I read this topic on here about 3 months ago and decided to give it a try. In the last few years my wrists and certain finger joints began to ache 24/7. I'm in my early 50's and always have been very fit, active, and health conscious and know my body very well. I also have suffered from osteoarthritis in my lower back for decades due to injury.
I started with 1/4 teaspoon of borax in my morning shake after workout. Drank my normal 2 litres of water by lunch and then added another 1/4 teaspoon to plain water for my afternoon 1.5 litres.
Within a week my wrists and fingers were about 60-70% better and I could feel something happening in my back and knees. At first there was some different areas of mild discomfort (and this is expected as the calcium deposits break up) and now they are pain free after about 3 months. There are many other positive health effects with boron supplementation as well as antiviral, anti-fungal plus anti-tumour properties. Check it out:
It helps when you're doing strenuous exercise (working out, labor-related jobs, etc)
Just be warned, when you start taking it, you may notice two interesting side effects, both of which should pass in about a week even if you keep taking it.
you may get diarrhea
your urine may turn food-coloring yellow. It's an alarmingly bright color, but don't freak out. Lol
