Production description:

    Flaxseed oil is derived from the seeds of the flax plant (Linum usitatissimum, L.). Flaxseed oil and flaxseed contain substances that promote good health. One of these substances is alpha-linolenic acid (ALA), an essential fatty acid that appears to be beneficial for heart disease, inflammatory bowel disease, arthritis, and other health conditions. Flaxseed, in addition to ALA, contains a group of chemicals called lignans that may play a role in the prevention of cancer. Please see the flaxseed monograph for further information on this herbal agent.

    ALA, as well as eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), belongs to a group of substances called omega-3 fatty acids. EPA and DHA are found primarily in fish while ALA is mostly found in flaxseed oil and other vegetable oils. Although similar in structure, the benefits of ALA, EPA, and DHA are not necessarily the same.

    It is important to maintain an appropriate balance of omega-3 and omega-6 (another essential fatty acid) in the diet, as these two substances work together to promote health. These essential fats are both examples of polyunsaturated fatty acids, or PUFAs. Omega-3 fatty acids help reduce inflammation and most omega-6 fatty acids tend to promote inflammation. An inappropriate balance of these essential fatty acids contributes to the development of disease while a proper balance helps maintain and even improve health. A healthy diet should consist of roughly 2 - 4 times more omega-6 fatty acids than omega-3 fatty acids. The typical American diet tends to contain 14 - 25 times more omega-6 fatty acids than omega-3 fatty acids, and many researchers believe this imbalance is a significant factor in the rising rate of inflammatory disorders in the United States.

    Omega-3 fatty acids have been shown to reduce inflammation and help prevent certain chronic diseases such as heart disease and arthritis. These essential fatty acids appear to be particularly important for cognitive and behavioral function as well as normal growth and development.

Uses:
    Clinical studies suggest that flaxseed oil and other omega-3 fatty acids may be helpful in treating a variety of conditions. The evidence is strongest for heart disease and problems that contribute to heart disease, but the range of possible uses for flaxseed oil include:

High cholesterol

    People who follow a Mediterranean diet tend to have an increased high density lipoprotein (also called HDL, or "good") cholesterol level. The Mediterranean diet consists of a healthy balance between omega-3, omega-6, and omega-9 (found in olive oil) fatty acids. It emphasizes whole grains, root and green vegetables, daily intake of fruit, fish and poultry, olive and canola oils, and ALA (from flaxseed, flaxseed oil, and walnuts), along with discouragement of ingestion of red meat and not much use of butter and cream.

    Flaxseed and flaxseed oil have been reported to possess cholesterol-lowering properties in laboratory studies. Human studies have used flaxseed products and measured effects on cholesterol, with mixed results. A recent human study found that dietary flaxseed significantly improved lipid (cholesterol) profile in patients with high cholesterol, and may favorably modify cardiovascular risk factors.

Heart disease

     A diet rich in fruits, vegetables, whole grains, nuts or legumes, and ALA-rich foods may substantially reduces the recurrence of heart disease. One of the best ways to help prevent and treat heart disease is to eat a low-fat diet and to replace foods rich in saturated and trans-fat with those that are rich in monounsaturated and polyunsaturated fats (including omega-3 fatty acids from flaxseed). Evidence suggests that people who eat an ALA-rich diet are less likely to suffer a fatal heart attack. ALA may reduce heart disease risks through a variety of biologic mechanisms, including platelet function (making them less "sticky"), inflammation, blood vessel health, and arrhythmia (irregular heart beat).

    Several human studies also suggest that diets rich in omega-3 fatty acids (including ALA) may lower blood pressure.

Other

    Although further research is needed, preliminary evidence suggests that omega-3 fatty acids may also prove helpful in protecting against certain infections and treating a variety of conditions including autism, ulcers, migraine headaches, preterm labor, emphysema, psoriasis, glaucoma, Lyme disease, systemic lupus erythmatosus (lupus), irregular heart beats (arrhythmias), multiple sclerosis, and panic attacks. Omega-3 fatty acid supplementation may also help to reduce stress and the effects it has on the body.

Dietary Sources:
    Flaxseed oil is obtained from the seed of the flax plant. It contains 50 - 60% omega-3 fatty acids in the form of alpha-linolenic acid (ALA). This amount is roughly double that contained in fish oil. However, ALA must be converted in the body into usable forms. ALA from flaxseed may not have the same benefit as eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) because it is more difficult for the body to efficiently convert ALA to a form of omega-3 fatty acids that it can readily use.

Available Forms:
    Flaxseed oil is available in liquid and softgel capsule forms. Like any oil, flaxseed oil may turn rancid if it is not refrigerated. Flaxseed oil requires special packaging because it is easily destroyed by heat, light, and oxygen. The highest quality flaxseed products are manufactured using fresh pressed seeds, bottled in dark or opaque containers, and processed at low temperatures in the absence of light, extreme heat, or oxygen.

    Be sure to buy flaxseed oil supplements made by reputable companies who certify that their products are free of heavy metals such as lead and mercury.

How to Take It:
    The dosage to prevent and treat disease will vary depending on the amount of fatty acids in the diet and the type of disorder being treated.

Pediatric

    Flaxseed oil may be added to a child's diet to help balance fatty acids. If an infant is breastfed, the mother may ingest oil or fresh ground seed to increase fat content in breast milk. See adult dosage below. Only use flaxseed oil supplements in children under 18 years of age under the supervision of a health care provider.

Adult

    Flaxseed oil: Take 1 - 2 tablespoonfuls daily, or 1 - 2 capsules daily. Flaxseed oil is often used in a liquid form, which contains approximately 7 grams of ALA per 15 mL (1 tbsp), and contains approximately 130 calories.

    As a substitute for fish oil, a dose of 7.2 grams of flaxseed oil is approximately equivalent to 1 gram of fish oil.

Precautions:
    Because of the potential for side effects and interactions with medications, dietary supplements should be taken only under the supervision of a knowledgeable health care provider.

    Flaxseed may slow down the absorption of oral medications or other nutrients if taken at the same time. Try to avoid taking flaxseed at the same time as medications and other supplements.

    People with either diabetes or schizophrenia may lack the ability to convert ALA to EPA and DHA, the forms more readily used in the body. Therefore, those with either condition should obtain their omega-3 fatty acids from dietary sources rich in EPA and DHA.

    Although studies have found that regular consumption of fish (which includes the omega-3 fatty acids EPA and DHA) may reduce the risk of macular degeneration, a recent study including two large groups of men and women found that diets rich in ALA may substantially increase the risk of this disease. More research is needed in this area. Until this information becomes available, it is best for people with macular degeneration to obtain omega-3 fatty acids from sources of EPA and DHA, rather than ALA.

   Similar to macular degeneration, fish and fish oil may protect against prostate cancer, but ALA may be associated with increased risk of prostate cancer in men. More research in this area is needed.

Possible Interactions:
    If you are currently being treated with any of the following medications, you should not use flaxseed oil (alpha-linolenic acid or ALA) or other omega-3 fatty acids without first talking to your health care provider.

    Blood-thinning medications -- Omega-3 fatty acids may increase the effects of blood thinning medications, including aspirin, warfarin (Coumadin), and clopedigrel (Plavix). While the combination of aspirin and omega-3 fatty acids may actually be helpful under certain circumstances (such as in heart disease), they should only be taken together under the guidance and supervision of a health care provider.

    Blood sugar lowering medications -- Taking omega-3 fatty acid supplements may increase fasting blood sugar levels. Use with caution if taking blood sugar lowering medications, such as glipizide (Glucotrol and Glucotrol XL), glyburide (Micronase or Diabeta), glucophage (Metformin), or insulin, as omega-3 fatty acid supplements may increase your need for the medication(s).

    Cyclosporine -- Taking omega-3 fatty acids during cyclosporine (Sandimmune) therapy may reduce toxic side effects, such as high blood pressure and kidney damage, associated with this medication in transplant patients.

    Etretinate and topical steroids -- The addition of omega-3 fatty acids (specifically EPA) to the drug therapy etretinate (Tegison) and topical corticosteroids may improve symptoms of psoriasis.

    Cholesterol-lowering medications -- Following certain nutritional guidelines, including increasing the amount of omega-3 fatty acids in your diet and reducing the omega-6 to omega-3 ratio, may allow a group of cholesterol lowering medications known as "statins," including atorvastatin (Liptor), lovastatin (Mevacor), and simvastatin (Zocor) to work more effectively.

    Nonsteroidal anti-inflammatory drugs (NSAIDs) -- In an animal study, treatment with omega-3 fatty acids reduced the risk of ulcers from nonsteroidal anti-inflammatory drugs (NSAIDs), including ibuprofen (Motrin or Advil) and naproxen (Alleve or Naprosyn). More research is needed to evaluate whether omega-3 fatty acids would have the same effects in people.
