Is QuerciSorb SR Kosher?

The Ingredient Breakdown

To determine the kosher status of QuerciSorb SR, we must look beyond the active ingredient and examine the excipients and delivery mechanisms. The primary active component is Solubility enhanced Quercetin derived from Sophora japonica (flower) concentrate. As a plant-derived flavonoid, quercetin itself is inherently kosher. The complexity lies in the delivery matrix.

The product utilizes CyLoc®, a dextrin fiber matrix, and DexKey® release agents. These are patent-pending technologies licensed by Tesseract Medical Research. Both dextrin and the release agents are derived from plant sources (corn or tapioca), ensuring they meet kosher standards without the need for rabbinical supervision regarding grain processing.

Regarding the capsule and flow agents: the capsule is made of hypromellose (plant cellulose), and the flow agent is silicon dioxide (mineral). The sustained-release mechanism relies on calcium laurate, a salt of a fatty acid. While fatty acids can sometimes be animal-derived (tallow), calcium laurate in modern supplements is synthesized from plant oils or mineral sources. There are no flags for dairy, gelatin, or insect-derived shellac in this formulation.

Nutritional Value

QuerciSorb SR is a specialized supplement focused on bioavailability rather than nutritional intake. It contains negligible calories, zero sugar, and no fat. It is designed to be a metabolic support tool rather than a food source.

Because it is a sustained-release formula, it is intended to be taken once daily. It fits easily into strict dietary protocols, including ketogenic, paleo, and low-carb diets, as it does not impact blood glucose levels.
