Folic Acid
Folic acid, a member of the vitamin B group of nutrients, is found in a wide variety of foods and is best known for its ability to prevent spina bifida in newborn babies. Unfortunately it's the first three months of pregnancy that are crucial in the development of the baby's spine and when having adequate folic acid is so important. Many women don't realise that they are pregnant until the second or third month. In spite of the wide availability of folic acid few people manage to get the 200 micrograms they need each day from their diet. Folic acid is also needed for the body's production of healthy red blood cells.
Latest research shows that it also plays a key role in the prevention of heart disease by controlling the amount of homocysteine in the blood. High levels of this naturally occurring chemical are known to be a factor which increases the risk of fatal heart attacks. Anaemia may be caused by getting too little folic acid and a supplement of 200 micrograms a day can soon help improve the condition and overcome the symptoms of severe tiredness.
After the menopause the blood levels of homocysteine tend to increase with a related increase in the risk of osteoporosis. For this reason it's extremely important for any women not having periods (for whatever reason) to make sure they eat a regular selection of folic acid rich foods. It's not advisable to take large amounts of folic acid - more than 500 micrograms daily - for long periods without discussing this with your GP, as at this level it may mask the symptoms of pernicious anaemia. Folic acid can also interfere with medicine taken for epilepsy, so epileptics must also talk to their doctor before taking it.
It's always best to take folic acid supplements together with food as this improves absorption. Alcohol, the pill, aspirin, anti-inflammatory drugs and medicines for non-insulin dependent diabetes can all interfere with the absorption of folic acid.
