Why we chose hydrolysed casein

We built AC for Pets around hydrolysed casein because of the research behind it. It contains alpha-casozepine, a peptide derived from milk protein that has been studied in dogs and cats, including in placebo-controlled trials.

Before your first scoop

How do I give AC for Pets?

Sprinkle the amount shown on your tub over your dog’s or cat’s usual food, or mix it into a little wet food. Use an unpacked, level scoop, with dosing guidelines also published here.

How long does it take to work?

Some owners report a change within 2–4 days of starting. Others notice continuing improvement for weeks. Timing varies by pet. Look for small changes, such as settling more readily or resting for longer.

Is this the same as Zylkene?

Both use hydrolysed milk protein as a source of alpha-casozepine. AC for Pets is a simple hydrolysed casein powder made in New Zealand with no added maltodextrin. Zylkene capsules contain maltodextrin, a highly refined carbohydrate made from starch. In our November 2026 Australian price check, a 450 mg equivalent scoop of AC for Pets cost A$1.85, compared with an average of A$2.93 per Zylkene 450 mg chew, before delivery.
