The carao is for my wife.  Elaine has suffered with anemia issues for most of her life and now (at 64) is borderline with a thyroid condition.  She is 2 thirds through the 2nd bottle of carao and last week received good results from a recent blood test.  Her endocrinologist was impressed with her improvement since the last visit (before she started the carao).  Elaine has also  recently been taking largish doses of vitamin C (a 1,500 mg tablet morning and night) so that may also have a bearing, though going by the text above vitamin C should be taken with vegetables to improve iron uptake (Elaine takes it on a empty stomach ) so it's hard to say what does and does not work.  But she feels that the carao has helped, she has more colour in her hands, before her palm-lines were white whereas now they're pink (and we're in the middle of winter when white palms are not unusual). I hope the above has helped.  Cheers, Peter Australia
