How does NSI® Hawthorn Extract work?
Hawthorn extract (Crataegus oxyacantha, Crataegus monogynarich) is often used to promote healthy cardiovascular function by supporting the contractions of the heart muscles, coronary artery blood flow and blood pressure.

NSI Hawthorn is formulated from the purest standardized form, using a higher dosage of active ingredients. The standardization is achieved by isolating the small portion of a plant or herb that contains the most active and effective ingredients. As a result, you are rewarded with the most potent health benefits. And while these standardized herbs may cost a little more, the higher quality ingredients ensure a product truly designed for your optimal health.

Due to the narrow safety index of prescription cardiac medications, such as dioxin, it makes sense for people taking these drugs for congestive heart failure to consult with their doctor before using hawthorn-containing products. Reports of hawthorn interacting with digitalis to enhance its effects have not been confirmed.

Pregnant or lactating women, diabetics, hypoglycemics, and people with known medical conditions and/or taking drugs, should consult with a licensed physician and/or pharmacist prior to taking dietary supplements.
