Ginger is the common name for the whole or cut rhizome—the underground stem or vertical portion of the root—of the plant Zingiber officinale. Ginger has a long history of use as a food spice—it is one of the most widely used spices in the world. It also has a long history of use in Traditional Chinese Medicine (TCM), Ayurveda, and other healing systems. Ginger can be used alone, but is very commonly a part of poly-ingredient herbal combinations. In Ayurveda, as an example, the combination of ginger, black pepper, and long pepper, called Trikatu (“three pungent spices”), is frequently used together and also added to many other herb mixes. Modern science has discovered that ginger is a bioenhancer, positively influencing the bioavailability of some other compounds, which may partly explain why it’s often been combined with other herbs. Ginger contains many bioactive compounds, including several phenolic and terpene compounds. Gingerols, the compounds primarily responsible for the pungency of ginger root, are one of its main bioactive compounds. These pungent principles give ginger it’s characteristic flavor and spiciness; they also confer a number of health benefits. Ginger was used for a large number of health purposes historically. Modern science continues to investigate ginger in a wide range of areas, including brain, gastrointestinal, metabolic, musculoskeletal, and vision health.*
Ginger Root Extract is standardized to contain not less than 5% Gingerols. Gingerols are among ginger’s main bioactive compounds that confer a number of health benefits.
Ginger Root Extract is gluten-free, non-GMO, vegan, Kosher, and Halal certified.
Standardized ginger root extracts have been typically dosed from several hundred to 800 mg when used alone in human clinical studies. Given the responses to ginger in studies that have compared different doses, we consider ginger extracts to follow threshold dosing principles (see Neurohacker Dosing Principles), where much of the benefits occur in the lower-to-middle end of the dosage range. When ginger extracts are combined with other herbs, the amount used would normally be at the low end of the range. The serving of ginger extract used in our formulas will be dictated by what it’s being used to do and will follow amounts consistent with using an extract with a standardized amount of gingerols, ginger’s main bioactive compounds. When ginger extract is in a formula primarily for its role as a bioenhancer to enhance the bioavailability of other ingredients, the serving will be low (similar to piperine, it has not required a high amount of ginger for bioenhancement). When used for other purposes, the serving will be consistent with ranges for that purpose taking into account the other herb extracts used in combination with the ginger extract.*
