Synovi G4 builds upon the proven Synovi G3 matrix, a blend of various joint health ingredients, including glucosamine, manganese and Green-lipped mussel, which has sold over 250 million doses. (1) Synovi G4 is enriched with the naturally-derived ingredients turmeric, a potent antioxidant, and Boswellia serrata. Laboratory studies have shown that turmeric and Boswellia serrata help support a healthy inflammatory response. (2,3)

Synovi G4 is based on the proven joint support matrix found in Synovi G3 which contains Perna canaliculus, also known as Green-lipped mussel, found off the coastal waters of New Zealand. Perna is a rich source of chondroitin as well as omega-3 fatty acids.
These two ingredients were added because they are not commonly found in traditional joint supplements and are known for a variety of health benefits. A growing body of evidence indicates that both Boswellia and Turmeric may be beneficial in the support of healthy joints, including cartilage and connective tissue, as well as a healthy inflammatory response.
Boswellia serrata, also known as Indian frankincense, is a large branching tree native to India, North Africa, and the Middle East. The tree’s resin contains boswellic acids, which have shown in laboratory studies to support a healthy inflammatory response1 and promote joint health. Boswellia serrata may also help with occasional discomfort and joint stiffness due to daily activity.
