Meriva® 500-SF: A High-Potency, Soy-Free Curcumin for a Healthy Inflammatory Response

Thorne’s Meriva® 500-SF delivers a potent, clinical-strength dose of the most well-researched curcumin extract on the market. This advanced formula is designed to support a healthy and balanced inflammatory response throughout the body, providing relief for overworked joints and muscles, and supporting the health of the gut and liver. The key to Meriva’s power is its unique, soy-free phytosome technology, which ensures this powerful botanical is absorbed up to 29 times better than standard curcumin extracts.*

How It Works: The Power of the Phytosome for Superior Absorption*

Curcumin, the active compound in turmeric, has remarkable health benefits, but its effectiveness is often limited by poor absorption. Meriva® is a patented curcumin-phospholipid complex that overcomes this challenge.*

Enhanced Bioavailability for Systemic Benefit
The phytosome technology in Meriva® binds the curcumin extract to phospholipids from sunflower. This creates a lipid-friendly molecule that is more easily transported across the intestinal wall and into the bloodstream. This superior bioavailability means a greater amount of active curcumin reaches your cells, providing more effective support for a healthy inflammatory response wherever it’s needed.*

Supporting Joints, Muscles, and More
By helping to maintain a balanced level of cytokines, Meriva® is a foundational supplement for joint comfort, flexibility, and mobility. It also helps to relieve stiffness and reduce delayed onset muscle soreness (DOMS) for athletes and active individuals. In addition, its potent antioxidant properties provide protection for the GI tract, liver, and eyes, making it a comprehensive choice for whole-body wellness.*
