Equine America Cortaflex High Strength With Super Fenn Powder

Performance horses’ joints are subjected to extreme forces during both training and competition, and cartilage and joint fluid are often the first areas to show signs of wear and tear. Cartilage is the spongy, elastic material that 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.

Cortaflex® HA Super Fenn Powder provides the nutritional building blocks to help the specialized cells in cartilage, called chondrocytes, to maintain the repair process, as well as providing hyaluronic acid to help maintain healthy joint fluid.

Providing powerful joint support for performance, racing and competition horses, or older horses with significant levels of wear and tear. Contains a unique combination of collagen, amino acid, hyaluronic acid and trace elements, delivering the important nutritional building blocks to support joint health. Also contains Boswellia and MSM to support a normal inflammatory response, promoting joint and muscle comfort in hard-working horses.

What are the benefits of Cortaflex® HA Super Fenn Powder?

Supporting cartilage (collagen, MSM and manganese)
Antioxidant defence (MSM and copper)
Synovial fluid support (hyaluronic acid)
Joint and connective tissue support (MSM, manganese and silicon)
Supporting anti-inflammatory processes (Boswellia, MSM)

Collagen – an important compound needed to produce the water-based matrix or structural framework of the 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 glycosaminoglycan (GAG) which helps to maintain the viscosity of the joint fluid, to lubricate the joint and act as a shock absorber.

Amino acids to provide the building blocks for the production of the amino sugars such as glucosamine, which is a structural subunit in the production of other glycosaminoglycans (GAGs) which bind to the collagen matrix to help maintain strong and functional cartilage.

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.

MSM, providing a bio-available source of sulphur to support the sulphur-containing bonds in the cartilage matrix.

Boswellia provides antioxidants and other important phytochemicals to support joint health and comfort as well as the horse's own anti-inflammatory processes.

How long will it take for my order to arrive?

We want to be crystal clear when it comes to managing your expectations; our website is stock managed to show you what items are available for same day dispatch and those which are externally warehoused and therefore, will take a little longer to arrive with you.

Simply make your product selections and a message will pop up telling you how long it will take us to dispatch your order; we call this our product availability message.  If you are happy with the product availability message on the item, checkout your order and we will ship your order in the timeframe stated.

If you have lots of items in your basket, please use the longest product availability message to work out when your order will arrive.  We care about our environmental impact, so we don't split ship orders unless you get in touch to request that we do so.  We will let you know on your order confirmation when we expect your order will arrive with you.

Whilst we do our best to meet the handling times stated in the product availability message, occasionally we can experience some delays in the delivery network.  At these times, a team member will email you to keep you updated on the progress of your order.

Selecting FedEx or DPD does not change our expected handling times; the service selected is always from the point of despatch not purchase.

If you do require an order urgently, please contact us before ordering to ensure we can accommodate your requirements as we hate to be party poopers!

Which couriers do you use?

Before choosing a courier, please make sure you are happy with the product availability message as these handling times apply before we ship your order.  If it doesn’t show “Express warehouse: immediate despatch”, it will not leave us on the same day you have placed the order.

We use FedEx, DPD and Royal Mail for most of our deliveries.  Some large items may come with other trusted 3rd party couriers.

Our Royal Mail economy service is usually delivered in two - three days.  You will receive a text message and an email confirming the day of delivery; Royal Mail provide a four hour time window for delivery.

FedEx and DPD are delivered next working day from point of despatch for UK mainland addresses or in two working days for Scottish Highlands, Islands, Northern Ireland, and Irish addresses.  You will receive a text message and an email confirming the day for delivery. 

Selecting FedEx or DPD does not mean your order will bypass our handling times; FedEx and DPD are from the point of despatch, not the point of purchase. 

If an item has an "Oversized goods must select FedEx" overlay on it, please ensure you select FedEx as your delivery option to avoid any delays with your order.
