What is it?

Vitamin D3, also known as cholecalciferol, is an essential nutrient that plays a crucial role in maintaining bone health and promoting immune system function. It is a fat-soluble vitamin that is naturally synthesized by the body when the skin is exposed to sunlight. Vitamin D3 is also found in some foods, such as fatty fish, egg yolks, and fortified dairy products. Adequate levels of vitamin D3 are important for calcium absorption and utilization, which is necessary for strong bones and teeth. Additionally, research has shown that vitamin D3 may also have a positive impact on other aspects of health, including reducing the risk of certain diseases, such as heart disease, diabetes, and some types of cancer. While many people can get enough vitamin D3 through sunlight and a balanced diet, some individuals may require supplementation to maintain optimal levels.

Asthma is a condition in which your airways narrow and swell and may produce extra mucus. This can make breathing difficult and trigger coughing, a whistling sound (wheezing) when you breathe out and shortness of breath.



For some people, asthma is a minor nuisance. For others, it can be a major problem that interferes with daily activities and may lead to a life-threatening asthma attack
