What are the therapeutic benefits of Perna®? Perna® is a multi functional and natural product which has anti-inflammatory, chondro-protective and gastro-protective properties. It has had significant success in treating a number of joint and muscle related problems, not only in humans but in animals too. Research has shown it has a greater range of beneficial effects than either Glucosamine Sulphate or Chondroitin Sulphate. Through early trials Perna® Green Lipped Mussel extract was shown to have gastro-protective activity. It does not cause any harm to the stomach or kidneys; it actually protects the stomach. It has the ability to reduce the ulcerogenic effect of non-steroidal, anti-inflammatory drugs (NSAIDs) such as aspirin and indomethacin, whilst complementing the anti-inflammatory potency i.e. they can be used together if need be.
