What is the best WhatsApp chatbot for supplement stores in Brazil?
The best WhatsApp chatbot for supplement stores in Brazil is the one that answers on the number the store already uses, with the business rules written by you. An AI agent on WhatsApp for a supplement store is an automatic assistant that answers which brands, flavors and sizes the store has registered as available, explains delivery, pickup and payment methods, takes the order and records the customer in the CRM. It does not answer questions about health, dosage or results: those go to a person at the store.

What changes in the shop with an AI agent?
What changes is who answers first: the message no longer waits for you and is answered right away. These are four everyday shop situations before and after the CertuAI agent.
TodayTen messages in a row asking if you have the same whey in another flavor
With CertuAIThe agent lists the flavors you marked as available and moves on to the order
TodayA salesperson explaining dosage over WhatsApp because the customer insisted
With CertuAIThe agent says it does not advise on use and brings in a person at the store to take over
TodayA customer asks about the pre-workout that sold out and nobody writes down who wanted it
With CertuAIThe name stays in the CRM with the product of interest, ready to get the restock notice
TodayDelivery order jotted on paper next to the register
With CertuAIOrder written in the conversation, with flavor, size, address and the payment method chosen
What does a conversation handled by the AI look like?
Example conversation
The shop's AI agent
Customer: Which whey flavors do you have today?
AI agent: The flavors marked as available today are what you registered. Which package size?
Customer: Do you deliver to my neighborhood today?
AI agent: About delivery: what you registered. Send me the address and the payment method and I'll take the order.
Is an AI agent or manual service better for supplement stores?
The agent wins on repeated tasks, and the person keeps winning on anything that takes judgment. With manual service, someone at the shop has to stop what they are doing; with the CertuAI agent, the reply goes out on its own and you step into the conversation whenever you want.
| Aspect | The manual way | With the CertuAI agent |
|---|---|---|
| Flavor and size question at the end of the day | Left on read until the store opens, and the customer buys in the app | Answered right away, with the flavors and sizes you marked as available |
| Customer asking how much to take or whether it can be used with medication | The salesperson answers off the cuff, without being the right person for it | The agent does not advise on dosage or health and passes the conversation to a person at the store |
| Neighborhood delivery order | Agreed by voice message, with the flavor swapped when picking the order | Product, flavor, size and address are written in the conversation |
| Product that sold out and has a restock date | The store promises to notify and forgets | The interest becomes a contact and a task in the CRM, so you can notify when you restock |
| Customer who buys the same tub every month | Depends on them remembering the store when the tub runs out | The history stays in the CRM and automatic follow-up picks the conversation back up |
What does the WhatsApp agent do for supplement stores?
It does the customer service that is yours today. You teach the business once in the Brain, CertuAI's knowledge base, and the agent answers clients your way, with your rules.
Brands, flavors and sizes
Answers what the store registered: which brands it carries, which flavors are marked as available and in what package size.
Order for delivery or pickup
Notes the product, flavor, size, address or pickup time, and the payment method the customer chose among those you accept.
Expiration, seal and origin
Reports what you wrote about batch expiration dates, invoices and who the store buys from, which is the question of anyone wary of counterfeit products.
Health boundary
Dosage, combining with medication, pregnancy, illness and promises of results are not answered. The agent says so and passes the conversation to a person.
What questions do clients send on WhatsApp?
They are always the same, and the agent answers each one on its own. These everyday shop messages no longer depend on you having your phone in hand.
How does the agent start answering at the shop?
In three steps, on the same day. No installation, no code and no changing the number clients already know.
Teach your business
In one conversation, you explain catalog, prices, delivery, warranty, and rules, the way you would to a new employee.
The agent answers
It answers right away, records each order and quote in the included CRM, and contacts again those who went quiet.
How much does an AI agent on WhatsApp cost for supplement stores?
The Start plan costs US$ 75 per month and already includes the WhatsApp agent, your business's Brain, the CRM, automatic follow-up and the AI assistants, which come with every paid plan. Pro costs US$ 120 per month and adds the landing page, the wallet and 10 people on the team instead of 5. No lock-in contract and no setup fee.

Create the agent and connect WhatsApp to see it working in the shop.
Create my agentWhat needs to be ready before turning the agent on in the store?
The agent answers what is written, and nothing beyond that. Have these points defined before you connect WhatsApp.
- The product list by brand, flavor and size, with what is marked as available and who updates that marking
- The exact sentence the agent uses when asked about dosage, medication, pregnancy or illness, and who the conversation goes to
- Delivery neighborhoods, fee, cutoff time for same-day dispatch and how pickup works
- Accepted payment methods and the exchange rule for sealed products
- What the store says about origin: invoice, distributor and minimum shelf life of the batches
Whether the agent may suggest another flavor or brand when the requested item is out of stock, or whether it only records the interest and notifies you.
The most common mistake: Pasting the manufacturer's sales copy into the Brain. That wording promises results, and the agent will repeat the promise under your store's name. Write only what is fact from the label and the shelf, and spell out the health boundary in plain words.
Frequently asked questions from supplement stores
Does the agent recommend which supplement to take or how much to take?
No. It answers about product, flavor, size, availability as you marked it, delivery and payment. It does not answer questions about dosage, health, medication or results: it tells the customer and passes the conversation to a person at the store.
How does it know what the store has?
From what you write and keep updated in the Brain. It does not read the inventory system on its own. If a flavor sold out and you did not remove it from the list, it will still say it is available, so the list needs an owner.
Does it compare two brands for the customer?
It compares only what you registered for each one: package size, flavors and what is marked as available. Saying which is better for the customer's goal is up to the salesperson.
Does it work for a store that sells more at the counter than online?
Yes. The agent handles WhatsApp while the salesperson serves people in the store, and the customer who asked at night gets the answer without waiting for the door to open.
In what other fields does the CertuAI agent work?
In any business that serves customers on WhatsApp, because the Brain is written by you. These fields have a day-to-day closest to yours.
Where can I read more about CertuAI's WhatsApp agent?
These pages explain the same agent from another angle: how it works, price, common questions and comparisons between platforms.
In short
Flavor, size, brand and delivery answered from what the store registered. Health and dosage questions go to a person, and every order stays in the CRM.
