  1. What Are the Benefits of Rosemary Supplements?
    Rosemary supplements are commonly used to support cognitive function, antioxidant protection, and overall wellness. Rosemary contains beneficial plant compounds, including rosmarinic acid and carnosic acid, that help protect cells from oxidative stress and may support memory, focus, and a healthy inflammatory response. Many people incorporate rosemary supplements into their daily routine to promote brain health and general vitality.
  2. What Are the Side Effects of Rosemary Supplements?
    Rosemary supplements are generally well tolerated when used as directed, but some individuals may experience mild side effects such as nausea, upset stomach, or heartburn. People with allergies to plants in the mint family may be more likely to experience an allergic reaction. Rosemary may also interact with certain medications, including blood thinners, blood pressure medications, and diabetes medications, so it's important to consult a healthcare provider before use if you have a medical condition or take prescription drugs.
  3. How Much Rosemary Should I Take?
    The appropriate dosage of rosemary depends on the specific product, extract strength, and intended use. Always follow the serving size recommendations on the product label, as standardized extracts can vary significantly in potency. Taking more than the recommended amount is not necessarily more beneficial and may increase the risk of side effects. Many rosemary supplements are intended for daily use and may be taken with food to improve tolerance.
  4. What Is Rosmarinic Acid?
    Rosmarinic acid is a naturally occurring antioxidant compound found in rosemary and other herbs in the mint family. It is one of the primary active compounds in rosemary and is often used to standardize rosemary extracts for consistency and quality. Rosmarinic acid helps protect cells from oxidative stress and has been studied for its potential role in supporting cognitive health, immune function, and a healthy inflammatory response.
  5. What Does “Standardized Extract” Mean in Swanson Rosemary Extract?
    Swanson Rosemary Extract is made with a standardized rosemary extract, meaning it is processed to provide a consistent level of key naturally occurring compounds in every serving. Standardization helps ensure uniform potency and quality from batch to batch, making it a convenient way to incorporate rosemary's beneficial plant compounds into your daily wellness routine.
  6. Is Swanson Rosemary Extract Suitable for Special Diets?
    Swanson Rosemary Extract is made with non-GMO ingredients, making it a convenient choice for individuals seeking a non-GMO herbal supplement. However, this product is not gluten free and is not suitable for vegetarian or vegan diets.
