...but the right amount can be very helpful.

That is true of most nutrients and vitamins. Vitamin D is sold in megadose 5000 iU doses, which is above the maximum tolerance level, but you'd be better off with a 1500 iU dose. I believe the RDA is about 600-800 iU.

Sorry - hadn't seen the same link in other posts - but it's still good to know.

As posted in the other thread:

The Vitamin D Council suggests a serum Vitamin D level of 50 ng/ml as ideal, not to exceed 100 ng/ml. The VDC also reports levels greater than 150 ng/ml are toxic, another reason to test before taking supplements willy-nilly. ($58 Walk in Lab)

This amount is considered a joke by many except outdated Food and Nutrition board. I have seen multiple sources suggest around 4000-8000 IU a day, which depends on many factors such as age, weight, etc. For instance: 5,000 IU/day by Vitamin D Council:

In looking at my low-normal level of Vitamin D , my sleep doc recommended 4,000 IU/day

Too much of anything is detrimental to your health. Too high a concentration of water in your body will cause your body to shut down. Good health is about maintaining a proper balance... not too much... but not too little.

I have my vitamin D level checked regularly and my target is 75-80.
I am currently taking 18,500 IU per day and finally got my level up to 74. I won't be reducing my dosage until my blood test indicates that my level is significantly over 80. I do pay attention to many MDs who study nutritional requirements. Some I know personally.

Just as a side note, supplementing more than 10,000 IU a day has not been shown to be safe.

Yeah, I have read that the "optimal" level for adults is at least 60 ng/ml, preferably higher. But of course not TOO high. I was taking 5,000 IU a day back when I first had my level tested in 2013, and it was 22. I've eased off a bit and only take it every now and then, but my level is only at 52 now, so still not really all that great.

Libbylou,
My Vitamin D was low. I supplemented with a liquid Vitamin D and over-corrected. I wasn't concerned, because that means the supplement was effective!

I backed off, then my Vit D levels went too low again. So now I've adjusted to the dose that keeps me in the 80-range. I hope it's ok to mention a specific product http://www.seekinghealth.com/liquid-vit ... drops.html

Good luck...

Also, as a reminder, you want to get your levels checked twice a year, once at the beginning of March, and once at the end of August, being the trough and peak of Vit D3 levels respectively. If you can stay between 50 and 100 at each of those tests, you're doing it right.

Also, too much of anything is bad, moderation is all things is the best way to go.

It really depends on whether your doctor checks your levels as to when you are taking too much. I take a lot of vitamin D because apparently diabetics don't produce enough. Even testing in July, I am chronically low. I'm hoping the new regimen works (at least my eczema is better). It even varies with family members. My bro is in Florida, outside all the time, no diabetes or anything chronic and he barely measures in the normal range without supplementation. My sis, in Mn, is right in the middle range without supplementation.
