Everything you need to know about vitamin B6 in horse health!
Vitamin B6, also known as pyridoxine , is an essential vitamin in horse nutrition.
It plays a central role in amino acid metabolism and supports protein metabolism as well as the breakdown and synthesis of amino acids.
In horses, vitamin B6 is also involved in carbohydrate metabolism . Incidentally, the need for vitamin B6 increases with protein intake.
Vitamin B6 deficiency is rare in horses, but can lead to various health problems.
What happens if a horse has a vitamin B6 deficiency?

Nervous system disorders: Symptoms may include disorders of the central and peripheral nervous system, such as convulsions or movement disorders.
-
Problems with food intake: Reduced feed intake and poor protein production are further signs.
- Deficiency of important minerals: A vitamin B6 deficiency can also lead to a deficiency of selenium, manganese or zinc.
Function and necessity of folic acid for horses
Folic acid, also known as vitamin B9, is particularly important for the growth and development of foals.
Horses usually get enough folic acid through species-appropriate feeding with green fodder, such as pasture grass, which is rich in this vitamin.
Folic acid plays a crucial role in early embryonic development.
Inadequate intake or problems with intestinal synthesis, particularly in horses that are kept predominantly in stables and have to perform at a high level, can lead to deficiencies.
What happens if a horse has a vitamin B9 deficiency?
-
Poor performance: Horses may show a general weakness in their performance.
-
Anemia: A deficiency in folic acid can lead to anemia.
-
Development problems in foals: In pregnant mares, a deficiency can impair the development of the foal.
- Health problems: Horses that do not have access to sufficient green forage can develop health problems.
Why horses need vitamin B12
Vitamin B12, also called cobalamin , is essential for horses and is synthesized in the horse's intestine with the help of cobalt if the intestinal flora is healthy.
It influences amino acid synthesis, blood formation, and growth. Cobalt is an important cofactor for the production of vitamin B12.
This vitamin plays a central role in cell division, especially in cell-rich tissues such as the intestinal mucosa and nerve tissue .
A healthy intestinal flora is crucial for sufficient vitamin B12.
What happens if a horse has a vitamin B12 deficiency?
-
Poor blood formation and growth disorders: A deficiency leads to anemia and can impair growth.
-
Impairment of nerve function: Neurological problems such as coordination difficulties may occur.
-
Weakened immune system: Vitamin B12 deficiency can weaken the immune system.
-
Skin inflammation: Deficiencies can manifest as skin problems.
-
Reduced protein production: This can affect the horse's health and development.
-
Poor feed utilization: Horses with vitamin B12 deficiency may not utilize food efficiently.
- Rough coat: A deficiency can also be seen in the appearance of the coat.
What is the recommended daily dose for horses?
The recommended daily dose of vitamins for horses depends on various factors, including
- Size,
- Age,
- Activity level and
- Health status of the horse.
It is important to adjust feeding individually to avoid both deficiencies and overdoses.
A balanced diet containing all the necessary vitamins and nutrients is crucial for the horse's health and well-being.
Overdose: Symptoms & consequences at a glance
An overdose of B vitamins in horses is rare but possible.
Symptoms of a vitamin B overdose can vary and range from digestive upset to serious health problems.
It is important to know that an overdose of some B vitamins can occur, especially with uncontrolled supplementation.
An individual dosage should therefore ideally be agreed upon with a veterinarian or a specialist in horse nutrition.
Signs of an overdose include behavioral changes, skin reactions, and other metabolic problems.
If an overdose is suspected, a veterinarian should be consulted immediately to minimize possible health consequences.

Try it now!How do horses store vitamins?
Horses store vitamins differently, depending on their solubility. B vitamins are water-soluble and are not stored long-term; instead, they must be regularly ingested through food.
The horse's body can only store these vitamins to a limited extent, so a continuous supply through your horse's diet is important.
How does poor feed quality affect vitamin B synthesis?
Poor feed quality can negatively affect the synthesis and absorption of B vitamins in horses.
Poor food sources often cannot provide enough essential nutrients, which can lead to a deficiency in B vitamins.
An unbalanced diet can impair intestinal health, which is essential for the synthesis of some B vitamins.
Consequently, poor feed quality can negatively impact the horse's overall health and well-being.
Why is activation so important for the availability of B vitamins?
The activation of B vitamins in the horse's body is crucial for their availability and effectiveness. Many B vitamins, such as B6 or folic acid , must be converted into active forms to be used effectively. This conversion occurs through specific enzymes and coenzymes.
Without this activation, B vitamins cannot be properly metabolized, which impairs their effectiveness.
Good intestinal health and sufficient coenzymes are therefore essential for the effective use of B vitamins in the horse's body.
Conclusion
Even if horse owners don't constantly worry about their faithful companion's vitamin intake in their daily lives, the importance of B vitamins in our horses' lives cannot be overstated. They are essential for development, health, and performance.
A well-planned diet that incorporates these vitamins can be the key to success. However, it's not just about the quantity, but also the quality of the nutrients.
Careful selection and composition of feed ingredients are therefore crucial. Ultimately, the goal is to have a healthy and content horse and to spend many exciting adventures and valuable time together. At Pferdegold, we make every effort every day to ensure our products provide your horse with the best possible nutritional support.
FAQ
What role does vitamin B play in stress management in horses?
Vitamin B can be crucial for stress management in horses because it supports the nervous system.
It can be helpful to mitigate reactions to stress, which is especially important in demanding situations such as competitions or transportation.
An adequate supply of vitamin B therefore often contributes to the animals' resistance to stress and general well-being, which shows how essential a balanced diet can be for the mental and physical health of horses.
How do B vitamins affect the coat quality of horses?
B vitamins, especially biotin, play an important role in the quality of a horse's coat. A balanced vitamin B complex can promote a shiny, healthy coat by supporting metabolism.
Deficiencies can often manifest as dull, weak coats. Therefore, it's important to provide a varied diet to meet these essential nutrients and maintain coat quality.
Can an overdose of B vitamins cause health problems in horses?
An overdose of B vitamins in horses, although rare, can lead to health problems. Because B vitamins are water-soluble, excesses are usually excreted, but extreme overdose can cause imbalances.
It is therefore advisable to always follow the feeding instructions on the packaging and exercise caution when supplementing. If unsure, professional advice may be helpful to minimize the risk of side effects.
