Marshmallow root – a natural source of mucilage and soluble fibre as part of the diet of horses and dogs

Marshmallow root (Althaea officinalis), also known as marsh mallow, is a plant whose use in animal feeding is based on its naturally high mucilage content, particularly in the root. Mucilage consists of water-soluble polysaccharides that form a gel-like structure when combined with liquid.

Marshmallow root forms a gel-like structure with liquid that blends evenly into the feed mass. In the digestive tract, this structure travels along with the rest of the feed as part of the overall diet. Mucous membranes are the natural surface layer of the digestive tract, and plants containing soluble fibre are often included as part of a varied and periodic herbal feeding regimen.

Mucilage and soluble fibre as part of the diet

According to the literature, the mucilage content in the root of marshmallow is typically around 15–30 % of the dry matter. In addition, the plant contains soluble dietary fibres such as pectin and beta-glucan.

Soluble fibres bind water and affect the composition of the feed mass. Fibre-rich plants are often included as part of a balanced diet, where the structure and moisture of the feed are considered as part of the overall approach.

Other natural compounds in the plant

Marshmallow root also contains flavonoids and other polyphenolic compounds naturally found in plants. These are part of the plant's natural chemical profile and occur alongside fibres and minerals.

In a plant-based diet, such compounds are part of a varied and balanced whole.

Context of use

Competition seasons, transport and environmental changes are part of daily life for many horses and dogs. In these situations, dietary variety and fibre structure may come under consideration as part of the overall approach, and plants containing soluble fibre are used periodically as part of a varied herbal feeding regimen.

Marshmallow root does not replace a balanced basic diet but complements it as part of a considered approach.

Composition:

Marshmallow root (Althaea officinalis), naturally containing e.g. mucilage (approx. 20–35 %), pectin (approx. 10 %), asparagine (approx. 2 %) and minerals (approx. 5–7 %).

Dosage:

Horses (approx. 500 kg):
1–2 dl per day as part of the diet.

Dogs:
1/2–2 tsp per day as part of the diet.

Measure guide:
1 tbsp ≈ 3 g

Important considerations regarding use

The mucilage contained in marshmallow root may slow the absorption of other substances. If the animal is on medication, it is recommended to consult a veterinarian before use.

Not recommended for horses with a tendency towards low blood sugar.
