What Is Flaxseed Extract (SDG)?
Flaxseed (Linum usitatissimum), also known as linseed or common flax, is the richest known dietary source of plant lignans — containing 75 to 800 times more lignans than other plant foods. The primary active compound in Flaxseed Extract is Secoisolariciresinol Diglucoside (SDG), a glycosylated lignan that is metabolized by intestinal bacteria into two biologically active mammalian lignans: enterodiol (END) and enterolactone (ENL).
This gut microbiome-dependent conversion is central to flaxseed extract’s mechanism of action. Enterodiol and enterolactone are structurally similar to endogenous estrogens, giving SDG its well-documented phytoestrogenic properties — making it particularly valuable for women’s health formulations.
For supplement manufacturers, standardized Flaxseed Extract (SDG 20%–60%) provides consistent, measurable active content that whole flaxseed cannot, making it the preferred ingredient for capsule, tablet, and functional food formulations.
Clinical Evidence & Key Benefits
Women’s Health & Menopause Support
Flaxseed Extract SDG is one of the most clinically validated phytoestrogen ingredients for menopausal and perimenopausal symptom relief. A randomized controlled trial published in Cureus (2024) demonstrated that flaxseed supplementation significantly reduced menopausal symptoms compared to placebo (p<0.001), with enterodiol and enterolactone levels considerably higher in the supplemented group. A separate 6-month RCT involving 90 menopausal women confirmed significant reductions in the Kupperman Index (hot flashes, insomnia, joint pain) with no adverse estrogenic effects on endometrial thickness. As highlighted at Vitafoods Europe 2026, women’s health is the fastest-growing supplement category globally — and Flaxseed Extract SDG is a cornerstone ingredient in this space.
Cardiovascular Health
SDG metabolites have demonstrated cardiovascular protective effects across multiple studies, including reducing total and LDL cholesterol, lowering blood pressure, decreasing oxidative stress and inflammation, and supporting overall heart health. A comprehensive PubMed review identified that a dose of at least 500mg SDG per day for approximately 8 weeks produces positive effects on cardiovascular risk factors in human patients.
Gut Health & Microbiome Support
Flaxseed Extract supports gut health through two mechanisms: its fiber content acts as a prebiotic supporting beneficial bacteria, and SDG conversion to active lignans is itself dependent on a healthy gut microbiome — creating a bidirectional relationship between flaxseed supplementation and gut health. This aligns directly with Vitafoods Europe 2026’s dominant theme of gut health as a total-body wellness platform.
Antioxidant & Anti-Inflammatory Protection
SDG and its metabolites demonstrate significant antioxidant activity, reducing oxidative stress markers and inflammatory pathways. A 2022 placebo-controlled crossover trial published in Nutrients identified 1,450 differentially expressed genes in participants following SDG supplementation, confirming measurable effects on inflammation and cellular protection pathways.
Skin Health
Flaxseed Extract’s combination of omega-3 fatty acids, lignans, and antioxidants supports skin barrier function, hydration, and anti-inflammatory protection — making it relevant for both nutricosmetic supplement formulations and topical skin care applications.
Industry Applications
Flaxseed Extract SDG is used across multiple product categories:
Nutraceuticals & Dietary Supplements: Capsules and tablets for women’s health, menopause support, cardiovascular health, and antioxidant formulations.
Functional Foods & Beverages: Health bars, protein powders, functional beverages targeting women’s wellness.
Cosmetics & Skin Care: Nutricosmetic formulations targeting skin hydration, barrier support, and anti-aging.
Pharmaceutical: Formulations targeting menopausal symptoms, cardiovascular risk factors, and hormonal balance.
