What Manufacturers Really Mean By Natural And Artificial Flavors Like many shoppers, I find food labels confusing. In most circumstances, the implications of âartificialâ and naturalâ are pretty clear.
Hydroxylapatite, also called hydroxyapatite (HA), is a naturally occurring mineral form of calcium apatite with the formula Ca 5 (PO 4) 3 (OH), but is usually written Ca 10 (PO 4) 6 (OH) 2 to denote that the crystal unit cell comprises two entities. Hydroxylapatite is the hydroxyl endmember of the complex apatite group.
While the calcium/phosphorus ratio in hydroxyapatite is 1.7:1, energy-carrying molecules such as ATP (adenosine tri-phosphate) and others increase non-skeletal demand for phosphorus. As such, the optimal dietary calcium/phosphorus ratio is between 1.2:1 and 1.3:1. The chart below lists calcium/phosphorus minima and maxima for various life stages on a dry matter basis1.
