CardioFlush side effects and safety: what to know before you start

Safety depends on the exact formula and on you. Here is a calm checklist, and when to speak to a doctor.

Does CardioFlush have side effects?

The brand does not publish a side-effect profile on the pages we reviewed. Fiber supplements can cause bloating, gas or loose stools, and may affect how medicines are absorbed. Check your label and speak to a doctor first if you take medication or have a medical condition.

Possible side effects with these ingredients

  • Bloating, gas, cramps or loose stools, especially with fiber such as konjac.
  • Changes in blood sugar after sugary meals if a formula affects sugar absorption.
  • Allergic reactions in people sensitive to a fruit or plant ingredient.
  • Stomach upset from flavorings or sweeteners in liquids.

These are general possibilities, not confirmed effects of CardioFlush.

Talk to a doctor first if you

  • Are pregnant, nursing or under 18.
  • Take heart, blood pressure, diabetes or blood-thinning medicine.
  • Have swallowing problems, bowel conditions, or kidney or liver conditions.
  • Have surgery or a procedure coming up.

Fiber can slow absorption of some medicines, so ask your pharmacist how far apart to take them. Read our medicines checklist.

A word on dropper hygiene

Keep the dropper clean, do not touch it to your mouth, store the bottle as the label says and stop using it if the liquid changes color or smell. See liquid drops vs capsules.

When to stop and get help

Stop using it and contact a clinician if you notice severe stomach pain, vomiting, rash, swelling, trouble swallowing or anything that worries you. Call your local emergency number for chest pain, severe shortness of breath, fainting or sudden weakness. In the US you can also report problems to the FDA through its safety reporting portal.
