Without going into details, I seem to having a lower GI issue with Hair Vitamins. I have recently started taking a few different supplement in past month. Doctor put me on fish oil and red rice yeast. Then I started Hair Vits. After about a week I began having problems.I stopped them all and was fine for a few days. Today I resumed just one of hair vitamins only and the problem returned after about an hour. Just wondering if anyone has experienced this. My plan is to not take them for a week, and resume the fish oil and red yeast ones, since my doctor will be checking my labs again soon. I really want to stay on hair vits so am hoping it is not the cause , or something others have experienced and maybe issue resolves after a while. I do,take with food. I was actually taking a cheaper brand of these hair vitamins w/o problem, but maybe it takes a while for the side effect to occur. Thank you for any help, and know I can call the company also, but like to check with others first. Susi.
