I always had seasonal disorders around December every year. I started taking larger doses, and most of them disappeared.
I don't need to take vitamin D once I get out in the sun in the spring. 15 minutes of sunshine gives you thousands of units of vitamin D.
When they set daily requirements, they count obvious symptoms, That only tells them the critical levels.
Optimum levels are something else entirely, and I've learned it's at least 10 times more.
