| Vitamins |
Effects |
Deficiency Symptoms |
|---|---|---|
| Vitamin A / beta-carotene |
Important for vision, the skin, mucous membranes and growth |
Night blindness; xerophtalmia; keratomalacia; inhibited growth; increased susceptibility to infection |
| Vitamin D |
Necessary for calcium and phosphate metabolism and bone formation |
Rickets; osteomalacia; osteoporosis |
| Vitamin E |
Controls muscle and gland functions; stimulates blood circulation; antioxidant effect in metabolism |
Fatigue; disturbed circulation, growth and development; increased lipofuscin production |
| Vitamin K |
Important for the blood coagulation system; regulates redox reactions |
Tendency to bleed |
| Vitamin B1 |
Important for carbohydrate metabolism and the nervous system |
Beriberi; nervous cardiovascular disorders; irritability; muscular weakness |
| Vitamin B2 |
As a component of enzymes it is involved in all metabolism for energy generation; controls oxidation-reduction mechanisms in the respiratory chain |
Disturbed growth and vision; cloudiness of the eye lenses; oversensitivity to light; rhagade formation; skin changes; cardiovascular disorders |
| Vitamin B6 |
Important for protein metabolism, the biosynthesis of amines and formation of blood cells; biochemical links with other B vitamins |
Dermatoses; seborrhoic changes; hypochromic anaemia; neuropathies |
| Vitamin B12 |
Stimulates the formation of blood cells; important for the synthesis of protein and nucleic acid |
Pernicious anaemia; nervous disorders |
| Folate |
Controls reproduction and cell division in intermediate metabolism; central function in protein metabolism |
Megaloblastic anaemia; neurological disorders; changes in the intestinal mucosa |
| Niacin |
Central role in glycolysis and lipid synthesis; important for energy generation |
Alpine scurvy (pellagra); hyperkeratosis; gastrointestinal disorders; disorders of the central nervous system |
| Pantothenic acid |
Component of enzyme systems in the generation of energy from nutrients |
Deficiency symptoms are rare; unspecific general symptoms such as headache, fatigue, weakness |
| Biotin |
Essential effects in metabolism; important for the skin and hair |
Deficiency symptoms are rare, since it is produced by the body’s own intestinal flora; dermatitis, anorexia, depression |
| Vitamin C |
Being a redox system, vitamin C mobilizes the body’s own defence mechanisms, boosts physical performance and is involved in the synthesis of important building materials such as collagen (for the teeth, bones, cartilage, skin), carnitine (factor in energy generation), detoxification of foreign substances (nitroso compounds); regulates the transportation and storage of iron |
Scurvy; bleeding from the mucous membranes and skin; lowered resistance to infection and impaired physical performance; increased tiredness, fatigue |
| Minerals |
Efffects |
Deficiency Symptoms |
|---|---|---|
| Calcium |
Important for bones and teeth, nerve and muscle cells, blood coagulation, muscle contraction, cardiac functions and hormone release |
Osteoporosis; rickets; muscular weakness |
| Chromium |
Carbohydrate metabolism; breakdown of fatty acids; important for glucose tolerance, especially in old age and persons with diabetes |
Weight loss; reduced glucose tolerance; risk of diabetes |
| Iron |
Blood formation; oxygen supply in the blood; formation of the blood pigment haemoglobin; constituent of numerous enzymes; contributes to the storage and transportation of oxygen |
Inhibited growth; muscular weakness; pallor; anaemia; fatigue; impaired growth of skin, nails and hair Impaired mental development |
| Fluorine |
Ensures the stability of bones and teeth; promotes wound healing and vision; inhibits caries bacteria |
Damage to teeth: tooth decay |
| Iodine |
Supports the function of the thyroid gland; regulates metabolism and body temperature |
Hypothyroidism; goitre formation; weight fluctuations |
| Potassium |
Regulates the water balance of the cells, cardiac rhythm, protein synthesis, conversion of carbohydrates. Important for protein and glycogen formation and release of hormones |
Muscular weakness; disturbed cardiac function; stomach problems; diarrhoea; enteroparesis; irregular pulse |
| Copper |
Essential for metabolism, transportation of iron and functioning of the immune system. Constituent of enzymes in the muscles, liver and bones |
Anaemia; insomnia; elevated cholesterol levels; weakness; lack of appetite; shortness of breath |
| Magnesium |
Important for physical energy, muscles and bones. Prevents cramp, activates enzymes, lowers the cholesterol level. Important for the storage and release of hormones |
Cramp; irritability; poor concentration; cardiac arrhythmias; gastro-intestinal problems |
| Manganese |
Component of numerous enzymes, especially for carbohydrate and fat metabolism, metabolic processes, production of sexual hormones |
Impaired skeletal growth and fertility |
| Molybdenum |
Assists the metabolism of carbohydrates, fats and iron |
Reduced uric acid concentration; excessive uptake of copper |
| Sodium |
Necessary for the absorption and transportation of nutrients. Regulates the water balance and blood pressure |
Cramp; circulatory problems |
| Phosphorus |
Constituent of bone. Important for genetic information, energy metabolism and the acid-base balance |
Muscular weakness; bone disorders |
| Selenium |
Binds free radicals; promotes tissue elasticity; important constituent of bone and tooth mass |
Damage to cardiac muscle; bowel disease |
| Zinc |
Strengthens the immune system and the eyes. Important for the skin and connective tissue and the storage of insulin |
Lack of appetite; hair loss; skin lesions |
