Does EquiNectar work? Where's the proof?



EquiNectar, a scientifically developed supplement, is designed to enhance the nutritional health and gut microbiome of horses. This blog delves into the claims surrounding EquiNectar, providing evidence and explaining how it supports these vital aspects of equine health.


EquiNectar improves nutrition

Nutrition encompasses the intake of food and its conversion into energy and essential nutrients necessary for life. This process involves the utilisation of various nutrients such as carbohydrates, fats, proteins, vitamins, minerals, and roughage. EquiNectar aims to improve this nutritional process by supplementing horses with digestive enzymes. These enzymes are critical in breaking down feed components, thus facilitating a more efficient nutrient absorption.

What are Digestive Enzymes?

Digestive enzymes are vital for the breakdown of food ingested by horses. They accelerate the chemical reactions that convert nutrients into substances absorbable by the horse's digestive tract. While horses naturally produce these enzymes, the levels may not suffice for adequately digesting high quantities of fructans (from grass) or starch (from grass, hay or feed). Here, EquiNectar steps in by providing these essential enzymes, thereby supporting the horse's natural digestive process.


EquiNectar supports a healthy gut microbiome

The gut microbiome is a complex ecosystem within the digestive tract, comprising numerous microorganisms that play a crucial role in health, including digestion, immunity, and metabolism. A balanced gut microbiome is essential for overall health, and EquiNectar contributes to this balance by optimising the conditions for beneficial bacteria to thrive. By enhancing digestion with enzymes, EquiNectar can help prevent undigested feed from reaching the hindgut, which can disrupt the microbiome balance and lead to health issues.


Where's the evidence?

Digestive enzymes and horse health

The efficacy of adding digestive enzymes to a horse's diet is supported by various studies. These enzymes have been shown to significantly improve the digestion of nutrients, which can enhance the overall health and performance of horses.

  • A study published in the Journal of Equine Veterinary Science [1] highlights the positive effects of enzyme supplementation on digestibility and nutrient absorption in horses.
  • Research in the Livestock Science [2] demonstrates how enzyme supplements can improve the efficiency of fibre digestion, crucial for equine health.
  • Further evidence is provided by a study in the Journal of Equine Veterinary Science [3], which shows that enzyme supplementation can enhance the breakdown and absorption of starch, a common component of equine diets.

EquiNectar specific research

EquiNectar's role in adding beneficial digestive enzymes to a horse's diet is underscored by research specifically focusing on this supplement.

  • A study from BEVA’s Equine Veterinary Journal [4] outlines the benefits of EquiNectar in supporting gut health and improving feed efficiency.
  • Another Equine Veterinary Journal study [5] confirms these findings, emphasising EquiNectar's positive impact on the gut microbiome and overall horse well-being.
  • Research published in Integrative Food, Nutrition and Metabolism [6] further elucidates EquiNectar's role in enhancing the equine gut microbiome, showcasing its utility in promoting a healthy digestive system.
