Τα τελευταία χρόνια γίνεται συχνά λόγος για μια σχετικά νέα, αλλά πολλά υποσχόμενη κατηγορία λιπαρών οξέων, τα λεγόμενα ωμέγα 3 λιπαρά οξέα. Πολλά έχουν ακουστεί στα περιοδικά, στις εφημερίδες και στην τηλεόραση για τα ωμέγα 3 λιπαρά οξέα και πολλές είναι οι έρευνες που μπορεί να βρει κανείς για αυτά στη βιβλιογραφία. Επιπροσθέτως, μέσα στα τελευταία 8 χρόνια τα ωμέγα 3 λιπαρά οξέα αξιοποιήθηκαν από τις βιομηχανίες υγιεινών προϊόντων και τις φαρμακοβιομηχανίες για την παραγωγή συμπληρωμάτων διατροφής, αλλά και από τη βιομηχανία τροφίμων για τον εμπλουτισμό προϊόντων ευρείας κατανάλωσης, όπως το ψωμί και το γάλα.
Τι είναι όμως τελικά τα ωμέγα 3 και κατά πόσο αξίζει να ασχολούμαστε τόσο πολύ μαζί τους; Είναι όντως ωφέλιμα για τον οργανισμό μας και αν ναι πως μπορούμε να τα αξιοποιήσουμε σωστά για να προάγουμε την καλή υγεία μας;
Τα ωμέγα 3 λιπαρά οξέα ανήκουν στην κατηγορία των λιπαρών οξέων που δεν μπορεί να παράγει το σώμα μας, άρα πρέπει να τα προσλαμβάνουμε από την καθημερινή μας διατροφή. Τα τρία είδη ωμέγα 3 λιπαρών οξέων που είναι γνωστά είναι το άλφα λινολεϊκό οξύ (ALA) το εικοσαπεντανοϊκό οξύ (ΕPA) και το δεκαεξανοϊκό οξύ (DHA). Το άλφα λινολεϊκό οξύ βρίσκεται στον λιναρόσπορο καθώς και στο φυτοπλαγκτόν και τα φύκη. Τα άλλα δύο είδη λιπαρών οξέων (το εικοσαπεντανοϊκό οξύ και το δεκαεξανοϊκό οξύ) είναι ιχθυέλαια και τα βρίσκουμε σε λιπαρά ψάρια όπως το σκουμπρί, ο σολομός, η ρέγκα, ο φρέσκος τόνος και οι σαρδέλες. Όταν προσλαμβάνουμε άλφα λινολεϊκό οξύ (ALA) από τη διατροφή μας, αυτό μετατρέπεται σε εικοσαπεντανοϊκό οξύ (ΕPA) και δεκαεξανοϊκό οξύ (DHA), τα οποία είναι πιο εύκολα για χρήση από τον οργανισμό μας.
Είναι απαραίτητο να τονίσουμε ότι αυτό που παίζει μεγάλο ρόλο είναι η σωστή αναλογία πρόσληψης των ωμέγα 3 λιπαρών οξέων σε σχέση με τα ωμέγα 6 λιπαρά οξέα, μια άλλη απαραίτητη για τον οργανισμό κατηγορία λιπαρών οξέων που την προσλαμβάνουμε κυρίως από σπορέλαια, όπως το καλαμποκέλαιο, το ηλιέλαιο και το φυστικέλαιο. Αξίζει να κάνουμε ιδιαίτερη μνεία σε ένα από τα ωμέγα-6, λιπαρά οξέα, το Γάμμα Λινολεϊκό Οξύ, (GLA), που βρίσκεται κυρίως στο λάδι οινοθήρα (Evening Primose Oil ή EPO) και στο λάδι μπουράντζας (Borage Oil).
Πράγματι, το GLA, έχει αντιφλεγμονικές, αντιαρθριτικές, αντικαρκινικές και αντιδιαβητικές ιδιότητες, ενώ είναι πολύ σημαντικό για την υγεία και την ελαστικότητα του δέρματος, καθώς και για την υγεία και εμφάνιση των νυχιών.
Έρευνες έχουν δείξει ότι η Μεσογειακή διατροφή που ευνοεί την αυξημένη πρόσληψη φυτικών ελαίων, ξηρών καρπών και οσπρίων και τη μειωμένη πρόσληψη κόκκινου κρέατος, συνδέεται με την σωστή αναλογία πρόσληψης ωμέγα 3 λιπαρών οξέων σε σχέση με τα ωμέγα 6 λιπαρά οξέα. Η σωστή αναλογία πρόσληψης (που είναι 1-4 φορές περισσότερα ωμέγα 6 λιπαρά οξέα σε σχέση με τα ωμέγα 3 λιπαρά οξέα) έχει καρδιοπροστατευτική και αντιθρομβωτική δράση.
Επιπροσθέτως, είναι πλέον γεγονός ότι η αυξημένη πρόσληψη ωμέγα 3 λιπαρών οξέων, είτε μέσω κατανάλωσης 3 μερίδων λιπαρών ψαριών (σολομός, σαρδέλες, ρέγκα ή φρέσκος τόνος) εβδομαδιαίως ή με πρόσληψη κάποιου συμπληρώματος διατροφής πλούσιο σε ωμέγα 3 λιπαρά οξέα οδηγεί μακροπρόθεσμα σε μείωση της κακής (LDL) χοληστερίνης και των τριγλυκεριδίων.
Υπάρχουν ερευνητικές ενδείξεις ότι τα ωμέγα 3 λιπαρά οξέα έχουν αντιυπερτασική δράση και μπορούν να οδηγήσουν σε μείωση του κινδύνου θανάτου από εγκεφαλικό επεισόδιο κατά 50% αν καταναλώνονται σε ποσότητα 1500mg εβδομαδιαίως. Τα άτομα που πάσχουν από ζαχαρώδη διαβήτη μπορούν και αυτά να επωφεληθούν από τα ωμέγα 3 λιπαρά οξέα, καθώς υπάρχουν ενδείξεις ότι η κατανάλωση τους συντελεί στην καλύτερη ρύθμιση της γλυκόζης του αίματος και την αύξηση των επιπέδων της καλής (HDL) χοληστερίνης.
Δεν θα μπορούσαμε να παραλείψουμε την ωφέλιμη δράση των ωμέγα 3 λιπαρών οξέων στους πόνους που οφείλονται στην οστεοαρθρίτιδα, λόγω της συμβολής τους στη μείωση της φλεγμονής στην περιοχή της άρθρωσης. Ακόμα υπάρχουν ενδείξεις ότι τα ωμέγα 3 λιπαρά οξέα συντελούν στην αύξηση των επιπέδων ασβεστίου στα οστά και κατά συνέπεια συντελούν στην προφύλαξη της πυκνότητας των οστών και την μείωση του κινδύνου παρουσίας οστεοπόρωσης.
Έρευνες σε άτομα με διπολική κατάθλιψη και σχιζοφρένια έδειξαν μείωση των συμπτωμάτων και της δοσολογίας των ψυχοφαρμάκων μετά από χρήση συμπληρωμάτων ωμέγα 3 λιπαρών οξέων, παρόλα αυτά χρειαζόμαστε περισσότερα στοιχεία για να προσδιορίσουμε τη δοσολογία των ωμέγα 3 που ενδείκνυται για το βέλτιστο αποτέλεσμα.
Ακόμα η επικουρική δράση των ωμέγα 3 για την ίαση των εγκαυμάτων, τη μείωση της φωτοευαισθησίας από τις ακτίνες UV και τη θεραπεία κατά της ψωρίασης είναι πλέον ευρέως γνωστή, ενώ η προστατευτική τους δράση για ορισμένες μορφές καρκίνου όπως του προστάτη, του στήθους και του λεπτού εντέρου βρίσκεται υπό διερεύνηση.
Τέλος, αξίζει να αναφερθούμε σε ένα λιπαρό οξύ, το ελαϊκό οξύ (ωμέγα -9), το οποίο, μαζί με τα αντιοξειδωτικά του παρθένου ελαιόλαδου, έχει ευεργετικότατη επίδραση στο καρδιαγγειακό σύστημα, ενώ υπάρχουν ενδείξεις ότι μειώνει τον κίνδυνο του καρκίνου, ιδίως του ορθού και του παχέος εντέρου, του στήθος, του προστάτη του παγκρέατος και του ενδομητρίου.
Συμπερασματικά, τα οφέλη των ωμέγα λιπαρών οξέων, ιδίως των ωμέγα 3 λιπαρών οξέων είναι πολλαπλά, για αυτό καλό θα ήταν να τα εντάξουμε στη διατροφή μας, είτε με την πρόσληψη τους από τις τροφές, είτε με τη χρήση διατροφικών συμπληρωμάτων.
Omega-3 fatty acids are considered essential fatty acids: They are necessary for human health but the body can' t make them -- you have to get them through food. Omega-3 fatty acids can be found in fish, such as salmon, tuna, and halibut, other seafood including algae and krill, some plants, and nut oils. Also known as polyunsaturated fatty acids (PUFAs), omega-3 fatty acids play a crucial role in brain function as well as normal growth and development. They have also become popular because they may reduce the risk of heart disease. The American Heart Association recommends eating fish (particularly fatty fish such as mackerel, lake trout, herring, sardines, albacore tuna, and salmon) at least 2 times a week.
Research shows that omega-3 fatty acids reduce inflammation and may help lower risk of chronic diseases such as heart disease, cancer, and arthritis. Omega-3 fatty acids are highly concentrated in the brain and appear to be important for cognitive (brain memory and performance) and behavioral function. In fact, infants who do not get enough omega-3 fatty acids from their mothers during pregnancy are at risk for developing vision and nerve problems. Symptoms of omega-3 fatty acid deficiency include fatigue, poor memory, dry skin, heart problems, mood swings or depression, and poor circulation.
It is important to have a balance of omega-3 and omega-6 (another essential fatty acid) in the diet. Omega-3 fatty acids help reduce inflammation, and most omega-6 fatty acids tend to promote inflammation. The typical American diet tends to contain 14 - 25 times more omega-6 fatty acids than omega-3 fatty acids.
The Mediterranean diet, on the other hand, has a healthier balance between omega-3 and omega-6 fatty acids. Many studies have shown that people who follow this diet are less likely to develop heart disease. The Mediterranean diet does not include much meat (which is high in omega-6 fatty acids) and emphasizes foods rich in omega-3 fatty acids, including whole grains, fresh fruits and vegetables, fish, olive oil, garlic, as well as moderate wine consumption.
Uses:
Clinical evidence is strongest for heart disease and problems that contribute to heart disease, but omega-3 fatty acids may also be used for:
High cholesterol
People who follow a Mediterranean-style diet tend to have higher HDL or “good” cholesterol levels, which help promote heart health. Inuit Eskimos, who get high amounts of omega-3 fatty acids from eating fatty fish, also tend to have increased HDL cholesterol and decreased triglycerides (fats in the blood). Several studies have shown that fish oil supplements reduce triglyceride levels. Finally, walnuts (which are rich in alpha linolenic acid or LNA, a type of omega-3 fatty acid) have been reported to lower total cholesterol and triglycerides in people with high cholesterol levels.
High blood pressure
Several clinical studies suggest that diets or fish oil supplements rich in omega-3 fatty acids lower blood pressure in people with hypertension. An analysis of 17 clinical studies using fish oil supplements found that taking 3 or more grams of fish oil daily may reduce blood pressure in people with untreated hypertension.
Heart disease
One of the best ways to help prevent heart disease is to eat a diet low in saturated fat and to eat foods that are rich in monounsaturated and polyunsaturated fats (including omega-3 fatty acids). Clinical evidence suggests that EPA and DHA (eicosapentaenoic acid and docosahexaenoic acid, the two omega-3 fatty acids found in fish oil) help reduce risk factors for heart disease, including high cholesterol and high blood pressure. Fish oil has been shown to lower levels of triglycerides (fats in the blood), and to lower risk of death, heart attack, stroke, and abnormal heart rhythms in people who have already had a heart attack. Fish oil also appears to help prevent and treat atherosclerosis (hardening of the arteries) by slowing the development of plaque and blood clots, which can clog arteries.
Large population studies suggest that getting omega-3 fatty acids in the diet, primarily from fish, helps protect against stroke caused by plaque buildup and blood clots in the arteries that lead to the brain. Eating at least 2 servings of fish per week can reduce the risk of stroke by as much as 50%. However, high doses of fish oil and omega-3 fatty acids may increase the risk of bleeding. People who eat more than 3 grams of omega-3 fatty acids per day (equivalent to 3 servings of fish per day) may have higher risk for hemorrhagic stroke, a potentially fatal type of stroke in which an artery in the brain leaks or ruptures.
Diabetes
People with diabetes often have high triglyceride and low HDL levels. Omega-3 fatty acids from fish oil can help lower triglycerides and apoproteins (markers of diabetes), and raise HDL, so eating foods or taking fish oil supplements may help people with diabetes. Another type of omega-3 fatty acid, ALA (from flaxseed, for example) may not have the same benefit as fish oil. Some people with diabetes can' t efficiently convert LNA to a form of omega-3 fatty acids that the body can use. Also, some people with type 2 diabetes may have slight increases in fasting blood sugar when taking fish oil, so talk to your doctor to see if fish oil is right for you.
Rheumatoid arthritis
Most clinical studies examining omega-3 fatty acid supplements for arthritis have focused on rheumatoid arthritis (RA), an autoimmune disease that causes inflammation in the joints. A number of small studies have found that fish oil helps reduce symptoms of RA, including joint pain and morning stiffness. One study suggests that people with RA who take fish oil may be able to lower their dose of non-steroidal anti-inflammatory drugs (NSAIDs). However, unlike prescription medications, fish oil does not appear to slow progression of RA, only to treat the symptoms. Joint damage still occurs.
Laboratory studies suggest that diets rich in omega-3 fatty acids (and low in the inflammatory omega-6 fatty acids) may help people with osteoarthritis, although more study is needed. New Zealand green lipped mussel (Perna canaliculus), another potential source of omega-3 fatty acids, has been reported to reduce joint stiffness and pain, increase grip strength, and improve walking pace in a small group of people with osteoarthritis. For some people, symptoms got worse before they improved.
An analysis of 17 randomized, controlled clinical trials looked at the pain relieving effects of omega-3 fatty acid supplements in people with RA or joint pain caused by inflammatory bowel disease (IBS) and painful menstruation (dysmenorrhea). The results suggest that omega-3 fatty acids, along with conventional therapies such as NSAIDs, may help relieve joint pain associated with these conditions.
Systemic lupus erythematosus (SLE)
Several small studies suggest that EPA and fish oil may help reduce symptoms of lupus, an autoimmune condition characterized by fatigue and joint pain. However, two small studies found fish oil had no effect on lupus nephritis (kidney disease caused by lupus, a frequent complication of the disease).
Osteoporosis
Some studies suggest that omega-3 fatty acids may help increase levels of calcium in the body and improve bone strength, although not all results were positive. Some studies also suggest that people who don' t get enough of some essential fatty acids (particularly EPA and gamma-linolenic acid [GLA], an omega-6 fatty acid) are more likely to have bone loss than those with normal levels of these fatty acids. In a study of women over 65 with osteoporosis, those who took EPA and GLA supplements had less bone loss over 3 years than those who took placebo. Many of these women also experienced an increase in bone density.
Depression
Studies have found mixed results as to whether taking omega-3 fatty acids can help depression symptoms. Several studies have found that people who took omega-3 fatty acids in addition to prescription antidepressants had a greater improvement in symptoms than those who took antidepressants alone. However, other studies have found no benefit.
Studies are also mixed on whether omega-3 fatty acids alone have any effect on depression. Depression is a serious illness and you should not try to treat it on your own. See a doctor for help.
Bipolar disorder
In a clinical study of 30 people with bipolar disorder, those who took fish oil in addition to standard prescription treatments for bipolar disorder for 4 months experienced fewer mood swings and relapse than those who received placebo. But another 4-month long clinical study treating people with bipolar depression and rapid cycling bipolar disorder did not find that EPA helped reduce symptoms.
Schizophrenia
Preliminary clinical evidence suggests that people with schizophrenia may have an improvement in symptoms when given omega-3 fatty acids. However, a recent well-designed study concluded that EPA supplements are no better than placebo in improving symptoms of this condition.
Attention deficit/hyperactivity disorder (ADHD)
Children with attention deficit/hyperactivity disorder (ADHD) may have low levels of certain essential fatty acids (including EPA and DHA). In a clinical study of nearly 100 boys, those with lower levels of omega-3 fatty acids had more learning and behavioral problems (such as temper tantrums and sleep disturbances) than boys with normal omega-3 fatty acid levels.
However, studies examining whether omega-3 fatty acids help improve symptoms of ADHD have found mixed results. A few studies have found that omega-3 fatty acids helped improve behavioral symptoms, but most were not well designed. One study that looked at DHA in addition to stimulant therapy (standard therapy for ADHD) found no effect. More research is needed, but eating foods that are high in omega-3 fatty acids is a reasonable approach for someone with ADHD.
Skin disorders
In one clinical study, 13 people with sun sensitivity known as photo dermatitis showed less sensitivity to UV rays after taking fish oil supplements. However, topical sunscreens are much better at protecting the skin from damaging effects of the sun than omega-3 fatty acids. In another study of 40 people with psoriasis, those who took EPA with their prescription medications did better than those treated with the medications alone. However, a larger study of people with psoriasis found no benefit from fish oil.
Inflammatory bowel disease (IBD)
Results are mixed as to whether omega-3 fatty acids can help reduce symptoms of Crohn' s disease and ulcerative colitis, the two types of IBD. Some studies suggest that omega-3 fatty acids may help when added to medication, such as sulfasalazine (a standard medication for IBD). Others find no effect. More studies are needed. Fish oil supplements can cause side effects that are similar to symptoms of IBD (such as flatulence, belching, bloating, and diarrhea).
Asthma
Studies examining omega-3 fatty acids for asthma are mixed. In one small, well-designed clinical study of 29 children with asthma, those who took fish oil supplements rich in EPA and DHA for 10 months reduced their symptoms compared to children who took placebo. However, most studies have shown no effect.
Macular Degeneration
A questionnaire given to more than 3,000 people over the age of 49 found that those who ate more fish were less likely to have macular degeneration (a serious age-related eye condition that can progress to blindness) than those who ate less fish. Similarly, a clinical study comparing 350 people with macular degeneration to 500 without the eye disease found that those with a healthy dietary balance of omega-3 and omega-6 fatty acids and more fish in their diets were less likely to have macular degeneration.
Menstrual pain
In one study of 42 women, they had less menstrual pain when they took fish oil supplements than when they took placebo.
Colon cancer
Eating foods rich in omega-3 fatty acids seems to reduce the risk of colorectal cancer. For example, Eskimos, who tend to have a high-fat diet but eat significant amounts of fish rich in omega-3 fatty acids, have a low rate of colorectal cancer. Animal studies and laboratory studies have found that omega-3 fatty acids prevent worsening of colon cancer. Preliminary studies suggest that taking fish oil daily may help slow the progression of colon cancer in people with early stages of the disease. If you have colorectal cancer, ask your doctor before taking any supplements.
Breast cancer
Although not all experts agree, women who eat foods rich in omega-3 fatty acids over many years may be less likely to develop breast cancer. More research is needed to understand the effect that omega-3 fatty acids may have on the prevention of breast cancer.
Prostate cancer
Population based studies of groups of men suggest that a low-fat diet including omega-3 fatty acids from fish or fish oil help prevent the development of prostate cancer.
Dietary Sources:
Fish, plant, and nut oils are the primary dietary source of omega-3 fatty acids. Eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) are found in cold-water fish such as salmon, mackerel, halibut, sardines, tuna, and herring. ALA is found in flaxseeds, flaxseed oil, canola (rapeseed) oil, soybeans, soybean oil, pumpkin seeds, pumpkin seed oil, purslane, perilla seed oil, walnuts, and walnut oil. Other sources of omega-3 fatty acids include sea life such as krill and algae.
Available Forms:
Both EPA and DHA can be taken in the form of fish oil capsules. Flaxseed, flaxseed oil, fish and krill oils should be kept refrigerated. Whole flaxseeds must be ground within 24 hours of use, so the ingredients stay active. Flaxseeds are also available in ground form in a special mylar package so that the components in the flaxseeds stay active.
Be sure to buy omega-3 fatty acid supplements made by established companies who certify that their products are free of heavy metals such as mercury, lead, and cadmium.
How to Take It:
Dosing for fish oil supplements should be based on the amount of EPA and DHA, not on the total amount of fish oil. Supplements vary in the amounts and ratios of EPA and DHA. A common amount of omega-3 fatty acids in fish oil capsules is 0.18 grams (180 mg) of EPA and 0.12 grams (120 mg) of DHA. Five grams of fish oil contains approximately 0.17 - 0.56 grams (170 -560 mg) of EPA and 0.072 - 0.31 grams (72 - 310 mg) of DHA. Different types of fish contain variable amounts of omega-3 fatty acids, and different types of nuts or oil contain variable amounts of LNA. Fish oils contain approximately 9 calories per gram of oil.
Children (18 years and younger)
There is no established dose for children. Omega-3 fatty acids are used in some infant formulas. Fish oil capsules should not be used in children except under the direction of a health care provider. Children should avoid eating fish that may be high in mercury, such as shark, swordfish, king mackerel, and tilefish.
Adults
Do not take more than 3 grams daily of omega-3 fatty acids from capsules without the supervision of a health care provider, due to an increased risk of bleeding.
• For healthy adults with no history of heart disease: The American Heart Association recommends eating fish at least 2 times per week.
• For adults with coronary heart disease: The American Heart Association recommends an omega-3 fatty acid supplement (as fish oils), 1 gram daily of EPA and DHA. It may take 2 - 3 weeks for benefits of fish oil supplements to be seen.
• For adults with high cholesterol levels: The American Heart Association recommends an omega-3 fatty acid supplement (as fish oils), 2 - 4 grams daily of EPA and DHA. It may take 2 - 3 weeks for benefits of fish oil supplements to be seen.
Precautions:
Because of the potential for side effects and interactions with medications, dietary supplements should be taken only under the supervision of a knowledgeable health care provider.
Omega-3 fatty acids should be used cautiously by people who bruise easily, have a bleeding disorder, or take blood-thinning medications including warfarin (Coumadin) or clopidogrel (Plavix). High doses of omega-3 fatty acids may increase the risk of bleeding.
Fish oil can cause gas, bloating, belching, and diarrhea. Time-release preparations may reduce these side effects, however.
People with either diabetes or schizophrenia may lack the ability to convert alpha-linolenic acid (LNA) to eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), the forms more readily used in the body. People with these conditions should be sure to get enough EPA and DHA from their diets. Also, people with type 2 diabetes may experience increases in fasting blood sugar levels while taking fish oil supplements. If you have type 2 diabetes, use fish oil supplements only under the supervision of a health care provider.
Although studies suggest that eating fish (which includes the omega-3 fatty acids EPA and DHA) may reduce the risk of macular degeneration, a recent study including 2 large groups of men and women found that diets rich in LNA may increase the risk of this disease. Until more information becomes available, people with macular degeneration should get omega-3 fatty acids from sources of EPA and DHA, rather than LNA.
Fish and fish oil may protect against prostate cancer, but LNA may be associated with increased risk of prostate cancer in men. More research in this area is needed.
Some fish may contain potentially harmful contaminants, such as heavy metals (including mercury), dioxins, and polychlorinated biphenyls (PCBs). For sport-caught fish, the U.S. Environmental Protection Agency (EPA) recommends that pregnant or nursing women eat no more than a single 6-ounce meal per week, and young children less than 2 ounces per week. For farm-raised, imported, or marine fish, the U.S. Food and Drug Administration recommends that pregnant or nursing women and young children avoid eating types with higher levels of mercury (such as mackerel, shark, swordfish, or tilefish), and eat up to 12 ounces per week of other fish types.
Buy fish oil from a reputable source that tests to make sure there is no mercury or pesticide residues in its products.
Possible Interactions:
If you are currently being treated with any of the following medications, you should not use omega-3 fatty acid supplements, including eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA), and alpha-linolenic acid (LNA), without first talking to your health care provider.
Blood-thinning medications -- Omega-3 fatty acids may increase the effects of blood thinning medications, including aspirin, warfarin (Coumadin), and clopedigrel (Plavix). Taking aspirin and omega-3 fatty acids may be helpful in some circumstances (such as in heart disease), but they should only be taken together under the supervision of a health care provider.
Diabetes medications -- Taking omega-3 fatty acid supplements may increase fasting blood sugar levels. Use with caution if taking medications to lower blood sugar, such as glipizide (Glucotrol and Glucotrol XL), glyburide (Micronase or Diabeta), glucophage (Metformin), or insulin. Your doctor may need to increase your medication dose. These drugs include:
• Glipizide (Glucotrol and Glucotrol XL)
• Glyburide (Micronase or Diabeta)
• Metformin (Glucophage)
• Insulin
Cyclosporine -- Cyclosporine is a medication given to people with organ transplants. Taking omega-3 fatty acids during cyclosporine (Sandimmune) therapy may reduce toxic side effects, such as high blood pressure and kidney damage, associated with this medication.
Etretinate and topical steroids -- Adding omega-3 fatty acids (specifically EPA) to the drug therapy etretinate (Tegison) and topical corticosteroids may improve symptoms of psoriasis.
Cholesterol-lowering medications -- Following dietary guidelines, including increasing the amount of omega-3 fatty acids in your diet and reducing the omega-6 to omega-3 ratio, may help a group of cholesterol lowering medications known as statins to work more effectively. These medications include:
• Atorvastatin (Liptor)
• Lovastatin (Mevacor)
• Simvastatin (Zocor)
Nonsteroidal anti-inflammatory drugs (NSAIDs) -- In an animal study, treatment with omega-3 fatty acids reduced the risk of ulcers from nonsteroidal anti-inflammatory drugs (NSAIDs). NSAIDs include ibuprofen (Motrin or Advil) and naproxen (Aleve or Naprosyn). More research is needed to see whether omega-3 fatty acids would have the same effects in people.
