Folic acid, iron and vitamin B6
Besides these two vitamins, iron is also an important factor. Anaemia is often caused by an iron deficiency, but can also be caused by a deficiency of vitamin B12, B6 and/or folic acid. That is why it is advisable to test for all four when anaemia is diagnosed. Vitamin B12, together with vitamin B6 and folic acid, ensure the absorption of iron. In disorders of the stomach and/or intestines, like auto-immune gastritis, a deficiency of several vitamins and/or minerals may occur and should be monitored.
Iron
Vitamin B6
High doses of vitamin B6 can lead to neurological complaints such as tingling. In addition, light sensitivity or a deterioration of memory and thinking processes may occur. Avoid prolonged high intake of more than 25 mg per day, unless under medical supervision.
