food sources of Vitamin A are
fish liver oils, egg yolks, butter, cream, and dark yellow/orange fruits and vegetables (carrots, yams, apricots, squash, cantaloupe)
Vitamin D contributes to
utilization of calcium and phosphorus, and aids in skin repair

excess consumption of vitamin D can result in
hypercalcemia
sunlight enables the body to
synthesize vitamin D
Vitamin D food sources are

preserve muscles and red blood cells, maintain the myelin sheath
Vitamin E deficiency results in
hemolytic anemia, affects the nerve fibers that influence walking and vision
Vitamin E food sources are
vegetable oils and certain nuts
Vitamin K contributes to
blood clotting and bone maintenance
Vitamin K deficiency results in
increased bleeding time
Vitamin K food sources are
some oils, liver, leafy green vegetables (spinach, broccoli, cabbage)

leafy green vegetables
Thiamin B1 aids in
proper digestion, peristalsis, provides energy to smooth muscles, glands, the CNS, and blood vessels
thiamin deficiency results in
beriberi, gastrointestinal symptoms, cardiovascular problems
thiamin is found in
in almost all plant and animal tissues, especially meat, grains, and legumes
riboflavin B2 aids in
growth and tissue healing
riboflavin deficiency results in

pantothenic acid B5 aids in
biological reactions (energy production, catabolism, synthesis of fatty acids, phospholipids, cholesterol, steroid hormones, neurotransmitters acetylcholine)
pantothenic acid deficiency results in
anemia, CNS changes, deficiency unlikely due to diverse availability of foods available
pantothenic acid is found in
organ meats, egg yolk, avocados, cashew, nuts and peanuts, brown rice, soy, lentils, broccoli, milk
