vitaminës

Vitaminës are a collection of organic compounds essential for various metabolic processes in humans. Although classified collectively as vitamins, they encompass a diverse group of molecules that share the common role of supporting health, growth, and development. These nutrients are required in small quantities and must often be obtained through diet, as the body either cannot produce them sufficiently or at all.

There are multiple types of vitaminës, each with specific functions. For example, vitamin A is vital for vision, immune function, and skin health; vitamin D promotes calcium absorption and bone health; vitamin E acts as an antioxidant, protecting cells from damage; and vitamin K is crucial for blood clotting. The B-complex group, including B1 (thiamine), B2 (riboflavin), B3 (niacin), B5 (pantothenic acid), B6 (pyridoxine), B7 (biotin), B9 (folate), and B12 (cobalamin), assist in energy production, red blood cell formation, and neurological health.

Deficiency in vitaminës can lead to various health issues. For instance, lack of vitamin C can cause scurvy, while insufficient vitamin D may result in rickets or osteomalacia. Adequate intake of vitaminës is generally achieved through a balanced diet that includes fruits, vegetables, grains, dairy, and protein sources.

Because vitaminës are water-soluble or fat-soluble, their absorption, storage, and excretion vary. Water-soluble vitamins, such as B-complex and vitamin C, are not stored in large amounts and excess is excreted in urine; fat-soluble vitamins (A, D, E, and K) can be stored in adipose tissue and liver, potentially leading to toxicity if consumed excessively.

Overall, vitaminës play an essential role in maintaining health and preventing nutrient deficiency diseases around the world.
