Hi Kira, I did some digging around for you, results were a bit variable, but here goes....
So Neurofolin contains L-methylfolate as the "active ingredient." which is a vitamin B group derivative. Therefore it can be classified as a health supplement and so does not really have to be licensed as a medicine. As a result of it being placed under the grouping of the vitamin and the mineral market, it can be widely available to the general public. Although it is claimed to be used for depression, the loop hole used to avoid it only being available via prescription is by not having a direct claim to be used for the treatment of depression. The magic words "
may be useful for the managment/treatment of...." is permisable as its not a direct claim. and so is not subject to the stringent restrictions/regulations of actually classified medicines. (Don't know about you, but these technicalities are beginnning to give me a head spasm :eek
.
Anyhow, L-methylfolate is still undergoing research. The basic claim is that it can be used as an adjunct in the treatment of depression, whereby it is thought it may help to augment the effect of currently prescribed meds. It is thought to be able to increase the production of the neurotransmitters serotonin and dopamine which play a role in mood regulation. Now I'm just hypothesing here, but if you are on any prescribed meds for depression or anything else for that matter, then there could have been an interaction causing you to feel the way you did. Or it could have been just a reaction you had to only Neurofolin.
As you are probably aware, people can react differently to medicines and vitamin (and herbal) supplements. Things to also bear in mind generally regarding the vitamin/mineral/herbal supplement market, is that the level of active ingredient actually available for absoption can actually vary between manufacturers hence the potential for variable responses.
The jury is still out on L-methylfolate regarding its effectiveness (and safety) for depression as more studies are needed. I've provided a link here which may help to illustrate this :

All this draws to mind the time when St Johns Wort first hit the market for helping with depression. At first it was hailed as the "feel good" or "sunshine drug" because if its apparent effectiveness. However, it had a propensity to interact with so many drugs, including those for the treatment of mental illnesses, resulting in serious side effects so now it is hardly recommended.
In terms of safety, Kira, (and anyone else brave enough to have read up to this point
) please always let your doctor or pharmacist now should you wish to use any over the counter supplements in case they might conflict either with your prescribed medication or an existing medical condition.
Phew, that's me done now, hopefully this will have earned me the Nobel Peace Prize or at least one cold beer:p.
