Responses by Dr. Joseph Maroon, a board certified neurosurgeon and team physician to the Pittsburgh Steelers, has become one of the nation’s leading advocates of fish oil and has recently authored the book, “Fish Oil: The Natural Anti-inflammatory”.
I have heard long term use of ibuprofen may be bad for my stomach?
You have heard correctly. Ibuprofen is a class of medication commonly called non-steroidal anti-inflammatories (NSAID). These medications were developed in response to the side effects often seen with steroidal medications, such as cortisone and prednisone, which were some of the first types of drugs used to treat joint inflammation and pain. Steroids have side effects of causing stomach bleeding and ulcers and also bone loss and elevation of blood sugar. Those who developed NSAID believed that they would have fewer side effects but similar effectiveness. The fact is despite there success they have retained many of the side effects seen with steroids.
NSAID work well to reduce inflammatory pain and swelling of joints and other tissue but they also can result in users developing ulcers and stomach bleeding if taken for extended periods. Even more disturbing is that NSAIDs has been shown to delay and hamper healing in all the soft tissues, including muscles ligaments, tendons, and cartilage and perhaps leading to additional injury. The NSAIDs also have been shown to have adverse effects on kidney function. Situations resulting in dehydration, common in athletics or preexisting chronic renal failure or disease, may predispose people to acute renal failure through inhibition of when taking NSAIDs. This became big news recently with some high profile professional basketball players who required kidney transplants which were linked to their use of NSAIDs.
Can natural supplements help occasional backache?
The “natural” products, I presume you are referring to are herbal or dietary supplements that may be effective for back or joint pain due to inflammatory causes. Plant-derived natural preparations have been used for hundreds and even thousands of years to obtain effective pain relief. Dietary supplements and herbals are becoming increasingly popular because of their relatively few side effects.
Many natural products have a similar capacity as the synthetic medications to treat inflammation because they both can function to block the inflammatory pathways that eventually cause pain. The classical, swelling, redness, heat and pain associated with an overworked joint all can be block by natural products in order to promote healing and pain relief. Since ancient times our ancestors have used many different plants preparations to curtail the inflammatory process. The most commonly know is the bark of the willow tree from which aspirin was derived.
One of the best natural products used for pain is the omega-3 fatty acids found in fish oils. As a practicing physician and triathlete I both personally like my patients experience the effects of joint pain and inflammation. I too was hooked on NSAIDs to relieve pain complaints. But I began to experience stomach upset which I directly linked to their use. I turned to a colleague who recommended fish oil and have since found a dramatic relief in my own joint pain and also in that of my patients whom I suggested also use fish oil. Forced by my own skepticism and the pressures of conventional medicine I surveyed over 250 of my patients who were using fish oil and found about 60% where able to stop using their traditional prescription NSAID and only required the fish oil.(1) Since this time I have tried, when ever possible, to recommend omega-3 fish oil as the treatment of choice to relieve joint and spine related pain and discomfort.
Can Omega-3 Fish Oil benefit inflammation in other parts of the body, such as the heart and blood vessels?
The fact is fish oil has properties that can also reduce inflammation not only in joints but also in blood vessels, including the blood vessels in the heart, similar to aspirin, and has been found to in many scientific studies to reduce the incidence of heart disease. If fact if you are traveling in Europe and you are unfortunate enough to suffer a heart attack be glad that in Europe at least when you are discharged from the hospital they will prescribe you to take fish oil supplements for the rest of your life.
In a recent NY Times article, appearing Oct 3, 2006, an interview with an Italian cardiologist related that “it would be considered tantamount to malpractice in Italy to omit fish oil to a patient after a heart attack”. (2) What a difference 2,000 miles makes and also the power of drug companies to push prescription drugs as the best and only way to treat medical conditions.
A study published in 2006 in The Journal of the American Board of Family Medicine found that only 17 percent of family doctors were likely to recommend fish oil to their patients, including patients who had suffered a heart attack. (3) There was a great need, the Italian doctors concluded, to “improve awareness of this important advice.”
What is your general recommendation for the daily amount of Omega-3 Fish oil supplement?
I would recommend using about 1-2 gms of high quality, purified, and concentrated omega-3 fish oil per day for joint pain relief. Make sure you read the bottle to the get the 1-2 gms of EPA/DHA which are the “active” ingredients in fish oil. Currently the American Heart Association recommends taking 1 gm per day of omega-3 supplements as EPA/DHA for those people with heart disease.(4) However, many of the scientific studies evaluating heart disease, elevated blood lipids and hypertension have generally used larger amounts.
What are Essential Fatty Acids (EFAs) and why are they important?
Omega-3 and Omega-6 fatty acids constitute the two families of EFAs. EFAs are considered “essential” because they are needed throughout the human life cycle, cannot be manufactured in the human body, therefore they must be obtained through our diet on a daily basis for optimal health and wellness. The body must receive a constant and balanced supply of EFAs to ensure proper prostaglandin production. Prostaglandins are beneficial hormone-like compounds that affect virtually every system in the body. They regulate pain and swelling, help maintain proper blood pressure and cholesterol levels, and promote fluidity in nerve transmission.
If allergic to fish or on blood thinners you should avoid taking fish oil until you consult with your health care provider.
What are early signs of EFA deficiency?
Joint Pain, Poor Memory, Immune Weakness, Dry Skin, Eczema, Hair Loss, Heart Problems, Reproductive Problems (men and women), Mood Swings, Depression, Poor Circulation and Fatigue.
Where can I get a direct source of EFAs?
Omega-3 fatty acids, EPA and DHA, are found in cold water fish such as sardines, mackerel, anchovies and cod liver. GLA, an Omega-6 fatty acid, is abundant in borage and evening primrose oil.
What type of fish does Nordic Naturals use in their products?
All of Nordic Naturals fish oils come from wild fish sources such as sardines, mackerel, and anchovies
What’s the difference between fish oil and flax seed oil?
Omega-3 fatty acids fall into two major categories: Plant derived (flax seed oil, yielding alpha linolenic acid or ALA) or marine derived (fish oil, yielding both EPA and DHA). The human conversion of ALA to EPA and DHA is somewhat slow and can be inhibited by various conditions such as a diet high in linoleic acid (Omega-6), trans-fatty acids such as fast foods and baked goods, alcohol intake, certain health conditions, and vitamin and mineral deficiencies (B3, B6, C, zinc, magnesium). Fish, on the other hand, is a direct source of EPA and DHA. The general consensus is that only about 15% of ALA converts to EPA, and it may not convert to DHA at all.
How soon will I see results?
It will vary depending on the concentration of the fish oil, your current nutritional state, dosage, and current health. We often will hear that our customers “feel better” and experience “clearer thinking” and “an enhanced well being” within 2 weeks. For better results, we recommend you take EFAs daily for at least two months to evaluate their benefits and reduce your intake of hydrogenated and trans-fats.
Are there any side effects?
Generally, no. Consumers typically report having more energy and a greater mental clarity while taking EFAs. If you experience repeat (burping), your supplements are either rancid or your body may not be manufacturing the fat digestive enzyme, lipase, used to metabolize the oil. If you haven’t ingested fish oils for a long period of time it should take about a week for your body to develop this enzyme.
Is it safe to take EFAs derived from fish? I’ve heard that fish oil contains mercury and other environmental toxins.
Fish oils may contain environmental toxins that accumulates in fish during its life span. Potential toxins can be virtually eliminated given the use of high quality raw materials and a technologically advanced refining process utilizing the very latest distillation technologies. Nordic Naturals fish oils are molecularly distilled utilizing a leading edge enzymatic process, where any potential heavy metals and dioxins are removed. Third party testing document the complete absence of heavy metals and dioxins (where heavy metals are tested down to 25 particles per billion and dioxins down to 0.5 particles per trillion). While Nordic Naturals policy is to test competing products on an ongoing basis to monitor the overall quality level of the fish oil industry, Nordic Naturals has never found a competing product to match its freshness and purity levels.
Do pregnant women need EFAs?
It is especially important for a pregnant or lactating woman to get adequate amounts of DHA in her diet because the baby is drawing upon her supply. DHA is critical for healthy development of the brain, eyes, and nervous system. There is evidence linking a deficiency in Omega-3 fatty acids to an increased risk of premature birth. Some experts recommend that women take 500-600 mg per day during pregnancy and lactation. As with any supplement, it is best to check with your health care professional.
Can we get enough EFAs from the food we eat?
Fish is one of the most abundant sources of EFAs, but Americans simply don’t eat enough fish on a regular basis. Even those who eat fish several times a week aren’t getting enough EFAs because much of the fish consumed today are farm raised (fed a diet of grains instead of fish meal) and lack a significant amounts of EPA and DHA. In addition, there are several factors that can lead to a reduced absorption of EFAs: Age, poor diet, alcohol consumption, low levels of certain vitamins and minerals, some prescription drugs, compromised immune status, and a diet high in trans-fatty acids (fast food, baked goods).
What’s the difference between Good fats and Bad fats?
The “bad” fats are trans-fatty acids and saturated fats from animal products. Trans-fatty acids should be avoided completely, this includes margarine, shortening, and processed foods. Meat and dairy products contain high levels of saturated fat and should be eaten in moderation.
The “good” fats include polyunsaturated Essential Fatty Acids (EFAs). EFAs are considered “essential” because they are needed throughout the human life cycle, cannot be produced in the human body, and therefore must be provided through the diet. Omega-3 and Omega-6 fatty acids constitute the two families of essential fatty acids. Omega-6 fatty acids include corn, soybean, safflower, and sunflower oil. While it is important that your diet include both of these essential fatty acids, it is becoming clear that balance is the key to good health.
What should I look for when purchasing fish oil?
1. Investigate the manufacturing process. How is the fish oil manufactured and what are the manufacturing standards?
2. Smell. Does the fish oil smell fishy? If it smells fishy, the fish oil has most likely been exposed to oxygen and is becoming rancid.
3. Taste. Does the fish oil taste fishy? The freshest fish oils should not taste fishy. Avoid fish oils that have really strong fruit flavor added to them because they are most likely trying to hide the fishy flavor of rancid oil.
What is Pharmaceutical Grade?
Pharmaceutical grade/standard relates to the purity of an oil. Nordic Naturals fish oils are tested, before and after production, for heavy metals, PCBs, and dioxin. The results are documented showing the absence of these environmental toxins. Only a true pharmaceutical grade/standard product will pass these standards. Nordic Naturals products test well below pharmaceutical grade/standard because they are solely based on the Norwegian Medicinal Standard, which is the only true pharmaceutical grade/standard to be revered.
Will EFAs interfere with my medical condition or medications I’m taking?
Check with your health care professional since EFAs can reduce blood viscosity and are not recommended if you are using blood thinners, taking high doses of aspirin, or anticipating surgery.
Can EFAs be taken with other supplements?
Yes, EFAs can be taken with a wide variety of supplements. EFAs are extremely well tolerated, natural, health-promoting, and safe to use every day.
Why doesn’t Nordic Naturals test their products with “consumer labs”?
Consumer labs market themselves as being very objective when in fact they charge $5000 per product test plus an additional charge for a written report. We decided to do our own independent testing with a Third party in the United States and we offer our results to all consumers who request them.
How does the alginate in Nordic Naturals detoxification products bind to environmental toxins?
Nordic Naturals detoxification products contain Fucus and Laminaria algae which has alginate in its cell walls. Alginate is documented to molecularly bind to heavy metals. Therefore, it only binds to heavy metals by molecular weight.
Does alginate interfere with nutrient absorption?
Alginate does not interfere with nutrient absorption because its binding is selective by molecular weight. It does not bind to minerals such as iron, calcium, etc.
