Lyprinol contains an extract from a special type of mussel, which is known to be good for the joints. This patented fatty acid extract (PCSO524) is obtained from the green-lipped mussel Perna Canaliculus harvested off New Zealand. There are many different mussel species, but only the green-lipped mussel from New Zealand contains rare anti-inflammatory fatty acids that can relieve sore joints. Lyprinol is naturally produced through patented processes, and documented in over 35 published studies and investigations.
