Standardization
Wide variations in active ingredients are characteristic of any botanical. For example, when Pharmanex analyzes potential Ginkgo biloba leaves, studies reveal the concentrations of active components will vary by as much as 300 percent depending on season, climate, soil, method of harvest, storage conditions, and processing. Pharmanex optimizes the active ingredients of a product through strict, proprietary standardization processes (to at least one relevant marker molecule). Each capsule of a Pharmanex® product contains the same amount of each active ingredient.
