Potential Cancer Risk Reduction: ASU may help reduce the risk of hormone-dependent cancers such as breast and prostate cancer, along with other types.
Rheumatoid Arthritis Treatment: Effective in treating rheumatoid arthritis by alleviating symptoms and improving joint health.
Anti-Inflammatory and Joint Health: ASU blocks pro-inflammatory chemicals, prevents the deterioration of synovial cells (which line the joints), and may aid in regenerating normal connective tissue.
