Careful of adverse effects

Gave me a terrible headache and made me feel hot

Great to combat boron deficiency, which may be similar in commonality to iodine deficiency

The price for this product is higher than I would like to see it in fair trade, as well as many other supplement prices. When I take these I feel much more like a normal human being, so I think I may have been deficient.

Read this before you take this supplement

I began taking this one or two times a day for osteoporosis. I noticed it relieved all of my rheumatoid arthritis and osteoarthritis pain - and I began taking more of it when winter came on. I listened to some people in a support group and a few doctors on YouTube who all said you need at least 120 mg for osteoporosis. I took more although I never got anywhere near 120 mg. I was sitting in my car the other day and a big chunk of my scalp fell into my lap with a lot of hair on it! My hair is three feet long - and now half of it has fallen out - boron can cause alopecia. Then I started having relentless muscle cramps and spasms at night - made my life a living hell. Then nausea, confusion, tingly feelings in my arms and legs, less urination, a lot of diarrhea. I began looking up side effects of everything I am taking - and boron was the culprit for everything!!! Look up Toxicity of Boron and see what is written. It doesn't take very much of this stuff to cause problems. I was trying to stay under 20 mg a day - but got up to 30 mg a few times. My arthritis and osteoporosis are both really really bad - but I would say, there is no need to take more than 3 mg a day of this stuff. You can get quite a bit from food. Do the research before you start taking this like crazy.
