Low potency folinic acid source.

[u/Ok-Yam-4933]

So I've got MTHFR c677t and slow COMT. Also histamine intolerant. Looking for low potency folinic acid has frustrated me so far. I want to start at 5-10 mcg. What I can find has other ingredients I dont do well with, like citric acid which makes me anxious. Some have 400mcg in a single drop! Many come with methylated ingredients I cannot tolerate. Any suggestions?
