket. Some of the most common issues she sees in screenings are high mercury levels from fish consumption and low testosterone.
Her patients aren’t limited to millennial women, many are older and she has plenty of men coming in — though they’re less likely to post about it on Instagram
“I have former Olympic athletes and men with testosterone issues, but the men don’t post or talk about it much,’’ she said. “My patients in their 70s and 80s are trying to reverse some of the aging issues like- arthritis, and there are patients who have a family history of Alzheimers, who want to be proactive about their cognitive health.’’
Soho resident Daniele Chemla, the 68-year old designer behind the brand Avenue Montaigne, has been a patient for six months. She’s been getting peptides from Kahn.
One of the doctor’s more popular treatments is “stacking” peptides — getting different injections of the short-chain amino acids to help increase immunity, boost one’s metabolism, increase energy, stimulate collagen production and more.
For Chemla, it’s been a gamechanger.
“I am traveling and have to keep up my mental focus, and now I have much more energy,’’ she said. “I was exhausted in May and June, but now, after a whole day of a [photo]shoot, I came home, did laundry and then went out shopping!”
Kahn cautions that peptides are relatively new treatments that should only be administered under the care of a trusted physician and sourced from reputable pharmacies.
But, when used properly, she said they have the potential to greatly benefit patients, especially Gothamites burning the candle at both ends.
“Most of us in New York work very hard, so there is psychosocial stress that can age your cells,” she said. “We use soft tissue regenerative peptides that are very cutting edge and can rebuild collagen and elastin, so I am helping [patient’s] faces as well as their bodies. They are stacking their Cartier bracelets, and now they are stacking their longevity meds! ’’
