Lactico: Dairy Tolerance

Start with a dose so small it's boring, then let Lactico raise it only when your gut says yes. Not for milk allergy — we check first, and we'll tell you to stop.

Most people who've given up dairy don't have to.

Lactose intolerance isn't all-or-nothing. Regular, gradually increasing amounts of lactose shift the bacteria in your colon toward fermenting it better, so the same glass of milk causes fewer symptoms over a few weeks. It's called colonic adaptation, and it depends on two things: keeping the steps small, and showing up almost every day.

Lactico is built around exactly those two things.

HOW IT WORKS

1. A safety check, first. Three questions. If you have a cow's-milk protein allergy or galactosemia, Lactico will tell you not to do this at all — those aren't lactose intolerance, and exposure makes them worse, not better.

2. A starting dose that matches you. As little as 30 ml of milk a day if dairy currently wrecks your day. Small enough to be boring, which is the point.

3. Log it in seconds. What you had, how much, and how your gut took it. Had yogurt or kefir instead of milk? Lactico does the lactose conversion for you.

4. The plan adapts — both directions. Three comfortable days and we step you up. One bad day and we ease you back down, automatically. You never have to guess whether today is the day to push.

WHAT MAKES IT DIFFERENT

It says no. A dairy app that sold to everybody would be a dangerous one. Lactico refuses to give a plan to people for whom reintroduction isn't safe, and it stops your ramp outright if you report a symptom that doesn't belong to lactose intolerance — hives, swelling, wheezing, blood in stool — and tells you to get seen.

It's honest about what counts. Aged hard cheese and lactase pills are almost lactose-free. That's exactly why they're easy to tolerate, and exactly why they can't train your gut. Lactico won't count them as a dose and won't step you up for them, so the progress you see is real progress.

Your data never leaves your phone. No account, no sign-up, no health data on our servers. Your dose log lives on your device and nowhere else — we couldn't read it if we wanted to.

WHAT IT WON'T DO

It won't cure lactose intolerance. Nothing will: the enzyme deficiency behind it doesn't reverse. What changes is how much lactose you can handle before symptoms start — and that improvement fades if you stop having dairy regularly. The goal is a comfortable everyday serving that you keep.

IMPORTANT

Lactico offers general wellness guidance. It is not a medical device and does not diagnose, treat, cure or prevent any condition, and it isn't a substitute for advice from a clinician who knows your history. Don't use it if you have a milk allergy or galactosemia. If you have a diagnosed digestive condition, are pregnant, or are unsure for any reason, talk to your doctor first. Stop and seek care if symptoms worsen.

SUBSCRIPTION

Lactico is free to download and includes a 7-day free trial. After the trial an auto-renewing subscription is required; it renews unless cancelled at least 24 hours before the period ends, and you can manage or cancel it any time in your Apple ID account settings.
