049: NASA's Dental Care Secret: Saving Teeth with Eco-Friendly Space-Age Tech with Belinda Lau

“I had to find that niche, that core community of people who were trying to solve the same problems that I was and who were passionate about the solution. But if I hadn’t found that, I think it would be tough to try to keep promoting your product and your brand without actually knowing where it fits.” —Belinda Lau

Every toothpaste tube and toothbrush we've ever used might still be existing somewhere on this planet! Plastic dental care products are silent environmental destroyers, with each toothbrush lingering for about 500 years in landfills and oceans.

Belinda Lau, a biomedical engineer with 15 years in medical device innovation, co-founded Elims with her dentist husband to transform oral care through sustainable, science-backed products. Motivated by the environmental impact of traditional dental care and her background in medical technology, she developed a breakthrough toothpaste using nano-hydroxyapatite that delivers clinical effectiveness while dramatically reducing plastic waste.

Tune in as Justine and Belinda explore NASA's nano hydroxyapatite technology, sustainable oral care packaging, TerraCycle's recycling innovation, clean ingredient alternatives to fluoride, bootstrapping a CPG business, growing business as a couple, flavor development strategies, dental professional insights, plus much more.
