WHAT IS ROSEMARY LEAF EXTRACT?

Rosemary is a member of the mint family. Its common name derives from Latin and translates as “dew of the sea.” Rosemary was used as a spice and herb by Egyptians, Greeks, and Latins cultures, thriving close to the coast, especially in dryer areas throughout the Mediterranean. Rosmarinus officinalis contains a range of health-supporting polyphenols, including diterpenes (e.g., carnosol, carnosic acid, rosmarinic acid), triterpenes (e.g., ursolic acid), and flavonoids (e.g., luteolin).* The diterpenes carnosol and carnosic acid are potent antioxidants that account for over 90% of the antioxidant activity in rosemary leaves [1].* 

NEUROHACKER’S ROSEMARY LEAF EXTRACT SOURCING

Rosemary Leaf Extract is standardized to contain 7.5% Carnosic Acid + Carnosol.

Rosemary Leaf Extract is gluten-free, non-GMO, vegan, Kosher, and Halal certified.

ROSEMARY LEAF EXTRACT FORMULATING PRINCIPLES AND RATIONALE

We believe that rosemary extracts standardized for diterpenes should be thought of as following a threshold response (see Neurohacker Dosing Principles). This means that beyond a certain amount, there may be no additional functional benefits gained. As an example, a skin health study supplemented either 50 mg or 125 mg of a rosemary extract combined with similar amounts of a citrus extract. The lower amount performed as well as the higher amount [2]. In several skin studies where rosemary has been combined with lycopene-rich tomato fruit extracts, the serving used was also an amount closer to this 50 mg range of a standardized extract. Our serving for this rosemary extract was selected to be consistent with an amount that has been used when rosemary extracts have been combined with other skin health ingredients.*
