This seems incredible, but who knows, there might be a correlation.
i recently started taking my daily dose of vitamin D, the sunshine vitamin. I take 1000 IU a day, just before bedtime, from about fall equinox (Sep. 21) to spring equinox (Mar. 21), because there’s mounting evidence that we northerners don’t get near enough of the stuff (generated by exposure to sunshine) during the winter months.The corresponding health risks include multiple sclerosis, bone strength, various cancers and autoimmune disorders — no thanks!
Anyway, i’ve been having incredibly vivid dreams for the past week. More unusual still, i’ve been remembering them (more or less), which rarely happens. Last night’s involved my father in his younger days, a job that i liked but was ducking, and some kind of tropical watersport that made me feel really happy.
I just made the coincidence today between my enhanced dream life and starting to take the vitamin D. Thing is, i also just remembered that my Victoria friend Fil told me a couple of weeks ago that he had to start taking his vitamin D pill in the afternoon, because he was losing sleep over all the dreams he was having — so wild they kept waking him up. I was skeptical at the time, but now….
So maybe there IS a correlation. I googled up “vitamin D dreams” on the World Wide Web and found almost zero references linking vitamin D and nighttime dreams. So, all you vitamin D users out there … let’s do some SCIENCE. Has there been any change in your dream life?

Hello fellow D-abusers,
I started taking 5,000 IU softgels last February and I have since been having really twisted and weird dreams. At first the dreams even woke me up at night and it took me a long while to realize that it WAS just a dream I was having.
After some testing I reduced the amount of intake to 1 pill every other day (never in the evening, because I feel energetic and heated for a few hours afterwards). After a while when my body adapted, the dreams started coming less often and were lower in intensity. I then stabilized to having generally more memorable dreams and some weirder dreams every few days.
Also, a friend of mine started taking 2,000 IU pills once per day and only after a couple of days he came to me saying he’s been having these really psychedelic dreams. I had not told him of my dreams before but I could immediately relate.
Yes, there is definitely a connection between taking high levels of D-vitamin and having really “vivid” dreams if you want to call them that. Sometimes they can be really horrible, sometimes not so bad. Always weird and strong, though. I guess it’s up to your subconscious what kind of dreams You have.
Anyway, good shit.
I kept wondering why you people dream more on D while I dream less. If I stop taking 2,000 IU for several days the long, vivid, involved dreams and aches & pains come back. I did find something, though. It has been reported that often people who take D at night dream more, and those who take it in the morning sleep more peacefully. I’m a morning vitamin D taker.
I just found out from new research that as yet there is no definitive scientific support for the new model of cancer development, the authors of the study say that maintaining proper levels of vitamin D could potentially stop the development of cancer at its very earliest stages.
My mother has always had odd dreams, and she passed it on to me. With that being said, I recently started taking vitamin D, 2,000 IU at noon, and noticed a SIGNIFICANT increase in dreams, and they are definitely more odd than usual!
I too have had crazy vivid dreams since beginning to supplement with Vitamin D. In my case I was prescribed 50000 UI weekly, and so far (3 weeks now) the dream effect lasts all week.
Looks like I have this to look forward to even with doses of 1000 UI once my rx is done and I normalize.
It is a bit disturbing to have all these dream stories and images trying to have a life in my real, daytime world. It’s been interesting, but I won’t mind if this doesn’t continue!
Wow. I thought this was strange! I am so glad to know that I am not alone here.. I have never had this repeated experience of such intense, real time surreal dreaming before. It is like a twilight sleep where I am unsure if I am asleep until something really weird happens or I am somewhere that either does not exist, is impossible or is somewhere I have not been.
I have been going through the same thing! I have recently been taking vitamin D3 ( 500 iu) and I have noticed that I have started to remember my dreams a lot better now! It’s amazing. I am not sure entirely about the vividness of them though because I have always tended to have pretty vivid dreams but now I can remember them a lot better and a lot more details and things that occur. AWESOME!
and p.s. i also want to do some experimenting because theres no real way to overdose on vitamin d3. i mean there is BUT that is a process. we are talking about 100,000 iu over a long period of time. im in no danger.
YAY DREAMS! 😀
Another Vitamin D-er reporting. I too have been taking some extra vitamin D first thing in the morning. My dreams are really weird, too! I asked my co-workers, and those taking vitamin D are having weird dreams as well! :O
You have no idea how grateful I am to find this website. I was beginning to think I was going insane. I started taking a 5000 iu supplement of vitamin D3 right before bed, and though it has helped me sleep better, my dreams have been off the charts crazy, vivid, and I remember them- even if I don’t necessarily want to. My mom got me onto the supplement after it helped her start sleeping better, but when I asked her about her dreaming, she said there had been no change. I’m glad to know that it seems like there is indeed a correlation between vitamin D3 and my dreams of purple ducks beating the crap out of plain white ducks and other, much more disturbing images.
When I was taking 1000 IU Vitamin D, I didn’t notice any differences, but when my doctor increased the dose to 2000 IU, I began having vivid dreams. I take it in the morning but it still seems to impact my sleep (but not in a bad way).
I am also relieved to have found this site…I have been struggling to figure out what has changed in my life that would have such a bizarre impact on my dreams…unfortunately, they are usually in the form of a horrible anxiety dream. Yet, like other, they are much more vivid and I remember them for weeks, when I never used to remember dreams at all. They have impacted my sleep in a negative way though, where I used to sleep soundly all night. Interesting how it affects us all a little differently.
OMG, like many here I have been wondering whether the sudden onset of vivid dreams (which I’ve written about on my blog) has had anythiing to do with the 2500 iu vitamin D I started taking on 23rd Feb. For the record I take mine with my lunch.
How great to find all of you reporting similar experiences!! I always used to have fantastic dreams and I loved it but I’ve had some health and fatigue issues for a while now and my dreams had kind of dried up. I’m really excited about this!!!
I think I feel a bit sharper mentally in gernal as well but I’m not sure. Off now to do more research on this fascinating possible link!
thanks Greg for your initial post and everyone for sharing their experiences….
i used to only dream at the full moon and thought the upcoming Super Moon was causing my dreams… however, night after night for over a week i continue dreaming and it’s still five days away.
what changed? i started taking vitamin D!
i am fascinated that i am not alone… thank you!
Same here… started taking them the other day and the dreams kicked in.
My dreams the last four nights (since beginning vitamin d) are VERY disturbing and seem be part of a sort of twilight sleep. I am only needing about 6 hours but sleeping is SO weird! The dreams are in real time, strange, sort of anxious and very surreal. And I am NOT the anxious type….anyone else experienced this?
Count me in. I am also having vivid dreams after taking vitD3 (1000iu) for the past 2 days. I take it at night. I fall asleep earlier than usual and dreams are coming mostly early mornings until the time I get up. Infact my dreams make me sleep longer than usual as I like the ‘movie’ that is going on and I dont want to break the pleasure of watching it 🙂
Doctor recommended D3 (5000iu) for me. Started one week ago and have been dreaming like Martin Luther ever since!
I thought i was losing my mind. I have been on 5000 iu of vitamin D for about a month. I used to take it in the morning but because of other medication that i have to take first thing in the morning, i have to take my vitamins at least 4 hours later. of course by this time i am at work and always for get the vitamins. So I find myself taking my vitamins late in the evening when i get home, before going to bed. My dreams are so vivid. They are about people I know and they are usually resulting in sickness, death and murder. When I wake up I clearly remember the dreams (or should I say nightmare). Even days later I am still remembering the dreams. I think it is the vitman D late at night.
Similar story as the aforementioned. The dreams I’m having are so unlike any dreams I have ever had. I was thinking maybe its just part of menopause. Thank you for starting this thread. What most strikes me about these dreams is that I seem different. I guess even my dreams I thought were a part of me, silly, but these dreams seem different than me but still me.
started taking Vit D3 2,000 iu every evening with a glass of milk (I was told Vit D works best with Calcium). I am on my second week. The first week I took it in the am. No dreams. Then I read an article that said taking at night was better for absorbtion. Well let me tell you that the 1st night of taking it I had the nicest dream that I somewhat remember. Every night this week I wake to a nice dream and realize that I slept thru the night. I will accept the dream issue if I am finally sleeping thru the night. I have never blogged before. A thank you to everyone who has shared!
Do the dreams calm down at all over time? I have just started taking Vit D, 1st thing in the morning and the dreams are waking me up. Im loving the improved energy but feel unrested from the disturbed sleep.
Hi Helen,
My dreams certainly tapered off after a few weeks. Now i miss the incredible technicolour movies i used to watch every night. I even tried taking my vitamin D in the evening to try and induce them, but they haven’t come back. Oh well … fun while it lasted.

I was sure the Vit D correlated with my dreams being more intense and vivid, and that I can recall them so clearly in detail. Wonder what it is about that vitamin that does that to the brain? Any theories out there? My husband looks forward to me sharing the crazy sagas in the morning. I was concerned, but since most of you seem to enjoy the effect, and miss it when it is gone, guess I’ll relax and enjoy.
One question, I am started on 1000 and going up to 3000mg. Do the dreams increase with dosage going up? Weird.
