Do you recommend folic acid or methylfolate?Best to find supplements that are as pure as possible and that don't give reactions.
Diets low in folate/folic acid, illness, malabsorption/digestive issues reducing folate absorption, excess stress, will deplete folate. If people avoid certain foods due to poor digestion of them (plants are high in folate generally, but many do not digest them well and eat them sparingly or do elimination diets) or follow extreme diets like carnivore and dont eat enough organ meat daily for folate, you will get depleted of folate.
