What this is, and what it isn't.

1. Not medical advice

Nothing Solid Protocol produces — not your protocol, not an Ask Solid answer, not a morning briefing, not a weekly read — is medical advice. It does not diagnose, treat, cure or prevent any disease, and it is not a medical device.

It is a structured way to think about supplements using your own numbers. The decision about what you actually take is yours, and it belongs in a conversation with your doctor or pharmacist.

2. How we word things

You will notice the product says a compound supports something rather than fixes it. That is deliberate, not hedging. Statements describe support for normal, healthy physiological function, and each one is calibrated to how strong the evidence for that compound actually is.

Where the science is still forming, the product says so plainly rather than rounding up to a promise.

3. Your lab values

Solid reads the lab markers you enter and describes each one by its number and its reference range. It does not attach a clinical label to them.

A marker that sits inside its range but below the range's optimal part is described as headroom to optimise — not as a deficiency, and not as a condition. Only your doctor can interpret a lab result as a diagnosis, and only with the rest of your clinical picture in front of them.

4. What the evidence tiers mean

Every compound carries an honest tier so you know how firm the ground under it is. A tier describes the state of the published evidence for that compound in general — it is not a prediction about you.

A high tier is not a guarantee that a compound will do anything for you. Individual response varies, and the "typically felt in ~X" notes are a rough expectation drawn from the literature, never a schedule you are owed.

5. What the scorecard proves

The scorecard compares the days you took a supplement against the days you skipped it, across the signals you log. When a clear, consistent gap shows up, it flags the compound as lining up with your better days.

The product deliberately refuses to speak when it does not have enough to go on: without both on-days and off-days it will say there is not enough variation rather than invent a signal, and it lowers its own confidence on weeks you skip logging.

6. Interactions and combinations

Solid surfaces known interaction and "avoid combining" notes, including with medication, so that you can raise them. It does the opposite of clearing them.

Solid will never tell you that a supplement or a combination is safe for you to take. That is a clinical judgement about your body, your medication and your history, and it is reserved for your doctor or pharmacist. If you ask it directly, it will point you there — that is the intended behaviour, not an evasion.

7. When to talk to your doctor first

Speak to your doctor or pharmacist before starting, changing or combining anything if any of these apply to you:

• you take prescription or over-the-counter medication of any kind
• you have a diagnosed condition, including thyroid, liver, kidney, cardiovascular, autoimmune or psychiatric conditions
• you are pregnant, trying to conceive or breastfeeding
• you have surgery coming up — several common supplements affect bleeding and anaesthesia
• you have a history of an eating disorder or of supplement overuse
• you notice a new or worsening symptom after starting something

Never stop, change or replace prescribed medication on the basis of anything Solid tells you.

8. Who this is not for

Solid Protocol is for healthy adults who want structure around supplements. It is not for anyone under 18, and it is not designed for managing a diagnosed illness. If you are looking for something to treat a condition, this is the wrong tool and we would rather say so than sell it to you.
