Nutrients - Nutrients, whether they arrive in your body via food or liquids, as amino acids, vitamins or minerals are crucial to your good health.

Supplementary amino acids - Amino acids have marvellous healing properties and several are available in the form of supplements, in the same way as vitamins and minerals. Prescribing amino acids for therapeutic use is still relatively new and more research needs to be done, but their importance cannot be overemphasized. Our cells are able to manufacture more than 100,000 different proteins out of varying chains of amino acids with a very wide range of functions, from the creation of structural parts of the body to assistance with the production of hormones: The following are the most commonly prescribed for particular conditions. It is better to take supplements in their pure form, denoted by the prefix 'D' indicates synthetic production. Rather than consuming with meals, swallow them on an empty stomach with water for the best effect. Never take as a substitute for food.
A general amino acid complex supplement may well be helpful when digestion is impaired through illness or old age. Vegans and vegetarians who may be low on some dietary proteins could also benefit.
Caution Never take an amino acid supplement for more than a few weeks without professional advice as this may cause an imbalance with other amino acids. They are not recommended for pregnant women.

L-Arginine - A semi-essential amino acid that stimulates the secretion of the growth hormone, so it is very important for children. It also helps to put on muscle and is therefore often included in body-building programmes
Dosage Up to 4g daily.

Vitamins - basic facts - Vitamins are chemical compounds that are essential to human life. We simply cannot live without them, even though some are needed in very small amounts. Since we can only manufacture 3 of the 13 known vitamins in our own bodies in sufficient quantities to meet our needs, all the others must be supplied from food. Each has a particular role to play in regulating important chemical reactions through which the body is able to convert food into energy and living tissues. They also work in cooperation with each other, so that a deficiency in one can impair the function of another.

Vitamins are generally divided into two groups by scientists: the fat-soluble ones (A, D, E and K) and the water-soluble ones (B-complex and C). They can be extracted from their natural sources and made into pills or powders for use as supplements, but these in no way replace food; indeed they generally need to be taken with food. Nor are they drugs.

To encourage people to continue buying their supplements, some manufacturers turn them into chewable goodies. It's shocking to see that certain capsules contained the artificial sweeteners aspartame and saccharin as well as hydrogenated vegetable oil, all of which have been linked with health problems. Avoid these sort of confections and purchase supplements that contain just the nutrients you need together with any necessary filler or binder or natural protective coating; these might include calcium phosphate, calcium or magnesium stearate, cellulose, gum arabic, silica or zero, all of which are acceptable. Tablets and capsules should be sugar-free and devoid of any artificial flavourings or preservatives. If you're allergic to gluten, milk (lactose) or yeast, check that these substances are not included.

'Food state' supplements are more readily assimilated by the body, so that lower dosages can be taken. The full chemical names for all the nutrients should be included on the label, together with the actual amount contained in the pill. Some vitamins imported from America are measured in international units (IU) in terms of their biological activity as follows: 1 microgram (mcg) of vitamin A = 3.3IU, 1mcg of vitamin D = 40IU and 67mg of vitamin E (as d-alpha tocopherol) = 100IU.

Essential vitamins required every day in order to maintain health are listed below alphabetically, together with important points about each. The recommended daily allowance (RDA) given is the amount of each vitamin regarded as basic for good health in the average adult. This needs to be adjusted according to body weight, so that children will generally need less except when stated, while pregnant women may need more (their special needs are detailed in the page for womens health on one of the links below. Since the amounts differ slightly between countries, the highest has been selected. 'Mega-doses' are more than ten times this figure. While the RDA is helpful as a general guide, people vary greatly as to their requirements, depending on their genetic make-up as well as their lifestyle. For example, people under stress will use up far more vitamin C than the RDA, as will those who smoke. Some experts regard the RDAs as inadequate and currently Suggested Optimal Nutrient Allowances (SONAs) are being introduced; figures for these are given below if available.
Fatty meats have not generally been included under 'Sample food sources' if there are others, equally nutritious.

Vitamin A - Found only in animal sources, e.g. egg yolk, milk and liver. Its chemical name is retinol. However, vegans need not worry as several plants contain carotenes, such as carrots and some green vegetables, which the body then converts into vitamin A. In fact water-soluble beta carotene is the best way of taking it, as high doses of retinol in the oily form are stored in the liver and can be toxic if taken in excess.
Vitamin A is essential for the health of the eyes; it actually forms the visual purple, a pigment in the retina, which helps you to see in dim light. So the old saying that carrots help you see in the dark really is true! The vitamin is also vital for the growth of bones and teeth and for the health of the skin, helping to produce mucous secretions that protect against infections. Recent research indicates that carotenoids protect against cancer.
RDA 2,650IU/800mcg (EU and USA). SONA 6,600IU. Safe dosage of beta-carotene up to 50,000W, of retinol up to 5,000IU.
Caution Vitamin A in the oily form as retinol is toxic in high doses and is therefore not recommended as a supplement for lengthy periods.
Healing qualities Can be applied externally to treat skin disorders, such as acne, boils and ulcers. Helps remove age spots. Assists weak eyesight. Aids in the treatment of emphysema and hyperthyroidism. Protective against cancer.
Sample food sources (in mcg per 100g). As retinol: halibut-liver oil (40,000), cod-liver oil (18,000), organic liver (9,300-18,100), fortified margarine (900), butter (750), free-range egg yolk (400), Cheddar cheese (310), salmon (90), mackerel and herring (45). As carotene: carrots (12,000), dandelion leaves (8,400), parsley (5,100), spring greens (4,000), sweet potatoes (4,000), dried nori seaweed (3,888), spinach (3,600), watercress (3,000), mangoes (2,334), cantaloup melon (2,000), apricots (1,500), pistachio nuts (1,374), pumpkin (648), tomatoes (600).
Note To obtain retinol equivalents, divide carotene figures by 6.
Enemies High temperatures, especially frying, but survives ordinary cooking; and oxygen (but protected from oxidation by vitamin E); also light. Drying and canning reduce carotene levels in vegetables and fruit.

Vitamin B complex - Was first thought to be a single vitamin, but eight are now identified as being essential for humans, with some others required by animals only. They cannot be stored in the body and need to be replaced daily. They work in cooperation with each other, so that an excess of one can cause a deficiency in another. Any single supplement needs to be balanced with the complete complex; therefore, and B1, B2 and B6 should be supplied in equal amounts.

Vitamin B1 or thiamin - It is necessary for growth, good appetite and healthy nervous and digestive systems. The body requires it to release energy from carbohydrates. Its removal from foods due to refining causes the fatal disease beriberi; the vitamin now has to be put back into white bread by law.
RDA 1.5 mg (USA). SONA 7.1mg. Safe dosage up to 100mg. No known toxicity.
Healing qualities Cures beriberi. Beneficial when anxious or stressed. Important for the muscles and nervous system. Can be used in the treatment of herpes zoster.

Enemies This vitamin is unstable and destroyed by baking soda when heated, hence the advisability of making cakes without a raising agent. Also destroyed by sulphite preservatives. About 25 per cent is lost in cooking, generally with up to 40 per cent of the vitamin lost from boiling vegetables, so use that water up in soups and sauces. Some loss through food processing and storage.

Vitamin B2 or riboflavin - This vitamin is important for growth and for healthy skin and eyes. It helps the body
use oxygen efficiently when converting food into energy. RDA 1.7 mg (USA); slightly more for adolescent males and lactating women. SONA 2mg. Safe dosage up to 100mg. No known toxicity. Note that urine may turn yellow with extended high doses, but this is harmless.
Healing qualities Alleviates sore or cracked mouth, swollen lips or tongue and scaly skin around the ears and nose. Eye fatigue can be helped especially if sensitive to light. Generally good for the skin, nails and hair.
Sample food sources (in mg per 100g) Marmite (11.0), brewer's yeast (4.25), lamb's liver (4.40), lamb's kidney (2.30), spirulina seaweed (3.70), nori/laver seaweed (1.34), dried parsley (1.23), almonds (0.92), cream cheese (0.73), wheatgerm (0.72), goat's milk (0.63), wild rice (0.63), free-range eggs (0.47).
Enemies Destroyed by light, therefore do not leave your milk on the doorstep unless it is put in a dark container. Leaches into cooking water, so save that vegetable stock. Like B1, destroyed by baking soda.

Vitamin B3 or niacin - also nicotinic acid, niacinamide and nicotinamide. Especially important for normal brain function and the health of the nervous system, for conversion of carbohydrates into energy and also for the synthesis of the sex hormones, as well as insulin, cortisone and thyroxine. The body can make its own niacin with the assistance of the amino acid tryptophan, but only if vitamins B1, B2 and B6 are present.
RDA 19mg (USA); 20mg adolescent males and lactating women. SONA 25mg. Safe dosage up to 1,000mg as nicotinamide or 100mg as nicotinic acid. Toxic at three times these amounts. Tingling and flushing may occur, but these are not harmful.
Caution Diabetics and people with peptic ulcers or damaged liver, or with glaucoma are advised not to take megadoses of niacin.
Healing qualities Cures pellagra. Promotes healthy digestive system and can alleviate gastrointestinal problems and sometimes bad breath. Can ease migraine headaches. Increases circulation and reduces high blood pressure and cholesterol. Cuts down vertigo in Meniêre's syndrome. Can help to reverse negative personality changes. Good for the skin.
Sample food sources (in mg per 100g) Brewer's yeast (37.50), rice bran (29.80), lamb's liver (15.2), tuna fish (15.0), spirulina seaweed (12.8), turkey (10.0), halibut (9.0), mackerel (8.7), red salmon (5.5), raw mushrooms (4.0), cooked broad beans (3.0), raw peas (2.5).
Enemies Lost in cooking water unless reused, and food processing, but stable to heat. Sulpha drugs, sleeping pills, the contraceptive pill and alcohol all have a negative effect.

Vitamin B5 - Better known by its chemical name, pantothenic acid. Also referred to as panthenol or calcium pantothenate. Involved in carbohydrate and fat metabolism and helps to create antibodies. Essential for the correct functioning of adrenal glands. Important for growth, cell building and a healthy nervous system. This is one of the few vitamins that can be made in the body through the action of intestinal bacteria.
RDA 6mg (EU). Safe dosage up to 1,000mg. No known toxicity.
Healing qualities Fights, infections and aids healing of wounds. Helps reduce side-effects of antibiotics. Can
alleviate arthritic pain. An antidote to stress. If combined with vitamin C can cure some allergies.

Enemies Up to 40 per cent lost above boiling point. Leaches into cooking water. Destroyed by freezing* Harmed in food processing and canning. Caffeine, sulpha drugs, sleeping pills, the contraceptive pill and alcohol all have detrimental effects.

Vitamin B6 or pyridoxine. Closely concerned with the metabolism of protein, so you will need extra if you are a heavy meat eater (but let's hope you are not!). Needed to produce effective antibodies and red blood cells. Works in cooperation with zinc.
RDA 2mg (USA and EU). SONA 10mg. Safe dosage up to 100mg. May be toxic at 500mg.

Enemies Up to 50 per cent lost in juices through boiling, roasting or stewing unless reclaimed. Also lost through food processing, canning and long storage. Alcohol and the contraceptive pill have adverse effects.

Vitamin B12 or cobalamin - This vitamin is needed to make red blood cells and the fatty myelin sheath around nerves. Together with folic acid, it takes part in the synthesis of DNA (deoxy-ribo-nucleic acid) which governs the activities of each cell. Vegans can be deficient in this vitamin since its main sources are animal products, although it is present in yeast extracts; B-complex supplementation which includes this vitamin may therefore be advisable, otherwise there is a danger of pernicious anaemia and damage to the nervous system. Only very small amounts are needed and it is stored in the liver. Calcium aids absorption.
RDA 2mcg (UK and USA). 2.2mcg during pregnancy and 2.6mcg during lactation (USA). SONA 2 mcg. Extra needed if very large doses of vitamin C are being consumed. Safe dosage up to 1,000mcg. No known toxicity.
Healing qualities Along with folic acid prevents megaloblastic anaemia and is used to treat pernicious anaemia. Keeps the nervous system healthy. Good for the memory and sense of balance. Combined with folic-acid promotes vitality and a feeling of well-being, thus relieving bad temper. Important for growth and appetite in children.  Together with other B vitamins can ease menstrual flow.
Sample food sources (in mcg per 100g) Iamb's liver (81.00), lamb's kidney (79.00), mackerel (12.00), yeast extract (8.8), soya cheese (2.50), free-range eggs (2.40), lean beef (2.00), Mozzarella cheese (2.10), skimmed milk (0.40), tempeh (0.84), miso (0.21).
Enemies Stable to heat, but destroyed by acids and alkalis. Damaged by sunlight, the contraceptive pill, sleeping pills and alcohol.

Biotin - Occasionally referred to as vitamin H or coenzyme R, biotin is really a member of the B complex. It helps the body to change fats into fatty acids, which in turn aids energy production. Important for growth and for the maintenance of the nervous system, also for keeping the hair, skin, reproductive organs and bone marrow healthy. Another vitamin that is made in the intestines.
RDA 150mcg (EU). Safe dosage up to 3,000mcg. No known toxicity.
Healing qualities Slows down greying of the hair. Can prevent and heal eczema and dermatitis.
Sample food sources (in mcg per 100g) Free-range chicken liver (170.00), brewer's yeast (80.00), free-range egg yolk (50.00), wheatgerm (25.00), oatmeal (20.00), herring (10.00), mackerel (8.00), Camembert cheese (7.60), avocado (3.20), blackcurrants (2.40), raw leek (1.40).
Enemies Raw egg white prevents its absorption. Antibiotics and sulpha drug& the contraceptive pill, alcohol and food processing are biotin destroyers Up to 30 per cent is lost in cooking through discarded juices, unless reclaimed.

Folic acid or folacin - Another member of the vitamin B complex, although without its own number. Required to make certain components of DNA and RNA, it's therefore involved in passing on hereditary characteristics. Needed to make red blood cells and significant for growth and healthy nervous and digestive systems. It's stored in the liver until required.
RDA 300mcg (UK); 400mcg for pregnant women (USA). SONA 800mcg. Safe dosage up to 3,000mcg. May be toxic at 15,000mcg.
Caution Megadoses may not be suitable for people who suffer from convulsions or cancer with a hormonal basis. Healing qualities Prevents spina bifida and megaloblastic anaemia. Improves lactation. Protects against food
poisoning. Good for the skin and an antidote to stress.
Sample food sources (in mcg per 100g) Organic chicken liver (500), soya flour (345), wheatgerm (331), raw endive (330), dark-green leafy vegetables (90-140), dry butter beans (110), peanuts (110), Camembert cheese (102), almonds (96), cucumber (96), free-range eggs (51), kidney beans (50), beetroot (50).
Enemies Serious losses result from food processing, canning, leaching into cooking water, reheating, sunlight and long term storage. Sulpha drugs and the contraceptive pill have damaging effects.

Vitamin C or ascorbic acid - Many animals make their own, but humans cannot, so frequent intake in the diet is vital. It is best absorbed in conjunction with bioftavonoids. It plays a part in the creation of collagen, a protein that holds tissues together and so is essential for the health of bones, cartilage, blood vessels, teeth and gums. Also needed for the synthesis of certain hormones and the effective absorption of iron from vegetables. Supplements should be taken in divided doses.
RDA 60mg (EU and USA). SONA 400mg. Safe dosage up to 5,000mg daily.
Caution Do not suddenly cease megadoses as 'rebound scurvy' can occur; gradually reduce amounts, Very high doses at around 20,000mg for extended periods may create kidney stones.
Healing qualities Prevents scurvy. Aids healing of wounds and bleeding gums. Boosts the immune system and prevents infections. Controls cholesterol levels. Promotes longevity. Protective against cancer.
Sample food sources (in mg per 100g) Acerola cherries (1,000-2,330), rosehips (1,250), blackcurrants (200), parsley (150), raw broccoli (110), raw green peppers (100), kiwi fruits (98), raw Brussels sprouts (90), lemons (80), oranges (71), strawberries (60), watercress (60), raw red cabbage (55).
Enemies Very unstable to all cooking, food processing and canning, particularly if copper, iron or nickel are employed. At least 60 per cent destroyed by heat, oxygen, baking soda and through leaching. Therefore, eat vegetables raw in salads. Smokers beware: each cigarette kills off 25mg of vitamin C. City dwellers also need extra as carbon monoxide impairs this vitamin.

Vitamin D - Calciferol or ergocaldferol (vitamin D2) is produced in plants when exposed to UV light, while cholecalciferol (D3) is formed in the skin of humans and animals in the same manner, hence the term 'sunshine vitamin'. The right amount is essential for healthy bones as it stimulates calcium and phosphorus absorption.
RDA 5mcg/200IU (EU and USA); more for dark-skinned people in northern latitudes and double for housebound adults and children. Safe dosage up to 1,0001U. Toxic at 2,0001U.
Caution Stored in the liver, therefore toxic with prolonged intake. Best obtained naturally rather than through supplementation.
Healing qualities Helps prevents rickets, osteoporosis, osteomalacia and severe tooth decay.
Sample food sources (in mcg per 100g) Cod-liver oil (210,00), herring (22.50), mackerel (17.50), salmon (12.50), tuna 45.80), free-range egg yolk (5.00), dried skimmed milk (2:10).
Enemies Smog. Destroyed in foods by light, oxygen and acids.

Vitamin E - Prevents polyunsaturated fatty acids in membranes and other body structures from harmful oxidation
(i.e. combining with oxygen). Neutralizes the effect of free radicals (cancer-causing agents). Keeps the red blood cells healthy and prolongs their life. Selenium increases its potency. Best taken as d-alpha tocopherol with oily foods.
RDA 10mg/15IU (EU and USA); SONA 400IU. More for pregnant or lactating women or those going through the menopause. Safe dosage up to 8001U. May be toxic at 1,5001U.
Caution High-dose supplements are not advised for patients with rheumatic heart condition. Diabetics or those with an overactive thyroid or high blood pressure should build up amounts gradually and should not exceed 400mg daily.
Healing qualities A natural anticoagulant. Can be applied externally to reduce scar formation. Contributes to youthfulness of tissues. Alleviates fatigue through efficient use of oxygen. Increases fertility and helps prevent miscarriages.
Sample food sources (in mg d-alpha tocopherol per 100g) Wheatgerm oil (133.00), wheatgerm (22.00), hazelnuts cold-pressed sunflower-seed oil 49.00), maize oil (11.00), soya-bean oil (10.00), olive oil (5.00), margarine (8.00-25.00), peanut butter (4.70), grapes (4.00), blackberries (3.50), avocado (3.20), free-range egg yolk (3.11), butter (2.00), spinach (2.00), parsley (1.80).
Enemies Freezing, so do not freeze bread. Food processing, commercial cooking and deep frying. Chlorine in drinking water. Ferrous sulphate, inorganic iron, employed in some vitamin pills destroys vitamin E (check the labels and choose an organic iron, e.g. ferrous citrate).

Vitamin K - K1 (phylloquinone, phytylmenaquinone or phytonadione) is obtained from foods, while K2 is formed in the intestines through the action of bacteria. K, (menadione or menaphthone) is a synthetic. This vitamin is concerned with the proper clotting of the blood.
RDA 70-140mcg (USA estimated). Safe dosage up to 600mcg.
Toxic at 1,000mcg.
Healing qualities Can prevent coeliac disease and colitis. Protects against internal bleeding and haemorrhages. Helps control menstrual flow. Aids in the healing of nose bleeds.
Sample food sources Available in fresh leafy green vegetables, especially broccoli, spinach, cabbage and lettuce, also alfalfa and kelp. Yoghurt is another source.
Enemies Antibiotics prevent its formation in the intestines. Decomposed by baking soda and other alkalis, also aspirin. Radiation, freezing and food processing destroy it, as does light.

Minerals and trace elements - Like vitamins, these have particular physiological functions and are therefore vital to health. Those that are required in significant amounts are: calcitun, chloride, magnesium, phosphorus, potassium and sodium; others are used in only tiny amounts of less than 100mg and are often referred to as trace elements. These include chromium, cobalt (as Vitamin B12), copper, iodine, iron, manganese, molybdenum, selenium and zinc.
Much has still to be discovered about the precise biochemical activities of minerals. Apart from sodium, potassium and chloride, which are easily absorbed by the body, most minerals can only be utilized with the assistance of carrier proteins. When you buy them in the form of supplements, therefore, check that the word 'chelated' appears on the label. This means that the mineral is attached to something that aids absorption, such as an amino acid. Gluconates, aspartates and citrates work in a similar way. Be especially careful when buying minerals in the form of compounds. For example, a 100mg tablet of zinc orotate may contain only 15mg of elemental zinc, and it is this lower figure which you need to know.

Calcium - Humans contain a large amount of this mineral in their bodies, more than any other mineral, some 2 to 31b (1 to 1.4kg), most of it in the bones and teeth. It is constantly being lost and replaced, at the rate of about 700mg a day. It is obvious, therefore, that good dietary sources are vital. The small amount in the soft tissues and fluids helps to regulate nerves, muscles and hormones, and the clotting of blood. Best absorption is achieved if there is twice as much calcium as magnesium, and when vitamin D is available. Take chelated or as dolomite, with protein food.
RDA 800mg, inducting children 1-10yrs; 1,200mg 11-24yrs
(EU and USA); 1,200mg during pregnancy and lactation and

Enemies Depleted soil. (The cabbage family contains substances that are goitrogenic in animals, excessive raw cabbage may inhibit iodine absorption.)

Iron - More than half the body's iron helps to constitute the haemoglobin of red blood cells, and a much smaller amount the myoglobin in muscles, both transporters of oxygen to the body's tissues. Some is involved in the creation of enzymes that assist in the release of energy from food. About one-quarter is stored as ferritin for future use. Red blood cells live for only about 120 days, after which they are remade using ferritin from the bone marrow. Iron is necessary for the proper assimilation of B vitamins Women can often be iron deficient due to menstrual loss. Take the ferrous forms of supplements, with food.
RDA 12mg, 15mg for menstruating and lactating women; 30mg during pregnancy (USA). Safe dosage up to 60mg. Toxic at 100mg.

Sodium - Essential as this mineral is, people in the West are dying from too much of it. It is a major cause of high blood pressure and heart disease. There is no need to have salt on the table or to add it to cooking, as sodium is widely available in many natural foods. There is also far too much of it in processed fare, especially meats and condiments, which should be avoided.
Of the approximate 90g of sodium found in the human body, most is divided between the bones and the body fluids. It regulates the fluid balance, preventing excessive loss, and it also governs various functions of the nerves and muscles.
RDA 500mg estimated (USA). Supplements are not recommended since intake is already too high, causing serious potassium loss.

Water - Those of us who live in countries where water is plentiful often take it for granted. The turn of a tap brings it gushing forth and we can put the kettle on and make as many cups of tea as we like. In fact we have to remind ourselves that we cannot live without it.
In hot countries dehydration, often through excessive loss of water in diarrhoea, especially among children, causes countless deaths. Most of our cells contain about 75 per cent water and they will quickly die if this level falls. Indeed water plays an important part in a host of their chemical reactions. Being a good solvent many nutrients can be carried about the body in the watery fluid of the blood. Waste substances can also be excreted in water via the kidneys.
As we all know, water regulates our temperature by cooling our bodies in the form of perspiration. We also lose it when we breathe out and of course when we urinate. We must therefore replenish this loss in our diet. Make sure you drink plenty (ideally at least 3 pints/1.5 litres daily and preferably filtered) so that your body can function efficiently.
