Who We Are

Happy Vitals provides families with the tools they need to monitor and improve the long-term health of their children. With our simple and easy-to-use tests, mothers can learn for the first time about the nutrient make-up of their breast milk, improve their diet and nutrition, and safeguard against exposure to heavy metals and other toxins that are harmful to a child's growth and development.



Our mission is to help families optimize children's health, and to accelerate our understanding of children's health for future generations.
