This product combines three of Solgar's premium quality bonesupport minerals. Calcium is the mineral which is most present in our body and is stored mainly in our bones. It is required for strong and healthy bones, and teeth. Boron supplements are advised especially for those on a restricted diet such as Vegans. Magnesium is considered by experts to be a vital mineral required by every organ within the body. It can be recommended for everything from supporting restfulness and muscle function, to releasing energy from food and so relieving tiredness, as well as aiding towards a balanced mind.
