There is no standard protocol to prevent aging, no single treatment that doctors and scientists agree can turn back our biological clocks – at least not yet.
Some biohackers have tried expensive injections of plasma collected from young people that cost thousands of dollars, while other researchers say the benefits of regular and consistent exercise and a healthy diet are unmatched.
But if there was one anti-aging method that almost everyone who invests in longevity, studies aging, or personally deals with aging can agree on, vitamin D might be it, according to Business Insider.
Immune expert Dr. Anthony Fauci, anti-aging researcher Joao Pedro de Magalhaes and billionaire longevity investor Christian Angermayer told Insider that they take vitamin D supplements in different doses and at different times of the year.
Angermayer said this is “one of the really proven things” people can do to slow the aging process, in part because of the beneficial effects vitamin D can have on the immune system and cancer risk.
Vitamin D helps absorb calcium – which reduces the degree of inflammation in the body
Vitamin D helps our intestines absorb calcium from food, keeping our bones healthy and strong. When we don’t absorb enough calcium from food, our body calls on the calcium stored in our bones to meet its needs.
Studies have consistently shown that older adults who take vitamin D supplements (ranging from 400 to 800 international units per day) significantly reduce their risk of bone fractures; this is a particularly important result for the elderly, who face an increased risk of death from injuries such as hip fractures.
Vitamin D is also known to help prevent muscle cramps and spasms, reduce inflammation and improve immune function.
Children and adults up to the age of 69 have, from a technical point of view, the same daily amount of vitamin D recommended in the USA (600 IU).
Dr. John Bilezikian, an endocrinologist at Columbia University Medical Center, said that for most people, about 15-20 minutes of sun exposure during the summer months should be enough.
Fatty fish such as salmon or tuna, as well as (to a lesser extent) beef, milk and egg yolks can also help replenish your vitamin D stores. If you already have enough of it in your diet, you may not need a supplement at all.
But there are some groups of people who should consider taking vitamin D supplements year-round, including: older adults (who can’t absorb vitamin D as well as others), people who aren’t exposed to regularly in the sun or who do not eat enough foods rich in vitamin D, people with darker skin (which can make it more difficult to absorb vitamin D from the sun).
Experts recommend that, once people reach the age of 70, they increase their intake of vitamin D to 800 IU daily.
But do not exaggerate the intake of vitamin D – too much intake can lead to the dangerous accumulation of calcium in the kidneys, heart, blood and lungs. The safe upper limit is 4,000 IU per day, according to The National Institutes of Health.
Biohacker Bryan Johnson (the tech entrepreneur who injected his own son’s blood), 46 years old, takes 2,000 IU of D3 every morning, according to his website. Angermayer, the 45-year-old billionaire investor, takes about 4,000 IU every three days. Fauci, 82, did not tell Insider exactly how much vitamin D he takes, but said his levels, which were “low” before he started taking supplements, have become “normal.”
De Magalhaes doesn’t worry too much about her vitamin D intake in the summer, but in the winter she adds vitamin D supplements to her simple and “moderately healthy” anti-aging regimen – along with regular exercise, no smoking and very little alcohol or unhealthy food.
“I’m not doing gene therapy in my garage or anything,” de Magalhaes told Insider. “You have to find that balance between enjoying life and living healthy that will statistically – most likely – allow you to live longer.”
