Thiamin is a feed supplement for horses used for muscle tension, muscle fatigue, and problems with locking of the patella. Thiamin, also known as vitamin B1, plays a central role in the horse's energy metabolism and metabolic processes and is especially important for the normal function of the nervous system.

Since the nervous system controls muscle activity and coordination, an adequate intake of thiamin can contribute to better muscle relaxation and reduced muscle fatigue. Thiamin is therefore often used for horses that are perceived as tense, nervous, or that easily become muscularly fatigued. It is also a well-used supplement for patellar locking, where the interaction between nerves and muscles is crucial.

Thiamin is a water-soluble vitamin, which means that excess amounts are normally excreted from the body. This makes the supplement safe to use as needed over longer periods.

A deficiency of thiamin can manifest as muscle disorders, reduced energy, fatigue, and decreased appetite. A thiamin deficiency can also affect the production of neurotransmitters such as dopamine, which can have consequences for both movement patterns and behavior.
