Usage
Linseed oil, also known as flaxseed oil, is primarily used as a dietary supplement for its potential health benefits related to its high content of alpha-linolenic acid (ALA), an omega-3 fatty acid. It’s also used topically for skin conditions like eczema and psoriasis. While traditionally used for constipation and wound healing, it is not typically prescribed as a medication for specific medical conditions in modern medical practice. Therefore, a strict pharmacological classification isn’t applicable. ALA, the primary active component, is converted in the body to EPA and DHA, other omega-3 fatty acids that have anti-inflammatory effects.
Alternate Names
- Flaxseed oil
- Linum usitatissimum (scientific name)
- Several brand names exist for commercially available linseed oil supplements.
How It Works
Pharmacodynamics: Linseed oil’s primary active component, ALA, exerts its effects after conversion to EPA and DHA, which have anti-inflammatory properties by influencing eicosanoid production. This leads to potential benefits for cardiovascular health and inflammatory conditions. ALA may also have antioxidant properties.
Pharmacokinetics: Linseed oil is orally ingested, and ALA is absorbed in the intestines. The conversion rate of ALA to EPA and DHA is limited, but still contributes to omega-3 levels. It’s metabolized in the liver and eliminated through various pathways, including renal and hepatic excretion. Specific receptor binding, enzyme inhibition, or neurotransmitter modulation by ALA are not fully characterized.
Dosage
Standard Dosage
Adults: General health and wellbeing: 1-2 tablespoons (15-30ml) or 1000-2000mg of capsules daily, taken with food. The dosage may be adjusted based on individual needs and specific health conditions.
Children: Consult a pediatrician before giving linseed oil to children. Dosage recommendations vary based on the child’s age and health status.
Special Cases:
- Elderly Patients: Standard adult dosage, monitoring for gastrointestinal side effects.
- Patients with Renal Impairment: No specific dosage adjustments indicated, but monitor renal function.
- Patients with Hepatic Dysfunction: No specific dosage adjustments indicated, but monitor liver function.
- Patients with Comorbid Conditions: Use with caution in patients with bleeding disorders, diabetes, or those taking blood thinners or blood pressure medication. Consult with the patient’s physician.
Clinical Use Cases Linseed oil doesn’t have established dosages for specific clinical settings like intubation, surgical procedures, mechanical ventilation, ICU use, or emergency situations. It is not a prescribed medication in these contexts.
Dosage Adjustments Adjustments may be necessary based on patient response and tolerance. Consider factors like gastrointestinal side effects and interactions with other medications.

A: Consult a pediatrician before giving linseed oil to children. Dosage recommendations vary based on age and health status.
Q8: Are there any long-term effects of Linseed Oil use?
A: Limited data is available on long-term effects. Potential for nutrient imbalances with excessive, prolonged use.
Q9: How should Linseed oil be stored?
A: Store in a dark, cool place, preferably in a dark glass bottle, to protect it from heat and light, which can degrade its quality.
A: Ground flaxseed and flaxseed oil are more easily absorbed than whole flaxseeds. Flaxseed oil is better for ALA and ground flaxseed for other benefits like fiber.
