Patients need vitamin D which is normally produced in the skin in response to ultraviolet light from the sun. Vitamin D is important for calcium absorption and good bone health. Physicians have been using sunscreens to protect patients from skin cancer and the aging effects of sunlight for a least a half a century. Dermatologists have promoted sunscreen use to restrict sunlight exposure especially in white Caucasians. If this behavior is done 100% of the time when outdoors individuals may suffer from vitamin D deficiency. It is impossible to influence persons' behavior to wear sunscreens all the time when outdoors. With the use of sunless tanning agent (DHA), once a week, we can obtain a continuous sunscreen in the top layer of the skin that will not wash off, can't be removed with soap and water, or removed by perspiration. Under these circumstances we can answer the scientific question, will sunscreen use inhibit the production of vitamin D in the skin?

A lipid cofactor that is required for normal blood clotting. Several forms of vitamin K have been identified: VITAMIN K 1 (phytomenadione) derived from plants, VITAMIN K 2 (menaquinone) from bacteria, and synthetic naphthoquinone provitamins, VITAMIN K 3 (menadione). Vitamin K 3 provitamins, after being alkylated in vivo, exhibit the antifibrinolytic activity of vitamin K. Green leafy vegetables, liver, cheese, butter, and egg yolk are good sources of vitamin K.
An isomer of glucose that has traditionally been considered to be a B vitamin although it has an uncertain status as a vitamin and a deficiency syndrome has not been identified in man. (From Martindale, The Extra Pharmacopoeia, 30th ed, p1379) Inositol phospholipids are important in signal transduction.
A nutritional condition produced by a deficiency of VITAMIN D in the diet, insufficient production of vitamin D in the skin, inadequate absorption of vitamin D from the diet, or abnormal conversion of vitamin D to its bioactive metabolites. It is manifested clinically as RICKETS in children and OSTEOMALACIA in adults. (From Cecil Textbook of Medicine, 19th ed, p1406)
OXIDOREDUCTASES which mediate vitamin K metabolism by converting inactive vitamin K 2,3-epoxide to active vitamin K.
A family of phylloquinones that contains a ring of 2-methyl-1,4-naphthoquinone and an isoprenoid side chain. Members of this group of vitamin K 1 have only one double bond on the proximal isoprene unit. Rich sources of vitamin K 1 include green plants, algae, and photosynthetic bacteria. Vitamin K1 has antihemorrhagic and prothrombogenic activity.
