Sensitive vitamin ...

Nevertheless, natural folic acid is absorbed in a better way. If you take folic acid as a food supplement, you should always take it when eating. The absorbtion of folic acid is assited by other B-vitamins, especially vitamin B12. The folic acid level in the blood is lowered under continous consume of alcohol, birth control pill and aspirin.
Happiness hormones ...
Folic acid is involved in the production of the happiness hormones serotonin, noradrenalin and dopamine. The vitamins B1, B6, B12 and folic acid work together very closely there. When suffering from a folic acid deficiency, depressions may occur frequently. Thus folic acid is used in psychical diseases and neurologic disturbances successfully.
The pregnancy vitamin ...

This may be avoided by an early enough taking of folic acid (400 mcg), ideally already 2 months before pregnancy. So think of folic acid when having the wish to have children!
