Review My doctor recommended Vitamin D3, especially in the winter time. I take this product in conjunction with the Cal-Mag-Zinc good combination for me.
Review Life Extension Vitamine D3 is the best way to add to your daily diet, to keep bones stong. Winter time makes it particularly important to take this vitamine.
Review Since taking this supplement for more than a year, I have not had any additional bone loss. It contains D3, which is the best form of the vitamin. I take two with breakfast and two with dinner.
