I order these about 2 weeks ago. I'm gradually increasing the number of tablets every other day because when I first started taking 8 tablets a day, I felt constipated. Off course drinking more water could help but I personally feel that taking 4 tablets a day is working best for me at the moment. I take 2 in the morning with breakfast and 2 at dinner time. One thing I'm not sure of is that I also drink tea in the morning, and don't know whether it effects the absorption of the nutrients in the tablet or not. Overall I'm happy with my purchase. And I'm also thinking to buy multivitamin for my husband, too.
