Boric acid and other borates are increasingly being used in over-the-counter nutritional supplements as a source of boron. It is thought that boron has a potential therapeutic value in promoting bone and joint health as well as having a limiting effect on arthritis symptoms. It is important to note that the health effects of boric acid and boron-based
supplements are based on very new studies and/or are based solely on the claims of the manufacturers’ of the supplements. It should not be implied that boric acid should be directly ingested as a supplement or for any other reason.
