NATURAL BIOLOGY ON THE VALUE OF ANTIOXIDANT ORAC & EFFICACY

Present study was carried out to standardize the oxygen radical absorption capacity (ORAC) assay for the estimation of antioxidant value of botanicals indigenous to Indian subcontinent by taking Amalaki (Emblica officinalis) and an Ayurvedic proprietary polyherbal formulation (PHF) as a representative standard. The ORAC assay for ethanolic and aqueous (Organic Amla-C®) extracts of Amalaki and PHF were carried out using 96-well flat optical bottom clear black plates by the use of sensitive florescent multiple plate reader and fluorescein as a probe, vitamin C was used as a reference standard. The assay was found to be simple, versatile, reproducible, and can be widely used for estimating the total antioxidant activity of the herbs and propriety PHF. The study also highlights Amalaki and Himalaya PHF as rich sources of antioxidants. The antioxidant activities of Amalaki extracts were found to be slightly more than vitamin C and similarly the antioxidant activity of Himalaya PHF was comparable to that of vitamin C (in terms of total ORAC values). ORAC means Oxygen Radical Absorption Capacity and it is the method used to measure the potency of an antioxidant.  Most of the time it is a useful measurement however just because something has a high ORAC  does not mean it has a high efficacy - how it works in humans.   Often lab ORAC test do not mean that the ORAC's effectiveness was tested in humans in clinical trails.   Natural Biology only uses well-studied antoxidant that have passed both human efficacy results as well as good ORAC values. Natural Biology uses the following high ORAC antioxidants that have equally high efficacy results: Alpha Lipoic Acid Resveratrol - from French Red Wine Grape Extract CoQ10 Pomegranate Extract Green Tea Extract Grape Seed Extract Acaii Extract Goji Berry Extract Noni Extract Gingo Biloba Querceting Gluatamine Antioxidants Beyond the Hype - Harvard Study  Red Wine and Cancer Prevention: The Facts
