People are more health-conscious than ever before, leading to a continued increase in the consumption of vitamin supplements. Consumers should understand the various vitamins before eating them to confirm their needs.

London, UK (Merxwire) - According to statistics from Grand View Research, the global vitamin supplements market size was valued at USD 44.12 billion in 2020 and is expected to expand at a compound annual growth rate (CAGR) of 6.2% from 2021 to 2028. Vitamin products are popular, but do you know the relationship between various vitamins and the human body?

Modern people eat more meat and fewer vegetables. In the case of unbalanced nutrition, people will take in micronutrients through vitamin supplements. The human body needs 13 kinds of vitamins, including 4 kinds of fat-soluble vitamins (vitamins A, D, E, K) and 9 kinds of water-soluble vitamins (8 types of vitamin B, vitamin C).

Vitamin A

Vitamin A has been proven to support the functions of tissues, skin, mucous membranes, immunity, and reproduction. Vitamin A is good for eyesight, and it is an important component of the eye's retina. In addition, pregnant women also need to supplement an appropriate amount of vitamin A to provide embryo development.

Vitamin A intake sources: Carrots, leafy greens, liver.

Vitamin B

8 types of vitamin B are B1, B2, B3, B5, B6, B7, B9, B12. Vitamin B complex plays an important role in cell metabolism and the synthesis of red blood cells. Each type of vitamin B is a cofactor involved in the metabolic process. They help regulate metabolism, maintain skin and muscle health, and enhance immune system and nervous system functions.

Vitamin B intake sources: Grains, meat, nuts.

Vitamin C

Vitamin C is one of the familiar vitamins. It is a vitamin found in various foods and is also an antioxidant. If the body's vitamin C is insufficient, it may cause scurvy. Vitamin C is an important component involved in tissue repair, helps skin cell proliferation, and supports the production of collagen, which helps wound healing and reduces wrinkles.

Vitamin C intake sources: Oranges, strawberries, green vegetables.

Vitamin D

Vitamin D and calcium are both important ingredients for maintaining bone health. Vitamin D can promote the balance and metabolism of calcium in the human body and help prevent rickets and osteomalacia. In addition, vitamin D also helps neuromuscular function, reduces inflammation, and affects the number of cells.

Vitamin D intake sources: Sunlight, fatty fish, egg yolks.

Vitamin E

Vitamin E is an important antioxidant. It is beneficial to immune function and cardiovascular health and can reduce the damage of reactive oxygen species to cell membranes. Vitamin E is also known as Tocopherol. It can be supplemented after a lack of vitamin E to promote hormone secretion, improve fertility, and prevent miscarriage.

Vitamin E intake sources: Nuts, plant oils, leafy greens.

Vitamin K

Vitamin K is the key to supporting the normal blood clotting process. It is related to proteins that regulate blood clotting. Without vitamin K, blood clotting will be severely impaired, and uncontrollable bleeding will occur. Studies have also shown that vitamin K is related to bone health. A lack of vitamin K may weaken bones and potentially lead to osteoporosis.

Vitamin K intake sources: Spinach, kale, tomatoes.

Although vitamins are not like carbohydrates, protein and fat can produce energy, but they can adjust the metabolism of organisms, so people must take proper amounts of vitamins to maintain health. Although the lack of vitamins in the organism can cause serious health problems, excessive intake of vitamins may cause symptoms such as nausea, vomiting, and headaches. Therefore, people must pay special attention to the intake when using vitamin supplements and take vitamins from food as much as possible.
