Lanthanum is considered a rare earth metal because the process to mine it is difficult, time-consuming and expensive. Lanthanum is rarely the dominant lanthanide found in the rare earth minerals, and in their chemical formulae it is usually preceded by cerium. Rare examples of La-dominant minerals are monazite-(La) and lanthanite-(La).
In the human body,the absolute bioavailability of lanthanum (administered as lanthanum carbonate) wasalso extremely low (0.00127% Â± 0.00080%), with individual values in the range of0.00015% to 0.00224% (Pennick et al. , 2006).
