Immunity Support For Cats

When your cat’s immune system is at its peak, they don’t need to worry too much about infections. But what if their immune system isn’t at the top of its game? A weak immune system means your cat’s body can’t fight off bacteria and viruses, making them far more susceptible to getting ill. To help build their natural immunity back up, you need to be providing them with the right nutrition. This includes giving them vitamins, minerals and essential amino acids through their food or external supplementation in order to strengthen their body from within and keep them feeling happy and healthy.

Great product. My cat, biscuit, is doing better after only a few days of L-Lysine having been poorly for months and meds from the vet making no difference. She also loves taking them which is a real bonus.

Noticed my cat wasn't feeling their usual selves nor eating as much, a bit of research and some L-Lysine seems to have sorted the problem

We noticed our cat feeling unwell, at first we thought she was being lazy but now we've realised it was her immune system. L-Lysine has made her more active again.
