high quality of proteins, vitamins, minerals and lipids, besides
being the largest source of w-3 polyunsaturated fatty acids,
especially the eicosapentaenoic acid (EPA) and docosahexaenoic fatty
acids (DHA), which bring several benefits to human population.(Belda
and Pourchet — Compos, 1991). The various types of fish which can

halibut, herring, sea bass, sardines, swordfish, oysters, albacore
tuna, blue fin tuna, yellow fin tuna, turbot, pilchards, anchovies

tuna, herring, mackerel, sardines, lake trout and salmon. The type of
fish used and the purity standards followed in refining the oil
govern the quality of fish oil.
health benefits of fish oil
to the American Heart Association (AHA), clinical trials have proved
that omega 3 is effective in reducing the incidence of cardiovascular
diseases (CVD). Fish oil, which is abundant in omega-3, therefore,
reduces the risk of heart diseases and heart arrhythmias. It lowers
the levels of LDL cholesterol, which is bad cholesterol, and
increases the HDL levels, which is good cholesterol. Fish oil
prevents accumulation of triglycerides and further reduces the levels
of excess triglycerides. Preliminary research has also shown that
fish oil can be used for preventing atherosclerosis in coronary
patients. Thus fish oil is effective in treating heart strokes and
regular usage of fish oil can help avoid numerous sudden cardiac
oil also aids in weight loss process. Fish oil improves the efficacy
in reducing weight.
is believed that fish oil has the ability to improve
along with reducing triglyceride and serum cholesterol levels.
is believed that regular consumption of fish oil aids in increasing
your immunity there by enabling you to resist incidence of common
diseases such as cold, cough and flu. Omega three fatty acids present
in fish oil benefit the immune system by effecting cytokines and
eicosanoids present in our body. Fish oil has the potential to
enhance the immune system of humans. Fish oil is also beneficial to
patients suffering from lupus, which is a disease characterized by
the attacks of immune system of the body on various organs and
tissues. Fish oil helps in reducing the pain and inflammation that
may occur in joints, eyes, kidney, heart, blood vessels, lungs,
nerves, etc. It also helps in reducing associated fever,
skin rashes and fatigue.
oil has anti inflammatory properties; therefore, it is effective in
reducing inflammation in blood and tissues. Regular consumption of
fish oil supplements, tablets, pills and capsules is helpful to those
suffering from chronic inflammatory diseases. Fish oil is effective
in treating gastrointestinal disorders, sprue, short bowel syndrome
and inflammatory bowel disease (IBD) including Crohn's Disease and
ulcerative colitis, which are typical disorders of the intestine.
Patients suffering from Crohn's disease find it difficult to absorb
vitamins, fats and essential supplements. Fish oil supplements are an
effective diet for such patients. In ulcerative colitis, fish oil
prevents the accumulation of leukotriene on the colon. It should be
noted that the anti inflammatory properties of fish oil are limited
to reducing inflammation. Fish oil provides little effect in
oil is useful in treating arthritis, rheumatism, Raynaud's symptoms
and similar conditions. Usage of fish oil can help reducing the
dosage of NSAIDs (non-steroidal anti-inflammatory drugs). The Royal
Adelaide Hospital, Australia,
Australia have reported that large quantities of fish oil have shown
positive effect on the treatment
of arthritis. In case
of osteoarthritis, fish oil can be helpful in reducing the impact of
enzymes that destroy cartilages. However, since the dosage of fish
oil required for desirable effect in the improvement of a patient is
unknown, the Arthritis
Center, Department of
Rheumatology, John Hopkins University, considers including omega 3
fatty acids and fish oil in the treatment of arthritis as
to the presence of Omega 3 fatty acids, fish oil is good for
relieving depression, sadness, anxiety, restlessness, mental fatigue,
stress, decreased sexual desire, suicidal tendencies and other
nervous disorders. Fish oil can be useful in mood stabilizing and
treating bipolar disorders. No wonder, it has been found that
countries where fish is eaten often have low
incidence of depression.
conducted on prisoners
has shown that when prisoners were fed with sea food
containing higher amount of omega three fatty acids, there was a
significant drop in the homicide rate.
oil is one of the best sources of essential fatty acids including EPA
and DHA, it helps in Alzheimer disease. Research
conducted at the University of California
at Los Angeles (UCLA) validates the usefulness of fish oil as a
possible remedy for the disease. The Alzheimer's
fish containing higher content of omega three fatty acids to patients
as it acts as a protective diet during Alzheimer disease and
is well known that fish oil is good for its ability to improve
vision. It also helps in avoiding age related macular degeneration.
Eye Institute at the
National Institute of Health, US, plans to conduct a nation-wide
study to evaluate the effect of fish oil in treating macular
degeneration. This study will provide strong scientific evidence to
the benefits of fish oil for eye care, thereby enabling government
agencies and physicians to strongly recommend fish oil for macular
oil helps in improving the condition of poor and dry
skin by making it
shinny and glowing. It is useful in treating various skin problems
such as eczema,
psoriasis, itching, redness of skin, skin lesions, and rashes. In
case of psoriasis, the EPA present in fish oil restricts the growth
of pro-inflammatory agents by producing arachidonic acid. Fish oil
can also be applied topically to obtain relief from psoriasis.
Regular intake of fish
oil capsules helps in
reducing loss of moisture from the skin. It is also claimed by some
people that fish oil helps in preventing sunburns.
oil is effective for acne as well. EPA is known to inhibit androgen
formation. Androgen can affect the formation of sebum in hair

cancer. Fish oil
supplements can also be helpful to patients suffering from cancer
II diabetic patients are more prone to cardio vascular diseases such
as coronary heart disease, atherosclerosis, and stroke. As mentioned
above, fish oil is helpful in treating various heart problems.
conducted at the University of Oxford, UK,
has proved that fish oil is useful in reducing triglyceride levels in
conducted on boar has
shown that when male boars are fed with diet containing fish oil, the
quality of the sperm is enhanced. After ejaculation, the sperms have
increased survival against lipid peroxidative attacks in the female
genital tract, thereby increasing the chances of conception. On the
other hand, similar animal
studies have shown
inhibition in the synthesis of prostaglandin E and prostaglandin F,
which are produced in large quantities by human seminal vesicles. The
research found no impact in the count and mobility of sperm.
oil helps maintain a good luster of the hair. Omega three has hair
growing properties as it provides nourishment to the follicles. It
therefore aids in faster development of hair and preventing hair
loss. A good supply of
proteins is also necessary for hair growth. Since most fish varieties

oil and vitamins
A and Vitamin D:
Fish oil, especially the one obtained from liver such as the cod
liver oil, is a rich source of vitamin A and vitamin
D. However, excessive dosage of cod liver oil can lead to Vitamin
toxicity, accumulation of excessive vitamins in the body, which can
cause side effects.
There are various beliefs surrounding fish oil and vitamin
oil undergoes oxidation and can become rancid, leading to formation
of free radicals. Addition of antioxidants such as vitamin E to fish
oil can help prevent the formation of these free radicals.
dosage of fish oil leads to reduction of Vitamin E in the human
body. This loss of vitamin E should be supplemented with external
vitamin E supplements.
combination of fish oil and vitamin E can have added benefit in the
treatment of many cancers and heart diseases, than if they are used
research has been carried out which prove the above beliefs; however,
these need to be substantiated with detailed research before drawing
strong conclusions on the use of fish oil and vitamin E.
concluded that fish nutraceuticals are destined to play an important
role in future therapeutic developments and their success will be
governed by control of purity, safety and efficacy without inhibiting
