Nutrients from the Sea

Posted in : on 01-06-2026

Valuable nutrients from the sea can make a real difference for your horse. The ocean is a rich and sustainable source of ingredients such as seaweed and marine plants, increasingly used to support equine health.

Why are marine nutrients an interesting supplement?

Marine nutrients have a unique composition that is less commonly found in plants or other land-based natural supplements. Seaweed and microalgae, for example, are extremely rich in:

  • minerals: magnesium, calcium, potassium, iron and phosphorus
  • vitamins: B vitamins and vitamin C
  • proteins and essential amino acids
  • antioxidants
  • omega-3 fatty acids

This diverse profile makes them a particularly interesting addition to a horse’s diet. They help support multiple body functions at the same time, such as metabolism, immune function, and overall vitality.

Which marine ingredients are important for horses?

Seaweed (kelp)

Seaweed is one of the best-known ingredients in equine nutrition. It grows in different forms and colours (green, red and brown) and is considered an exceptional natural source of minerals.

Seaweed is naturally rich in:

  • minerals and trace elements such as magnesium, calcium, potassium, iron and phosphorus
  • vitamins, especially B vitamins and vitamin C
  • antioxidants and plant compounds such as chlorophyll

For horses, seaweed may help support:

  • a healthy metabolism
  • overall health
  • digestive function
  • a shiny coat and healthy hair quality

Microalgae (spirulina)

Microalgae such as spirulina are microscopic organisms that form the foundation of life in the ocean. They are dried and concentrated to be used as a powerful natural supplement.

Spirulina naturally contains:

  • high-quality proteins with essential amino acids
  • B vitamins, as well as vitamins A, C, E and K
  • minerals such as iron, magnesium, calcium and potassium
  • antioxidants such as phycocyanin and chlorophyll
  • essential fatty acids

For horses, spirulina may help support:

  • vitality and energy levels
  • immune system and natural defences
  • recovery and overall condition

Green-lipped mussel

Green-lipped mussel is a shellfish known for its support of the musculoskeletal system and joints.

It naturally contains:

  • omega-3 fatty acids
  • glucosamine and other glycosaminoglycans
  • specific fatty acids (furan fatty acids)

For horses, it may help support:

  • cartilage and connective tissue
  • joint flexibility
  • the production of synovial fluid for improved mobility

In which supplements are these nutrients found?

In equine nutrition, marine ingredients are often included in targeted supplements designed for specific needs. These natural sources are not only used on their own but also combined in different products.

For example, in Muscle Power, spirulina contributes to supporting muscle development in horses.
You will also find spirulina and seaweed in the Natural Multivitamin, which provides vitamins and minerals to support overall health.
