Folic acid -24.6ng/ml, is it toxic level? What are normal values? Symptoms of toxic levels? 43y, fem, on bcomplex with 1.5mg folic acid. Hvy periods.

Folic acid. Folic acid is one of many B vitamins and needed to make red blood cells, white blood cells, and platelets, and for normal growth. Normal levels are 2-17 ng/ml. Am not aware that elevated levels cause any symptoms or disease.
