Flax Oil

Posted on 2005-12-30 20:01:01 in Fatty Acids, Lipids & Oils |

GENERAL DESCRIPTION:

The brown seeds of the flax plant (Linum usitatissimum) were used many centuries ago in Europe to promote healing and combat constipation. Flax oil, which is produced by pressing the seeds, is a rich source of essential fatty acids, including linoleic acid and alpha linoleic acid (ALA).

ROLE IN ANTIAGING:

As well as being a rich source of essential fatty acids, flax oil also contains high concentrations of lignans - antioxidant compounds that may benefit hormone-related conditions. They are also thought to guard against aging, and aid the body in its fight against certain bacteria and viruses. There is some evidence to suggest that lignans may also help to prevent breast, colon, prostate, and skin cancers. However, other research has suggested that the ALA contained in flax oil may increase the risk of breast and prostate cancer. On the whole, the effect of flax oil on cancer risk is inconclusive. Research suggests that flax oil may have several heart-friendly benefits. Several studies have found that the oil can help to lower cholesterol, while others have revealed that it may protect against high blood pressure and angina. The antioxidant properties of lignans present in flax oil may also help to guard against the oxidation of "bad" LDL cholesterol.

DEFICIENCY SYMPTOMS: Not applicable

THERAPEUTIC DAILY AMOUNT:

The most commonly recommended daily dose is 1 tablespoon (15ml) of flax oil. Note: the majority of flax oil capsules contain 1,000mg of oil per capsule, thus to obtain a similar dose to that obtained from 1 tablespoon of oil you would have to taken roughly 14 capsules. Always refer to dosage instructions on packaging.

MAXIMUM SAFE LEVEL: Not established

SIDE EFFECTS/CONTRAINDICATIONS:

There are no known side effects for flax oil if taken as directed, however some people may suffer an allergic reaction. People with bowel obstructions should not take flax oil nor ground flax seed. Some studies suggest that the ALA present in flax oil may increase breast and prostate cancer risk, although other research does not support these claims.
