Fluoride-containing solutions increased the mobilization and leaching of aluminium from soils. Leaching of aluminium was reported to be greater from soil contaminated from an aluminium smelter than from uncontaminated soil (Haidouti, 1995). In the uncontaminated soil, losses of aluminium from the acid soil were higher than those from the calcareous soil. Arnesen (1998) also found that fluoride can solubilize aluminium, iron and organic material and can increase soil pH through exchange with hydroxide ions.

So basically scientists created a substance in the laboratory that duplicates the end product of what happens when people or animals go outside on a sunny day and their skin synthesizes vitamin D from exposure to sunlight; it's basically a lab made vitamin supplement.
