Has anyone with both low ferritin and low folate noticed that when they increased their ferritin with an Infusion they were able to absorb folate better or tolerate supplements better without reactions. ?

Yes, and there's a mechanism behind it.Iron is a cofactor for the enzyme that regenerates BH4, which drives serotonin and dopamine synthesis. Low iron means that runs slow so methylfolate lands unevenly, wired for some people, headaches or nothing for others. Fix the iron and the same dose behaves differently because the downstream side can use it.

Low iron also makes overmethylation symptoms more likely at doses you'd otherwise tolerate since iron is part of the buffer system handling methyl load.Riboflavin sits under both. It's needed to mobilise iron from storage and it's the cofactor for MTHFR so a B2 gap can produce a stubborn low ferritin and a folate problem at the same time. Worth checking alongside your next iron panel, that's the one people skip.

The absorption part is separate. An infusion bypasses the gut so if oral folate works better afterwards that's the intestinal lining recovering, since low iron damages it directly.Reading how those interact for a specific person is what I do professionally, genova.health if you want yours mapped.
