About Letters of Radiance.

We aim to use this blog as a way to communicate research and relevant information about the Rosita App and our journey as a startup.

Expect well reasoned and researched posts about the topic of longevity and senior health. We have a strong team of researchers and doctors, including biomechanics, nutrigenetics, molecular biology, cancerous cell research and the fitness science, and together we will build out the Longevity Pyramid with regular posts.

You can use Rosita in US and Spain, by downloading the App here: Rositalongevity.com.
