How to Sell Supplements in Your Gym: Run the Front Desk Like a Shop

A fridge of drinks, a box of bars, a few tubs of protein and a stack of branded tees. Bought on feel, priced off the supplier’s RRP, counted when someone remembers. Is that shelf making money or quietly losing it? Without a count and a margin, there’s no way to know.

It’s fixable without selling harder. Gyms that make retail pay run the counter like a small shop: a deliberate range, a known margin, a count checked against the till, and staff who advise rather than push. Learning how to sell supplements in your gym is the entry point, since that’s where Australian rules bite hardest, but the system covers drinks, bars and apparel too.

This guide covers range, compliance, pricing, the counter, staff, stocktakes and reordering. For the bigger picture, see other ways to lift revenue without touching membership prices. This one is about running the shop.

Key Takeaways

• Stock what members already buy. Ask PTs and log front-desk requests before ordering, then let sales grow the range.
• Check what a product is before it hits the shelf. In Australia a sports supplement is either a food or a therapeutic good, and tablets or capsules making performance claims need to be on the ARTG.
• Price for margin, and remember GST is inside the shelf price. Whey protein powder and capsule supplements are taxable, so calculate margin on the ex-GST figure.
• Staff advise, they don’t push. What your team says at the counter counts under Australian Consumer Law, so give them true words and no reason to oversell.
• Count the shelf against the till. Shrinkage is the gap between your records and the shelf, and it isn’t always theft: unlogged comps and short deliveries land there too.
• Reorder on a rule, not a feeling. A reorder point per product stops both empty fridges and expired stock.

Step 1: Stock What Members Already Buy, Not What the Supplier Suggests

Operators who watch their sales every day still guess wrong. One small UK gym-attached supplement shop expected its coffee machine to earn its keep, and coffee barely moved. A ready-mixed electrolyte drink they had low expectations for became the day-to-day bestseller.

If the people behind the counter misjudge demand, a supplier’s starter pack will too. Build a short starter range from evidence you already have.

Collect that evidence before you order anything:

1. Ask your PTs what their clients already buy elsewhere and bring in their gym bags.
2. Keep a request log at reception for a month. Every “do you sell…?” gets written down.
3. Poll your members. Gym owner Connor Peterson makes the same point about any new revenue layer: ask members directly before committing money, rather than assuming demand is there.

Then map your front-desk shop by category and the job each one does:

• Cold drinks and RTD protein: impulse buys, highest frequency.
• Bars and snacks: impulse buys, low ticket.
• Protein tubs, creatine and pre-workout: planned purchases, higher ticket.
• Apparel and accessories: shakers, straps, towels and tees. Slow sellers, but they never expire.

Start narrow: a handful of lines per category is plenty. One overseas gym-software vendor suggests 5 to 10 core supplement lines to begin with, a sensible starting size, not a benchmark. Add lines when the request log tells you to, not when a rep visits.

If you’d rather not hold shelf stock at all, some supplement makers offer a private-label or subscription model, where members order a gym-branded range delivered through the gym. Treat the revenue-share figures quoted for these arrangements as vendor claims until you’ve seen the contract.

By now you should have a written starter range, with a one-line reason next to every product on it.

If you’re starting from nothing, start with cold drinks and one protein line, then add from the request log.

Step 2: Check What You’re Allowed to Sell Before It Hits the Shelf

A pre-workout sold as powder and the same formula sold in capsules can sit under two different sets of rules. Do you know which one is on your shelf?

The goal: a quick check every new product passes. This is general information, not legal advice, so confirm specifics with your supplier, the TGA, FSANZ or your state food authority.

Food or therapeutic good, never both. Powders, ready-to-drink beverages and bars are generally food under the Food Standards Code. Since 30 November 2023, a tablet, capsule or pill (other than glucose-only tablets) that makes a sports or performance claim is a therapeutic good and must be on the Australian Register of Therapeutic Goods (ARTG) before it can be supplied or advertised. Any form becomes a therapeutic good if it contains a restricted ingredient, such as caffeine at 600mg a day or more, or a substance on the WADA Prohibited List.

Know where your responsibility sits. The Australian sponsor (the importer or manufacturer) handles ARTG entry, not the gym. But you still can’t supply or advertise a product that should be listed and isn’t, and a “not a therapeutic good” disclaimer on the label doesn’t change its status. An AUST L number means the manufacturer self-certified compliance. The TGA audits a sample afterwards and hasn’t pre-approved the product’s efficacy.

Read the label on food-category sports foods. Under Standard 2.9.4, the label should identify the product as a formulated supplementary sports food, say it isn’t a sole source of nutrition, give recommended and maximum daily amounts, and warn that it isn’t suitable for children under 15 or pregnant women.

Protect members who compete. When Sport Integrity Australia and HASTA tested more than 200 supplements that hadn’t been batch tested, about one in three contained a WADA-banned substance (April 2025 survey). Prefer HASTA or Informed Sport batch-tested stock, and point competing members to the free Sport Integrity App to check the batch number. That’s athlete guidance, not a legal duty on the gym. A label that still says “ASADA approved” is out of date: ASADA was replaced by Sport Integrity Australia in 2020.

Check your state before blending shakes. Selling supplements in a gym is one thing; making shakes to order can make you a food business. In NSW, Standard 3.2.2A (from 8 December 2023) can mean a Food Safety Supervisor, with a qualification approved by the NSW Food Authority, plus food handler training for relevant staff. Confirm your category with the Authority. In Victoria, you register or notify your council before trading. Elsewhere, check with your council or state food authority.

By now every product on your shelf has passed this check. The supplier’s paperwork is where the check starts, not where it ends.

Step 3: Price for Margin, Not Off the Supplier’s RRP

The supplier’s RRP feels safe, but it was set to suit the supplier. And if you forget that GST sits inside the shelf price, a slice of every sale was never yours to keep.

Your goal in this step is a known gross margin for every line on the shelf.

Margin isn’t markup. Margin is gross profit divided by the ex-GST selling price. Markup is gross profit divided by cost. Take a protein tub that costs you $45.00 ex GST and sells for $77.00. GST is $7.00, so the net sale is $70.00 and the gross profit is $25.00. That’s a 56% markup but only a 36% margin. Same tub, two very different percentages.

GST sits inside your shelf price. Whey protein powder is a taxable supply, not GST-free (ATO ID 2002/224), and capsule or tablet supplements are taxable too. Don’t assume “it’s food, so no GST”. For drinks, bars and snacks, check the ATO’s GST food guidance rather than guessing. For a GST-registered business, the GST in a taxable shelf price is one eleventh of it. Branded apparel and accessories are ordinary taxable goods.

Show one total price. Under Australian Consumer Law, any total price you show must include GST. If you advertise a component price, such as a shake plus an add-in, the single total price has to be displayed clearly as well (ACCC).

Treat benchmarks with care. Overseas vendor blogs quote 30 to 50% gross margins on supplements. That figure comes with no source, no date and no Australian data behind it. Calculate your own instead.

Give members a ladder. US fitness business consultant Jim Thomas argues a good, better, best line-up works better than a single price point. Put a premium tub beside a value tub and a mid-range tub, and the other two look reasonable by comparison.

Example figures only. Replace with your own supplier costs and shelf prices.

For a GST-free line, the GST column is zero and the net sale equals the shelf price.

By now every line should have a margin, and anything under your floor is repriced or dropped. RRP pricing tells you what the supplier wants. Margin pricing tells you what the shelf actually earns.

Step 4: Set Up the Counter So It Sells Without a Pitch

Before you run a single promotion, move the drinks fridge to where members walk out, sweaty and thirsty.

The goal is a counter where the right products are visible at the right moment and paying takes seconds.

• Put impulse lines at the exit and the point of payment. Cold drinks, RTD protein and bars belong where members pass on the way out.
• Put planned purchases where members wait or chat. Tubs and apparel sell to people who have time to look.
• Keep shelves full and faced. A half-empty shelf looks abandoned, and nobody buys from an abandoned shelf.
• Show a clear price on every line, using the total-price rule from Step 3.

Then make paying frictionless. Take card and phone payments, and let members charge a purchase to their account so nobody walks away because their wallet is in a locker. That helps twice over: you lose fewer sales, and every sale is tied to a member record, which gives you cleaner numbers when you count stock in Step 6.

Unstaffed hours need their own rules. A vending machine, honesty fridge or self-checkout extends selling into 24/7 hours, but it’s also where stock can go missing without anyone noticing. Keep the unattended range to low-value, fast-moving lines. Make self-checkout the only way to pay, keep a camera on the fridge, and count those lines more often than the rest.

One 24/7 gym owner who films his day on YouTube shows a simple version: each morning he photographs the drinks fridge, then checks the count against his POS and self-checkout log before restocking. Any gap shows up the same day, while the camera footage is still easy to find.

By now every product should have a place, a visible price and a fast way to pay, staffed or not.

Best for: 24/7 clubs with a drinks fridge. Skip if: you can’t check an honesty fridge every day.

Step 5: Train Staff to Advise, Not Push

Ask trainers how they feel about supplement targets and you’ll hear a familiar story. In one Reddit thread, trainers and front-desk staff at a big-box gym describe being handed a dollar target for supplement sales tied to their pay. The pressure, they said, cut against the thing that makes them worth training with: being a coach members trust.

The goal of this step is staff who answer product questions honestly and confidently, and incentives that don’t work against them.

What staff say is your legal responsibility. Under Australian Consumer Law, claims about a product’s benefits must be accurate and based on reasonable grounds, and that includes what staff say out loud at the counter. The business is liable even if nobody meant to mislead (ACCC). A staff member promising a product “will strip fat” is a problem. Describing what’s on the label isn’t.

Give them words. A short say and don’t-say list removes the guesswork:

• Say: what’s on the label, honest personal experience, and “I don’t rate that one” when it’s true.
• Don’t say: anything that promises a result or diagnoses a problem.
• Refer on: medical or health-condition questions go to a GP or an accredited practising dietitian.

Borrow what trainers say works. The same thread is full of tactics staff used to stay honest under pressure:

• Recommend softly, and mainly when asked.
• Offer a discount only when a member asks for one.
• Lean on qualifications as credibility, not as a sales line.
• Be straight about products they wouldn’t buy themselves, even if it costs a sale.

Rethink the incentive. Our view: individual dollar quotas on trainers push directly against trust. If you want to sell supplements in your gym without burning that trust, use a team-level incentive, or none at all with retail framed as member service. Members can tell when they’re being sold to, and your PTs know it.

By now every staff member should be able to explain your top five products in one true sentence each.

Honest advice keeps members buying from you over a year in a way that pressure never does over a month.

Step 6: Count the Shelf Against the Till to Find the Leak

Your records say 24 cans should be in the fridge. You count 21. Where did the other three go? Often not where you think.

The goal of this step is a counting routine and a reconciliation sheet that turn “I think stuff goes missing” into a number and a cause.

Shrinkage, defined plainly. Retail shrinkage is the difference between book stock and counted stock. Book stock is your opening count, plus deliveries, minus recorded sales and write-offs. The gap comes from three places:

• Damage and expiry: stock that was binned without being written off.
• Theft: by members, visitors or staff.
• Everything else: a staff member taking a drink without ringing it up, sales not put through the till, short deliveries, and stock moved without being recorded.

That third group is easy to mistake for theft. The 24/7 owner from Step 4 had every drink accounted for except one. He went back through the camera footage and found a staff member had moved stock without logging it. No theft involved, just an unrecorded movement.

Fix the admin first. Before you suspect anyone, close the gaps that create false losses:

1. Every staff drink or comp goes through the till, at zero or at cost.
2. Every delivery is checked against the invoice on arrival.
3. Damaged and expired stock is written off in the system, not just binned.

Set a cadence. Count fast, high-value and unattended lines weekly and the full range monthly. Use the same person, the same time and the same order each count, so differences come from the stock and not the method.

Measure your own rate. Shrinkage % is variance at cost divided by cost of goods sold for the same period. We couldn’t find a reliable published Australian shrinkage benchmark for gym retail, so your own trend over three or four counts is the number that matters.

Example figures only. Replace with your own counts.

Expected on hand = Opening count + Received, minus Sold, minus Comps and write-offs.

By now you should have your first reconciled count and a variance figure you can track month to month. If the variance is concentrated in one line, watch that line before you blame anyone.

Step 7: Reorder on a Rule, Not a Gut Feel

One number per product, worked out once, ends both the empty fridge and the expired tub at the back of the shelf.

The goal of this step is a reorder point for every product and a monthly range review.

The rule: reorder point = average units sold per week × supplier lead time in weeks + a small safety stock. Say you sell 8 protein bars a week, your supplier takes 2 weeks to deliver, and you keep 4 as a buffer. Your reorder point is 20. When the count drops to 20, you order (example figures).

Size stock cover for a small gym. Published advice gives two numbers for two different jobs. One gym resource library suggests holding 30 to 45 days of stock per product, and a US distributor suggests reordering often and dropping underperformers after 60 to 90 days. Neither cites a source. For a single-site gym, hold less cover on short-dated lines (drinks, bars, RTD protein) and more on long-life lines (apparel, shakers, sealed tubs). Cut any line that doesn’t earn its space over a few months of counts.

Rotate by best-before. Move the oldest stock to the front (first in, first out). Flag anything nearing its date for a member special rather than a write-off.

Review the range monthly. Look at sales per product, margin from Step 3 and variance from Step 6. Then keep, reprice or cut.

Example figures only. Replace with your own sales and supplier details.

Every sheet in this article gets easier when the sales numbers fill themselves in. A point of sale linked to your member records logs each sale, each member-account charge and each stock movement as it happens, so your counts, reorder points and monthly review run on real data rather than memory.

By now your reorder points are set and your first monthly review is booked. The shop now runs on numbers, not guesswork.

FAQ

Do I need to register supplements with the TGA before my gym can sell them?

Usually no. ARTG entry is the job of the Australian sponsor, meaning the importer or manufacturer. But you can’t supply or advertise a product that should be on the ARTG and isn’t. Check tablet, capsule or pill products that make performance claims, and anything containing restricted ingredients, with your supplier before stocking them. See Step 2 above for the full pre-shelf check.

Is protein powder GST-free in Australia?

No. Whey protein powder is a taxable supply under ATO ID 2002/224, even though many basic foods are GST-free, and capsule and tablet supplements are taxable too. Price these lines with GST included and calculate your margin on the ex-GST figure: for a GST-registered business, the GST is one eleventh of the shelf price. Check drinks, bars and snacks against the ATO’s GST food guidance. Step 3 walks through the calculation.

Do I need a food safety supervisor to make protein shakes at the counter?

Possibly, depending on your state and how your business is classified. In NSW, Standard 3.2.2A can require a certified Food Safety Supervisor and food handler training, so confirm your category with the NSW Food Authority. In Victoria, you must register or notify your council before trading. Elsewhere, check with your council or state food authority. Selling sealed drinks is a different question from blending shakes to order, so say which you’re doing when you ask.

Is my gym responsible if staff make claims about a supplement?

Yes. Under Australian Consumer Law, the business is liable for misleading claims staff make verbally at the counter, not just in ads or on packaging, whether or not anyone intended to mislead. Train staff to describe what’s on the label and share honest experience, and never to promise results or diagnose. Step 5 includes a simple say and don’t-say list.

How often should a gym do a stocktake?

Count fast, high-value and unattended lines weekly and the full range monthly, reconciling each count against your POS sales. We couldn’t find a reliable published Australian shrinkage benchmark for gyms, so track your own variance over time rather than comparing against someone else’s number. Step 6 has a copyable reconciliation sheet to get you started.
