Until recently, people were careful with the use of folic acid in daily life (pregnancy period does not count!). This is due to scientific claims that, especially in people over 50, a high level of folic acid in the blood in combination with a low level of vitamin B12 leads to faster cognitive decline in addition to poor brain function.
The recent TILDA study from Ireland has proven the opposite. TILDA is the largest study on the interaction between vitamin B12 and folic acid and their influence on cognitive functions. 3,700 Irish people over 50 years of age participated in this study. No evidence was found that a high level of folic acid increases the risk of cognitive decline in people with a low vitamin B12 level.
Moreover, participants with normal vitamin B12 and higher folic acid levels, performed even better in cognitive tests than participants with normal folic acid levels.
