PSSM Bundle

L-Carnitine is a vitamin-like substance that plays a role in energy metabolism. In equine feeding, it is used as part of nutritional concepts aimed at supporting fat metabolism and muscular function – particularly in horses under increased physical demand.

L-Lysine is an essential amino acid that cannot be produced by the horse’s body. It is required for the formation of protein structures and is included in feeding strategies focused on maintaining muscle condition – especially in growing or physically active horses.

Gamma-oryzanol is a natural compound derived from rice bran oil with antioxidant properties. It is traditionally used in equine nutrition to support ration concepts for physically active or training horses.

L-Threonine is an essential amino acid and a component of many body proteins. In equine feeding, it is used to support the nutritional supply of amino acids in relation to muscle and connective tissue – particularly during growth or physical exertion.

Used in feeding strategies that focus on energy metabolism and muscle-related nutrition, especially in active horses.

Vitamin E is a fat-soluble vitamin with antioxidant properties. It is commonly included in equine nutrition to support the nutritional management of muscle metabolism and to contribute to a balanced micronutrient supply – especially in situations involving physical exertion or training.

DL-Methionine is an essential amino acid that provides sulfur and is involved in various physiological functions – including the formation of keratin and normal energy metabolism. A targeted supply may be considered nutritionally relevant, particularly during periods of increased demand, such as growth or seasonal coat change.

Selenium is an essential trace element involved in multiple metabolic processes in the body. It is included in equine feeding concepts that aim to support cell protection and muscle-related nutrition – particularly during intense physical activity or training phases.

Ashwagandha (Withania somnifera) is a traditionally used plant extract that contains naturally occurring secondary plant compounds. In equine nutrition, ashwagandha is used as a supplementary ingredient in feed formulations aimed at supporting the nutritional balance of the nervous system and overall wellbeing – particularly in older, sensitive, or hormonally challenged horses. A tailored intake may support inner balance during phases of increased demand or environmental change.

Magnesium chloride provides bioavailable magnesium – an essential mineral and key component in the horse’s electrolyte balance. Magnesium is involved in numerous physiological functions, particularly those related to neuromuscular function and energy metabolism. A demand-oriented intake may contribute to the nutritional support of the nervous system, muscles, and recovery – especially in physically demanding situations, during stress, or in regeneration phases.

Serotonin is an endogenous neurotransmitter that plays a role in the central nervous system. In equine feeding, targeted nutrient supply may support the nutritional management of the nervous system and contribute to maintaining inner balance – particularly during phases of tension or following physical exertion.

Vitamin B1 (thiamine) is a water-soluble B-vitamin naturally present in grains, yeasts, and herbs. It is used in equine feeding as part of the nutritional management of energy metabolism and is associated with general physiological functions related to the nervous system and muscles. A balanced supply may be particularly relevant during periods of increased physical demand.

Vitamin B2 (riboflavin) is a water-soluble B-vitamin found in yeast, grains, and green plants. In equine nutrition, it is traditionally used to ensure an adequate intake of this micronutrient as part of a well-balanced ration – particularly in phases of increased demand or in cases where liver function may be limited. It is also associated with nutritional strategies aimed at supporting skin, cell, and hoof metabolism.

Vitamin B6 (pyridoxine) is an essential B-vitamin naturally found in yeast, grains, and plant-based feed ingredients. It is associated with amino acid and fat metabolism and is included in equine nutrition as part of strategies targeting the nutritional balance of the nervous system and liver.

Vitamin B12 (cobalamin) is an essential B-vitamin found in relevant amounts only in animal-based components such as fermented feedstuffs or yeast. It is involved in nutritional concepts aimed at supporting energy metabolism and nervous system function. Supplementation may be considered particularly relevant for older horses or during periods of increased physical demand.

Niacinamide (vitamin B3) is an essential B-vitamin naturally present in yeast, grains, and plant-derived ingredients. It is included in equine feeding strategies that address energy metabolism and is associated with physiological functions related to skin, muscles, digestion, and the nervous system.

Folic acid (vitamin B9) is an essential B-vitamin that horses must obtain through their diet. It is associated with normal cell metabolism and is included in equine feeding strategies focused on supporting blood formation and general vitality – especially in older horses or during periods of increased demand.

Sodium chloride provides the electrolytes sodium and chloride, which are involved in maintaining the body’s fluid balance and osmotic regulation. A targeted supply may be useful for managing electrolyte intake – particularly in situations involving heavy sweating, physical exertion, or stress.

Withanolides are secondary plant compounds naturally found in the root of the Ashwagandha plant (Withania somnifera). In equine nutrition, Ashwagandha is traditionally used as a supplementary ingredient in rations aimed at supporting inner balance – particularly in sensitive horses or during periods of emotional or hormonal stress.

For large horses, the bundle will last around 1 month. For small horses, it can even last up to 2 months.

The duration of feeding should always be considered individually. Thanks to their natural ingredients, both Nerves Essentials and Mighty Muscles can be fed continuously.

For horses with muscle disorders such as equine myopathies (PSSM / MIM), continuous feeding may be especially beneficial, as it allows the body to be consistently supplied with essential nutrients.

All our products can be prepared in advance for feeding. We recommend a maximum preparation time of 24 hours.

Supplementary feed for horses

Daily amount for large horses
Nerves Essentials 30 ml
Mighty Muscles 30 ml

Daily amount for small horses/ponies
Nerves Essentials 15 ml
Mighty Muscles 15 ml

No worries – 97% of horses eat both - Mighty Muscles and Nerves Essentials - without any problems when mixed with concentrate feed. You can also prepare it in mash. If your horse refuses to eat the product, our 30-day taste guarantee ensures you’ll get your money back.

Yes, absolutely!

A visible change usually appears after about 10 days.

There are no restrictions for the PSSM Bundle. It can be used for all horses of all ages.

Both products should not be fed to pregnant mares.

Nerves Essentials has a 48-hour withdrawal period. Mighty Muscles, on the other hand, is show safe and therefore not doping-relevant.
