The Need for NutrientsWe are not all alike. The needs for your particular lifestyle must be adequately covered, preferably through eating more of the appropriate kinds of foods. In cases where nutritional deficiencies are causing health problems, the use of nutritional supplements may also be helpful. For example, if you smoke and drink alcohol frequently your nutritional needs will be higher. If you are pregnant, if you live in a polluted environment, if you have a high stress occupation or are suffering emotional stress, if you suffer from allergies, if you have any sort of disease, degenerative illness or inherited weakness - all of these factors may increase your needs. The poor nutritional quality of many purchased foods is another factor. Depleted soils and lengthy storage, as well as toxicity from pesticides, antibiotics, additives, and so on can make an apparently healthy food of little value. Tests have shown that, for example, most people do not obtain adequate zinc, folic acid or the essential fatty acids in their diet, and health (physical and mental) suffers - the weakest link of the inter-acting bodily systems inevitably gives way. Deficiency of any of the essential nutrients (below the RDA amount) will, over a period of time, result in illness. Recent research has shown that most of the population in Western countries is deficient in at least a few nutrients (the most common being zinc, selenium, B and C vitamins) and literally on the edge of illness. Moreover, individual nutritional needs are frequently higher than the RDA amounts, and to reverse the effects of decades of poor diet and the resulting toxicity, yet alone to attain optimum health, larger amounts are required - preferably as part of an improved diet but if necessary, through supplements as well. An Optimum Nutrition FormulaVitamins and minerals are essential for almost every function of the body. They are vital for energy and they protect you from premature ageing and degenerative diseases. And because they work together they are best digested and absorbed as natural and wholesome foods, in the context of a balanced and varied diet, not just in isolation in the form of nutritional supplements. Nevertheless, supplements can play a role to prevent the risk of deficiencies occurring and to remedy health symptoms caused by long-standing deficiencies due to inadequacies in our diet - all too common with cultural bad eating habits and over-processed foods. If you are suffering from significant health problems, it is also necessary to obtain personal professional guidance for remedial therapy from a nutritional consultant, who will work in liason with your doctor. The question is, how much do you need of the various vitamins and minerals? There's a big difference between the amount required to prevent deficiencies that would lead to serious degeneration, and the amount of each vitamin and mineral you need for optimum health. A few years ago, scientists at the University of Alabama worked this out for every nutrient and called the amounts Suggested Optimal Nutrient Allowances or SONAs. The following formula is based on SONAs and gives the amount of each essential vitamin and mineral that you need contained in your diet for optimal health. The formula provides: Vitamin A 7500 i.u. - Retinol,
a fat-soluble vitamin and antioxidant, derived from animal sources
such as dairy foods, fish liver oil, eggs and liver. Like other
fat-soluble vitamins, this form of vitamin A can build up in
the body tissues causing undesirable side effects if taken in
excessive amounts (much more than 7500 i.u. per day). Excess
should particularly be avoided by pregnant mothers or those
expecting to become pregnant. A good supply of vitamin A is
however essential for optimal functioning of the eyes, gums,
skin, the mucous lining of the nasal sinuses, respiratory and
digestive tracts. Also for bone development, production of sex
hormones and normal immunity. Vitamin D 300 i.u. - Ergocalciferol,
a fat-soluble vitamin derived from animal sources (fish, dairy,
eggs). Needed for the absorption, utilisation and retention
of calcium, normal sexual function, and calcification of bone
to maintain strong bones and teeth. Helps prevent loss of calcium
from urine. Made by the body when exposed to sunlight. Toxic
in excess (more than 1500 i.u. daily) as this may cause calcification
of the liver. Vitamin E 150 i.u. - D-alpha
tocopherol is a fat-soluble antioxidant found in nuts, seeds
and vegetable oils which it helps to prevent becoming rancid,
just as it protects fats within the body from oxidation. ts
antioxidant properties help limit the damage to all body cells
caused by naturally present free oxygen radicals, and therefore
helps prevent cancer and ageing. Needed for maintenance of a
healthy heart and circulation, normal sexual function, proper
growth and repair of skin. Helps heal scar tissue, oxygenate
muscles and maintain immunity. Vitamin K (not included) - Phylloquinone, fat-soluble, required for blood clotting, is found in many vegetables, dairy products and wholegrain cereals. It is also produced by healthy intestinal bacteria, so it is rarely deficient except in young infants (nursing mothers should eat cauliflower and cabbage). Vitamin C 300 mg - Ascorbic acid,
a water-soluble antioxidant found in fruits and vegetables.
Strengthens the immune system - fights infections. Makes collagen,
the inter-cellular glue, keeping bones, skin and joints firm
and strong and strengthening blood vessels. A powerful antioxidant,
helping to detoxify pollutants and protect against cancer and
heart disease. Helps make anti-stress hormones and needed for
metabolism. Helps the absorption of iron from food. Most animals
make the equivalent of several grams of vitamin C daily; however,
by a quirk of evolution, humans cannot produce their own, so
we really do need the benefit of further supplementation. Vitamin B1 37.5 mg - Thiamin,
a water-soluble vitamin, found in association with other B Complex
vitamins in wholemeal products, brown rice, many vegetables,
meat, nuts and dairy, is unstable and frequently destroyed by
cooking or by preservatives. B1 is needed for carbohydrate metabolism
and may be deficient in those on a high sugar diet. Helps maintain
appetite, normal functioning of the nervous system, eyes, hair,
heart and other muscles. Helps keep mucous membranes (digestive
lining, lungs, etc) healthy. It is needed for digestion, growth
and maintenance of muscle tone. Vitamin B2 37.5 mg - Riboflavin,
a water-soluble B Complex vitamin found in vegetables, fish
and dairy, works particularly closely with vitamins B6 and B3
and selenium. It assists in the metabolism of proteins, carbohydrates
and fats and therefore is needed for energy. It plays a role
in cataract prevention and is needed for healthy mucous membranes,
skin, nails, hair and the absorption of iron. It is also a necessary
factor in healthy functioning of the nervous system and helps
to regulate body acidity. Requirement is increased with alcohol
or drug abuse, consumption of coffee, the contraceptive pill,
antibiotics and pregnancy. Unrequired B2 harmlessly colours
the urine yellow. Vitamin B3 75 mg - Niacin or
nicotinic acid, a water-soluble B Complex vitamin found in vegetables,
fish, dairy and unrefined cereals, has a vasodilatory effect
(felt as flushing of the skin) which helps take nutrients to
cells and remove toxins and also reduce stickiness of the blood.
(Niacinamide, another form of the vitamin, does not have this
beneficial effect). B3 is essential for energy production, normal
digestion, nerve function and the skin. Helps balance blood
sugar and lower cholesterol and triglyceride levels. It is also
needed for the production of vital hormones such as cortisone,
oestrogen, progesterone and thyroxine. Deficiency can occur
with alcohol or drug abuse, or protein deficiency, and may,
in extreme cases, result in pellagra (dematitis, diarrhoea and
dementia). Vitamin B5 75 mg - Pantothenic
acid, a water-soluble B Complex vitamin found in eggs, lentils,
unrefined grains and vegetables. B5 is essential in energy production
and the synthesis of hormones and blood cells. Known as the
'Anti-Stress Vitamin' it is needed to make the neurotransmitter
acetylcholine and therefore for proper brain activity and nerve
transmission. It is also needed by the adrenal glands to make
glucocorticoids, the anti-stress hormones, and along with glucosamine
has been found helpful in arthritis and relieving joint pains
and stiffness. Helps healing and counteracts allergy effects.
Maintains normal hair pigment. Vitamin B6 75 mg - Pyrodoxine,
a water-soluble B Complex vitamin found in meat, fish, vegetables,
bananas, wholegrains, seeds and nuts, may be toxic in extreme
doses (above 1000 mg). Works with other B Complex vitamins,
zinc and magnesium. Required for the metabolism and synthesis
of proteins. Needed for making energy, utilizing essential fatty
acids, keeping levels of the female hormone oestrogen stable
(and therefore effective in preventing pre-menstrual tension).
Essential for efficient nerve transmission, protein digestion
and utilisation, making healthy red blood cells and antibodies.
Involved in the maintenance of the circulation, the skin, the
immune system and the production of chemicals in the brain which
govern mood, sleep patterns, etc. Helps absorption of B12 and
maintenance of fluid balance in the body. Vitamin B12 15 micrograms - Cyanocobalamin,
a water-soluble B Complex vitamin found in fish, eggs, meat
and dairy produce which often works together with folic acid
in the body. Needed for making energy. Essential for the production
of red blood cells and is also needed to make DNA. Helps make
the myelin sheath that insulates nerve cells. Vegans and vegetarians
are susceptible to deficiency and other causes are: alcohol,
coffee, smoking, lack of calcium or iron, diabetes and liver
disease. In extreme may cause pernicious anaemia. Folic Acid 150 micrograms - Folic
acid is water-soluble, part of the B Complex group of vitamins,
found in leafy green vegetables, citrus fruits, eggs, organ
meats, wholegrains, seeds and nuts but often destroyed by overcooking.
Required for protein synthesis, works with B12 in the formation
of red blood cells and is also vital for rapidly dividing cells
and the developing foetus. It is needed to make RNA and DNA
and therefore essential for the repair and manufacture of all
cells. Needed for proper growth, brain activity, normal nervous
function. Recent research indicates that folic acid may play
a protective role against heart disease due to its ability to
lower homocysteine levels; along with B6 and B12 it reduces
the risk of heart attacks. It also helps to regulate histamine
levels in the body. As with B12, anaemia will result when folic
acid is low. 400 micrograms is needed prior to and during pregnancy
to prevent spina bifida or other neural tube defects. It is
adversely affected in the body by alcohol, coffee, coeliac disease,
oral contraceptives, stress, the taking of drugs and smoking.
Biotin 75 micrograms - Biotin,
a water-soluble co-enzyme which works with the B Complex vitamins,
is found in many vegetables, nuts, seeds, fish, milk, eggs.
Biotin is part of many enzyme systems and is involved in the
conversion of amino acids to protein. It is involved in the
production of energy from carbohydrates, fatty acid metabolism
and the conversion of folic acid to a biologically active form.
It helps maintain healthy skin and hair, good muscular tone
and a balanced hormonal system. Promotes healthy sweat glands,
nerve tissue and bone marrow. Antibiotics, excessive intake
of alcohol, coffee or raw eggs will inhibit dietary intake.
Choline 30 mg - Choline is a
constituent of the emulsifier lecithin, found in egg yolks,
meat organs, green leafy vegetables, wheat germ, soy beans,
and can be made in the body so strictly speaking it is not a
vitamin. It helps make acetylcholine and is therefore essential
for brain function. Necessary to help break down accumulating
fats. Reduces lactic acid build-up in muscles. Inositol 30 mg - Like choline,
a constituent of lecithin, needed for hair growth, healthy arteries,
normal fat and cholesterol metabolism. MineralsMinerals are originally extracted from the soil by plants. Like vitamins, they may be obtained directly from plants or indirectly via meat. However they are frequently refined out of foods and over-farmed soils may be deficient in trace minerals. For this reason it is essential to eat organically grown, unprocessed produce.
Calcium deficiency symptoms: muscle cramps, tremors or spasms, insomnia or nervousness, joint pain, osteoarthritis, tooth decay, high blood pressure. Magnesium 225 mg (as citrate, aspartate, or other organic form) - Magnesium is present in green leafy vegetables, peas, nuts, brown rice, wholemeal products, seeds and some fruits (and therefore is more commonly deficient than calcium). It is involved as a co-factor in most enzyme reactions in the body and is necessary for the production of energy. It works together and in balance with calcium in maintaining bone density and in nerves and muscles. For bone integrity, calcium needs to be balanced with magnesium, preferably 2:1. Calcification of soft tissues can occur if there is a calcium/magnesium imbalance. The two minerals also act together in the regulation of blood pressure. A lack of magnesium is strongly associated with cardiovascular disease. Shortage of magnesium can also lead to loss of control over the relaxing and contriction of muscles, as again, calcium and magnesium act in balance. Magnesium may be lost through food processing and refining, and its absorption reduced with a high-fat diet, so it is widely deficient among those with a fast-food diet, and indeed, is deficient in most Western people! Magnesium has been shown to be beneficial for women with pre-menstrual cramps or sugar cravings, especially when taken in conjunction with vitamin B6. Deficiency may also arise with prolonged treatment with diuretics. It is a primary cause of most ADD cases (along with Zinc deficiency) and other types of learning disability and psychological disturbance. Magnesium deficiency symptoms: Muscle tremors or spasms, "restless leg syndrome", chronic weakness and exhaustion, insomnia or nervousness, high blood pressure, headaches, irregular or rapid heartbeat, constipation, excessive muscle tension, fits or convulsions, ADD and hyperactivity, difficulty with mental concentration and memory, nausea, apathy, depression, anorexia. Potassium (not supplied) - Potassium (found in fruits, vegetables and wholegrains) works in conjunction with sodium in maintaining water balance and proper nerve and muscle impulses. The more sodium is eaten the more potassium is required and so a relative deficiency of potassium is widespread, with the high amounts of salt in typical diets. Potassium deficiency symptoms: vomiting, abdominal bloating, muscular weakness, loss of appetite (more likely to occur in those taking diuretic drugs, laxatives or corticosteroids). This is not supplemented in this Formula because of the large amounts required which are best obtained from dietary sources. Magnesium-potassium-aspartate, however, is a particularly effective combination in its 'anti-fatigue' and cholesterol lowering effects. Iron 15 mg (as citrate or other organic form) - Iron (found in meat, eggs, nuts, beans, oatmeal) is needed as part of the haemoglobin molecule to carry oxygen around the bloodstream, and for the production of hydrochloric acid for protein digestion in the stomach. A deficiency of iron can result in anaemia. Those particularly at risk include pregnant women, children, women with heavy menstruation and people with malabsorption problems. Iron deficiency symptoms: pale skin, sore tongue, fatigue or listlessness, loss of appetite or nausea, heavy periods or blood loss. Zinc 15 mg (as citrate or other organic form) - Zinc (found in meat, shellfish, herrings, wheat germ, eggs, cheese, nuts, pumpkin and sunflower seeds) is needed for normal functions of taste and smell, for insulin formation, reproductive and immune systems, tissue renewal, and for healthy bones, skin and teeth. It is essential (along with B6) for protein synthesis including hormones, enzymes and antibodies. It is needed for over 90 enzymatic processes in the body. High levels are found in semen and a deficiency is linked to male infertility; zinc is also necessary for a healthy prostate gland. Hydrochloric acid, necessary for digestion of proteins and assimilation of minerals, is dependent on zinc and B6 for its secretion by the stomach. Zinc is vital for the growth and maintenance of the nervous system; therefore it is important in brain function and deficiency is linked to depression and anxiety, and it is an important factor in schizophrenia. Stress increases the need for zinc. With zinc deficiency there is increased risk of having a baby with low birth weight or premature. Women suffering from postnatal problems frequently benefit from supplementing zinc and B6. It is especially important to supplement because most zinc is lost in food processing or never exists in substantial amount because of nutrient-poor soil. Vegetarians and others on a high fibre diet may need more zinc to offset the additional phytate present, which binds to zinc and other minerals, making them less easily absorbed by the body. Zinc deficiency symptoms: poor sense of taste or smell, white spots on the fingernails, frequent infections, slow wound healing, stretch marks, acne, poor skin condition, low fertility, pale skin, irritability, ADD, tendency to depression and anxiety, poor digestion, loss of appetite, impotence, prostate enlargement, growth problems. Manganese 4.5 mg (as citrate or other organic form) - Manganese (found in tropical fruits nuts, seeds, wholegrains, green leafy vegetables, eggs) is associated with iron metabolism and utilisation of vitamin E and B vitamins. It has a critical role in the activation of over 20 enzymes involved in growth, digestion and assimilation of nutrients, the nervous system, healthy cartilage and bones, cell protection against viruses, and making energy. Manganese is found in female hormones and is required in the production of nucleic acids that are part of the genetic code. Forms part of the important antioxidant enzyme Superoxide Dismutase. Reduced fertility, birth defects and growth retardation may, in part, be a result of manganese deficiency. Manganese deficiency symptoms: muscle twitches, joint pain, childhood growing pains, dizziness or poor sense of balance, fits or convulsions, sore knees, fatigue, nervous irritability, and in some cases: schizophrenia, Parkinson's disease and epilepsy. Iodine 45 micrograms (as iodide) - Iodine (found in kelp, vegetables grown in iodine-rich soil, onions and all seafood) is needed for thyroid hormones which control metabolism. Iodine deficiency symptoms: slow mental reaction, weight gain, lack of energy. Copper 75 micrograms (as citrate or other organic form) - Copper (found in peas, beans, wholegrains, liver, seafood) is essential for the utilization of Vitamin C and is required to convert the body's iron into haemoglobin. Copper deficiency symptoms: anaemia, edema, rheumatoid arthritis. In excess, copper lowers zinc levels and produces hair loss, insomnia, irregular menstruation, depression and schizophrenia. The balance of zinc and copper in the diet should be 15:1. Chromium 30 micrograms (as picolinate) - Chromium (found in liver and seafood, wholegrains, mushrooms and asparagus) is part of the Glucose Tolerance Factor (with B3 and amino acids) necessary for the regulation of blood sugar levels. Chromium works with insulin for normal glucose metabolism and conversion of amino acids into protein. Continued stress or frequent sugar consumption depletes the body of chromium. A diet high in refined carbohydrates can also lead to deficiency as the food processing removes much of the natural chromium content. Other causes of depletion include infection, strenuous physical exercise and pregnancy. Deficiency is implicated in adult onset of diabetes. Impaired glucose utilisation can promote sugar conversion to fats and cholesterol leading to obesity and arteriosclerosis. Deficiency symptoms: excessive or cold sweats, dizziness or irritability after 6 hours without food (hypoglaecemia), need for frequent meals, cold hands, need for excessive sleep or drowsiness during the day, excessive thirst, addiction to sweet foods. Selenium 45 micrograms (as selenomethionine) - Selenium (found in seafoods, liver and kidney and in small amounts in other meats, grains and seeds) helps maintain a healthy heart, eyes, liver, skin and hair. Part of the important antioxidant enzyme Glutathione Peroxidase, giving the body protection against cancer, premature ageing and degenerative diseases. Needed for prostaglandin formation, involved in hormone balance. Potentiates the antioxidant function of Vitamin E. Helps produce CoQ10, required in cells to make energy. Selenium is particularly vulnerable to loss during food processing and the low amounts found in fruit and vegetables make this especially important for vegetarians to supplement. Considerable loss of selenium occurs in the seminal fluid. There have been indications of a connection between inadequate selenium and Downs Syndrome. Deficiency symptoms: family history of cancer, signs of premature ageing, cataracts, high blood pressure, frequent infections.
