Give Vitamin D3 an Upvote! I also use this Supplement and Give it to my Children. I've also tried to get a healthy amount of Sunshine which helps to Metabolize this Vitamin. So take a dose of D3 and go for a walk outside while it's still summer. Here in the North, we only get so much available Sunshine Strength per year that will be strong enough to provide us with our Daily Dose of Vitamin D we need. So I try to get out as much as possible.
