Does long-term folic acid lead to liver function damage?

Folic

acid is a B vitamin that plays a key role in cell division and growth. It is also essential for fetal neural tube development. Under normal circumstances, taking folic acid for a long time within a reasonable range according to medical advice generally does not cause liver function damage, because folic acid is a water-soluble vitamin. Excess folic acid will be excreted through urine and will not accumulate in the body. However, if folic acid is taken in large quantities and for a long time without medical advice, it may interfere with some metabolic processes of the liver, resulting in abnormal liver function.
