Nature's Sunshine Sinus Support EF® (100 caps)*
Provides nutritional support of respiratory cleansing and tissue-protecting processes. The herbs in Sinus Support EF provide practical and safe support for the respiratory system, especially during seasonal changes. Sinus Support EF supports nasal passages and supplies nutrients for proper respiratory function. Sinus Support EF features synephrine (from immature orange peel), which possesses properties somewhat similar to the alkaloid ephedrine in providing respiratory support, but it acts much more mildly in the body.
