It is also needed to convert Vitamin D to its most active form. These key nutrients contribute to bone health thus boron has a very important role to play to ensure that the nutrients are provided correctly. Boron may also benefit joint health. It is also believed that Boron is required for converting oestrogen into its active form - Oestrogen is required for joint health. Because of its ability to activate oestrogen, it is believed that Boron may also aid hormone regulation. Boron is normally obtained through the consumption of fruit and vegetables in our diet.
