They have the most thorough review of Vitamin D research I have seen and are more up to date on it than most physicians.
For example, the Rx dose of 50K is D2, not D3 and there are different blood tests to monitor it than the usual Hydroxy D my (not quite up to date) physician orders.

Regarding getting outside, it’s good for mood and morale to go out in the morning light and appreciate the beauties you can find in your environment. Look for them. They are there. When you discover them, rejoice!

However, even when I did six hours per week of morning workouts in an outdoor pool my Vitamin D dropped to below normal levels. So we need to keep on top of it and ask that Hydroxy D be tested so we can find the right balance according to our bodily needs.

I sincerely believe everyone can find something useful on a regular basis in ConsumerLab.com.
Best regards.
