In November, I wrote about Tara Grant (aka Primal Girl)’s discovery that taking Vitamin D first thing in the morning rather than later improved her sleep. Then several people commented that they had observed something similar — some in response to my post (my post led them to try it), some independently. Perhaps people who tested her observation and found it wasn’t true didn’t comment.
One way to assess this possibility is to ask people who have tried it what happened. In the comments to one of my posts about this, Tyler Tyssedal said he would try it. A few days ago I asked him what had happened. Here’s his reply (shortened):
I have been tweaking the timing of my Vitamin D3 intake since I made that comment [on December 13 -- one month ago]. I have also made a few other life changes (such as supplements), so the changes I’ve experienced cannot be attributed only to Vitamin D3 (5000 IU) timing. But yes, taking D3 first thing in the morning instead of later noticeably improved my sleep quality. I have been experiencing perpetual, involuntary biphasic sleep on and off for years. I would go to bed around 11 and wake up every day between 4 and 6 am, conscious enough to check the time and sigh. I had been taking my D3 with lunch or dinner, sometimes never. I changed my D3 intake to first thing in the morning. Within a week I noticed I would wake up two out of three nights, around 6 (so a little later), a marked improvement.
I am a 6’2″, 160-lb male. I live in Minneapolis, Minnesota. Desk job, lift 2-3 times per week, 45 min-1 hr per session with 15 min walking to and from gym. I typically eat two meals a day (1-2 pm and 6-8 pm). In the morning (between 7:30 and 10am) I consume about 20-30 oz of coffee with 1-3 T cream. I also eat 1 T coconut oil with my coffee and 1 T of it with my dinner.
When I changed my 400 mg magnesium citrate supplement to early afternoon rather than right before bed, I experienced even better sleep. After all these changes, I no longer wake up in the middle of the night. I sleep straight through. A week and a half ago I started taking ALA and NALC with my D3, coconut oil and coffee in the morning. The results have been fantastic and I feel a strong clear headedness in the morning.
Here’s a summary:
WAKE (7:30-9:30am): 5000 IU D3, 500 mg acetyl l-carnitine, 250 mg alpha lipoic acid, 1 T coconut oil, 20-30 oz coffee, 1-3 T cream.
LUNCH (12-2pm): 30% food for the day, typically lowish carb, 400 mg magnesium citrate, 1.2 g EPA/DHA fish oil (on days I don’t consume sardines or salmon, which is 2-3 days a week), Vitamin K2 (1000 K2 MK4, 1000 K2 MK7).
DINNER & POST DINNER: Rest of food (100-150 g carbs post workout workout days; 50-100 g non workout days). On restless nights, 2-5 mg melatonin.
I’ve been pleased with 2-5 mg melatonin before bed on days when I am not heavy eyed by 9:30 pm. I have taken melatonin on and off for years and would still experience biphasic sleep, with or without it.
