Standard Extract

The term "standard extract" indicates that the product has been processed to contain specific and consistent amounts of certain active ingredients. The amount of active ingredient is usually expressed as a percentage. For example, a standardized ginkgo biloba extract may be formulated to contain a specific percentage of flavonoids and terpene lactones. For manufacturers, standardization can be used as a quality control measure to maintain consistency in product composition, potency and efficacy. For consumers, standardization means that you know exactly what the product contains.

Alfa Chemistry is committed to providing you with a range of high-quality standard extracts. We adhere to the highest industry standards and utilize rigorous testing and quality control measures to ensure the purity and authenticity of our standard extracts.
