A shopper picks up a tub of creatine, turns it over, and asks you three things at once: is it a steroid, will it hurt my kidneys, and why is the gummy version twice the price? Creatine is one of the most asked about supplements on the shelf, and one of the few with strong research behind it. Knowing what the studies say, and how to say it without overpromising, is what earns that shopper's trust.
Creatine: What Works and Why is a free creatine course for supplement store staff. It covers how muscle uses creatine, which form and amounts the research backs, who buys it now, the five myths you will hear, and a thirty-second way to answer questions within the rules. It takes about 30 minutes, self-paced, across seven short narrated lessons, and every lesson lists its sources.
What you'll learn
Seven lessons that go from the science to the conversation in the aisle.
Welcome (Lesson 1). Why creatine is the jar shoppers ask about, how much research stands behind it, and where your job as store staff starts and stops.
How muscle uses creatine (Lesson 2). Where creatine comes from, how it recharges the energy muscles spend in short, hard efforts, and why people who eat little or no meat often respond more.
Forms, amounts and formats (Lesson 3). Why monohydrate is the form behind almost all of the research, the amounts studies use, why creatine is sold as a powder, and how to read a supplement label and spot a third-party testing seal.
Who buys creatine now (Lesson 4). Today's creatine shopper, and what the research shows for older adults and for women.
The five creatine myths (Lesson 5). Steroids, kidneys, hair loss, water weight and cramps: one clear fact and its source for each.
The conversation on the floor (Lesson 6). A thirty-second answer that stays within structure and function claims, and the health questions that go to a pharmacist or doctor.
Put it all together (Lesson 7). One shopper from start to finish in a practice conversation where your choices shape the visit.
How the course works
Each lesson is a short narrated walkthrough with photos, flip cards and quick checks. You read a sample supplement label by tapping each part of it, sort what is and isn't your job on the floor, answer shopper moments as they happen, and build a thirty-second answer in the right order. The last lesson is a practice conversation with a shopper that scores each choice and shows what you did well and what to work on.
It closes with a 15-question final quiz. Twelve correct passes. It works on a phone, tablet, or desktop.
Who this is for
Staff and managers at supplement shops, nutrition and health food stores, grocery and pharmacy wellness aisles, and gyms that sell supplements. Anyone who gets asked about creatine and wants to answer with facts.
What you walk away with
You'll know what creatine does and who it helps most, which form and amounts the research supports, how to answer the five common myths, what you can and can't say about a supplement, and when to send a shopper to a pharmacist or doctor.
Free to enroll. Self-paced. Certificate on completion.

How we checked the facts
Claims were checked against published research, including the International Society of Sports Nutrition's review of creatine safety, and current ConsumerLab product reviews. What staff can say was checked against FDA rules for supplement claims. Every lesson lists its sources, and every photo was checked by eye to make sure it shows what the lesson says.
Training, not medical advice
This course is general education for store staff. It is not medical or nutrition advice, and it teaches staff to send health questions to a pharmacist or doctor. Research changes, so follow your store's procedures and the product's label.
