# Atasi (Linum usitatissimum) **Canonical URL:** https://ingredients.hermeticasuperfoods.com/ingredients/atasi **Data Source:** Hermetica Superfoods Ingredient Encyclopedia **Updated:** 2026-03-20 **Evidence Score:** 2 / 10 **Category:** Ayurveda **Also Known As:** Linum usitatissimum, Flaxseed, Linseed, Common flax, Alsi, Jawas, Tisi, Flax ## Overview Atasi (Linum usitatissimum) is an Ayurvedic herb containing high concentrations of alpha-linolenic acid (42.97-61.06%) and lignans. These compounds provide [antioxidant activity](/ingredients/condition/antioxidant) through radical scavenging and support [cardiovascular health](/ingredients/condition/heart-health) via omega-3 fatty acid pathways. ## Health Benefits • [Antioxidant activity](/ingredients/condition/antioxidant): In vitro studies show dose-dependent inhibition of superoxide, hydroxyl radicals, and H2O2 (evidence quality: preliminary) • Omega-3 fatty acid source: Seeds contain 42.97-61.06% alpha-linolenic acid, supporting [cardiovascular health](/ingredients/condition/heart-health) (evidence quality: traditional use) • Lignan content: Contains 610-1300 mg/100g of secoisolariciresinol diglucoside (SDG), a phytoestrogen compound (evidence quality: compositional analysis only) • [Anti-inflammatory](/ingredients/condition/inflammation) effects: Traditional Ayurvedic use for inflammation management (evidence quality: traditional use only) • Digestive support: Historically used as a demulcent and for constipation relief due to 15% viscous matter content (evidence quality: traditional use) ## Mechanism of Action Alpha-linolenic acid from atasi converts to EPA and DHA via delta-6 and delta-5 desaturase enzymes, supporting anti-[inflammatory pathway](/ingredients/condition/inflammation)s. Lignans undergo bacterial conversion to enterolactone and enterodiol, which exhibit [antioxidant activity](/ingredients/condition/antioxidant) by scavenging superoxide and hydroxyl radicals. The omega-3 content modulates prostaglandin synthesis and inflammatory mediator production. ## Clinical Summary In vitro studies demonstrate dose-dependent [antioxidant activity](/ingredients/condition/antioxidant) with inhibition of superoxide, hydroxyl radicals, and hydrogen peroxide. Chemical analysis confirms alpha-linolenic acid content ranging from 42.97-61.06% in seeds. No controlled human trials specifically examining atasi have been published. Current evidence remains at preliminary stages with traditional use supporting [cardiovascular](/ingredients/condition/heart-health) applications. ## Nutritional Profile Atasi (Linum usitatissimum) seeds are nutritionally dense with the following approximate composition per 100g: Macronutrients - Protein: 18-30g (rich in glutamic acid, arginine, and aspartic acid; bioavailability moderate due to presence of trypsin inhibitors); Total Fat: 42-45g (predominantly polyunsaturated); Carbohydrates: 28-34g; Dietary Fiber: 27-28g (comprising soluble mucilage ~20-40% and insoluble cellulose/hemicellulose fractions). Fatty Acid Profile - Alpha-linolenic acid (ALA, omega-3): 42.97-61.06% of total fatty acids; Linoleic acid (omega-6): 14-17%; Oleic acid (omega-9): 18-20%; Palmitic acid: 5-7%; Stearic acid: 3-4%. Bioactive Compounds - Secoisolariciresinol diglucoside (SDG): 610-1300 mg/100g (primary lignan; converted by gut microbiota to enterodiol and enterolactone, bioavailability dependent on [microbiome](/ingredients/condition/gut-health) composition); Cyanogenic glycosides (linamarin, linustatin): 200-350 mg/100g (reduced significantly by heat processing). Vitamins - Thiamine (B1): 1.6 mg/100g; Pyridoxine (B6): 0.47 mg/100g; Folate: 87 mcg/100g; Vitamin E (alpha-tocopherol): 0.31 mg/100g. Minerals - Magnesium: 392 mg/100g; Phosphorus: 642 mg/100g; Calcium: 255 mg/100g (bioavailability limited by phytic acid content of 2-3%); Iron: 5.7 mg/100g (non-heme; absorption reduced by phytates); Zinc: 4.3 mg/100g; Potassium: 813 mg/100g. Bioavailability Notes - Ground/milled seeds significantly improve ALA and lignan bioavailability compared to whole seeds; phytic acid (2-3 g/100g) chelates divalent minerals reducing their absorption; mucilage fiber slows gastric emptying and glucose absorption; ALA conversion to EPA/DHA in humans is limited (estimated 5-10% to EPA, <1% to DHA). ## Dosage & Preparation Traditional Ayurvedic dosages include: Churna (powder) 3-6 g daily; Oil 5-15 ml daily; Kalka (paste) 3-6 g daily. No clinically studied dosage ranges or standardization protocols are available in the scientific literature. Consult a healthcare provider before starting any new supplement. ## Safety & Drug Interactions Generally recognized as safe when consumed as flaxseed in normal dietary amounts. May interact with anticoagulant medications due to omega-3 content affecting bleeding time. High fiber content may delay absorption of oral medications if taken simultaneously. Pregnancy and lactation safety requires consultation with healthcare providers due to limited safety data. ## Scientific Research The research dossier reveals a notable absence of human clinical trials, RCTs, or meta-analyses for Atasi (Linum usitatissimum). While reviews mention general [antioxidant](/ingredients/condition/antioxidant) and antibacterial activities demonstrated in vitro, no study designs, sample sizes, or clinical outcomes are detailed, and no PubMed PMIDs are provided. ## Historical & Cultural Context Atasi has been used for centuries in Ayurveda for treating [inflammation](/ingredients/condition/inflammation), constipation, and skin disorders, with references found in classical Sanskrit texts. The seeds, oil, and flowers have all been utilized medicinally, establishing it as one of 230 species in the Linum genus, though L. usitatissimum remains the most economically significant. ## Synergistic Combinations Fish oil, Turmeric, [Probiotic](/ingredients/condition/gut-health)s, Psyllium husk, Evening primrose oil ## Frequently Asked Questions ### What is the omega-3 content in atasi seeds? Atasi seeds contain 42.97-61.06% alpha-linolenic acid (ALA), making them one of the richest plant sources of omega-3 fatty acids. This ALA content supports cardiovascular health through anti-inflammatory pathways. ### How does atasi provide antioxidant benefits? Atasi exhibits dose-dependent antioxidant activity by scavenging superoxide and hydroxyl radicals and inhibiting hydrogen peroxide formation. The lignans convert to enterolactone and enterodiol, which provide cellular protection against oxidative stress. ### Can atasi interact with blood thinning medications? Yes, atasi may enhance the effects of anticoagulant medications like warfarin due to its high omega-3 content. The alpha-linolenic acid can affect bleeding time and platelet aggregation, requiring medical supervision. ### What is the difference between atasi and regular flaxseed? Atasi refers specifically to Linum usitatissimum used in Ayurvedic medicine, while flaxseed is the common name for the same plant. Both contain identical omega-3 fatty acids and lignans but may differ in preparation methods. ### How much atasi should be taken daily for benefits? No standardized dosage exists for atasi supplements due to limited clinical research. Traditional Ayurvedic practices and flaxseed studies suggest 1-2 tablespoons of ground seeds daily, but consultation with healthcare providers is recommended. ### Is atasi safe to take during pregnancy and breastfeeding? While atasi seeds are traditionally consumed as food, high-dose supplementation during pregnancy should be discussed with a healthcare provider due to limited safety data and the phytoestrogen content (lignans) that may affect hormonal balance. Moderate dietary amounts of atasi are generally considered safe, but breastfeeding women should consult their doctor before taking concentrated supplements to ensure safety for the infant. ### What is the most effective form of atasi — whole seeds, ground, or oil? Ground atasi seeds offer superior bioavailability compared to whole seeds, as grinding breaks down the seed coat and increases lignan and nutrient extraction during digestion. Atasi oil provides concentrated omega-3s but lacks the fiber and lignans found in seeds, making ground seeds the most comprehensive form for obtaining all active compounds. ### Does atasi contain compounds that mimic estrogen, and who should be cautious? Yes, atasi contains lignans (secoisolariciresinol diglucoside/SDG) that function as phytoestrogens and are metabolized into enterolignans in the body. Individuals with hormone-sensitive conditions such as estrogen-dependent breast cancer, uterine fibroids, or endometriosis should consult their oncologist or healthcare provider before taking atasi supplements in therapeutic amounts. --- *Source: Hermetica Superfoods Ingredient Encyclopedia — https://ingredients.hermeticasuperfoods.com* *License: CC BY-NC-SA 4.0 — Attribution required.
