Few years ago a research team at the Institude of Medicine established an upper tolerable limit of 100 mg B6 per day for adults. Taking doses of less than 500 mg already caused nerve damage. So you guys should really be carefull here in taking such huge dosages. I recommend against doing so. First of all because it has been proved to be dangerous and second, because way lower dosages are already effective. I tried a vitamine B complex which has 8 mg (400% of daily needed dose) of B6 and it worked like a charm for me the first few times I used it. Dream recall went as high as remembering like 10+ dreams a night if i put effort in it, and also dreams became more vivid. However after a time the effects became less and less, maybe because my body build up a tolerance (I'm not sure why). I tried a vitamine B complex (it contains all the different B vitamines at approximately 400% daily dose) because it is known that using B-complex has way more effect on assimilating all the vitamines into your body. So all in all its a very good way to increase your dream recall (at least for a while) but be carefull not to take dosages above 100 mg for prolonged periods of time (and stay clear of using dosages around 500 mg because you dont want nerve damage&#33.
