Store help

Reviewed on 5 October 2026
On this page
Help page of Lucía Navarro Nutrición's store with the form to write to her.

Here you write to the store without entering your member area. It is useful before buying, to ask about a product, or when you do not remember which email you bought with.

The store answers you by email, at the address you type in the form.

How to get there

In the store, click the help link in the footer. The page is the same in every OnBio store, with the name of each one.

What you can do

  • Write to the store with your Name, your Email, the Subject and the Message.
  • Enter your area with Sign in to my member area, if you already bought and prefer to ask from there.
  • Find out who charged you with Who charged me? if you do not recognise a charge.

Step by step

Send a message

  1. 1. Type your Name and your Email.
  2. 2. Type the Subject and the Message.
  3. 3. Click Send message.

What happens next

You see «We have received your message.» with the name of the store. Its team answers you by email. If you are already a customer, the conversation also appears in My questions of your area with the same email.

Keep in mind

  • We use your email only to reply to you, as the privacy policy linked below the form says.
  • If the store does not have its help available, the page says so with This help page is not available.
  • A refund is handled faster from the purchase than with a message. Enter your area and ask for it from there.
