Safety Information

Horsetail contains thiaminase, an enzyme that breaks down vitamin B1 (thiamine). Long-term high-dose use is not recommended. Avoid in individuals with thiamine deficiency, alcoholism, or eating disorders. Not recommended during pregnancy. Choose herbal-grade preparations (typically processed to reduce thiaminase).
