Flaxseed oil, as the name suggests, is oil from the seed of the flax plant. People sometimes assume that flaxseed oil possesses all the same benefits as flaxseed, but this is not the case. Flaxseed oil does not contain all of the active components found in flaxseed.
How Does Flaxseed Oil Work?
The active component of flaxseed oil is probably alpha-linolenic acid (ALA), an
omega-3 fatty acid that may promote heart health. ALA may reduce inflammation and decrease the ability of platelets to stick together (an important step in forming blood clots).
It's important to note that flaxseed does not contain two of the active compounds found in whole or ground flaxseed -- fiber and
phytoestrogens (plant-based estrogen-like compounds). This is why you cannot assume that flaxseed oil has the same effects on the body as flaxseed.
Is Flaxseed Oil Effective?
There is no convincing evidence that flaxseed oil is effective for most uses
(see Does Flaxseed Oil Work? for more information).

What If I Take a Flaxseed Oil Overdose?
It is not known exactly what to expect from a
flaxseed oil overdose (or even if a flaxseed oil overdose is possible), but it is reasonable to assume that taking too much flaxseed oil may cause the usual side effects of flaxseed oil (but they may perhaps be more severe). Theoretically, a flaxseed oil overdose might increase the risk of bleeding, including dangerous internal bleeding.
Flaxseed Oil: Storage Methods
Refer to the label of your individual flaxseed oil product for information on how to best store flaxseed oil. It is often recommended that flaxseed oil be stored in the refrigerator in a dark bottle (to protect it from light).
