Vitamin A
Vitamin A is a fat-soluble vitamin that is good for healthy vision, skin, bones and other tissues in the body. Vitamin A often works as an antioxidant, fighting cell damage, but it also has many other uses. A deficiency in vitamin A can cause serious illness but ingesting too much can be toxic and lead to major problems. Vitamin A deficiency may exacerbate low iron status, which can lead to anemia. Other symptoms of vitamin A deficiency include dry skin, bumpy skin, hair loss, and increased severity and mortality risk of diarrhea and measles. The Recommended Dietary Allowance (RDA) for men and women is 900 and 700 μg retinol activity equivalents (RAE)/day, respectively. The Tolerable Upper Intake Level (UL) for adults is set at 3,000 μg/day of preformed vitamin A.


Beta Carotene
The human body converts beta carotene into vitamin A (retinol) - beta carotene is a precursor of vitamin A. We need vitamin A for healthy skin and mucus membranes, our immune system, and good eye health and vision. Beta carotene, like all carotenoids, is an antioxidant. Deficiency has been associated with abnormal visual adaptation to darkness (night blindness), dry skin, decreased resistance to infections, and other symptoms. While there is a recommended dietary allowance (RDA) for vitamin A, there is no RDA for beta-carotene specifically. Studies have used dosages ranging between 15 and 180 milligrams a day.

Niacin
Niacin, also called nicotinic acid, is a B vitamin (vitamin B3) used in vitamin supplements and in combination with prescription drugs. It is most often used to prevent cardiovascular disease. Niacin has a wide range of uses in the body, helping functions in the digestive system, skin and nervous system. Niacin, a name coined from nicotinic acid vitamin, comes in several forms, including niacinamide (nicotinamide) and inositol hexanicotinate . Pellagra is a disease caused by a lack of the vitamin niacin (vitamin B3). Symptoms include inflamed skin, diarrhea, dementia, and sores in the mouth.

Vitamin B6
Vitamin B6 is a water-soluble vitamin that is naturally present in many foods. Vitamin B6 in coenzyme forms performs a wide variety of functions in the body and is extremely versatile, with involvement in more than 100 enzyme reactions, mostly concerned with protein metabolism. Vitamin B6 also plays a role in cognitive development through the biosynthesis of neurotransmitters and in maintaining normal levels of homocysteine, an amino acid in the blood. Vitamin B6 deficiency is associated with microcytic anemia, electroencephalographic abnormalities, dermatitis with cheilosis (scaling on the lips and cracks at the corners of the mouth) and glossitis (swollen tongue), depression and confusion, and weakened immune function.

Vitamin B6 (continued)
Some people use vitamin B6 for boosting the immune system, eye infections, bladder infections, tooth decay, and preventing polyps, cancer, and kidney stones. Vitamin B6 is also used for Alzheimer's disease and other types of dementia or memory loss, attention deficit-hyperactivity disorder (ADHD), Down syndrome, autism, diabetes and related nerve pain, sickle cell anemia, migraine headaches, asthma, carpal tunnel syndrome, night leg cramps, muscle cramps, arthritis, preventing fractures in people with weak bones, allergies, acne and various other skin conditions, and infertility. The RDA is Children 9-13 years, 1 mg; Males 14-50 years, 1.3 mg; Males over 50 years, 1.7 mg; Females 14-18 years, 1.2 mg; Females 19-50 years, 1.3 mg
Folate
Folate, or vitamin B9, is one of many essential vitamins. Folate is important because it plays a role in DNA synthesis and repair. It encourages cell and tissue growth. Folate is found mainly in dark green leafy vegetables, beans, peas and nuts. Fruits rich in folate include oranges, lemons, bananas, melons and strawberries. The synthetic form of folate isfolic acid. Folate health benefits includes reducing risk of heart disease, promoting health and function of brain, fostering positive mood and preventing depression. Mean dietary intakes of folate (including food folate and folic acid from fortified foods and supplements) range from 454 to 652 micrograms per day in U.S. adults and from 385 to 674 micrograms in children. Keep in mind that adults need about 400 micrograms daily, and children need roughly 300 micrograms.
Folate deficiency is the lack of folic acid in the blood. Low levels can cause megaloblastic anemia. Anaemia is where you have fewer red blood cells than normal or you have an abnormally low amount of a substance called haemoglobin in each red blood cell. General symptoms of anaemia may include: extreme tiredness (fatigue), lack of energy (lethargy), loss of appetite and weight loss, & headaches.
Deficiency of Folate leads to Anaemia which is where you have fewer red blood cells than normal or you have an abnormally low amount of a substance called haemoglobin in each red blood cell. General symptoms of anaemia may include: extreme tiredness (fatigue), headaches, pale skin, loss of appetite and weight loss, and lack of energy (lethargy).

Vitamin B12
Vitamin B12 is required for proper red blood cell formation, neurological function, and DNA synthesis Vitamin B12 does a lot of things for your body. It helps make your DNA and your red blood cells, for example. Since your body doesn't make vitamin B12, you have to get it from animal-based foods or from supplements. And you should do that on a regular basis, because your body doesn’t store vitamin B12 for a long time, The RDA is Teens age 14-18: 2.4 mcg and Adults: 2.4 mcg . If you have vitamin B12 deficiency, you could become anemic. A mild deficiency may cause no symptoms.

Biotin
Biotin is a water-soluble B-vitamin that helps your body convert food into energy metabolism. Deficiency is quite rare, although it has been associated with the long-term consumption of raw eggs. There isn't a good laboratory test for detecting biotin deficiency, so this condition is usually identified by its symptoms, which include thinning of the hair (frequently with loss of hair color) and red scaly rash around the eyes, nose, and mouth. Nervous system symptoms include depression, exhaustion, hallucinations, and tingling of the arms and legs. There is some evidence that diabetes could result in biotin deficiency. Biotin is an important component of enzymes in the body that break down certain substances like fats, carbohydrates, and others.

Vitamin C

Vitamins are substances that your body needs to grow and develop normally. Vitamin C is an antioxidant. It is important for your skin, bones, and connective tissue. It promotes healing and helps the body absorb iron. Its a water-soluble vitamin and it helps the body form and maintain connective tissue, including bones, blood vessels, and skin. For adults, the recommended daily amount for vitamin C is 65 to 90 milligrams (mg) a day, and the upper limit is 2,000 mg a day. Although too much dietary vitamin C is unlikely to be harmful, megadoses of vitamin C supplements might cause Diarrhea & Nausea.
