Lignanrich

Lignanrich is a branded term used to describe a lignan-rich plant extract marketed as a dietary supplement or functional ingredient. It denotes products standardized to contain elevated levels of lignans, a family of plant polyphenols known for phytoestrogen activity and antioxidant properties. Lignanrich formulations are typically derived from seeds such as flaxseed (which provides secoisolariciresinol diglucoside, SDG) and sesame seeds (which supply lignans including sesamin and episesamin). The manufacturing process generally involves solvent extraction and purification, followed by analytical standardization to a defined lignan content, expressed as a percentage of total lignans or SDG equivalents.

Lignanrich is used as an ingredient in capsules, powders, or fortified foods. It is promoted for its potential health effects associated with lignans, including antioxidant activity and modulation of hormone metabolism. However, evidence from clinical studies is mixed, and no definitive health claims are established. Consumers are advised that lignan-rich products are supplements, not medicines, and should be used as part of an otherwise balanced diet.

Safety and regulation: In many jurisdictions, lignanrich products are regulated as dietary supplements or nutraceuticals. Labels may disclose total lignan content and primary lignans, with warnings for individuals with hormone-sensitive conditions, pregnancy, or those taking hormone therapies. Interactions with certain medications have been discussed in the scientific literature, but guidance varies by country. As with other supplements, quality varies by producer, and third-party testing can help verify content and purity.
