When do you take vitamin D supplements?

Answered on August 19, 2014
Created January 02, 2011 at 2:20 PM

Does it matter how or when? Empty stomach? With food? Before food? After food? Early morning? Evening?

The only thing I heard is that it is useful to take it with some fat.

D3 sufficiency increases calcium absorption in general. They don't need to be taken at the same time.

Does the fatty meal matter if you're taking it in an oil-suspension? I thought that was why it was produced that way?

Carlson drops should be taken under the tongue where there are major blood vessels. This should theoretically increase absorption.

Aisssh, just took some vitamin d and it's 7 PM. Well, let's see how I fare. Good thing, I've got some good books to read.

thanks, I knew about the fat, but not about the effect on sleep.

That is interesting - it was my nutritionist who suggested taking the two at alternate times. I specifically asked because I know from studying mineral formation (I'm a geologist), chemistry (they're in the same A-column on the periodic table), etc. that the two ions are highly interchangeable in molecular substances, so presumably just as much so in our bodies. I know a lot less about human physiology, though.

This is interesting. I take a supplement from Douglas Labs called Cal/Mag 1001 recommended by a nutritionist that combines Calcium and Magnesium. It also includes Vit D-3.

I learned not to take my vitamin D before bed the hard way. It makes perfect sense if you think about it - taking the "sunshine vitamin" just before bedtime can mess with your sleep!

Good question! I am curious about the answer, as I take Carlson's D Drops. I just lick 3 drops (6,000 IU) off of the back of my hand after brushing my teeth---on an empty stomach since I usually skip breakfast. During the summer months I usually only take 1 drop (2,000 IU).

You should take Vitamin D after a fatty meal. It is fat soluble. It can also disrupt sleep in some people. Fathead videos with Dr. Cannell

Something to consider if you're trying to get more magnesium into your diet is that Mg and Ca ions can compete with each other. This means if you're taking the Vitamin D with calcium, you might want to do that early in the day, and whatever you're eating or taking for Mg later in the day.

Take them after a fatty meal as everyone has said. It makes more sense to take it during the morning or during the day when our bodies would normally be preforming vitamin D synthesis. No science on that though just some intuition.

I wouldn't be surprised to find out down the road that it doesn't matter whether it's taken with or without fat as long as the diet contains a significant amount of quality fat. The need to take vitamin D with food might also depend on whether you use drops or take pills.

I take it with a fatty meal (don't really have non-fatty meals ever, truth be told) in the morning, but I didn't really notice it affecting sleep when I took it at night. I make sure to eat the 100% dark chocolate and white tea in the morning as well. I think the D3 itself doesn't necessarily affect sleep, but it does have some effect on melatonin production in general, but I think that's just a restoration of the correct level as a whole.

funny to see everyone say that it keeps them awake, cause I just started taking it, and one pill makes me drowsy, 2 will knock me out cold. I am also a natural night owl and prefer to sleep during the day, so I wonder if that has anything to do with it.

In the morning. 4000i.u. I take it when I get up.

Sometimes I have something fatty with it, but the drops I have already have MCT oil in them. It isn't much, but probably enough to get stuff done.

Seth Roberts has been suggesting vitamin D3 in the morning for awhile, and many report improved sleep because of it.

i've read that you should take it in the morning because we wouldn't naturally get vitamin d at night- due to the sun going down. also take it with fatty foods since it is a fat soluble vitamin.

I take 5000 IU per day because I'm following a naturopathic protocol for Lyme Disease. I also supplement with a high quality toxin-free fish oil, flax oil, and other healthy oils. My naturopath told me to always take one digestive enzyme capsule with my oils at mealtime. . .

I take mine when I remember, and because I don't remember every day, I take more if it's been a couple of days. I also blitz it in the fall trying to build up stocks for the winter. I swear that it's what's been keeping this schoolteacher healthy among the teenager germs over the past few winters.

I always take my vitamins right after the meals. But after reading this I won't take vitamin d in the evening anymore. Thanks for these recommendations folks.

I made the mistake of taking vit. D (4000 I.U.) late in the day and it did affect my sleep.

I always take it with a fatty meal, and never before bed or else I won't be able to fall asleep.
