I just had my second bone density test in 4 years and have found my t-score has improved in my spine and neck. I think it is a direct result of taking this product, as I have not really changed much of anything else in my lifestyle. I have not been very good about taking the recommended dosage of this supplement, ( I know I was taking at least one pill and sometimes two per day for the last 6 months.) but now that I see what a difference this supplement can make, I will be more diligent in the future. This is a great product at a reasonable price!
