Vit-D3 supplement effects, and any downsides to vitamin D supplementation?

Answered on August 19, 2014
Created January 24, 2012 at 6:08 PM

I recently started taking 5000 IU vit D3 because winter is always a hard time for me and I thought that if I took it for long enough it might help my winter blues. I wasn't really actively expecting results. I began feeling much better, but I didn't tie it to the vit D3 because there can be so many other factors involved. Then at the end last week I went into a pretty low mood, it was awful but not unusual I guess. I then realised that I hadn't taken the supplements that week. Began taking again, and today I am feeling very good and positive. Of course I can't say it's definetely the vit-D3, but is it possible that it can have such an immediate effect? I thought that if it was going to have an effect, it would show up in the long term.

My second question is, is it safe to take this much vit D3 daily (during the winter at least)? Should I take it only on non-sunny days or when I barely see the outside, or every day? Are there any downsides or potential dangers to supplementing with vit D3? Are there any other vitamins/minerals I should watch out for, in terms of balance with vit D3?

+1 for getting tested, the most common test is called 25(OH)D, which is the one Dragonfly is referring to above. & you will probably need to tweak your dosage as time goes by. This post is interesting & talks about some anecdotal long term D3 use http://www.trackyourplaque.com/blog/2011/01/topping-up-your-vitamin-d-tank.html "Topping up your vitamin D tank"

It's not a "normal" value. They usually do a CBC…which wouldn't include things like thyroid, B-12, Vit D. You can just have that single value checked at any lab and consult with your Dr.

I had this anti-blues effect in the first month of supplementing with D. I take 8,000 IUs year-round, with no issues (except all my asthma is gone as well as eczema...) Best to get tested!

I think you have to have it tested specifically. They don't usually check vitamin D levels in my experience. But your mileage may vary depending on your provider. Check with them on it or check your medical records (you have a copy right? :) ).

Do "check ups" check vit D? I had a "full check up" last summer - blood, urine, ultrasound, stress tests, etc. They didn't say anything so I guess vit D levels are fine? Or is it not a common thing to check? I know B12 was checked, or is that more common to check?

I take 10,000-12,000IU of D3 daily, and it's definitely a good idea to do so for mental health if nothing else. If you're looking for downsides, I read recently about a study linking long term D3 supplementation and calcification of the tissues of the arteries and heart, but keep in mind that other studies have shown that D3 supplementation reduces the risk of heart disease in general. Getting enough K2 acts as an antagonist to D3 leaching calcium into the blood, so make sure you compensate with K2 supplementation if you are worried about this. (I've noticed a boost to my immune system from supplementing both D3 and K2, as well)

Best to get tested! Aim for a blood level of 50-80 ng/ml.

I take 5000 IU of vitamin D every day as well and have for about a year now. I haven't noticed any problems...only benefits. I notice a difference when I miss a few days... especially in the winter.

You can actually have your Vit D levels checked, which I would do if I were you. They say most people are deficient. I take 10,000 IUs a day with no ill effects (and i live in CA where we have more sun year round but I wear sunscreen) and definitely notice a downturn in mood if I forget to take it. The liquid or sublingual is best for absorption. Take it every day and if you are concerned it's too much or too little have it checked periodically.

Here is even more info from Chris Masterjohn on Vitamin D toxicity. It appears to be much safer for you if you take vitamin D in conjunction with vitamin A and vitamin K.

Vitamine D3 is a steroid hormone. if you want to take steroids go ahead and do it.http://www.vivo.colostate.edu/hbooks/pathphys/endocrine/otherendo/vitamind.html i would not.
