When NASA noticed astronauts were losing essential minerals in space, they started prescribing hydroxyapatite supplementation. A Japanese company picked up on this, and in the 1970s released a commercial toothpaste containing hydroxyapatite. Recently, a toothpaste brand in the USA has also jumped on the bandwagon, and today Dr. B answers two questions about why this is a great prospect! Tune in to hear how hydroxyapatite works on teeth (and bones), why it’s better than fluoride, and where you can find it. Dr. B breaks down complicated chemistry into a simple explanation that makes the benefits of hydroxyapatite clear. From whether nano- or micro-particles are better, to how the state of the mouth affects its efficacy, you don’t want to miss out on this educational episode! Join us today to get the details on two of Dr. B's favorite studies, why you shouldn't be concerned about absorbing hydroxyapatite, and so much more!

Key Points From This Episode:
