An estimated 85% of synthetic folic acid from supplements and fortified foods is absorbed by the body, compared to just 50% of natural folate. This can lead to a build up of unmetabolized folic acid (UMFA) in the bloodstream, raising potential health concerns for some individuals.

While folate is a crucial nutrient, an excess of its synthetic form, folic acid, can pose health risks, including masking a serious vitamin B12 deficiency. High levels are most often caused by over-supplementation, not a diet rich in natural folate from foods.

Recent studies have detected unmetabolized folic acid (UMFA) in the bloodstreams of a large portion of the population, raising questions about whether **does folic acid build up over time**. Unlike its natural counterpart, folate, synthetic folic acid from supplements and fortified foods can accumulate when consumed in high doses, potentially leading to adverse health effects.
