Thats great when you live in the sunshine! We have approximately 5 hours of daylight. The daylight is cloudy. Unless you want to stand nude in the rain for those five hours, its not highly beneficial.
And the neighbors really start to complain. Wouldn't know why!
Vitamin D also has other important values. If a doctor recommends it, then there is something to it.
We do have problems where I live of getting sunshine any time of year. The downfalls of living in a rainforest! Wouldn't trade it in for anything!
ANd actually my mistake. I believe you may be looking for 2000 IU. Not mg. Check to be sure. I'm sure its IU (International Unit) I'm sorry for the mix-up. Plus, there are different types. If you are not responding to one version, you can try different versions. Gosh, as soon as I have time I'll find something and post it. Its complicated. I already made one mistake with units, I don't want to make another due to my rush to get things done.
