Provitamin

From WikiMD's Wellness Encyclopedia

Provitamins are substances that can be converted within the body into active vitamins. They are considered to be precursors to essential vitamins, playing a crucial role in maintaining overall health and well-being. Provitamins are typically found in various foods and dietary supplements, providing a natural source of essential nutrients that the body needs to function properly.

One of the most well-known provitamins is beta-carotene, which is a precursor to vitamin A. Beta-carotene is commonly found in orange and yellow fruits and vegetables such as carrots, sweet potatoes, and squash. Once consumed, the body converts beta-carotene into vitamin A, which is essential for maintaining healthy vision, skin, and immune function.

Another important provitamin is 7-dehydrocholesterol, which is converted into vitamin D when exposed to sunlight. Vitamin D plays a crucial role in calcium absorption and bone health, as well as supporting immune function and overall well-being. Sources of 7-dehydrocholesterol include fatty fish, egg yolks, and fortified dairy products.

Provitamin B5, also known as pantothenic acid, is a precursor to coenzyme A, which is involved in various metabolic processes within the body. Pantothenic acid is found in a wide range of foods, including meat, dairy products, and whole grains. It plays a key role in energy production, hormone synthesis, and overall cellular function.

In addition to these examples, there are many other provitamins that play essential roles in maintaining health and preventing nutrient deficiencies. By including a variety of provitamins in your diet, you can ensure that your body has an adequate supply of essential nutrients to support overall well-being.
