The formula

Kidney Support Powder, and why it is built this way

Formulated for cats over ten, or any cat with a rising SDMA. Omega-3 at a renal dose, taurine, B vitamins and a potassium salt — and deliberately low phosphorus, because in kidney disease the last thing you need to add is more.

No added phosphorus, no high-dose calcium, no salt.

What it does

Three things you can expect

01

Renal-dose omega-3

EPA and DHA at the levels used in feline kidney studies.

02

B vitamins replaced

Polyuric cats lose water-soluble vitamins in urine.

03

Potassium support

Hypokalaemia is common in chronic kidney disease.

Questions

Before you buy

Can I use it instead of a renal diet?
No. Diet is the primary intervention in feline CKD. This sits alongside it.
My cat is on a phosphorus binder — is this safe?
Usually yes, but tell your vet; the doses need coordinating.
Is it suitable for dogs?
This formula is dosed for cats. A canine version is in development.
