Thank you, MrsD. That's a great video.
I am currently taking 4,000 IU of Vitamin D3 everyday. I break it up into two doses.....2,000 IU mid-morning and 2,000 IU at bedtime.
I'm thinking about asking my two sons to start taking this, too. They're 22 and 26. Do you think 4,000 IU daily would be too much for them?
Thanks!
