Vitamin A and Vitamin E are the 2 i know of.
Vitamin D.
Vitamin D, of course.
Vitamin D
Because it is manufactured in the skin in the presence of sunshine.
Vitamin D has two forms which are vitamin D2 (ergocalciferol) and vitamin D3 (cholecalciferol). Vitamin D without a subscript refers to either D2 or D3 or both.Vitamin D3 is produced in the skin of vertebrates after exposure to ultraviolet B light.
Vitamin D is the vitamin that is synthesized by the skin. This is why it is also referred to as the 'sunshine vitamin'. Vitamin D deficiency can occur due to factors that will lead to reduced exposure to sunlight. Some of these are: Dark-skinned people, application of too much sunscreen, prolonged winter months, housebound people due to age or illness. An sunshine exposure of at least 45-60 minutes per day is considered adequate to prevent vitamin D deficiencies which include bone deformities like rickets among other health complications. It is important to include a balanced diet to achieve greater health.
Vitamin D? No. Vitamin D is not manufactured, rather, it is chemically altered by UV rays on the skin, and thereby, capable of utilization by the liver, and then by the kidneys; the organ responsible for maintenance of calcium levels. Interestingly enough, however, the active form of vitamin D is plentiful in the western diet, and only about 5-10% of vitamin D is actually utilized by the UV ray induced alteration from the skin. The skin produces many substances, however, most substances are consider paracrine (affecting neighboring cells) rather than endocrine (affecting distant organ systems). More commonly, hormones or endocrine substances, affect the skin, causing pathologic states. An example of paracrine: - Inflammatory markers- Sites of trauma, or areas of potential infection; cells within the skin induce several chemicals that increase the migration of specialized cells of the immune system, as well as cells from the vasculature (platelts) and other cells that are responsible for healing - Endocrine: Insulin (acanthosis nigricans) immune complexes (vitiligo, bullae)
The vitamin that is best for skin is Vitamin E. This can help with skin diseases, and can even help to prevent skin cancer in those with skin diseases.
vitamin E
People who live in the north have a decreased amount of sunlight exposure. Vitamin D is manufactured by skin cells when exposed to sunlight, and is needed for absorption of dietary calcium.
The Sun causes the synthesis of Vitamin D in the skin.
Vitamin D is synthesized in the skin with the help of sunlight.
