Vitamin D supplements and insomnia?

Someone asked me this today, although supplementing has markedly helped their CFS symptoms, esp day fatigue & painful joints, but they're wide awake at 3am and can't get back to sleep. Familiar?

I too am wide awake in the early hours but have done this way before supplementing, but sleepy in mornings - so is it the circadian adrenal thing coming to the surface next? or by taking sunshine in a drop am I expecting it to be daylight?

Thoughts anyone? (Obviously tonight it's helpful to deal with the Santa thing for young ones! and generally to help remember to put the sabre tooth cat out) Jane :D x

  • I had insomnia even though pains/aches/stiffness had gone since adding T3 and then went onto dessicated. When I switched to Naturethroid I have slept, more or less, normally and waken refreshed, warm, and have energy all day. I also know that some people have different reactions to meds.

    Since beginning Naturethroid in May (I had tried a couple of desicated before that) I have an occasional off day but I still feel good. I supplement with Vit D and Vit B12.

    It is trial and error I think but shortly after beginning Levothyroxine I had widespread body pain/stiffness as well as tachycardia and palps.I saw neurologist and cardiologist but (as usual) nothing wrong. When I stopped Levo, heart calmed down and pains went.

  • Hi Shaws - I've yet to get the thyroid treatment stage. I do seem to be waking with palps again 'tho, hate 'em! Glad you're doing well on Naturethroid. Merry Xmas - back to peeling sprouts! J x

  • There have been quite a lot of reports from people who find taking Vitamin D3 supplements keeps them awake. Most seem to find taking Vitamin D3 supplements in the morning solves the problem. Vitamin d is a fat soluble vitamin so is best absorbed with food or a meal containing fat.

    Human DNA is set to produce 10,000 ~20,000 iu Vitamin D3 from Dawn to dusk from sunlight (UVB) exposure of 7-Dehydrocholesterol molecules near skin surface.

    From Dusk to Dawn our pineal gland should be churning out Melatonin to keep us asleep.

    It is important to try to maintain a good circadian rhythm.

    As well as trying to ensure we get exposure to BRIGHT LIGHT during the day (bright light especially combined with moderate exercise) helps reset circadian rhythm it may be worth putting the free download software program FLUX on all LED digital displays (PC, Laptop, smarrtphone, tablet etc) so the screen is less bright at night and less likely to prevent melatonin secretion. Mercola has many articles on improving sleep hygiene.

    Melatonin is much underrated hormone. It matches many of the actions of vitamin D3. Most people don't get sufficient of either.As well as taking your vitamin d earlier in the day it may be worth taking a low dose TIME RELEASE melatonin supplement an hour before bed and maybe another when in bed to help maintain circadian rhythm.Start with a low amount as some people have vivid dreams initially with melatonin.

    Traditionally living populations in East Africa have a mean serum 25-hydroxyvitamin D concentration of 115 nmol/l. 46ng/ml which rises with age and when pregnant.

    We are probably best advised to keep our 25(OH)D around the 50ng/ml ~ 125nmol/l found in humans living as human DNA evolved, who also have the benefit of dark nights.

  • Hi Ted,

    I take Vit D in the mornings with milk, I will make sure they know this. I think they go to bed quite early so if Vit D is helping, of course you will be less tired!

    I was wondering about the melatonin connection too, that's interesting, and avoid bright light in the evening, it all makes sense. Thanks, Jane :D

  • Do you have any recommendations for a good melatonin product please Ted?

  • I use Natrol time release melatonin

    The half-life is just 40 minutes so it's better if you want to sleep through the night if tablet dissolves over a longer period.

    You'll find it's cheaper from the USA. I use Iherb but Vitacost and others are as cheap.

    Beware the 20% import VAT on orders £15 or more

    UK post office adds £8 to collect the tax and make you go to the sorting office to pay and collect.

    You need to start with a low dose and work up as required as you may find you get vivid dreams.initially.

    I use it because to empty my bladder I have to self-catheterize and it's a bit of a fiddle doing that at 3 am.

    Melatonin helps because as well as improving sleep quality duration, it also reduces urine production (less pee) and also relaxes bladder wall muscles (increased capacity) so no need for the 3am visit.

  • Thanks Ted - that's really helpful - I'll give it a go.


  • Hi

    I love taking Vit D3. My level was 28 in January 2012 and went up to 135 a few months later after taking 5,000 IU D3 a day.

    I have had no bad side effects of any of the meds and supplements I have been put on, and vit D3 has cured the nasty bone pain I had had in my fingers for a few years. They don't hurt at all any more.

    I have never suffered from insomnia, sleeping is my hobby and apparently my biggest talent haha! I do take my vit D3 with breakfast though, so maybe if I took it at night it would affect my sleep, I don't know. The same applies to my DHEA.

  • Hi I have always been like this if thyroid "off". now just sometimes but, before I started treatment many years ago, I was like this every night and ended up with just a few hours sleep a night. thyroid was never thought of then.
