Flaxseed, called linseed in some countries, is a good source of dietary fiber, omega-3 fatty acids, and lignans. Each of these components may contribute to the health effects of eating flaxseed, but flaxseed oil contains no fiber and very little lignan.
Reliable and relatively consistent scientific data showing a substantial health benefit.
Contradictory, insufficient, or preliminary studies suggesting a health benefit or minimal health benefit.
For an herb, supported by traditional use but minimal or no scientific evidence. For a supplement, little scientific support.
Our proprietary “Star-Rating” system was developed to help you easily understand the amount of scientific support behind each supplement in relation to a specific health condition. While there is no way to predict whether a vitamin, mineral, or herb will successfully treat or prevent associated health conditions, our unique ratings tell you how well these supplements are understood by the medical community, and whether studies have found them to be effective for other people.
For over a decade, our team has combed through thousands of research articles published in reputable journals. To help you make educated decisions, and to better understand controversial or confusing supplements, our medical experts have digested the science into these three easy-to-follow ratings. We hope this provides you with a helpful resource to make informed decisions towards your health and well-being.

For promoting bowel regularity, 1 tablespoon (15 ml) of whole or ground flaxseed is taken one or two times per day, accompanied by a full glass of water. When used to treat other health conditions, it is used in amounts of 30 to 35 grams (1 to 2 ounces) per day.
Although it is not suitable for cooking, flaxseed oil (unlike fish oil) can be used in salads. Some doctors recommend that people use 1 tablespoon (15 ml) of flaxseed oil per day as a supplement in salads or on vegetables to ensure a supply of essential fatty acids. Some conversion of alpha linolenic acid (ALA) to eicosapentaenoic acid (EPA) does occur, and this conversion can be increased by restricting the intake of other vegetable oils.
For those who wish to replace fish oil with flaxseed oil, research suggests taking up to ten times as much ALA as EPA. Typically, this means 7.2 grams of flaxseed oil equals 1 gram of fish oil. However, even if taken in such high amounts, flaxseed oil may not have the same effects as fish oil. But, flaxseed oil will not cause a fishy-smelling burp (a possible side effect of fish oil).
In addition to its presence in flaxseed oil, small amounts of ALA are also found in canola, soy, black currant, and walnut oils. Small amounts of lignans are present in a wide variety of foods of plant origin.
ALA deficiencies are possible but believed to be rare, except in infants who are fed formula that is omega-3 deficient. Lignan is not an essential nutrient, so deficiencies are not possible.
