Folic Acid is also known as vitamin B-9. It has various jobs in the body one includes getting the blood circulation to the scalp. This could especially be pertinent to balding as loss of circulation to the scalp can be a cause of hair loss. It is interesting to note the stress is thought to work on a similar principle of restricting the bloog supply to the scalp
As well as of course supplementation with a good multi vitamin, it is more than possible to get the appropriate amount of folic acid from a well rounded diet. High concentration sources of folic acid include, green vegetables which are leafy, as well as fruits. The level of folic acid needed by each individual varies depending on their genetic makeup and their lifestyle.
The recommended daily dosage of folic acid is 400 micrograms. This is equivalent to 4 cups of spinach, or can be had with a capsule of folic acid. It is best to take the supplement with a meal as otherwise the stomach may be irritated.
It is not likely that there will be any side effects, however the most common side effects of folic acid are diarrhea and drowsiness. Generally these effects should stop once supplementation stop. Consult your doctor if in doubt or if you have any other underlying conditions and are concerned.
