Why Is Flaxseed Oil Taken in Doses of 1000mg?

Although many flaxseed oil supplements come in 1000 milligram doses, there is not enough scientific research to support any recommended dose for flaxseed oil as of 2015, according to the University of Maryland Medical Center. Patients who want to take flaxseed oil supplements should consult with a doctor to determine the appropriate dose based on age, overall health and underlying medical conditions, as WebMD explains.

Derived from the seeds of the flax plant, flaxseed oil contains omega-3 and omega-6 fatty acids, as detailed by the University of Maryland Medical Center. Although the omega-3 fatty acids found in flaxseed oil are similar to those found in fish oil, research is limited regarding whether flaxseed oil imparts the same health benefits as fish oil. People use flaxseed oil in relation with a variety of medical conditions, including high cholesterol, heart disease, Sjogren's syndrome, constipation and cancer.

Additionally, some individuals use the supplement for weight loss. Other uses include those for helping with diabetes, attention deficit-hyperactivity disorder and high blood pressure, explains WebMD.

Because flaxseed oil may interact with other medications, patients should consult a doctor before taking this supplement, according to the University of Maryland Medical Center. Flaxseed oil can increase the effects of certain blood thinners and increase fasting blood glucose levels. Flaxseed oil may also prevent the body from absorbing other medications taken at the same time as the supplement.
