The 28-Day Dairy Challenge

Don't skip your
dairy memories

Understand your own food patterns — without giving up the dairy you love. A calm, evidence-informed approach to noticing what works for you.

Free to start. Not medical advice. Just your patterns.

The science

Evidence-informed. Every claim traces back to a cited source.

Lactase non-persistence is common

About two-thirds of adults worldwide produce much less lactase after childhood. A 2020 review mapped lactase persistence across world populations.

Dairy is a common food trigger in dogs

Among 297 dogs with food-related skin reactions, dairy was the second most common trigger (17%), after beef. A review of the published veterinary evidence.

Self-tracking helps you notice patterns

LactoGo uses your own food and reflection logs to surface patterns — not a medical test. The more you log, the clearer your personal picture becomes.

Pick your path

Three ways in. Same goal: understand your food.
