Vitamin D3 in Morning Improves Sleep After All (Story 26)
Posted Nov 01 2012 12:00am
Adam Clemans (28 years old, about 80 kg, pharmacist, lives in Shanghai) on a recent post that Vitamin D3 didn’t seem to improve his sleep (“I can’t say I noticed any improvement in my sleep from Vitamin D”). He took 4000 IU in drop form right after he woke up.
I wrote him for details. I said that since 4000 IU was the lowest dose I found effective, he might want to try a higher dose. Adam answered my questions and said he would try a higher dose. Two weeks later he wrote again:
I started taking 4 drops (8000 IU) of Vitamin D3 1st thing in the morning (up from 2 drops or 4000 IU); my sleep seemed to improve immediately and quite dramatically. I had been struggling with middle-of-the-night awakening for a week or so, but after the change I slept like a brick or a baby (pick your metaphor). I would like to experiment with this more before I say I am sold on it, but for now it seems to be working well.
He’d been doing the higher dose for two weeks. Hard to explain as a placebo effect.
