Nutrients connected to Heart Failure

A link means the body needs the nutrient for this, or that low intake is linked to it. It does not mean extra supplements help if your intake is already adequate; each link shows how strong the evidence is.

• DandelionDocumented risk

  People with heart failure should avoid it because of possible high potassium.

• GoldenrodDocumented risk

  Not recommended where reduced fluid intake is advised, such as severe heart disease.

  Studied as an add-on to usual care in chronic heart failure; a Cochrane review found better exercise capacity and symptoms but no data on deaths, and NCCIH calls the evidence conflicting. NCCIH also describes one study where a preparation may have been linked to earlier progression.

• ArjunaPreliminary or mixed

  A 100-person trial found no gain in ejection fraction; a 2026 meta-analysis found lower left ventricular mass but no clear ejection fraction gain.

  Severe cardiac disease is given as an example of a condition where reduced fluid intake is recommended, a contraindication in the EU monograph.
