It is still pretty unclear to me why you feel you need B6. Are you an American? It's a little hard to understand what it is you are trying to say i your posts. I'm wondering if English is your second language.
There is very little evidence to support that there is any benefits to taking vitamin supplements. And taking too many can be harmful. So watch your intake, do some research and find out what the recommended daily allowance is and make sure not to get too much. If you feel that you need a certain vitamin, you will be better off eating foods that are high in that vitamin. As far as B6 goes, if I understand correctly, all of the B vitamins work best when taken together, so you may want to consider a B complex instead of just B6. But be careful taking it too close to bed time, as they can cause slight sleep disturbances, and likely will give you very vivid dreams, which is kinda cool, I've tried it

. B complexes are also slightly diuretic, so you will need to increase your water intake. Take note, that by water I am not saying pop, sugary juices, or coffee. Water. Pure H2O! Also, if your B complex contains niacin, then be careful, a high dose of niacin can be extremely unpleasant!!!!
You will also get some benefit from taking a fish oil supplement. Especially with a B Complex. You may also want to do some research and see what minerals go good with B vitamins and try to get some of those minerals. If you are feeling stressed out, or tense, a magnesium supplement can help tremendously. There is far more evidence to show that mineral supplements are more effective than vitamin supplements.
