I have been taking a Bone Support supplement with Strontium Citrate and many other bone support vitamins and minerals in it for 9 months . There is
10 mg of Manganese in it plus the normal amount you get from food etc. They say the upper limit is 11 mg per day but this is thought to be a conservative level. I am over the 11 mg with food. I know this is a heavy metal and can deposit in the brain in high doses. Is this only from inhaling it (Welders, etc) or enviornmental not supplementation? I have found on this site that many of you are knowledgeable on these matters. What are your thoughts?



Any thoughts on this?
