Transcript of VITAMINS: Water Soluble
WATER SOLUBLE VITAMIN
Vitamin B1 (Thiamine),antineuretic factor, anti-beri-beri factor
Functions: It plays an important role in helping the
body metabolize carbohydrates and fat to produce energy.
It is essential for normal growth and development and helps to maintain proper functioning of the heart and the nervous and digestive systems.
SOURCES: Green peas, Spinach, liver, Beef, Pork, Navy
beans, Nuts, Pinto beans, Bananas, Soybeans, Goji berries, Whole-grains, Breads, Yeast, Aleurone layer of unpolished rice, Legumes
TOXICITY: Large doses (5,000 to 10,000 mg) can cause
headaches, irritability, rapid pulse, and weakness.
DEFICIENCY: Wernicke-Korsakoff syndrome Beriberi neurodegeneration ABSORPTION:
- upper & lower small intestine, some are in the liver, heart, kidney
Vitamin B2 (Riboflavin,vitamin
G,lactoflavin,hepatoflavin,ovoflavin)
FUNCTIONS:It plays a key role in energy metabolism, and is
required for the metabolism of fats, carbohydrates, and proteins.
SOURCES: Cheese egg yolks almonds organ meats whole grains wild rice soybeans milk spinach mushrooms almonds poultry
TOXICITY:Riboflavin is not toxic when taken orally, as its low
solubility keeps it from being absorbed in dangerous amounts from the gut. Although toxic doses can be administered by injection, any excess at nutritionally relevant doses is excreted in the urine, imparting a bright yellow color when in large quantities.
DEFICIENCY: Ariboflavinosis Symptoms of significant deficiency syndromes include
sore throat, swelling of mucous membranes, mouth or lip sores, anemia, and skin disorders.
ABSORPTION:Most dietary riboflavin is efficiently absorbed by a
saturable carrier mechanism primarily in the proximal small intestine.
Vitamin B3 (Niacin,nicotinamide acid,pellagra-preventive factor)
FUNCTIONS: Energy Production Metabolism of Fats
SOURCES:~Animal products: liver, heart and kidney;
chicken; beef; fish: tuna, salmon; milk eggs
~ Fruits and vegetables: leaf, vegetables, broccoli, tomatoes, carrots , dates, sweet potatoes, asparagus, avocados
~ Seeds:nuts, whole grain products, legumes, saltbush seeds
~ Fungi: mushrooms brewer's yeast
TOXICITY:Due to high doses , effects:
an imbalance of other important B vitamins liver damage and stomach ulcers "niacin flush“
DEFICIENCY: First symptoms
Muscular weakness Inability to eat Indigestion Skin problems Canker sores Vomiting Depression
Worst form of deficiency Pellagra
ABSORPTION:Niacin is rapidly absorbed in the proximal small
intestine by passive diffusion. Being a water-soluble vitamin it is not stored in the body. Niacin can be synthesized from tryptophan with vitamins B1, B2, and B6 as essential cofactors.
Vitamin B5 (Panthothenic Acid )
OTHER NAME: “Anti-Stress vitamin” FUNCTIONS:
Assists in the metabolism of carbohydrates, proteins and fatty acids.
Essential for cell metabolism. Works in the synthesis of cholesterol metabolism,
hormone production and hemoglobin . SOURCES:
Peas and beans (except green beans) , lean meat, Organ meat (liver and kidney), Poultry, Fish, Shellfish, Yeast, Cauliflower, Kale, Broccoli, Tomatoes, Lobsters, Lentils, Avocado, Mushrooms, Sweet potatoes, Whole-grain cereals and bread, Sunflower seeds
TOXICITY:- Because the B5 vitamin is water soluble, toxicity is extremely uncommon.
- Vitamin could possibly cause diarrhea if the vitamin is taking in excessive amounts.
DEFICIENCY:- Paresthesia- Vitamin B5 deficiency causes depression, personality changes, heart problems, increased risk of infections, fatigue, abdominal pains, sleep disturbances, numbness and altered sensation in the arms and legs, muscle weakness, cramps, increased sensitivity to insulin, decreased blood cholesterol levels and decreased potassium levels in the body.
ABSORPTION:Vitamin B5 is easily absorbed from the intestines and
is distributed to all tissues in the body. The body does not break down Vitamin B5 and excretes large amounts of this vitamin in the urine.
Vitamin B6 (Pyridoxine ) FUNCTION:
Helping amino acid and protein metabolism Enabling red blood cell metabolism Helping the nervous system function efficiently Helping the immune system function efficiently Converting tryptophan (an amino acid) to niacin (a
vitamin) Enabling the breakdown of glycogen to glucose Aiding in the metabolism, transportation, and
distribution of selenium Assisting in the metabolism of calcium and magnesium
SOURCES: Fortified breakfast cereal Oatmeal, instant Potato, baked with skin Banana Chicken breast, roasted, no skin Garbanzo beans Tomato paste Pork loin, broiled Top sirloin, broiled Halibut, broiled Rainbow trout, cooked Brown rice, cooked Sweet potato, baked with skin Sunflower seeds, dry roasted Avocado Kidney beans, cooked Lentils, cooked Tuna Peanut butter Lima beans Soybeans, cooked
TOXICITY: Too much vitamin B6 can result in nerve
damage to the arms and legs. It can also result in increased urinary excretion of other B vitamins, leading to imbalances.
Symptoms of vitamin B6 toxicity include: Muscle incoordination Numbness of the hands and feet Impaired reflexes
Abnormal plasma amino acid levels
DEFICIENCY: Skin inflammation and irritation Glossitis (sore or inflamed tongue) Confusion Depression Irritability and nervousness Fatigue and sleepiness Convulsions Anemia (microcytic type)
ABSORPTION: Cheilosis (cracking and scaling of the lips) The forms of vitamin B6 found in food are converted
to active forms in the liver. Vitamin B6 is readily absorbed in the upper small
intestine by simple diffusion.
Vitamin B7 (Biotin)
OTHER NAME: Vitamin H, anti-eggwhite injury
factor FUNCTIONS:
It helps our body's cells produce energy. It does this by working with four essential
enzymes that break down fat, carbohydrate, and protein to yield energy.
Biotin also plays a role in the synthesis and function of DNA.
SOURCES: Eggs, Liver, yeast breads, whole grains, sardines,
legumes, mushrooms, cereals, cauliflower, peanuts, cheese
TOXICITY:There have been no reports of adverse effects due
to eating too much biotin. DEFICIENCY:
Abnormal heart action,dermatitis, enteritis,hair loss(alopecia),depression,muscle pain,weakness,fatigue,nausea
A biotin deficiency is rare in healthy people who eat a healthful diet, since we usually get enough from the bacteria living in our digestive tracts.
ABSORPTION:Biotin absorption takes place in the proximal small
intestine.
Vitamin B8 (Myo-Inositol) OTHER NAME:
Inositol, Inositol Monophosphate, and Inositol Hexaphosphate
FUNCTION: Inositol as the basis for a number of signaling and
secondary messenger molecules, is involved in a number of biological processes, including:
Insulin signal transduction Cytoskeleton assembly Nerve guidance (Epsin) Intracellular Calcium (Ca2+) concentration control Cell membrane potential maintenance Serotonin activity modulation Breakdown of fats and reducing blood cholesterol Gene expression
SOURCES: Fruits Beans Grains Nuts
TOXICITY:No toxic effects are known, but
diarrhea has been noted with the intake of very high dosage of inositol, as well as an increased secretion of creatine.
Fresh Vegetables oats and bran milk yogurt
DEFICIENCY: Inositol deficiency is not common. Deficiency symptoms that do occur, are:
constipation eczema elevated cholesterol levels hair loss
ABSORPTION: Inostiol has no known interactions with drugs.
However, when inositol combines with minerals, especially calcium, zinc, and iron, the phytic acid may hinder mineral absorption in the intestine.
Vitamin B9 (Folic Acid,folate,vitamin M,vitamin Bc,pteroylglutamic acid)
FUNCTIONS: Maintain healthy skin and muscle tone Enhance immune and nervous system function Promote cell growth and division — including that of the red
blood cells that help prevent anemia. Reduce the risk of pancreatic cancer
SOURCES: Leafy greens such as spinach and turnip greens Broccoli Asparagus Mushrooms Liver Dry beans and peas Fortified cereals and grain products Fortified juices
TOXICITY: High doses (above 15 mg) can cause:
stomach problems, sleep problems, skin reactions Seizures
DEFICIENCY: Deficiency results in a megaloblastic or macrocytic
anemia, and elevated levels of homocysteine Folate deficiency can cause
diarrhea, anemia, loss of appetite, weight loss, sore tongue
ABSORPTION:Folic acid also assists in digestion, and the nervous
system, and works at improving mental as well as emotional health. This nutrient may be effective in treating depression and anxiety.
Vitamin B12 (Cobalamin,cyanocobalamin,anti-pernicious anemia factor)
* FUNCTIONS: also keeps your central nervous system
healthy works with folic acid to produce healthy
red blood cells SOURCES:
Meat Milk products Eggs Cheese Chicken Fish
TOXICITY:- Vitamin B12 has a very low potential for
toxicity. DEFICIENCY:
Pernicious anemia- Vitamin B12 deficiency impairs the body’s
ability to make blood, accelerates blood cell destruction, and damages the nervous system.
- B12 deficiency can cause a type of anemia marked by fewer but larger red blood cells that's called pernicious anemia
ABSORPTION:- The absorption of dietary vitamin B12
occurs in the small intestine.
Vitamin C (Ascorbic Acid, anti-scorbutic factor)
FUNCTIONS: helps to heal wounds prevent cell damage, promote healthy gums and teeth, strengthen the immune system. It also helps the body absorb iron
SOURCES: Citrus juices and fruits Tomatoes Berries Potatoes with skins Green and red peppers Broccoli Spinach
TOXICITY: High intake of vitamin C (more than 1500 mg) may
decrease the absorption of copper in the intestine. Excessive doses of vitamin C can cause
diarrhea,nausea,abdominal cramps,headache,fatigue,insomnia,hot flashes,rashes in the skin,aggravation of gout symptoms,excessive urination,kidney stones,interference with medical tests
DEFICIENCY:Scurvy
ABSORPTION:Vitamin C, travel through the bloodstream.
