How to use Antinol® for cats
Getting started with Antinol® is straightforward. Follow the two-phase protocol below for the best results:
Days 1 to 15 (loading phase): Give your cat 2 capsules per day. You can give them together with a meal or split across the day, whichever works best for your cat.
Day 16 onwards (maintenance phase): Reduce to 1 capsule per day. Continue daily as part of your cat's regular routine.
If your cat is reluctant to eatcapsules whole, pierce the capsule and squeeze the oil directly onto their food. The oil has a mild natural flavour that most cats accept well. Results vary between cats. We recommend completing the full 60-day protocol before assessing progress.

What is joint care for cats?
Joint care for cats is a category of nutritional supplements designed to help maintain healthy joint function and support day-to-day comfort and mobility in healthy cats. Unlike dogs, cats are experts at masking signs of joint stiffness, which is why many pet owners choose to support their cat's joints proactively, as part of a daily routine. A good joint care supplement for cats should be easy to feed, made from high-quality natural ingredients, and safe for long-term use. Antinol® meets all three criteria. Each soft gel capsule contains 50mg of PCSO-524, a proprietary marine lipid concentrate sourced from Green Lipped Mussel, combined with olive oil and vitamin E. Nothing artificial. Nothing unnecessary.
What's included in the Antinol® Starter Pack for cats?
The Antinol® Starter Pack is designed specifically for first-time customers. It is the easiest and most cost-effective way to give joint care for cats a proper trial, with everything you need included from day one.
The pack contains:
- 60 Antinol® capsules, a full 60-day supply
- 1 free booster pack of 15 capsules (valued at £10.75), covering the initial loading phase
- Free delivery on your first order
- 60-day money-back guarantee
The free booster pack is included because we always recommend you feed them a higher amount (2 capsules per day) for the first 15 days. This gives your cat the best possible start. After day 15, you move to 1 capsule per day for ongoing maintenance. The Starter Pack is sized to cover both phases in full.
If you don't see a difference within 60 days, contact us within 90 days of purchase for a full refund. No partial refunds, no conditions. That is the Antinol® guarantee.
