What is Rutin?

Rutin is a flavonoid glycoside composed of quercetin and the disaccharide rutinose. It’s also called rutoside, quercetin-3-O-rutinoside and sophorin. The name rutin derives from the plant Ruta graveolens (Rue). Historically, rutin has been considered to be part of what was once called vitamin P, but what we now think of as citrus bioflavonoids. While it’s found in a wide variety of plants, including citrus, foods with the highest concentrations of rutin include capers, black olives, buckwheat, and asparagus. The most common use of rutin has been for supporting healthy veins.*

Qualia Rutin Sourcing

Sophorae japonica L. (i.e., Japanese Pagoda Tree) flower extract was selected as an ingredient to provide a standardized amount of rutin. Dried flower buds are used as a starting material to extract rutin, because they can contain as much as 20% rutin.

Rutin Dosing Principles and Rationale

Many flavonoid molecules are part of plants’ protective responses to mild environmental stress. Consuming them tends to produce adaptive functional responses, upregulating pathways that provide stress resistance. Because of this, we don’t think of flavonols like rutin as being “more is better” ingredients. Instead, we think it’s better to use them following hormetic dosing principles (see Neurohacker Dosing Principles). Flavonoids are additive, and often complementary with other polyphenol compounds, so the combination of all polyphenols in a formulation should be considered when determining dosage (not the amount of a single polyphenol molecule in isolation). For these reasons, we use a moderate dose of rutin.*
