Boron Health Benefits and Uses
Bone Health. Boron has been shown to increase the absorption of calcium and magnesium, two minerals that are important for bone growth and maintenance. However, no human studies have proven that boron can impact bone density. More research is necessary to confirm that boron has a direct positive impact on bone health.

Occurrence of Aluminum
Occurrence. Aluminium Ores. Aluminium is present in igneous rocks as aluminosilicates in feldspars, feldspathoids, and micas; as clay in the soil formed from these rocks; and as bauxite and iron-rich laterite following further weathering. The primary source of aluminium is bauxite, which is a mixture of hydrated aluminium oxides.
