Folic acid only has limits for people who take it without B12.

In people with low B12 it can lead to nerve damage.

Typically 800mcg is the OTC maximum for it... If you take high dose you need blood work to assure your B12 is not below 400pg/ml. If you take B12 properly with the folic acid and stay below 1mg a day folic, you should be okay.

Thanks for the reply mrsD. I usually take the morning vitamins as soon as I wake up, shower, prepare breakfast then eat so I take em on an empty stomach about 20 min before eating. I've had really good results doing this compared to the headaches and symptoms I was getting even from the shower water hitting my head and the shower fan being on a while back. Thinking back to how bad I felt back in the summer I feel lucky to be at the point I'm at now.

I'll tone down the Vit B complex and read a bit more about all the different B vits. It's amazing all the different functions that they affect or are a part of!?! I'm almost done the 100 complex so next time I'll get the 50 complex and see how it feels.

I feel fortunate that the numbness I was getting on my top left teeth, cheek bones and temple bones have subsided a couple notches on the symptom scale the last few weeks and head pressure is almost not a symptom I'm getting anymore : ) I've also been able to start listening to music again with little to no symptoms. . . it might sound silly but it's been a milestone step for me lol

I won't rant on but I hope anybody just starting to deal with PCS symptoms looks into a vitamin regimen. it's the one thing I've found has really allowed me to get back to somewhat of a normal routine again.

Keep positive and keep the recovery going guys. I'm ten months post concussion and I would say I'm 85% or so thanks mostly to the vit regimen I think.

I'm taking supplements now for almost 2 weeks(the whole fraction mentioned on this thread). When can I expect an improvement, or let's say how long need the vitamins to work?

And also, is it better to split them over the day?

Well I'm not exactly sure bud, I'm not an expert or Dr, just a guy that has been suffering from PCS ever since I sustained a concussion 10 months ago and have gotten relatively better. I suffered PCS pretty bad for about 7 months to the point that I could barely work and only part time at that when I was able too. For the past 3 months I have experienced quite a rapid improvement in my symptoms and the only things (variables) that I have really changed to correlate with that time is easing off the naproxen 500 I had been taking for about 6 months, starting a vitamin regimen and starting work full time again. Taking vitamins and the improvement I got maybe have been a coincidence. . . . .but I doubt it. I take most first thing in the morning and then I take vitamin D and a B complex throughout the day. This has worked for me. Other people have had different regimens work for them while taking them at different times so it's something you'll have to experiment with.


From my own experience, this forum and talking to other people with concussions unfortunately either pre-existing conditions that were tolerable/unnoticable prior to the concussion or brought on by the concussion can make recovery an especially difficult process. Finding out if you have an underlying something that might be extending your time for recovery is really THE most difficult part of concussion recovery.

I myself found out I was hypoglycaemic and that this was one of the triggers for the worst of my PCS symptoms. I doubt the concussion brought this on, I probably had it for quite a while and just didn't really have it bother me that much prior to getting concussed. This was one of the personal things that I had to try and 'fix' in order to minimize PCS. For me, luckily, I found out about it and I'm trying to compensate appropriately for it though diet. There's a whole list of conditions that I'm sure can make concussion recovery a prolonged process and every concussion sufferer could have any number of these underlying conditions I'm sure. How they all interplay to make concussion recovery prolonged nobody knows for certain yet.

So to answer your question I don't know when vitamins will start easing your symptoms bud. I wish I could tell ya. I just know that for me they helped tremendously and from this thread I've gathered that a lot of other people have had benefits from them. Sorry I can't be of anymore help to you but I do wish you as quick a recovery as possible. If there's anything else I could try and answer for you I will

I have always taken the whole regimen at one time. I usually take a B-12 separately with my 5-HTP and L-Theanine when I first get up.

In my experience, it is better to take them all at once than to split them up and forget parts of the regimen.

It helps this thread if we keep off topic discussion to the main forum. Otherwise, it can be a lot of comments to sort through.

Could B50 be taken with B12-methyl at the same time under tongue before meal?
What do you think?

I read somewhere that B12 is best bioavailable under tongue.

It does not matter oral vs under the tongue. There are new studies showing oral works fine. Just make sure if you choose to do under the tongue you do so on an empty stomach as well, since the B12 dissolves in the saliva and you swallow it that way
too.

Some people get heartburn or upset by B50 complexes, so you can take that after a meal.

Do you have to take b12 orally on empty stomach also or is this just if you take it under the tongue?

Both should be on an empty stomach. This insures you get the
B12 if some of the sublingual fails. I personally don't think much is absorbed under the tongue. It is mixed into the saliva and you swallow that. Historically it was thought that sublingual worked, but studies are showing that oral is just as good...so I think it is the saliva carrying the B12 orally into the GI tract. Once there it can be bound into food...and that prevents the passive absorption there. Hence doing this with no food present.
