Dermatologist Dr. Olga Chubo stated that it is impossible to obtain a sufficient amount of vitamin D, even with frequent exposure to sunlight.
According to her, this is because vitamin D production by the sun only occurs when the skin is reddened, and slows down once it has tanned.
She says: "Furthermore, we must not overlook the need to limit exposure to direct sunlight. Because excessive exposure to ultraviolet radiation poses a serious risk of skin cancer. Also, limiting exposure to sunlight reduces the efficiency of producing this vitamin. As we age, the skin's ability to produce it weakens, so it is impossible to compensate for the deficiency by exposure to sunlight alone. This is a myth."
According to her, vitamin D can be obtained from food; it is found in raw egg yolks, some types of mushrooms, cheese, cottage cheese, butter, as well as fermented dairy products, fatty fish, and seafood. However, a balanced diet alone is not enough to compensate for a deficiency, as modern, industrially produced foods are often lacking in this vitamin.
In addition, chronic inflammation or stress can rapidly deplete vitamin D stores because they cause oxidative stress, which requires the body to produce high levels of antioxidants to combat it. Vitamin D is one of the most powerful antioxidants, working to neutralize free radicals.
She says: "It is important to remember that only a doctor can prescribe a treatment regimen and an appropriate dosage for vitamin D deficiency. If necessary, it is preferable to choose vitamins in liposomal form, as they penetrate cell membranes easily and resist oxidative stress in the stomach."
