Why large dogs benefit from joint supplements
Large and giant breed dogs carry more body weight across their joints than smaller breeds, which makes daily joint care particularly important. Breeds such as Labradors, Golden Retrievers, German Shepherds, Rottweilers, and Great Danes are widely recognised as being more prone to joint stiffness and reduced mobility, often from a relatively young age. Starting a daily joint supplement early helps maintain healthy joint function throughout their life, rather than waiting for signs of stiffness to appear.
What's included in the Starter Pack for large dogs?

- 120 Antinol® capsules - full maintenance supply for dogs over 20kg
- 1 free booster pack of 30 capsules, covering the 15-day loading phase
- Free delivery on your first order
- 60-day money-back guarantee
If you do not see the results you hoped for within 60 days, contact us within 90 days of purchase for a full refund.

What makes Antinol® different from other joint supplements for large dogs?
Many joint supplements for dogs are glucosamine and chondroitin based. Antinol® works differently. Its active ingredient, PCSO-524, is a proprietary marine lipid concentrate extracted from sustainably farmed New Zealand Green Lipped Mussel using a solvent-free, heat-free supercritical extraction process. This protects the integrity of the natural oils and delivers a concentrated, bioavailable formula in a single small soft gel capsule - easy to give whole with food or pierced and mixed in for even the fussiest of large breeds.
Antinol® is recommended by vets, contains only five ingredients, and has no known interactions with other medications or supplements, making it suitable for long-term daily use.
