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:
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:
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.
