Created by Drs. Rachel & Carly of Kale Blossom — moms and health & wellness experts with 30+ combined years of clinical experience and a trusted community of 350,000+ followers — nook helps you understand what’s really in your home and how it may be affecting your health.
After years of working with families, we kept hearing the same questions again and again:
Is this safe for my kids? What actually matters? Where do I even start?
Most homes contain hidden toxins that impact your health. There are 80,000+ different chemicals in your home products, with many linked to hormone, immune, gut, skin, and respiratory issues.
That’s why we built nook — a simple, science-backed way to scan your home products, see what’s in them, and make smarter choices without the overwhelm.
SCAN → SCORE → SWAP
Scan any product in your home and get a clear Low-Tox Score that helps you understand potential health concerns and find cleaner alternatives.
No ingredient decoding.
No fear tactics.
No pressure to be perfect.
Just practical clarity you can trust.
