So question... I didn't know there was a difference in folate and folic acid... I just looked at my vitamins and extra folic acid pill.. my prenatals say folic acid... my extra supplement I take says folate as folic acid... help me understand the difference... I guess I'm covered since I'm taking both???
Folate is the naturally-occurring vitamin B9, found in foods such as pulses, asparagus and green leafy veg. Folic acid is an engineered version which is turned into Folate (dihydrafolate I think) by the liver.
Obviously as folate is natural it is the form best taken by the body. Most prenatals contain folic acid.
So, both folate and folic (once the latter has been converted in the liver) work towards preventing NTDs in the unborn child.**
Most people - even those without ms - won't get the recommended amount of folate through their modern Western diet, so supplementation in some form is absolutely necessary. I'll be honest though, here in the UK I have never seen folate instead of folic in a supplement.
From what I have read quickly today, the concerns appear to centre around longterm (ie lifelong) supplementation and fortification with folic acid. In the US fortification of food is mandatory, but in the UK it is not and we are subjected to much less dietary synthetic folic acid than our American friends. When not ttc or pregnant, dietary natural folate should provide enough B9 for a normal person and so folic acid supplements are not required.
**As an aside following Ruby's passing we participated in a clinical trial called PONTI - Prevention of Neural Tube Defects by Inositol, the theory being that Inositol (another B vitamin) may do a similar job on baby's neural tube in those of us who don't respond well to folic acid. Currently awaiting the results, but we got DS out of it
I've wibbled on again, sorry! How's this:
Folate = natural.
Folic = synthetic!
