I've heard not to take vitamin D right before bed because it will kinda keep you up. Maybe the vitamin D as a stimulant is what's gives you the extra dream awareness.

Supplementing any "large" amount of either Vitamin D or Bs really messes with my sleep. It makes it harder to fall asleep and I get crazy dreams (and sometimes hallucinations in bed too)

I checked the ingredients. That is because it contains glycerin. Which is a great and safe supplement to take for anyone with sleeping issues. But will cause very vivid dreams at the start. D3 will not by itself have a huge effect on dreams.

This is such a weird fact that I googled it and sure enough it is widely noted!

my bottle of Nature Made D3 also contains glycerin

Probably common since there is pretty much all upside to supplementing it.

> Glycerin

Do you mean glycine? I've not heard of glycerine having a positive effect on sleep, although glycine is often recommended.

Glycine is an amino, glycerin is a triol.

When I tried to search specifically for "glycerin" and sleep I just get a couple of reddit threads, but no real sources.

That's interesting. I know vitamin D can improve sleep quality in people who are deficient, and sleep quality helps with dream recall -- I wonder if that's the mechanism or it's something else.

A cursory search shows lots of redditors taking Vitamin D (some of them way, way too much btw) and having wild dreams too.

I take 800IU a day and haven't noticed anything on that little.

What is way too much? I take around 4000IU per day. Which just about brings my blood levels into the “green” area in blood testing.

The reddit post was taking 50,000IU a day, which is usually the amount prescribed for someone to take once a week.

Your 4000IU isn't too much. Lots of the brands you see in stores are 5k for daily supplementation.

> Your 4000IU isn't too much.

By what metric? Jeez. People, you need to get your blood checked. There is no one-fits-all dosage. In winter, 4000 IU/d was enough to raise my blood levels well into the excessive range.

My 4000 units were after blood testing and also after genetic testing which showed some VDR mutations that might benefit from supplementation. As mentioned in another comment, that dose brings me slightly over 30 ng/ml, so basically borderline ok.

I fully agree that supplementation should always be combined with both blood testing and also a general medical evaluation.

FWIW: my functional provider recently noted low levels in my labs and I was already taking 2K IU daily. She bumped me up to 6K UI daily.

4,000 is perfect.

Current recommendations are 800 IU per day if you’re not significantly deficient. Always keep testing at least once a year or so. I took 5000 IU per day for a while, which ended up pushing me over 60 ng/ml. That’s considered too high a level and may have negative health effects.

I tested after taking 4000 IU daily for quite a while and ended up at 30.9 ng/ml, so I guess I have some buffer left. But I fully agree, regular testing is prudent when supplementing anything above common established levels.

Given 10min of sunlight the body can naturally produce 15,000UI equivalent so I think gp is likely astroturfing for that brand

That is actually a low dose.

Yeah, I showed a really mild deficiency in my work so they just suggested adding a low daily dose for me. I wouldn't expect to have had any side effects.

I was very deficient and they gave me 50k UI per day prescription vitamin D3 for 60 days. Sure enough I was high-normal on my next test. 800ui is likely not enough to have any effect unless you consistently take it for years.

That's wild. I've never heard of such a high dose being prescribed daily.

Yes, I wouldn't expect to notice anything on my dose.

It was for 60 days. If they continued to take this much indefinitely it would surely cause troubles, but 60 days when starting from deep deficiency is reasonable.

I was very very low, googling my level 'risk of rickets' came up!

Even that sounds extreme. The "Vitamin D Hammer" for people extremely deficient is 50k IU just once, not even for a temporary period.

It is high, but it's not extreme. 50k IU just once is an equivalent of about 7000 IU daily for a week, which won't really move the needle much if you're seriously deficient (in fact, it's still within what's considered a safe daily dose for healthy people - you can produce more than that from sunlight alone). You can feel free to take your "hammer" weekly, no deficiency required.

When I took >5000 IU daily for three months, I only raised 25(OH) D level in my blood from 9 to 30 ng/ml, and there's no evidence of toxicity below 150 ng/ml.

Of course, when dealing with high doses you need to keep your levels in check, as absorption can differ between individuals.

Spicy food and dehydration do wonders for me!

You started off writing this yourself and then "augmented" the reply of an LLM for the later part, right? Because the tone of your post changes from human to LLM as I continue reading it.

Yeah it’s pretty clearly a bot account, or at least someone who likes to copy paste from chatgpt to sound smart.

or it might be changing from anecdotal human to technical research human. Here's my question - if you had read that 5 years ago would you think it was written by a human who had done some reading on the matter, or would you think they googled it and copied some of what they found.

Obviously 5 years ago we couldn't have worried it was an LLM, but if you wouldn't have thought someone just copy pasted something without understanding it, or someone was crazy on drugs when they wrote something, then it seems somewhat unfair to give people this new accusation.

This fellow human speaks the truth. You people did trust strangers before the invasion of "Earth", it's totally not fair to be overly wary of the Mimics now!

over-wariness of mimics is just a good way to cut down on the available supply of sexual partners in my book!

You clearly never had sex with a Mimic.

I did too, I met a great Mimic one time on a business trip in Canada, and formed a strong long lasting relationship based on trust, honesty and hot nasty banging.

Had the exact same feeling. The conclusion shifts back to the human.

It contains glycerin which is 100% the cause of the vivid dreams.

I bought some and have not noticed any impact on my dreams.
