Flax seed oil is also known as linseed oil and is completely edible.
Due to the strong odor and flavor it is only consumed in small amounts and usually taken as a nutritional supplement.
It can be taken in either a liquid or softgel capsule form.
Product storage is important due to its need for refrigeration and inability to withstand heat, light and air.
Its color ranges from clear to yellowish and it can be obtained only from the ripe seeds of the flax plant.
The oil is removed from the seeds by cold pressing and often followed by the process of solvent extraction (changing compounds to liquids).
It is naturally composed of a mixture of triglycerides which includes palmitic, stearic, oleic, linoleic and omega-3 fatty (alpha-linolenic) acids.
Palmitic and stearic acids have been shown to lower cholesterol levels when compared with other saturated fatty acids.
Oleic acid has been shown to be able to slow the progression of a fatal disease known as adrenoleukodystrophy affecting the brain.
It can improve memory and has been linked to the blood pressure reduction effects that exist in olive oil.
Studies performed in mice have shown that adding linoleic acid to the diet of mice can prevent cancer.
It also has positive effects as a dietary supplement on infants that suffer with cystic fibrosis due to their inability to properly absorb fatty acids.
Omega-3 fatty acids (alpha-linolenic) were qualified by the FDA as being supportive for the reduction of coronary heart disease.
Several studies have reported that it has possible effects on a variety of cancers including breast, prostate and colon.
In many cases flaxseed oil can be taken as a substitute for fish oil to gain the benefits of omega-3 however, some medications such as blood thinners prevent individuals from being able to take this particular oil.
There is a possibility that flaxseed can slow down the absorption rate of other medications that are currently being taken as well, so it should not be taken at the same time.
For best results, consult a physician before beginning this or any other nutritional supplements when currently taking medication.
