No More Mosquitos

Posted by 5102247090103082160 on Jun 06, 2014

I bought this specifically so I wouldn't get bit by mosquitos. I've been taking it about 3 weeks. So far I have'nt been bit one time. And I've been in some pretty bugged-out areas. I hope it works all summer.

Caution for hypothyroid, low blood sugar and immune dysfunction - B1 is an iodine, magnesium and manganese antagonist

Posted by Health-Is-Wealth on Jan 11, 2014

Vitamin B1 - iodine, magnesium, manganese and copper antagonist (among others) - all in some way essential for thyroid/endocrine health. High doses of B1 can therefore lead to: immune dysfunction, hypothyroidism if iodine intake is inadequate; hypothyroid/low blood sugar if manganese intake is inadequate - especially when combined with higher intakes of other less-obvious iodine/manganese antagonists such as niacin, B6, magnesium, calcium, vit C, boron, etc. Additionally, B1 is an essential cofactor for transketolase - suggest caution for people who take medications that also upregulate transketolase (e.g. asthma steroids), because more B1 may lead to depletion of other co-factors and essential nutrients (e.g. EFA's), creating a nasty catch-22 situation. B1 is also mildly anticholinergic - something to be mindful of, because for some people that can be an issue. High intake of B1 is also likely to cause/contribute to bad armpit BO.
