Vitamin D deficiency is mainly supplemented by sun exposure, medication such as vitamin D drops, and food supplements.
1. Sunbathing: 7-dehydrocholesterol, a precursor of vitamin D biosynthesis, exists in human skin and can be converted into cholecalciferol, endogenous vitamin D₃ (a type of vitamin D), after exposure to ultraviolet light from the sun. Keep the sun exposure time at 30 minutes each time, and avoid direct sunlight to avoid skin damage.
2. Drug supplementation: Oral vitamin D drugs such as vitamin D drops, calcium carbonate D₃ tablets, and calcitriol can be taken under the guidance of a doctor to supplement vitamin D effectively.
3. Food supplementation: Pay attention to the diversity of food and the combination of meat and vegetables in the diet, and increase the intake of vitamin D-rich food, such as deep-sea fish, animal liver, etc., which is conducive to nutritional balance and vitamin D supplementation.
If diagnosed with vitamin D deficiency, patients should choose the appropriate method of supplementation under the guidance of a doctor, and should not take medication on their own, otherwise adverse reactions may occur. The above medication should be taken in accordance with medical advice.
