Mad Barn’s B-Vitamin Pak is a comprehensive, powdered formula that delivers a balanced profile of all the B-vitamins that your horse needs.
We dare you to compare B-Vitamin Pak – you will not find a lower priced/higher quality B-vitamin equine supplement on the market!
The complex of B-vitamins is made up of thiamine (B1), riboflavin (B2), niacin (B3), pantothenic acid (B5), pyridoxine (B6), biotin (B7), folic acid (B9), and cobalamin (B12).
Together, these essential nutrients are chiefly involved in the metabolism of fat, protein and carbohydrates, proper functioning of the liver and blood production. Supplementing with B-Vitamin Pak can support your horse’s well-being, mood, energy levels, coat quality and more.
Why Supplement B-vitamins in your Horse?
The horse is able to synthesize the majority of B-vitamins in the hind gut, thanks to its bacterial population. These vitamins are also very efficiently recycled within the body and not typically needed in large quantities in the diet.
For this reason, it is common for equine nutritionists to indicate that horses do not need supplemental B-vitamins to prevent deficiency.
However, studies consistently show that supplementing 20 mg/day of biotin will improve hoof growth and structure. This is why all Mad Barn mineral and vitamin products provide 20 mg of biotin/day.
This indicates that endogenous production levels of B Vitamins is not sufficient for optimal health with current feeding and management practices.
Similarly, if you supplement thiamine and note an improvement in your horse’s mood and behaviour, then clearly B-vitamin levels were insufficient prior to supplementation.
When to Use B-Vitamin Pak
Supplementing B-vitamins with Mad Barn’s B-Vitamin Pak can especially assist horses:
- Undergoing intense training or competition
- Lower than ideal B-complex levels may negatively impact horses that spend a lot of time off pasture, adhere to strict schedules or other management practices that are seen in horses that are engaged in high levels of training and competition. Supplementing B-vitamins can restore optimal levels.
- Under stress due to transportation
- Disruptions in your horse’s feeding schedule, changes in the environment and changes in diet can all contribute to increased stress, which can compromise gut health and weaken the immune system.
- With a reduced digestive capacity
- Very young horses may have a low bacterial population in their hind gut, meaning they are not able to produce adequate levels of these vitamins internally.
- Very old horses often have a lower feed intake and digestive capacity due to age-related conditions, which could lead to lower levels of B-vitamins in the body.
- Affected by an illness
- Poor appetite can accompany illness; replenish B-vitamins that can’t be obtained from normal feedstuffs.
- Medications such as NSAIDs or antibiotics may compromise hind gut bacteria.
- Fed high-grain diets
- High grain diets tend to cause dysbiosis in the hind gut and a subsequent reduction in B-vitamin production.
- With limited access to green grass or quality hay
- Fresh grass is rich in many B-vitamins. Depending on the harvest, hays can also contain adequate levels. However, during times when fresh grass or quality pasture aren’t available, B-vitamin supplementation can be helpful.
You should always consult a qualified nutritionist before altering your feed program. Submit your horse’s diet for analysis online and one of our equine nutritionists will be happy to provide a complementary review.
Biotin, also known as Vitamin B7, is a water-soluble B-vitamin that plays an important role as an enzymatic cofactor in metabolism. Most notably, biotin is involved in the enzymatic reactions that synthesize keratin, which is a component of skin, hair and hooves.
Horses are not capable of synthesizing biotin, and so it must be obtained from the diet. Outright deficiency is rare as biotin is found in most common feedstuffs. Dietary sources of biotin vary, with fresh pasture and alfalfa being the top sources, followed by oats, barley, soybean meal, corn and molasses.
Because it is present in such small quantities in most feedstuffs, the supplementation of biotin is recommended for horses, especially those with dry, cracked or brittle hooves, horses that pull shoes often or horses with chronic laminitis.
Adding biotin to a well-balanced diet can improve hoof health by producing strong keratin. Biotin supplementation has been shown to improve conditions such as brittle hoof horn and chipped hooves. In addition, it contributes to a healthy coat.
Research on the supplementation of pure biotin in equine diets has resulted in mostly positive results, mainly when looking at hoof growth rates, and it is widely advised that biotin be supplemented at 20 mg per day in order to see substantial improvements in hoof growth.
Choline is an important nutrient for nerve function, fat metabolism, liver health and for maintaining reproductive health. In addition to serving as a building block for cell membranes, choline is also a precursor of the neurotransmitter acetylcholine which regulates motor movements and cognitive function.
This nutrient is closely related to the vitamin B family. It is a constituent of lecithin which is a type of fatty substance known as a phospholipid. Deficiency in choline is unlikely and it has an established Recommended Dietary Concentration of 50 mg/kg of dry matter intake.
Choline supplementation is recommended for horses to support neurological health and to promote normal liver function. It plays an essential role in fat metabolism in the liver and helps to prevent excess accumulation of lipids.
Vitamin B12 (Cobalamin) is a water-soluble vitamin with important roles in the nervous system, liver function, energy metabolism and red blood cell maturation. As a dietary supplement, it is sometimes given to horses to fight symptoms of fatigue and stress or to address digestive problems.
The horse needs cobalamin to ensure normal production of red blood cells in bone marrow, to maintain a healthy reproductive system and to support myelination of nerve pathways. Vitamin B12 is also involved in the metabolism of lipids (fats) and amino acids. This vitamin is said to improve physical stamina and to stimulate the appetite in horses.
Unlike other B-Complex vitamins, B12 is not produced naturally within plants and cannot be gained through the horse’s diet. Instead, it must be synthesized within the horse’s hindgut through bacterial fermentation from the mineral cobalt. While deficiency is rare, there may be times when providing additional Cobalamin by way of supplements can improve well-being.
Folic Acid (folate, Vitamin B9) is a water-soluble vitamin that is involved in DNA synthesis, methionine production and cellular growth and development. It is particularly important for supporting cell turnover during periods of rapid growth such as fetal development, tissue repair and regeneration of cells lining the intestinal wall.
Folic acid is sometimes given to horses to improve hemoglobin levels because of its role in maintaining healthy red blood cells. Deficiency in folate can manifest as megaloblastic anemia, but this has only ever been reported in other species and not in horses.
Folic acid is generally supplied in adequate amounts in the horse’s diet, especially for animals on pasture or those with access to fresh forage, alfalfa, timothy hay and cereal grains. Horses fed hay tend to have lower levels of this vitamin in their blood.
Horses currently being treated with sulfadiazine and pyrimethamine for EPM may require supplemental folic acid because these medications interfere with the absorption of this vitamin from the gastrointestinal tract.
Niacin (Vitamin B3, nicotinic acid) is a water-soluble vitamin that is involved in a wide range of activities within the horse’s body. It has been shown to influence nutrient metabolism, digestion, nerve function, blood circulation, skin health and more.
Horses typically require 35mg of Vitamin B3 per day and deficiency is not a problem in most parts of the world. However, horses may benefit from supplementation with this vitamin in certain cases.
Niacin can be synthesized in the horse’s liver from tryptophan and is products in the cecum by certain species of bacteria. It is also found in alfalfa, soybean meal and timothy hay, but only unbound forms of this vitamin can be utilized by the body.
When supplementing with higher levels of protein, Niacin requirements may be increased. Horses engaged in light to heavy work also require more, 60mg and 100mg respectively.
Pantothenic Acid (Vitamin B5, pantothenate) is a water-soluble vitamin that is critical for normal metabolic function in the horse. Pantothenic Acid forms a part of co-enzyme A (CoA) which is involved in energy production, fatty acid synthesis, production of steroid hormones, formation of neurotransmitters and regulation of other enzymatic reactions.
Low dietary intake of Pantothenic Acid can result in fatigue, but true deficiency is rare. Horses typically obtain adequate amounts of this vitamin from their forage and grain. It can also be produced through fermentation by bacteria in the gut.
Performance horses and animals that experience gastrointestinal upset or those using antibiotics may benefit from additional supplementation with Vitamin B5. The recommended dietary concentration is 13 mg/kg of dry matter intake.
Pyridoxine (Vitamin B6) is a water-soluble vitamin that is required for proper metabolic function in the horse. It plays a role in blood sugar regulation, muscle development, mood regulation, hormone production and joint health.
Pyridoxine is necessary for over 150 different enzyme reactions in mammals. It is essential for helping the body to process lipids, carbohydrates and proteins from food. Vitamin B6 also has antioxidant and anti-inflammatory mechanisms and can influence the nervous system and immune function.
Supplementing with B Vitamins may be particularly beneficial for horses primarily eating grain and not forage, undergoing intense physical exertion, high stress environments, young or old horses, and those taking antibiotic medications. Horses with certain forms of digestive upset such as diarrhea or dysbiosis that impede absorption of nutrients may also benefit from taking additional Pyridoxine.
Riboflavin, or vitamin B2, is a water-soluble vitamin that is essential for converting macronutrients such as carbohydrates, proteins and fats into energy. It is a precursor for the synthesis of enzymes involved in ATP production and lipid metabolism.
Riboflavin is present in all cells of the body and is used to make two very important coenzymes, flavin adenine dinucleotide and flavin mononucleotide. Coenzymes are molecules that assist enzymes by delivering molecules that the enzymes need to perform a reaction.
Riboflavin is naturally present in the horse’s diet, most abundantly in legumes such as alfalfa and clover and slightly lower in grass hays. Riboflavin is also produced by fermentation in the hindgut. Like most B vitamins, riboflavin deficiency and toxicity are very rare and have not been reported in horses.
The microbes in a horse’s gastrointestinal tract are able to synthesize Vitamin B2, and requirements are easily met with the addition of hay and grain. Symptomatic riboflavin deficiency is so rare, that signs are not reported in horses even when fed diets that are lacking in this vitamin.
The supplementation of riboflavin and other B vitamins can help to supply optimal levels and allow the horse to perform at its full potential, especially in certain situations. Horses consuming low-quality hay, those under high stress, on antibiotics or have any health condition that compromises hindgut bacterial production is recommended to receive a B-vitamin supplement.
Thiamine is one of the B vitamins and is also known as vitamin B1. This very important vitamin is crucial for the enzymes that carry out carbohydrate metabolism and the functioning of the nervous system. Horses are able to synthesize thiamine with the help of microbes in the hindgut, and so it is generally not necessary as a supplement.
Levels of thiamine are highest in brewer’s yeast and rice bran, with the lowest concentrations found in forages.
Some research has found that thiamine is still required in the diet due to reports of inadequate synthesis, despite it being produced in the hindgut. Studies suggest that exercising horses, especially, may require double what a horse at maintenance needs to support increased carbohydrate metabolism. Positive effects have been seen with the supplementation of thiamine on markers of carbohydrate metabolism and thiamine status of exercising horses, so it may be beneficial to supplement performance horses with thiamine.

Read more answer nowAsked by November 13, 2019 11:50 amonAnswered by the admin B-vitamins play a role in producing chemicals in the brain and maintaining tight junctions, so depending on the horse's vitamin status b-vitamin supplementation may have a profound impact or none on behaviour and/or mood. The majority of b-vitamins are produced in the hindgut by the bacterial population. High grain diets tend to cause dysbiosis and subsequent reduction in b-vitamin production. It is common for nutritionists to indicate horses do not need supplemental b-vitamins, due to the fact the microbial population produces them. Studies consistently show that supplementing 20 mg/day of biotin will improve hoof structure (which is why Mad Barn mineral and vitamin products all provide 20 mg of biotin/day), indicating endogenous production levels are not sufficient for optimal health with our current feeding and management practices. Similarly, if you supplement thiamine and note an improvement in your horse's mood/behaviour than clearly b-vitamin levels were insufficient prior to supplementation.
