There's an old post on this somewhere that had a 5mg quatrifolic tablet giving the same feeling as 3.7 mg of metafolin.
In other words, the quatrifolic says it has 5mg metholfolate, but it really doesn't work out like that in terms of how it feels. It feels like only 3.6 mg of methfolate. We confirmed this with our own experimentation.
If you take that into account, quatrifolic and methylfolate are similar in effect.
We take a fix of all three:
- quatrifolic in the morning first thing and last thing before going to bed (to get through the night)
- folinic with b2 through the day
- metafolin very occasionally (almost never now).
We didn't start like that. We were taking metafolin for a long time, until we got the B2 levels in the body up.
Some other post on here somewhere happened to mention that, if you don't have genetic problems, then B2 with folinic should be fine. Since our patient is a growing teenager, I liked the more diverse benefits of folinic for DNA synthesis etc.
Hope this helps.
