A supplement routine,with a reason for every product.

What the routine planner does

Suppin turns your answers into a daily supplement routine: which products to take, at which part of the day (morning, noon, evening or bedtime), how much per take, and a short reason for each one. It is meant for people who already take supplements, or are thinking about it, and want a plan that fits their goals instead of a cupboard of bottles bought one at a time. The routine is educational guidance. It doesn't diagnose anything and isn't a substitute for advice from a doctor or pharmacist.

The questions it asks

You pick up to five goals, such as sleep, energy, stress and mood, focus, immunity, fitness, heart or gut health. A few follow-up questions appear only when they fit your goals: what gets in the way of your sleep, when your energy dips, how often you train. Then come your age range, how you eat, oily fish and sun, and your health answers: pregnancy, breastfeeding or trying to conceive, prescription medication, conditions you manage, allergies and intolerances. Finally, what you already take, the forms you'd rather avoid and whether you use a pill organiser.

• Medication choices include blood thinners, sleeping pills, thyroid, diabetes and blood-pressure medicine and antidepressants
• Allergies include fish, shellfish, soy, milk, gluten, nuts, eggs and sesame
• Forms you can avoid: large tablets or capsules, powders, liquids and gummies

Built by rules, not by AI

Your routine is not written by a language model. A rules engine on our server takes the nutrients with evidence for your goals, removes anything a safety rule blocks for you, and leaves out what the products you already own cover. For each remaining need it picks a product from a catalog of over 17,000 by its quality score and its buyers' ratings, where a rating from many reviewers counts more than one from a few. The same answers always give the same routine. It takes a few seconds, and every product is scheduled at one serving from its label.

Safety rules that come first

Before anything is added, the engine checks your health answers. Products that don't suit pregnancy or breastfeeding, that can interact with a medicine you take, that contain one of your allergens or don't fit your diet are left out. Daily upper limits are checked against everything you take, including the products you already own. Where a combination needs a closer look, the product is marked “Review with a professional” instead of being added. If you skip the health questions, the app doesn't add new products for you; tracking what you already take still works.

Every product comes with its reason

Each item in the routine carries a one-line reason, such as which goal it covers and why it sits in the evening, with the evidence behind it as the detail. “About this routine” sums up the priorities, what was considered from your shelf, what is new and what was left out for size. Timing follows simple rules: fat-soluble vitamins with breakfast, magnesium with dinner, iron apart from calcium. If your goals or your shelf change later, the app suggests a review and you choose whether to rebuild.

You stay in charge

The routine is a starting point, not a prescription. You can add any product yourself and choose its part of the day, the days it repeats and the amount per take, or remove anything you don't want. Products a clinician prescribed are tracked as they are. You can change your answers at any time in Settings and generate a fresh routine, and your previous routine is kept in history.
