Founder & CEO, RENN Asia Wellness

My work brings together nutritional and functional medicine. Here, I make room for the questions that need a longer conversation: what the evidence says, what it leaves uncertain, and what that means for a person making a decision.

Where should I begin?

Start with the introduction to nutritional and functional medicine, or choose an essay about a question you already have. Reading times are shown beside each essay.

Can I receive the monthly letter?

The monthly letter is planned. Newsletter setup is being considered separately; delivery setup will be completed separately.

The monthly letter

Once a month, when an essay is ready, I write to the people who want to be told. No noise, no selling — only the work.

Newsletter delivery is still being set up.
