How ingredients work

Carfol

  • Sweet flag (Acorus calamus) – Contains bitter substances that are traditionally used to support appetite and promote the production of digestive juices.
  • Cardamom (Elettaria cardamomum)– Known for its aromatic properties and is often added to herbal mixtures to support stomach and intestinal function.
  • Fennel (Foeniculum vulgare)– Traditionally used for its essential oil content, which can help eliminate excess gas and promote a relaxed abdominal feeling.

Polyc

  • Flax seed -Rich in mucilages known for their soothing effect on the digestive tract.

MultiDigestiv

  • Lithothamnium -Lithothamnium is a seaweed rich in calcium and magnesium. It helps buffer excess stomach acid and thus maintain a healthy pH level in the stomach. This contributes to comfortable stomach function and smooth digestion.
  • Oyster lime -Oyster lime contains natural calcium, which helps neutralize stomach acid and maintain a strong stomach lining. Suitable for horses that are sensitive to stress or irregular feed intake.
  • Potato protein -Potato protein is easily digestible and supports healthy nutrient absorption. It contributes to a balanced energy balance, especially in horses that eat less or lose weight more quickly.
