Contact the Cardioflush editorial team

This page explains how to reach the independent editorial team behind this Cardioflush guide, and — just as importantly — what we can and cannot help you with. Please read the first section before you write, because it saves everyone time.

We cannot help with orders, shipping or refunds

If your question is about an order you have placed — where it is, changing it, cancelling it, or getting a refund — we cannot assist. We are an independent guide. We do not sell Cardioflush, we do not process payments, and we have no access to any order record whatsoever.

Refunds and order support are handled by the merchant under the 60-day money-back guarantee. Their contact address is on your order confirmation email and on the official product site. Writing to us will only delay you.

How do I request a Cardioflush refund?

A Cardioflush refund is requested from the seller that took your payment, not from this site. The practical route is: find the order confirmation email you received at the time of purchase, use the support address or returns link printed in it, quote your order number and the email address you ordered with, and make the request inside the 60-day money-back window stated on the official store. Keep a copy of what you send. If the confirmation email is gone, the support contact is also published on the official store page you ordered from.

Who handles Cardioflush customer service?

Customer service for orders, shipping, cancellations, subscriptions and refunds is handled by the merchant that processed your payment. This site is an independent editorial guide with no order system, no payment records and no ability to look up, change or cancel an order. Any email address on this page reaches our editorial team only, so writing to us about an order adds delay rather than removing it.

Is there a Cardioflush support email address?

People arrive here searching for a Cardioflush support address, often typed as support [at] cardioflush.com or as the two-word “cardio flush” spelling. We deliberately do not republish it. We are an independent guide with no relationship to the seller, and printing a support address we cannot verify is how people end up emailing a dead mailbox or, worse, an impersonator. The address that is definitely correct is the one printed on your own order confirmation email and on the official store page you bought from — use that, quote your order number, and keep a copy. If you never received a confirmation email, check your spam folder before assuming the order failed, because that is the single most common cause of a “missing” order.

Cardioflush is not stocked by Amazon or Walmart

If you believe you ordered Cardioflush from a marketplace such as Walmart or Amazon, the seller you actually bought from was a third-party reseller, not the manufacturer. That matters for two reasons: the 60-day money-back guarantee applies to orders placed on the official store, and a marketplace order has to be resolved through that marketplace’s own returns process. We have no visibility of either.

What we can help with

• Corrections — if we have an ingredient, a price or a fact wrong, tell us and we will fix it and note the change.
• Research questions — about the studies we cite or how we read them.
• Affiliate relationships — any question about how this site earns.
• Privacy requests — access, correction or deletion under the GDPR or CCPA.
• Press and business enquiries.

How to reach us

We aim to reply within two business days. We do not give medical advice by email — for anything health-related, and especially before combining a botanical supplement with blood-pressure medication or a blood thinner, please speak to a qualified professional.
