Day Son & Hewitt Logo



Unlike many of our competitors, we manufacture our products in our own factory. In fact, the entire range of Day, Son & Hewitt products are manufactured at our plant in Lytham.

In-house manufacturing gives many advantages, not least, control over the process from start to finish. It also affords flexibility in the manufacturing process to allow us to react quickly to the demands of our growing customer base.


Quality is something that we are fanatical about. Although there are no specific manufacturing requirements or standards laid down for the manufacture of Equine Supplements, we have for many years manufactured to pharmaceutical standards.

This standard is known throughout the world as cGMP and simply stands for Good Manufacturing Practice. You can rest assured, when dealing with a company that is GMP certified that they always work to the highest standards.

Our team of qualified personnel monitor the production process from the arrival of the raw materials to the shipping of the finished product. Every single ingredient we use has its own Certificate of Analysis and this gives instant traceability back to the source, should any problems occur.

This ensures that you have complete peace of mind when using our products.
