Next up boron has been known to help with the painful condition known as arthritis. In the Journal of Nutritional Medicine there was a study involving 20 patients. Half of the patients were given 6 mg a day of boron, while the other group was only given a placebo. The result was that five of the 10 people that took boron experienced positive results, while only 1 person in the placebo group had improved arthritis symptoms.

Next up boron is used by the brain to help people with thinking, solving puzzles and remembering names. According to the United States Department of Agriculture in Grand Forks North Dakota 3 clinical studies confirm that low levels of boron contribute to a lower brain frequency activity. Boron was also shown to improve things such as attention, eye-hand coordination, short and long term memory.
