The goal of this randomized, double-blind, placebo-controlled study is to assess whether the food supplement Endocalyx Pro reduces sodium and water excess in patients with chronic heart failure.
The main questions it aims to answer are:
1. To assess whether the food supplement Endocalyx reduces sodium and water excess in patients with chronic heart failure.
2. To determine the contribution of different potential working mechanisms of Endocalyx in heart failure patients.
3. To evaluate whether the food supplement Endocalyx will improve patient-reported outcomes such as fluid overload symptoms and quality of life.
4. To confirm the previously demonstrated safety of Endocalyx in subjects with chronic heart failure.
Participants will be randomized to Endocalyx Pro or Placebo daily for 8 weeks, and will be followed 12 weeks.
