I have taken the product for 2 months with no problem. I eat something adequate before taking the calcium, I take the Growth Factor S on an empty stomach as soon as I get home from work. I am looking forward to my DEXA scan after 6 months on product. I sleep much for deeply & longer as an added benefit. I am quite satisfied with the product & will post my bonescan results in a few more months, THAT will be the true test.
