Vitamins are organic substances that are crucial for maintaining good health and wellbeing. They are received through the diet or supplements since the body needs a minimal amount of them and cannot manufacture enough of them. Vitamins are essential for many body functions, such as immune system function, metabolism, growth, and development.

There are 13 essential vitamins, which are divided into the water-soluble vitamins (B vitamins and vitamin C) and the fat-soluble vitamins (A, D, E, and K). Water-soluble vitamins are not significantly stored in the body and are eliminated in the urine, whereas fat-soluble vitamins are stored in the body's fatty tissues and liver.

Each vitamin has a distinct purpose, and deficiencies in any vitamin can result in a variety of health issues. As an important aspect of the human life, I will look at the essential vitamins, their functions, dietary sources and deficiency.

Deficiency: Rare, but may result in hair loss, skin rash, and neurological symptoms

VITAMIN B9 (FOLIC ACID)

Dietary sources: Leafy greens, legumes, broccoli and other cabbage-family greens, fortified grains, liver, leafy vegetables, peas, liver, sunflower seeds, asparagus, beets, brewer's yeast, lentils, oranges, wheat germ, peanuts. Several fruits have moderate amounts

Deficiency: Anemia. During pregnancy, this can affect the fetus’s nervous system. Doctors do recommend folic acid supplements before and during pregnancy.

Functions: It helps maintain nerve cells and important for red blood cell formation

Dietary sources: Animal products (meat, fish, dairy), fortified cereals, fish, shellfish, poultry, eggs, fortified soy products, fortified nutritional yeast.

Deficiency: Pernicious anemia, nerve damage, dementia.

VITAMIN C (ASCORBIC ACID)

Functions: It contributes to collagen synthesis, wound healing, and bone formation. It also strengthens blood vessels, supports the immune system, helps the body absorb iron, and acts as an antioxidant.

Dietary sources: Citrus fruits, including oranges, lemons, limes and grapefruit,

VITAMIN SUPPLEMENTS

Vitamin supplements are a common approach for people to make sure they are getting enough nourishment. The body requires vitamins in modest amounts in order to function effectively. While vitamins can be obtained from a healthy diet, many individuals also take vitamin supplements to increase their intake of other nutrients.

One of the key advantages of vitamin supplements is that they might help people who may have nutritional deficiencies in their diet. For instance, since vitamin B12 is mostly found in animal-based diets, vegetarians and vegans may need to take supplements. Prenatal vitamins, which provide larger amounts of certain nutrients, may also be beneficial for expectant mothers.

However, vitamin supplements should not be used as a substitute for a healthy diet. While they can help to fill nutritional deficiencies, they cannot replace the wide range of nutrients that come from eating a variety of foods. In addition, taking high doses of certain vitamins can be harmful to the body, especially if they are fat-soluble vitamins that can accumulate in the body over time. For example, excessive intake of vitamin A can lead to liver damage and birth defects.

It is important to note the not all vitamin supplements are produced equally. Some supplements could include inferior or synthetic vitamin forms, which the body might not be able to absorb as readily as the natural forms present in food. It's critical to select dietary supplements from reliable manufacturers who employ high quality vitamins, and that they have passed all the regulatory requirements.

Vitamin supplements can be a helpful tool for completing nutritional deficiencies in one's diet, however, they should NOT be used as a replacement for a nutritious and well-balanced diet. It's crucial to select supplements of the highest caliber from reliable suppliers and to refrain from consuming excessive amounts of particular vitamins. Before beginning a new vitamin regimen, it's recommended that you consult with a healthcare professional.
