What is perna?
Perna (extract brand names: Lyprinol® and Antinol®) is a supplement made from the green-lipped mussel (Perna canaliculus) and is used as an antioxidant and anti-inflammatory for conditions like arthritis in cats, dogs, and horses. It has also been tried in humans to supplement allergic asthma treatment. Perna contains substances such as chondroitin, fatty acids, and micronutrients.

Dietary supplements are substances that can be used to supplement the diet, such as vitamins, minerals, amino acids, herbs, botanicals, enzymes, and probiotics. While many supplements are sold over the counter, they still contain ingredients that have biological effects that should be managed by your veterinarian. Follow your veterinarian’s directions and cautions very carefully as their directions may be significantly different from those on the label.
There are differences in how countries regulate supplements. In the United States, these substances are not as vigorously regulated by the FDA as other medications, which means they can be sold without the manufacturer proving their effectiveness, safety, and without a guarantee of consistent or accurately reported ingredients. In Canada, products that have been evaluated for quality, safety, and effectiveness by Health Canada and authorized for sale will have a license number on the label.
