Product Description
Cortaflex® HA Regular powder is designed for the nutritional maintenance of healthy joints in horses and ponies in light to moderate work, or older horses needing a little extra mobility support!
Cortaflex® HA Regular Powder provides a tried and tested blend of key compounds, with low sugar levels, making it suitable for horses and ponies prone to laminitis. Cortaflex® HA Regular Powder includes collagen, hyaluronic acid, trace elements and amino acid building blocks to provide essential nutritional support for maintaining healthy cartilage and joint fluid. Cartilage is the spongy, elastic material which covers the ends of the bones within a joint, acting as a major shock absorber, and helping to reduce friction. Joint or synovial fluid should be thick and viscous, to bathe and lubricate the joint, also acting as a vital shock absorber.

Ingredients & Nutrition
Key Ingredients
Collagen – one of the most abundant proteins in the body, and provides the structural framework for cartilage, to help give it strength and elasticity. We are proud to confirm that we use a sustainable and ethical source of marine collagen.
Hyaluronic Acid – a key compound called a glycosaminoglycan (GAG) which helps to maintain the viscosity of the joint fluid, to lubricate the cartilage and act as an additional shock absorber.
Amino Acids – to provide the nutritional building blocks for the production of the amino sugars. The best known amino sugar is probably glucosamine, which is important as a subunit for the production of other compounds called glycosaminoglycans (GAGs) which then bind to the collagen framework in the cartilage, to help give it greater strength and elasticity.
MSM - provides a natural, bioavailable form of sulphur which is a key mineral for the bonding of compounds within the cartilage framework, to enhance strength, and also helps to support the horse's own anti-inflammatory processes.
Key trace minerals including manganese, silicon and copper - which all play important roles in the production of structural compounds such as chondroitin, as well as in the production of collagen and hyaluronic acid. These minerals also play key roles in the production of important antioxidants.

FAQ
All your questions, answered.





The thermoneutral zone is the temperature range where the body can maintain its core temperature with little to no extra energy expenditure. For humans, this range is quite narrow at 21–28 °C, but for horses it’s much broader at 5–25 °C.
This difference means we should avoid rugging horses based on how cold we feel. Over-rugging can lead to serious health issues, including metabolic problems and thermoregulatory dysfunction.
Tips for Choosing a Winter Rug Weight
-
Clipped horses may need a heavier gram fill to stay comfortable.
-
Remember: horses warm themselves more easily than they cool down under a rug. If unsure, choose a lighter rug.
-
Check your horse regularly to make sure they are neither too hot nor too cold.
-
Consider your horse’s age and natural ability to stay warm.
-
As a general guide, rugging is usually appropriate when temperatures drop below 5–10 °C, but always adjust for your horse’s individual needs.
-
Always ensure rugs are waterproof. A wet rug is worse than no rug at all.
This is an indicative guide only. Always take into account factors such as wind chill, your horse’s age, weight, and condition.
