Tanya's methodology.
In your pocket.

For more than a decade, I've been asking a different question.
Not how do we treat disease?
How do we build biology before disease appears?

Biology By Design™ brings together my methodology, Root Cause Analysis, biology dashboard and protocols, so you can understand your biology, identify your biggest opportunities, and know exactly what to do next.

Tanya Malik Chawla

Founder of Female Healthspan™

“Your biology is not something that happens to you. It's something you design.”

For decades, women's health has focused on treating disease after it appears.
I'm interested in something earlier.
The biology that changes long before diagnosis.

Muscle. Metabolism. Hormones. Bone. Recovery.

The systems that determine how well women age. For Female Healthspan™ through Biology By Design™, I'm building a new framework to measure, understand and improve those systems using biology instead of guesswork.
