Based on scientific evidence, daily antioxidant intake should increase to 3,000 to 5,000 ORAC units per day to reach a significant antioxidant capacity in blood plasma and other tissues. According to the U.S. Department of Agriculture (USDA), the current intake is about 1,200 units per day.
Brunswick laboratory in Wareham, Massachusetts, evaluated the power of Saberry® using state-of-the-art tests. The suite of ORAC assays – ORAC, HORAC, NORAC, SORAC and SOAC – are validated tests to measure broad-spectrum antioxidant power. They are recognized as the premier antioxidant tests available today to the industry and are used extensively by leading manufacturers.
The ORAC unit is expressed as micromole per gram or liter. The ORAC analysis provides a measure of the scavenging capacity of antioxidants against “peroxyl radical” which is one of the most common reactive oxygen species (ROS) found in the body.
Saberry® is a leader among water-soluble phytonutrients in terms of broad-spectrum antioxidant activity.

Broad-spectrum antioxidant activity is based on the values of
- ORACTotal – (hydrophilic (H-ORAC) and lipophilic (L-ORAC) – Peroxyl radical absorbance capacity) expressed as trolox equivalent
- HORAC (Hydroxyl radical absorbance capacity) expressed as caffeic acid equivalent
- NORAC (Peroxynitrite radical absorbance capacity) expressed as trolox equivalent
- SOAC (Singlet oxygen absorbance capacity) expressed as alpha-tocopherol equivalent
- SOD (Superoxide dismutase equivalent activity, corresponding to superoxide radical absorbance capacity)
Based on the enhanced antioxidant potential of β-glucogallin over ascorbic acid as evident in the above graph, and the inconsistent presence of ascorbic acid in amla in general, the researchers at Sabinsa concluded that it would be pertinent and more accurate to concentrate on the antioxidant potential of β-glucogallin.
