Vitamin D is an essential nutrient that plays a crucial role in various aspects of human health. It is unique because it can be synthesized by the body through exposure to sunlight, as well as obtained from certain foods and supplements. In this comprehensive review, we will explore the secrets of vitamin D, including its sources, functions, benefits, deficiency risks, and optimal levels. Sources of Vitamin D: Sunlight: When the skin is exposed to sunlight, it synthesizes vitamin D3 (cholecalciferol) from cholesterol. Diet: Some food sources naturally contain vitamin D, such as fatty fish (salmon, mackerel), cod liver oil, and egg yolks. Additionally, fortified foods like milk, orange juice, and cereals often contain added vitamin D. Forms of Vitamin D: Vitamin D3 (cholecalciferol): Synthesized in the skin and also found in animal-based food sources. Vitamin D2 (ergocalciferol): Derived from plant-based sources or fungal sources like mushrooms. Functions and Benefits of Vit...

Acute fatigue is defined as lasting one month or less, subacute fatigue as lasting between one and six months, and chronic fatigue as lasting ov...
Smoking is a major public health issue, responsible for an estimated 6 million deaths worldwide each year (WHO, 2021). Despite the well-known health risks of smoking, many individuals continue to smoke, and smoking cessation remains a top public health priority. In this review, we provide an overview of current approaches to smoking cessation management in adults, including pharmacotherapy, behavioral interventions, and the use of mobile health technologies. We also discuss future directions for smoking cessation management, including the potential use of personalized medicine, the integration of digital health tools, and the incorporation of social determinants of health into smoking cessation interventions. Pharmacotherapy: The use of pharmacotherapy for smoking cessation is well-established, and several classes of medications have been approved by regulatory agencies for this indication. Nicotine replacement therapy (NRT), such as nicotine gum or patches, is a commonly used form of...
