MTHF'er

My wife has been taking this methylfolate supplement daily to support her energy levels and overall mood, as it's the active form of folate that her body uses more efficiently. The capsules are small and easy to swallow with no unpleasant taste or stomach upset noticed so far. The bottle arrived well-sealed and undamaged from iHerb, and the shipping was quick this time.

Good one

I bought this because it’s on sale. Seems high quality quatrefolic. Trying to get pregnant and have the mutated gene so I have to take this type. But the dosage is too high so I might take half dosage only.
