A client holds up a bottle and asks the question every coach eventually gets: "What should I take?"

It feels like the safest question in the world. Supplements sit on a shelf at the grocery store. No prescription, no pharmacist window, no chart. If anyone can buy it, surely anyone can recommend it.

That instinct is exactly backwards, and understanding why will protect everything you’re building.

Over the counter describes how a product is purchased. It says nothing about who gets to select that product as an intervention for a specific person with a specific health concern.

Those are two different questions. The first one belongs to retail. The second one is where scope lives.

Across the country, a growing number of states regulate individualized nutrition advice under their dietetics and nutrition practice laws. The details vary widely, which titles are protected, which acts require a license, what counts as general education versus individualized care. But the pattern is consistent: in many places, the recommendation itself is the regulated act. Not the bottle. The sentence that pairs the bottle with her condition.

If that sounds theoretical, it has a name and a docket number.

A certified health coach in Florida offered individualized dietary advice through a paid coaching program. The state imposed $500 in fines plus $254.09 in investigatory fees for practicing without a Florida dietitian license. That figure is confirmed in court records, and on its own it sounds almost small.

What came next is the real lesson. She challenged the fine on First Amendment grounds. She lost in federal district court. She lost again at the Eleventh Circuit. She petitioned the U.S. Supreme Court, and in December 2022 the Court declined to take the case. The ruling against her stands.

Read that arc again as a coach. The fine and fees totaled $754. The fight ran for years and went to the doorstep of the Supreme Court, and the answer at every level was the same. The cost of a scope violation is never just the number on the citation. It’s the years, the fines, the fees, the fear, and a public record with your name on it.

And here’s the part I want you to sit with. She wasn’t reckless. By every account she believed she was helping. The line caught her anyway, because believing you’re helping has never been the test.

Here’s the line, and it’s the same line that runs through everything I teach. You can name, describe, and educate freely. You cross it when you claim to treat a condition, direct a medical decision, or promise an outcome.

Applied to supplements, that sorts cleanly.

Reading a label out loud with your client is education. Explaining what magnesium is, and why different forms of the same mineral behave differently, is education. Describing what researchers are studying a nutrient for is education. Helping her build a list of questions for her provider is education, and it might be the most valuable thing you do all week.

Choosing her dose is not education. Naming the brand that will solve her sleep is not education. Pairing a product with her symptom and sliding it across the table is not education, no matter how gently you slide it.

When the two columns blur, one question un-blurs them: Who chose the intervention?

If she came to you already holding the bottle, already curious, and you educated around her choice and routed the decision to her provider, she chose. That’s coaching.

If she said "I can’t sleep" and you reached for a supplement, you chose. You selected an intervention for a health complaint, and there’s a word for that. It isn’t coaching.

One more thing, because it catches the most well-intentioned coaches I know. Saying "talk to your doctor first" is not a permission slip when you were the one who selected the intervention. The disclaimer doesn’t move the choice back across the table. It just puts a bow on it.

You know the six reserved verbs. Diagnose, treat, cure, reverse, correct, heal. In supplement conversations they rarely show up in uniform. "This will heal your gut lining" is a treatment claim in wellness clothes. "It corrects the deficiency" is the same claim in a lab coat.

And watch the two words that hide: fix and manage. "This fixes your cortisol" sounds like encouragement. It’s an outcome promise attached to a product, and licensing boards, the FTC, and the platform algorithms all read it exactly that way. The words that protect your license protect your reach. They’re the same words.

At the bedside, you never chose the supplement either. The provider ordered it. The pharmacist verified it. Your work, and it was skilled, essential work, was giving it safely, watching the response, and teaching the patient around the plan.

The hospital never lent you that claim. The claim was never yours to pack. So nothing about the coaching chair took something from you. What you carried out the door is what was always yours: the assessment eye, the teaching voice, the gift of making a complicated plan make sense to a worried person. That transfers completely.

A client asks about magnesium for sleep. Here’s a scope-safe answer, start to finish.

Magnesium is a mineral involved in hundreds of processes in the body, and sleep researchers have been studying it for years. There are several forms, and they behave differently, which is why two people can have completely different experiences with it. What I can do is help you put together the questions worth bringing to your provider, so the two of you can decide whether it fits your whole picture, especially alongside anything you already take.

Every sentence teaches. Not one sentence selects. And notice what happened to your client. She leaves more capable, not less. She has language, questions, and a plan for the right room.

Education is not the consolation prize you offer because you weren’t allowed to recommend. Education is the actual work.

The scripts in this post cover the moment a client asks you out loud. For everything you write (your posts, your emails, the content that carries your name), run it through the free Three-Question Scope Check first. That's the tool built for sentences on a page. The conversation in the room already has its own test, and you just learned it: who chose the intervention? Keep each tool where it belongs and the line stays visible in both places.

You know more than you’re letting yourself use. Use it inside the line, and it will carry you further than any recommendation ever could.
