Paleo Hacks has a thread about timing of Vitamin D3. Better in morning (my and several other people’s experience) or evening (Robb Wolf’s experience)?
This answer supports morning:
I prefer taking it in the morning. I think it helps set my circadian rhythm.
This answer supports night:
I prefer it at night. I find I sleep better.

I had trouble sleeping when I started Paleo and was taking my D3 at night before bed. Was nervous and couldn’t seem to settle down. No problems since I went to morning, I have them with my fish oil right after breakfast.
By the time you read this there will probably be more evidence.
Thanks to Melissa McEwen.
What’s not mixed is that doses of Vit-D five times the Canadian RDA (sometimes higher) help sleep when properly timed.
I used to take my D3 at bedtime, with the rest of my vitamins and fishoil. I was curious whether I’d notice anything with morning timing of D3, so I changed to morning supplements at first light, and as on that same day, I started yawning around 7:30 pm. I noticed because I don’t normally yawn, except that yawning is an effect I get from my bedtime melatonin supplement. So I suspect the switch to morning D3 aids in the body’s changeover to melatonin production.
I can’t say I notice better sleep, because the dog’s been having a hard time sleeping past 5 am. But I’m sticking with morning D3 timing because it appears to trigger melatonin production with the end of daylight. I take 2000 IU D3 on top of 900 IU in multivitamin and calcium pills.
I’ve always taken my D3 early in the morning. Last fall, I decided to stop eating breakfast because, much like Seth’s experience, my body was waking me up earlier and earlier, usually associated with a growling stomach. Skipping breakfast helped me sleep until 6:30 or 7:00 a.m. on the weekends, which is a significant improvement. Even without breakfast I continued to take my D3 in the morning (8K IU).
Two weeks ago, I tried taking D3 at lunch. I slept through the night but felt as if I hadn’t slept at all when I woke up. It was the worst week of sleep that I can remember. Last week I reversed the experiment, taking D3 in the morning, and my sleep returned to being restful.
I like the idea of nutrient timing especially aligning with the circadian rhythm. Vitamin D in the morning and vitamin C before bed. Anyone else experiment with this combo?
I happen to take Vitamin D3/K2 combo in the morning — and at night, I drink some magnesium. Anyone else try this?
