Vital supplement

Posted by iHerb Customer on Jul 23, 2017 | Verified Purchase

A well priced good quality supplement. I consider D3 the most important supplement I take. I compound fractured my ankle when aged 47 and was told I would never run on it again and would require a bone graft from my hip. I researched and soon discovered most people including me were lacking in this vital vitamin. I have since been on 5000iu 6 days a week in winter and 4 days a week in summer. I not only avoided a bone graft but was running again within 18 months. I credit D3 for 75% of this achievement. As you can overdose on this supplement I recommend regular blood tests.
