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?

No, but I take mine in the morning.
Where are all your loyal subjects? So far this trial is tanking….
I take mine in the a.m., but have wild dreams anyway. One of the pleasures of passing “mid life”.
Sounds like yer anima is risin’. You know, Vitamin J for Jung.
I take a Vit D supplement at dinner, and have also started having very vivid dreams in the last week or so. So now we have a sample of 3 … not much statistical validity in that.
However, I found your blog via Google which also raised this link http://answers.yahoo.com/question/index?qid=20090420062536AAJnDNp which has a pharmaceutical company employee giving a bit more evidence of this effect.
not much of an answer, and I am not sure they have a lot to back it. Seems like there is more in this blog then on that site.
I’ve been logging my vitamin D intake over the last couple of weeks, and have noticed a rough correlation between the remembered vividness of my dreams and taking a 1000 IU pill at dinnertime or later.
As the link in the above comment suggests, it’s unclear whether the dreams are wilder and more vivid or i’m just remembering them better.
It ain’t science but it’s interesting. But now i’m moving on to other things. Still taking my second vitamin D pill in the evening, though.
I started taking vitamin D about a month ago and I have a crazy dream just about every night. My dreams are more vivid, they seem so real and I remember them throughout the day… crazy but I have a friend who also had the same thing happen. I told another friend to start taking D and see if he notices the same thing… I think we’re on to something though!
ME TOO!!! I was looking all over the internet to see if it was just me having these wild dreams. They started exactly at the time I began to take a Vitamin D3 supplement (I take them before bedtime). The strange thing though is that I keep having different dreams with the same people in them and they are so vivid.
I never remembered my dreams until two weeks ago when I started a 1000 IU Vitamin D supplement. The morning after I had taken the first pill, I commented to my husband about all the strange dreams I had the night before and how I could recount all the details like never before. For the first three days I took them with dinner and I was amazed at how I remembered all the details of my dreams the next morning! I decided to take the Vitamin with lunch, and since then I have not been aware of any dreams.
I found this page while trying to answer the same question. Ive been taking 5000 IU vitamin d in the morning for the last month, with my vitamin C drink which ive done for years. I have been having intense dreams every night since, unsettling at first, but now acustomed and quite enjoy them.
Also I am a migrane sufferer, I have not suffered with a migrane in this time, I also take 5 HTP (pre curser for the production of seretonin) to reduce the onset of migrane (low seretonin) 🙂 I have read else where the dreams are from higher levels of seretonin, which is a pre curser for melatonin (puts you to sleep)
I started taking 6000 iu’s of Vitamin D3 last week after my blood test results showed my Vitamin D level was as 9. And yes, I have been having vivid dreams every night since then.
I noticed immediatley that my dreams were way more vivid and that I could recall most of the dream the next day right after I started taking vitamin D in the fall as an alternative strategy to the H1N1shot. I also sleep much better, no bathroom breaks anymore. Currently after much research am now taking 5000 iu daily plus a weekly visit to the tanning bed for about ten minutes. Will have my levels checked sometime.
I googled “vitamin D vivid dreams”- because of my experiences. So count me in!
Yes!!!!! The dreams are strange, vivid and memorable esp. when I take it late at night.
Yep, me too. More vivid, memorable dreams. Friend had the same experience as well.
Maitake D Fraction extract (not related to Vitamin D) had similar effects as well.
I know I’m late, but I take 1000iu of vitamin D at night and have had the same thiing hapen to me, wild, vivid dreams that I remember.
My doctor just started me on 5000 iu of vitamin d3 this past Monday and I’ve been having very vivid dreams (and sleeping better, it seems) ever since – almost immediately.
I found my way here because I googled “Vitamin D” + dreams. I searched for this because I too have noted a very noticeable uptrend in my dreams since I started taking Vitamin D. I noticed this because I moved to Sweden in January and knew I wouldn’t get enough sun. That said, I also notice the same whenever I get two or more days of continuous exposure to the sun. So for me it seems that Vitamin D the natural way or in supplemental form (D3) has this effect.
Okay, so I thought I’d Google it on the whim that there would be a correlation between Vit D and vivid dreams. I guess I’m not alone on this. I wasn’t sure if it was the 1000 IU of D3 or the 1000mg of Vit C I started taking recently.
Like everyone else the dreams feel real, more so than any dreams I’ve ever had. I also remember most everything that happened unlike typical dreams in the past.
I feel much more rested and find I only need 6hrs of sleep most days and I’m up and ready to go again. Actually, my body or mind doesn’t let me sleep longer which I love. I could probably sleep a good 12hrs before and still feel tired.
I’ve been looking for a link between vitamin D & dreams too, but in my case, I find that taking vitamin D makes me dream less. Normally I have many very vivid dreams every night, and wake up exhausted. I have better sleep with D.
Hey guys,
Just came across this page. I started taking 5,000 IU of vitamin D3 and am getting REALLY vivid dreams very night. I used to suffer from insomnia too. I was told that it´s not that I´m having vivid dreams, but that I´m actually dreaming and reaching a deep sleep state as opposed to before.
Here i am (the original blogger) a year later. I’m still taking Vitamin D, roughly from fall to spring. Like many commenters above, i have upped my dose to 2-3-4,000 IU per day (depending on how much sun i get in a day) from fall to spring. Thing is, it doesn’t seem to have any noticeable effect on my dream life these days. The vivid dreaming, sadly, has disappeared. I miss it.
Hmm … Vitamin D has a very low toxicity. Maybe i’ll take 5,000 IU this evening and see if there’s any effect. (My doctor is spinning in his grave right now. But then, why would i take health advice from a dead man?)
Well, after a few nights’ experimentation, i have concluded that the vividness of the dreams has definitely faded. What i do seem to get most nights is long, involved novel-like dreams — sweeping sagas that go on and on. I remember mostly just the last parts of the dreams when i wake — that and the fact that they were very complicated.
Still taking my D. We’ve had little sun here in Tofino this summer, and we’re deep into the winter greys now. I’m holding at 2-3,000 IU a day, depending on how much sun i get during the day. Friends of mine swear by 5,000 a day. Sounds like a lot, but i read somewhere that in strong sun a Caucasian body will make 20,000 IU an hour. (Darker skins apparently make less.)
