I WOULD HAVE GIVEN THIS PRODUCT MINUS STARS IF I COULD BUT HAD TO GIVE ONE STAR RELUCTANTLY: THIS PRODUCT CONTAINS ALGAE (KELP). SINCE USING VEXUM.SL I HAVE DEVELOPED A THYROID DISORDER (HYPOTHYROIDISM).THYROID PROBLEMS USUALLY RUN IN FAMILIES BUT NO ONE IN MY FAMILY SUFFERS FROM IT! I HAVE DONE A LOT OF RESEARCH INTO THYROID DISEASE AND RESEARCH SUGGESTS THAT KELP IS RICH IN IODINE AND CAN INTERFERE WITH NORMAL THYROID FUNCTION. BE EXTREMELY CAUTIOUS BEFORE USING THIS PRODUCT!
