Apparently just about everyone that isn't taking suppliments is Vit. D deficient according to the established standards.  But I've yet to see a kid with rickets.  I heard a Doc last week talking about how it's likely that the base line for Vit. d may have been in error all these years.

So now that the sun is starting to shine again, and we will be spending more time outside - are you still going to continue taking your Vit D supplement?

Came across a brief article on Berkley Health that helps to explain why it's important to exercise caution when supplementing your vitamin intake.

The exact same statements made in this article that are attributed to Vitamin D can also apply for virtually any other supplement.

I added Vit D3 about 2 years ago. The dose is 2000 IU twice a day. It is inexpensive and works great for me as it appears to stimulate/support my immune system. I don't feel much different and really didn't expect to. The difference is that I no longer get sick. Don't recall the last time I had the flu or a cold

There is a lot of variability in the quality and safety of supplements. Consumer Lab is a good resource for anyone who uses these products. It requires a membership but provides lots of good research-backed information.

You can not get enough Vitamin D just by 'spending more time outside', that's the problem. Unless you are shirtless and in the sun for an extended period of time on a regular basis you are not going to raise levels enough to be in the 45+ng/ml zone. Low Vitamin D levels are just as prevalent in 'sunny' climes. I lived in LA for 8 years, the last few of which I spent a good amount of time outside every other day and my levels were still deficient enough for the doctor to give me his oh-by-the-way side comment.

I can't even begin to imagine how low it was when I was in Minnesota before that.

And people need to remember it's not about 'I don't notice anything.' This is a crucial hormone your body produces we are talking about. It's like saying I never change the oil in my car and it seems to be running just fine......until it doesn't.

This is about prevention and the research is simply too strong to ignore on Vit. D's role in cancer/cardiocascular/cognition related illnesses. It's a Big F'in Deal.
