Zinc and vitamin D - fantastic aid to decent sleep (at last)

Started taking these 2 supplements in high quality form e.g. Chelated zinc plus copper 15 mg and standard dose vitamin d.

All I can say is if the first week is anything to go by the results are life changing - ie up to 1-2 hours more sleep per night consistently.

I have since googled and there seems a lot of research linking better sleep with both these supplements individually - taken together extra boost : )

Anyone else had similar results ...

I keep thinking about this issue - particularly after reading Dr Gominak on Vitamins and Sleep:

However, as a family (siblings) we all seem to have low vitamin D (severe deficiency category) and, even with supplementation, it is proving difficult to shift our levels. I need to give this some more thought.


Great article thanks.

Meant to add the 3rd supplement I am taking extra is B complex in a reasonable strength - also mentioned in the article.

Very positive ...


I found that I definitely needed Vitamin B complex as well as after starting vitamin D and magnesium.

I have posted Dr Gominack's article numerous times on here.

I started getting peripheral neuropathy about six weeks after starting high dose vitamin D supplements. After reading Dr Gominack's explanation and recommendation, added good quality Vitamin B complex, this gave an almost instant cure.

I continue to take vitamin D, B complex and magnesium.

Hadn't considered Zinc, as linked to sleep, but I take that too anyway.

Now sleep extremely well, at least 8 hours every night


Fascinated to see that the protocol works for you. May I ask, did you have any particular issues in shifting your vitamin D levels to the window that she recommends?

Insomnia started after a significant concussion as a child so is now of >40yrs duration. Altho' all of us siblings are categorised as 'severe deficiency', mine is repeatedly absurdly low even by our standards. I think it would mean such a lot to me to be able to obtain some sleep on a regular basis and particularly some REM (I'm rarely asleep for long enough to enter REM state).


I try to keep my vitamin D between 80-100nmol (UK units)

Dr Gominack's units are USA ng/ml

I test regularly, especially as in order to increase at all, I found I had to take 6000iu mouth spray daily. (Approx 2-3000iu to maintain and I sit out in sun a lot)

Found out the hard way that I needed to supplement magnesium first. Couldn't tolerate vitamin D at all before started magnesium, and even after that had severe bone pain for about 6 months

But all this made me realise I had gut issues and malabsorption going on despite no gut symptoms at all.

I have Hashimoto's so it's not surprising. But in 20 years under various endo's no one ever suggested importance of low vitamins.

Diagnosed, after endoscopy, as severe gluten intolerance.

More on my profile

Concussion can apparently affect vitamin D and be improved by supplementing

There are many many similar links too if you google


Did you test first? Vit D is fat soluble and excess gets stored and can become toxic. You need to check your level once or twice a year when supplementing to keep within the range recommended by the Vit D Council which is 100-150nmol/L (or 40-60ng/ml). Also, are you taking D3's important cofactors -

D3 aids absorption of calcium from food and K2-MK7 directs the calcium to bones and teeth where it is needed and away from arteries and soft tissues where it can be deposited and cause problems such as calcification of arteries and kidney stones, etc.

D3 and K2 are fat soluble so should be taken with the fattiest meal of the day, D3 four hours away from thyroid meds.

Magnesium comes in different forms, check to see which would suit you best and as it's calming it's best taken in the evening, four hours away from thyroid meds

Check out the other cofactors too

And zinc should be about half way through it's range.


What time of day do you take the Vit D and Zinc? I'm trying to optimize my results. Thx!


After breakfast

Take thyroxine at night

Real test last night woke at 4 after 5.5 hours sleep 99 times out of 100 for the past decades I would have not got another drop and this time read a little for 10 mins and then slept for 2 more hours

Call me a cynic but if anyone advertised a sleep cure is available drug free what on earth would drug companies do with their sleep products ?


I will never know whether it is just these 2 vitamins alone but in the 2 weeks since following my current regime all the symptoms I inherited have all now gone.

Literally - best I felt in as long as I can remember. It may very well be that my TPO numbers are still not perfect or my TSH is still not perfect and I will get these checked.

Alongside this have been all the ideas I have taken on board from both this website and forefront health website to boost T3 conversion.

This does give hope to those like me with only a T4 levo option and needing supplementary support to create sufficient T3 - I would expect now that when I test again in another month numbers will be more in line.

I will do the more expensive blood test next month to include vitamin levels check just to be sure for long term dosage
