Boswellin® is a clinically studied, standardized extract from Sabinsa containing 70% boswellic acids—the active compounds that inhibit inflammation. This ensures consistent therapeutic potency in every capsule.

Boswellin® provides anti-inflammatory action similar to NSAIDs but without the harmful long-term side effects like stomach ulcers, kidney damage, or cardiovascular risks associated with pharmaceutical NSAIDs.

Most people notice improvements in joint comfort and mobility within 4-8 weeks of consistent daily use. Boswellic acids work cumulatively to support a healthy inflammatory response.
