Fabulous version of folate
My husband requires a lot of folate for his methylation cycle (and B12, B6, and TMG). He wasn't able to take enough folic acid since apparently he doesn't metabolize it very well, and this 5-MTHF has been a gift. It gets past the conversion blockade by already being the conversion product.

Need to control the dosage properly.
I bought 5-MTHF to see if my body needed folate. I have been "sick" for more than 20 years where I have fatigue problem. I had many hypothesis on the cause of my fatigue. One of them was MTHFr defect. I suspected I have undermethylation problem as I compared my symptoms to generally known symptoms. So, when I took 5-MTHF with Methyl-B12 and P-5-P , I felt better for a whole week, but the felt even worse the next week. Yup, overmethylation. So, I cut down the amount to half, and felt better back. But it is not constant and stabil. Still working on for the proper amount and timing. A piece of advice for beginners. Try to take excessively for the first 3 days and if you feel better that means your body need them. You will feel so bad after that, but you can then reduse the amount untill you feel constantly better. Oh, and the delivery service is fabulous.I live in Japan but still I would get the supplements after just 5 days of ordering. Even domestic delivaries would sometimes take 5 days. Thanks a million iHerb.
