Thanks for the list.
I don't really see a problem with B6 here. But I do think based on your health status, that high dose folic acid taken long term without any B12 can begin some neuro problems. Most B50mg complexes have 400 mcg of folic acid, and you are taking 400 more. If you are low in B12 and don't know it, then some nerve issues may appear. I don't know if you take acid lowering drugs or your age etc so this is really just a "shot in the dark".

It is not typical to get B6 side effects from one dose.
There could be other reasons for your symptoms. Compression palsies occur in people with diabetes, Charcot Marie Tooth neuropathy, MS, low magnesium, low potassium, and all sorts of things.

Your supplement B'calmd has very low magnesium and calcium levels. I wonder why they are included even in there?

Also taking large amounts of phenylalanine can raise blood pressure in some people. It would be prudent for you to have that checked.

If you consume alot of salt daily from snacks and soups, or MonoSodium Glutamate, you can get numbness and tingling in the extremities. MSG is added to many processed foods, and is not good for the nervous system.

That's all I can see at this time.
