Vitamin A deficiency can cause keratomalacia.

Thiamine (vitamin B1) deficiency causes beriberi and Wernicke–Korsakoff syndrome.

Riboflavin (vitamin B2) deficiency causes ariboflavinosis.

Niacin (vitamin B3) deficiency causes pellagra.

Pantothenic acid (vitamin B5) deficiency causes chronic paresthesia.

Vitamin B6Biotin (vitamin B7) deficiency negatively affects fertility and hair/skin growth. Deficiency can be caused by poor diet or genetic factors (such as mutations in the BTD gene, see multiple carboxylase deficiency).

Folate (vitamin B9) deficiency is associated with numerous health problems. Fortification of certain foods with folate has drastically reduced the incidence of neural tube defects in countries where such fortification takes place. Deficiency can result from poor diet or genetic factors (such as mutations in the MTHFR gene that lead to compromised folate metabolism).

Vitamin B12 (cobalamin) deficiency can lead to pernicious anemia, megaloblastic anemia, subacute combined degeneration of spinal cord, and methylmalonic acidemiaamong other conditions.Vitamin C (ascorbic acid) short-term deficiency can lead to weakness, weight loss and general aches and pains. Longer-term depletion may affect the connective tissue. Persistent vitamin C deficiency leads to scurvy.

Vitamin D (cholecalciferol) deficiency is a known cause of rickets, and has been linked to numerous health problems.Vitamin E deficiency causes nerve problems due to poor conduction of electrical impulses along nerves due to changes in nerve membrane structure and function.

Vitamin K (phylloquinone or menaquinone) deficiency causes impaired coagulation and has also been implicated in osteoporosis
