Our vitamins and nutritional supplements are carefully manufactured with the highest quality standards. Throughout the manufacturing process, meticulous quality assurance procedures are followed to ensure high quality finished products.

All products are rigorously tested by independent, FDA-inspected laboratories with particular expertise in the analysis of nutritional supplements. These tests evaluate the identity, potency and purity of each product through the most reliable analytical methods available, including:

• High Performance Liquid Chromatography (HPLC)\
• Gas Chromatography (GC)
• Spectrophotometric Analysis
• Atomic Absorption

Additionally, our standardized herbal extracts are tested to guarantee the proper amount of each active compound.

Prior to their release, our vitamin and supplement products are tested for disintegration and weight variation using methods outlined in the United States Pharmacopeia. These testing procedures ensure that the products will break down properly in the body.
