Omega-3 - What's
all the fuss?
From the American Heart Association to the President of the
United States, a lot has been said recently about the benefits
of omega-3's. In the early 1980's, researchers noticed that
tribal people native to Greenland had an astoundingly low
incidence of inflammatory conditions like psoriasis, colitis,
and diabetes. A study was conducted and scholars determined
that the secret to the health of these people lay in their
diet, which is rich in coldwater fish and, more importantly,
the omega-3 fatty acids found in these fish. In the intervening
years, omega-3's have been linked with not only reducing the
severity of psoriasis, eczema and other skin conditions, but
a host of health benefits ranging from reducing cholesterol
to combating depression!
Omega-3's are part of a group of essential fatty acids which
our bodies are unable to synthesize on our own. Simply put,
we are unable to produce omega-3's, so they must be acquired
from outside sources. In nutrition, important omega-3's include α-linolenic
acid (ALA), eicosapentaenoic
acid (EPA), and docosahexaenoic
acid (DHA). Both DHA and EPA are commonly found in fish
oils, while good sources for ALA include seeds such as flax and pumpkin, as well as walnuts.
It is also important to understand the relationship between
omega-3 fatty acids and omega-6 fatty acids. Omega-6 fatty
acids are found in cereals, bread, baked goods, and some vegetables
and, when overconsumed, can actually increase inflammation
and allergic response in some individuals. Though some omega-6
is certainly necessary, it is thought that most Western diets
contain far too much of it in relation to omega-3. Omega-3
fatty acids tend to have the opposite effect on the system,
reducing inflammation, and may counter the effects of too
much omega-6 in the body.
A.P. Simopoulos of the Center for Genetics, Nutrition and
Health has found information that suggests that humans evolved
on a diet with a ratio of omega-6 to omega-3 fatty acids of
approximately 1:1. The modern-day ratio is ranges anywhere
from approximately 10:1 to 25:1! This indicates that Western
diets are seriously lacking in omega-3 fatty acids, compared
with the diet on which genetic patterns were established and
humans evolved. Consumption of omega-3 through supplementation
or eating certain plants and fish is known to modulate the
balance of lipid inflammatory mediators, and can thereby make
a valuable contribution in the treatment of inflammatory skin
disorders. Modern nutritional science has developed new insight
into the relation between food intake and health, and consumption
of omega-3 fatty acids appears to be biologically relevant
for optimal skin health.
Omega-3's and skin health
Inflammatory skin conditions such as psoriasis often greatly
improve when the proper amounts and concentrations of essential
fatty acids are consumed. Omega-3 many contribute to reduction
in the number of flare-ups as well as the severity of scaling
and redness. In general, omega-3 supplementation usually improves
skin moisture and appearance, as well as dry skin and eczema.
Numerous studies and trials have been conducted to test
the efficacy of omega-3's on skin health and psoriasis.
Here are just a few that illustrate the promising results
of this amazing fatty acid!
- In a 1998 study conducted by German researchers, psoriasis
sufferers who received injections of omega-3's showed
marked improvement in their condition opposed to those who
received placebo or omega-6's.
- A 1992 double-blind study determined that topical omega-3
fatty acids reduced the severity and density of psoriasis
plaques over a four-week period.
- In 1988, patients asked to take omega-3 supplements over
a ten-week period showed significant improvement in their
psoriasis symptoms, while those taking placebo showed no
change.
The results of these and many other studies clearly demonstrate
the link between skin health improvement and omega-3's. The
scientific community is still trying to find a direct link
between omega-3 fatty acids and psoriasis. Several studies
have actually found little or no improvement from the use
of omega-3. Notwithstanding, most researchers and practitioners
would agree that adding omega-3 to your diet is a wise choice.
When choosing a supplement, it's important that you consider
a high-quality pharmaceutical-grade product such as that contained
in DermaEssentials™.
Additional benefits of omega-3 fatty acids
Scientists hypothesized that DHA and EPA would prove to be
a useful tool in helping reduce inflammatory conditions such
as psoriasis when they started studying the benefits of omega-3's.
As studies continued, their expectations were confirmed, but
they also discovered that omega-3's were beneficial
for a wide range of other afflictions. Heart disease, inflammatory
conditions, and some neurological afflictions also have a
positive response to omega-3!
Inflammatory conditions
Omega-3's are particularly good at reducing inflammation
in the body. A study conducted on patients with intestinal
disorders such as colitis and Crohn's disease found
that subjects taking fish oil supplements required far less
potentially harmful steroids to treat their conditions than
those taking a placebo. Most holistic practitioners are keenly
aware that the state of the intestinal tract directly affects
the state of many other tissues - including skin health.
Heart conditions
Not only do omega-3's have the potential to reduce
inflammation around the heart and in the veins and arteries,
but they have also been shown to significantly diminish the
incidence of heart attacks and strokes when taken as recommended.
Omega-3's relax the arteries and encourage blood to
move more quickly through them. Hypertension can also be reduced,
and omega-3's are also suggested for assistance in lowering
blood pressure! Cholesterol levels are also affected by omega-3
consumption: individuals taking them often experience a drop
in LDL levels and an increase in HDL or "good"
cholesterol levels. The American Heart Association recommends
that when possible, people should include omega-3's
in their diet as a preventative measure against heart disease.
Neurological conditions
Individuals suffering from schizophrenia often have difficulty
processing fatty acids, and frequently show low levels of
DHA and EPA. Omega-3's may also reduce the amount of
interleukin-2, a substance that may cause schizophrenia-like
symptoms in some individuals. Rates of depression in countries
where people regularly consume lots of fish, and therefore
omega-3's, are far lower than those in countries where
lesser amounts are eaten. Recent studies have also linked
omega-3 to a reduction in severity and regularity of attention
deficit disorder in children.
Precautions
If you are taking certain heart medications or suffering
from a bleeding disorder (such as hemophilia or von Willebrand's),
you should not be taking DHA/EPA supplements except under
the advice of a physician. Supplements containing EPA are
not recommended for infants or small children without healthcare
provider surveillance because they can upset the balance between
DHA and EPA during early development. This suggests that pregnant
women should also be cautious about taking fish oil supplements
and clear their use with their OB/GYN or nurse midwife. Fish
oil may be associated with side effects such as abdominal
discomfort and loose stools. In addition, they may lengthen
bleeding time slightly. Those taking blood-thinning medications
should discuss the use of fish oil capsules with their medical
professional. Consumption of DHA/EPA may also increase antioxidant
requirements in the body. Taking extra vitamin E along with
omega-3 may be helpful. Consult your healthcare provider before
adding any new herbs or supplements to your existing medication
regimen.
Adverse effects can include the following:
- Increased levels of vitamins A
- Increased levels of vitamin D (increased levels of vitamin D might actually help psoriasis
and other skin conditions)
- Fishy aftertaste (not observed with enteric-coated
versions)
- Fishy burps (not observed with enteric-coated versions)
- Loose stools
- Nausea (not observed with enteric-coated versions)
- Decreased triglycerides (TG's) and increased low-density
lipoproteins (LDL's), which are cholesterol profile
components
- Increased bleeding time

Should you take omega-3's?
By now you might be wondering, "So why isn't
everyone taking omega-3?" Well, unless an individual
is suffering from a blood clotting disorder or taking certain
heart medications, the answer is, they probably should be!
In the interst of raising awareness for better health, the
Bush administration asked the both the Departments of Health
and Human Services and Agriculture to promote the inclusion
of omega-3's in a healthy diet. The American Heart Association
endorses their use to increase heart health. Whereas DHA is
normally found in breast milk, baby formula-manufacturing
companies are now adding it to infant formulas to promote
increased health in bottle-fed infants.
While the FDA approves the use of omega-3's for improving
health, they have yet to establish RDA's (recommended
daily allowances) for them. Most researchers agree that a
approximately 100-200 mg DHA and 200-400 mg EPA
are sufficient amounts for most adults. But with certain conditions,
individuals may need between 2-4 grams total per day
of combined omega-3's to make an observable difference
in those health concerns, such as a shift in the cholesterol
profile or a reduction in inflammatory conditions like psoriasis.
Most Americans are unable to include cold-water fish such
as salmon, mackerel or sardines in their daily diet, not coming
close to the suggested three times per week. Many of us are
also concerned about high levels of toxins found in the larger
fish species. These issues can be circumvented by taking omega-3's
in the form of a pharmaceutical-grade fish-oil supplement.
Flax seed vs. fish oil
You may have seen or heard that flaxseed oil is a good source
of omega-3's and wonder if it has the same health benefits
as fish oil. Although flax seed does in fact contain omega-3's,
many leading experts still recommend fish oil as the best
source. Plant-based supplements contain ALA, which our bodies
are able to convert to EPA and DHA, but researchers are still
unsure how effectively. In his book The Omega-3 Connection,
Dr. Andrew Stoll explains, "Although the scientific
literature is mixed on this issue, humans may be unable to
convert enough ALA to EPA and DHA to achieve optimal levels
of these long-chain omega-3's." Another problem
with flax oil is its short shelf life. Flax oil needs to be
used quickly or it oxidizes and becomes rancid, a quality
that may have a pro-inflammatory affect. Because of its unstable
nature, flax seed oil does not travel very well. Finally,
most of the research on the positive uses of omega-3's
has focused on the EPA and DHA obtained from fish oil.
The omega-3 in DermaEssentials™ skin care packs
It requires gallons of health-store grade omega-3 fish oils
to concentrate and produce just one gallon of the pharmaceutical-grade
fish oil used in DermaEssentials™ Skin Care Packs. Our program delivers 1320 mg of EPA and 680
mg of DHA each day (just over 2 grams) in the form of four
softgel tablets. Ours is a concentrated marine fish oil -
the highest quality available. Our fish oil has gone
through an extensive molecular distillation process to ensure
purity. The softgel capsules contained in the DermaEssentials™
packets are enteric-coated. Enteric coating is a protective
coating placed around the oral softgel tablet that allows
the omega-3 to reach the intestines without being dissolved
by the stomach's acid first. Dissolving omega-3 in the
small intestine maximizes the body's absorption of omega-3
essential fatty acids. It also cuts down on the fishy aftertaste
and fish burps often associated with marine lipid supplementation.
Further absorption is aided by the digestive enzymes contained
in the DermaEssentials™ formula and use of our DermaDetox™
colon and liver cleansing system.
Pharmaceutical-grade, enteric-coated omega-3 tablets are
priced at two to three times the cost of standard fish oil
supplements (i.e., usually around $15 for 60 softgels at 660
EPA mg and 340 mg DHA, or $30 at the DermaEssential™
levels). Typically, high-grade omega-3 brands (like DermaEssentials™)
have more than double the omega-3 concentration of ordinary
brands.
DermaEssentials™ skin care packs -
Four nutritional formulas in one convenient pack to provide
the nutritional foundation needed to stimulate the healing
process from within. They travel easily, and are designed
to be taken twice daily with meals.
- Multi-Minerals and Vitamins (6 per day)
- Opti-EPA Omega-3 Fish Oils (4 per day)
- Digestive Enzymes (2 per day)
- Multi-Probiotic (2 per day)
In an independent review of 500 supplement products available
in the United States and Canada, the DermaEssentials™
base nutritional formula (prior to the addition of EPA/DHA
- concentrated marine fish oil, digestive enzymes, and
the 4 billion multiprobiotics included in our full packet) ranked higher than 489 other formulas on
14 criteria.

Radiant
skin begins with your diet! You may
be surprised to learn that what you eat can dramatically affect
the condition of your skin. Perhaps you remember a friend
or family member warning you about chocolate and French fries
causing acne back in high-school, and dismissed it as myth.
In fact, they weren't that far off-base with their warnings!
Vitamin
D-3 and the skin. Although there is currently
no proven cure for psoriasis, recent research indicates there
are numerous health benefits to vitamin D supplementation,
supporting relief from many inflammatory ailments and medical
conditions. We believe this includes psoriasis!
Candida. If you were able to gather up and weigh the bacteria in your
digestive system, researchers estimate the total would be
about four pounds! Under ideal circumstances, friendly microorganisms
line our intestines and perform many functions that aid in
digestion, benefitting the overall health of the body.
