For further explanation 
You can’t take 1g B6!
more than 100mg can cause nerve damage
B6 has definately had an effect on my dreams this week. Although it doesn’t trigger lucidity or anything like that, I have noticed that my dreams have a definate linear continuity that is usually missing from NDs in the past.
Instead of having completly random jumps between the chaos of unrelated events, everything progresses in a more organized storyline model. In addition to this, waking and returning to sleep has been regularly dropping me back directly into the same dream at the same time, like putting the story on pause.
At first I thought because everything seems more logical, it would be harder to recognized weirdness, dreamsigns, and thus enter lucidity. But there are still plenty of things out of the ordinary to notice, except everything seems to hold together better. This leads me to believe that B6 would make it easier to stay in the dream after lucidity is obtained. Also, if one wakes up from a good dream, it can be re-entered much easier.
Does anyone know if the effectiveness of B6 decreases over time and requires larger doses?
My guess, since your daily need of vitamins is set on the same amount for your total life is that you don’t require larger doses. If the body would gain toleration for B-6 and after time you would require more to have the same effect, wouldn’t this also be with your daily need?
Just my thoughts on this, not an ensurance. 
Its my experience that a B vitamin supplement can really help with 
ENERGY which I would percive as a block with lucid dreaming… B12 especially is the primary ingredient in human respiration of food (other than O2)
I’ll summarize my experience with B6 here:
After watching Waking Life I was ready to start lucid dreaming wholeheartedly and I remembered reading the same Erowid experience ( erowid.org/experiences/exp.php?ID=2247 ) report about Valerian, B6 and Melatonin. I went to the grocery store later that night and picked up 100 50mg tablets of B6 and 120 Melatonin sleep support pills that also had 10mg of B6 each. I didn’t really know where to get Valerian root, so I decided to try out the other two. At this point I had virtually 0 dream recall, meaning any remembering of dreams were isolated and literally 3+ months in between. Sorry about the length, but I think my being thorough will help validate my conclusions.
Night 1: 210mg B6, 3mg melatonin - when I woke up i remembered the tail end of my dream and wrote it in my DJ
Night 2: 530mg B6, 9mg melatonin - no dream recall
Night 3: 540mg B6, 12mg melatonin - possibly a lucid dream, but if it was there was very little clarity & control, although I did know I was dreaming and tried to control things
Night 4: 540mg B6, 12mg melatonin - was able to maintain consciousness through what I think were the first four phases of sleep (attempting WILD), but then I had to use the restroom, so I scrapped it.
Night 5: 640mg B6, 12mg melatonin - remembered my last dream, recorded in DJ
Night 6: 0mg B6, 0mg melatonin - remembered my last dream, but didn’t write it down and forgot it later
Night 7: 540mg B6, 12mg melatonin - wrote about one side of a 8.5"x11" sheet of college ruled paper (which is what I use for my DJ) describing a very vivid dream
Night 8: 810mg B6, 18mg melatonin - remembered multiple dreams and one very vividly, which I described over one and a half sheets of my DJ
Night 9: 1000mg B6, 15 mg melatonin - My first lucid dream since one that I remember having in childhood! I also remarked to myself in the dream about the clarity and how lifelike it was. I was able to fly and I materialzed objects that I wanted, although without realizing I had done so until afterwards. I recorded it over 2 pages of my DJ.
After this I skipped a night and then took 58mg B6 and 24mg melatonin and had a very vivid dream that took over a page and a half to describe in my DJ. That was three nights ago and I have stopped taking B6 and still have remarkably improved recall and clarity. As far as whether B6 works for dream potentiation or not, I would say it definitely does, though most effectively in doses over 200mg. Also, I suggest that if it doesn’t work for you on the first night and you are still willing to try it, I think there is some initial barrier or something because the most noticeable effects started happening on the third night of taking them.
As for negative side effects, from what I’ve read on Wikipedia and on the link Magic_Dreamer posted earlier ( ods.od.nih.gov/factsheets/vitaminb6.asp ), the overdose of B6 (above 100mg per day) causes temporary deadening of nerve cells and goes away shortly after discontinuing use. From my experience, on either the second or third night I felt a tingling sensation while going to sleep, I haven’t noticed much difference from before taking B6 except that occasionally textures would feel enhanced. Most of the time everything felt normal though. Now that I have not taken any for three days, I have been starting to feel more tingling sensations, which I assume is my nerves coming back to normal. Also, the NIH article said that B6 deficiency can cause dermatitis, and I normally have fairly persistant acne despite washing my face twice daily. But over the last couple weeks my face has been clearing up a lot, and it didn’t occur to me that it might be the B6, until I read that and realized that my acne has been gearing back up again over the last day or two. I can’t really prove any of this last paragraph, but from my experience with it and the bits of reading I have done on it, those are my conclusions.
From now on I will probably discontinue B6 for a week or so and then take 100 or 150mg daily with 1-2 day breaks every week or so to continue developing DR, and hopefully help my skin. Hopefully this was helpful 
Eat Marmite! 
Love it 
or hate it, it contains B vitamins, especially B12.
Vitamin B is amazing. I have some Junior B Complex pills. They have 25mg of Vitamins B1, B2, B3, B5, B6, and 50mg of B12.
I took one before bed several nights ago. I had a huge Lucid Dream which was really vivid. The next night I did not take another pill, but I think my body still had some of the vitamins from the first. I had 2 Lucid Dreams in that night, they had perfect recall and both felt more real that real life.
The Next two nights I had no Lucid Dreams and not very good recall.
Last night I took another pill before bed. I had 2 Lucid Dreams.
These pills must really work for me. I’m waiting to see if I have more Lucid Dreams tonight without taking another pill.
Hi there. Personally I’ve never tried supplements and personally don’t feel like to. I just posted here to say one thing: if you check en.wikipedia.org/wiki/Cyanocobalamin, it talks
about side effects of too much B12. They seem somewhat bad, but not like they could kill you outright. Still you might want to check that.
I eat marmite quite a lot 
I might have some tonight, just before bed and see if i notice anything.
whats the longest time before sleep you could take b6? i took 200 mg at about 7 o clock and another 100 at about 11, asleep at 1. is that to much of a gap between pill and sleep?
davide- out of all the things i’ve done that should have killed me, i’m not to worried about vitamins 
Hmmm that’s interesting. I normally eat a lot of Marmite but I haven’t recently. Anyway today I noticed lots of smalls lumps (like blisters, one burst) on the tips of my fingers, above the nails, on the last knuckles. Could it be a symptom of too much B12?!
“Dermatologic: Itching, rash, transitory exanthema, and urticaria have been reported. Vitamin B12 (20 micrograms/day) and pyridoxine (80mg/day) has been associated with cases of rosacea fulminans, characterized by intense erythema with nodules, papules, and pustules. Symptoms may persist for up to 4 months after the supplement is stopped, and may require treatment with systemic corticosteroids and topical therapy.”
“Nicotine can reduce serum vitamin B12 levels.” I stopped smoking today too.
Any of these? Dunno, I’m not a doctor…anyone know what it might be?
It’s probably nothing to worry about, I had it a while ago. I think it is sweat under the skin. It was when I was doing my exams and my hands were sweating alot. One of them burst in my mouth, it tasted salty, like sweat.
Nasty! I’ve never heard of or had sweat under the skin before! How big were yours? These ones are small - 1mm.
Yeah, like yours they were about 1mm and I had them all over the sides of my first fingers. They went away after about a month.
at 10 i took 50 mg of it (1 pill lowest dosage i could find) and im guna go to sleep ill post my results tomorrow
That was interesting, thanks for posting that!
Whenever I’ve tried large doses of B6, Valerian & Melatonin (sometimes Kava too), I’ve done it as one-offs, single attempts … I think maybe if I gave it a few days & tapered up (to let my body adjust to the supplements, I guess) it might be more effective.
I think I’ll try your approach & see what happens (I’ve already got some B6 & Melatonin, plus I might add some Valerian to see if that works too). I might not have the same results as you, but anyway it’ll be interesting to see what happens (especially if it helps reset my sleeping patterns, also I get kinda dry acne too, not bad just enough to be annoying, so maybe the B6 might help wth that… ?)
Also, on the general subject of B Vitamins & side effects etc, the following reports are from the European Commission (woohooo!! 
):
B5 toxicity:https://ec.europa.eu/food/fs/sc/scf/out80k_en.pdf
B6 toxicity:https://ec.europa.eu/food/fs/sc/scf/out80c_en.pdf
B12 toxicity:https://ec.europa.eu/food/fs/sc/scf/out80d_en.pdf
I haven’t read them properly yet, the B5 & B12 reports seem quite short & don’t seem to mention much in the way of toxicities (side effects) with these two, however the B6 report is much longer & DOES talk about toxicities (reversable ones) at higher doses, when it’s taken over longer periods of time. I haven’t read them properly though as I only just found them… 
…thanks thats just what i wana hear lol but i didnt have any sort of spectacular dream but i remembered one perfectly which took up 3 3/4 pages of my DJ im not guna bother posting it cause its soo long but yea i had amazing recall
For the past two nights I forgot to take my nightly B6 100mg pill that I have been taking for about 2 months now. Then last night I remembered to take it again and had my first Lucid Dream in about 2 weeks. Coincidence? Or maybe it had to do with visiting this site yesterday for the first time in a few weeks… Hmmmm…
Maybe that’s a similar effect to ‘cycling’ supplements, where you skip days occasionally, especially if you’re taking them over a period of time … for example, if you take the B6 (or whatever) for 5 days, and then skip 2 days (5 on~2 off) that stops your body getting too used to it, which makes it more effective. Also, you might notice a much bigger effect on the first day back ‘on’ too.
… that’s the theory anyway, I guess there’s no reason why it shouldn’t work with B6 as much as with any other supplement?
