Fish Oil Safety Leaves Arthritis Consumers on Hook--
FDA Cites Supplement Makers for Violations

Fish oil safety violations continue to cast a wide net that places consumers of omega-3 products for arthritis and other issues in a kettle of fish.  Alarming percentages of failed quality and safety inspections by dietary supplement makers, including producers of adulterated fish oil, waves a red flag. Discoveries of PCBs in some fish oil products on market shelves threatens consumer trust....

In a seven-year period, nearly two-thirds of all supplement companies inspected failed to pass the most elementary of the industry’s safety guidelines.  From 2010 through 2016, government inspectors found an average of 65.3% of dietary supplement makers in non-compliance of industry safe-manufacturing rules.1,2 

Industry watchdogs have long been critical of the looseness of the current Good Manufacturing Practices (cGMP) safety regulations enforced by the Food & Drug Administration (FDA).   Limited resources restrict the agency to inspect only a fraction of 13,000 registered supplement facilities annually.  In spite of lax statutes, most manufacturers fall short of safety and purity aspects during facilities inspections.  During fiscal year 2016, FDA conducted 583 inspections that yielded 362 non-compliance Form 483 letters, a failure rate of 62%.1,3 . 

Failed inspections frequently address supplement problems across all brands in a manufacturer’s product line. Many omega-3 supplement makers also market other health related compounds

Fish oil safety issues exposed in FDA warning letters and recalls

Non-compliance companies are required to reply with corrective action plans for the observed infractions for each of the products named. When these offenses are reviewed by higher FDA officials, some are 

evaluated as serious violations.  In such cases, the agency issues Warning Letters, formal notifications that call for prompt reform by the maker.  See the section below titled Fish oil safety violations cited in FDA Warning Letters for actual examples.  In 2016, FDA issued 61 Warning Letters.1,3 Some serious enforcement situations result in supplement recalls.3

After a dietary supplement, such as one that contains omega-3, for example, enters the stream of commerce, the FDA may recall the product to ensure fish oil safety if it is “adulterated” or “misbranded.” A product is considered adulterated if it contains unlisted ingredients or is not prepared or packaged in accordance with manufacturing rules.  It is misbranded if its labeling is false or misleading. 

The government has enforced more than 600 supplement recalls just for supplements “spiked” with hidden pharmaceuticals since the full implementation of the cGMP in 2010.4

Dietary supplements, which are sold without prescriptions and include fish oil omega-3 products, have mushroomed into a $37 billion industry with as many as half of American adults using them. But critics argue than many supplements are ineffective or dangerous and that federal oversight of the industry is too lax.  Supplements cause more than 20,000 emergency room visits annually.4

Why exploding growth of supplement industry affects fish oil quality

Consumers in the United States spend about $1.2 billion annually for fish oil pills and related supplements, according to the Washington 2015. Many studies point towards the benefits of omega-3 fatty acids for heart health, as well as for rheumatoid arthritis and health benefits for several other issues.  There are 200 million dietary supplement consumers in the U.S., according to Stephen Ostroff, M.D., Acting Commissioner of the FDA in 2016. 5,6,7,8 

Dietary supplements are classified as food, not drugs. Based on the nomenclature in which FDA publishes yearly Inspectional Observation Summaries it’s difficult to determine how many Form 483 citations are dietary supplements (not food-related). By the same token, recalls that are adulterated with hidden pharmaceuticals are not listed under the food category, but under the drug category, as an unapproved drug, sometimes difficult to identify it was originally manufactured as a dietary supplement. One cannot in good faith argue that omega-3 manufacturers fail fish oil safety regulations at approximately the same percentage as supplement makers of other products. But research turns up many examples where omega-3 fish oil safety may have been compromised for unwary consumers attempting to relieve symptoms of arthritis and other health issues.

Actual FDA Warning Letters to violators of fish oil safety

The following FDA warning letter examples characterize serious fish oil safety compromises for quality and manufacturing violations, nearly all for adulterated omega-3 supplements:

  • On January 24, 2018, FDA issued a warning letter to Young Health Products LLC following a website review in November 2017 and again in January 2018. Inspectors found many of the company’s products, including Flax Seed & Omega 3-6-9 Fish Oil supplement promoted as an anti-inflammatory for pain of arthritis and many other conditions to be drug claims, not generally recognized as safe and effective and therefore classified as “new drugs” in violation of cGMP.9. 
  • On December 19, 2017, FDA issued a warning letter to Maine Natural Health, Inc. following a facility inspection which found some of the company’s products, including Peppermint SO3+D3 Fish Oil, promoted for arthritis and other conditions, adulterated in violation of cGMP fish oil safety regulations.10. 
  • On May 22, 2017, FDA issued a warning letter to BioTE Medical, LLC following a facility inspection which found some of its products, including BioTE Omega 3, promoted for arthritis and other issues, adulterated in violation of quality control and other fish oil safety aspects of the cGMP.11. 
  • On September 15, 2016, FDA issued a warning letter to Positive Power Nutrition following a facility inspection which found the company’s Omega-3 Marine Lipid Oil and Super Silica and other products to be adulterated for several violations, including failure to implement quality control procedures for fish oil safety aspects of the cGMP.  Super Silica was promoted for arthritis.12. 
  • On July 22, 2016, FDA issued a warning letter to Viva Nutraceuticals (J&E International Corporation) following a review of the company’s website and promotional literature, which found statements about Golden Omega-3 Max and five other products to be drug claims in violation of fish oil safety and advertising aspects of the cGMP.13. 
  • On May 13, 2016, FDA issued a warning letter to Rocky Fork Formulas, Inc. following a facility inspection which found the company’s nine products, including EPA 1000 to be adulterated for several serious manufacturing infractions of the cGMP.   EPA 1000 was not intended for arthritis, but at least one of the nine supplements, Arthritis Complex HS was promoted for arthritis. 14. 
  • On October 1, 2015. FDA issued a warning letter to MPH Nutrition, LLC following a review of the company’s website which found statements made about an omega-3 supplement Re:Mind Recover, a supplement promoted for recovery from concussions, to be drug claims, including several serious violations of the cGMP.15. 
  • On May 4, 2015, FDA issued a warning letter to Dr Dennis Black, LLC, following a facility inspection which found the company’s 14 products, including Omega Oil 3,6,9 adulterated for serious manufacturing delinquencies regarding preparation, packing, ingredient identity, purity, strength, composition and labeling as required by federal regulations affecting fish oil safety.  In addition, statements made about the products on company websites were found to be drug claims.  Omega Oil 3,5,9 was promoted for inflammatory and autoimmune diseases, including rheumatoid arthritis.16. 
  • On August 29, 2013, FDA issued a warning letter to Y.S. Health Corp following a facility inspection which found five of the company’s products, including HiBee Heart’n Brain Ultimate Omega-3, adulterated for serious violations of quality control and manufacturing aspects of the cGMP.  In addition, statements about HiBee Heart’n Brain Ultimate Omega-3 and Arth 2000+ For Joint Flexibility and Pain Relief on the company website were found to be drug claims.  Fish oil safety was compromised for Ultimate Omega 3, which, along with Arth 2000+ were both promoted for arthritis.17.           
  • On March 19, 2013, FDA issued a warning letter to Sunset Natural Products Inc following a facility inspection which found more than 20 of its products, including Omega 3, to be adulterated with serious violations of federal regulations, including failure to test any dietary ingredients.  The fish oil safety of Omega 3 and other company products was compromised.  In addition, statements made about the supplements on the company’s website were found to be drug claims.  Omega 3 and other products were promoted for arthritis.18. 
  • On February 20, 2013, FDA issued a warning letter to Capco Custom Packaging Inc following a facility inspection which found the company’s liquid Omega-3 supplements, including Baby DHA and Pro DHA Infant to be adulterated for serious violations of the cGMP, including failures in quality processes for tests and examinations, and failure to modify protocols to ensure accordance for microbial contamination testing procedures.  Fish oil safety was compromised for these products, however they were not promoted for arthritis.19.

Fish oil safety: California lawsuit for illegal PCBs

A still unsettled 2010 lawsuit filed by environmentalists in California Superior Court in San Francisco claims popular brands of fish oil dietary supplements contain unsafe and illegal levels of the carcinogenic chemicals known as polychlorinated biphenyls, or PCBs (banned by Congress in 1979). 20

The plaintiff, Mateel Environmental Justice Foundation, targeted world-leading Omega Protein, a Houston-based corporation, and the companies they produce and label fish oil for, including CVS, GNC, Rite Aid, Solgar, Twinlab, Now Health and Pharmavite. The suit charged the defendants for marketing fish oil dietary supplements containing PCB levels that exceed California’s Proposition 65’s limit for human consumption of the contaminants, and illegally failing to disclose this to consumers on product labels.

The Mateel group alleged it only tested 10 omega-3 supplements manufactured by Omega Protein and found PCBs in all of them, ranging from 12 nanograms a day to more than 852 nanograms a day, based on the daily recommended label dosage.

California is the only state that requires labeling to warn consumers a product may contain trace amounts of PCBs, which have been tied to cancer and birth defects. 

Consumer Reports investigation: "Fish oil pills vs. claims"

Consumer Reports conducted its own study of fish oil brands (but not all brands) commonly found on the shelves of retail outlets in America, published in its January 2012 issue.20A

Entitled Fish Oil Pills versus Claimstheir testing revealed discrepancies in quality of 33% of those tested.

According to the article, “Americans are buying more fish-oil supplements than ever, but in industry-standard tests of 15 top-selling brands conducted by an outside lab for Consumer Reports, five fell a bit short.”  

None of the fish oil supplements contained contaminants, such as lead, mercury, or PCBs that exceeded levels set by USP or the European Union.  However, four of the fish oil supplements contained total PCBs in levels that would require warning labels under California’s Proposition 65, a consumer right-to-know law.20B

Study: 100% of children's omega-3 supplements contain PCBs

A 2013 journal study of fish oil safety, Children’s daily exposure to PCBs from dietary supplements containing fish oils, detected PCBs in all 13 over-the-counter children’s dietary supplements containing fish oil they assessed.21

The study was published in the journal Food Additives and Contaminants.  Its introduction comments that in children, omega-3 polyunsaturated fatty acids (PUFAs) may elicit a suite of health benefits, including enhancement of cognitive development, and these dietary supplements had increased in popularity.  Because the largest source of omega-3 PUFA;s is fish oil, which may contain significant levels of contaminants such as PCBS, the study objectives were to evaluate congener-specific PCB concentrations in children’s omega-3 fatty acids products from daily exposure.21  

Every supplement analyzed contained PCBs.  The researchers found when following serving size suggestions, mean daily exposure values ranged from 2.5 to 50.3 nanograms PCBs per day, significantly lower than those previously reported for adult supplements which generally had variability in the amount of fish oil (and PUFA content). In a serving size.21

In its conclusion, study authors said factors such as fish oil purification methods (e.g., molecular distillation) and the trophic level of the fish species used to make the fish oil cannot be used as indicators of PCB levels within children’s supplements, which may decrease or increase daily PCB exposure compared with the ingestion of fresh fish.  However, eating fish high in omega-3 PUFAs and low in PCBs may reduce PCB exposure compared with daily supplementation with fish oils for some products studied. 21

In a related but separate article, PCBs in Children’s Fish Oil Supplements, by Michael Greger, M.D. FACLM, published October 20, 2014 in, Dr. Greger commented on the above study: “….they found no significant difference in PCB levels between the supplements labeled as molecularly distilled or how high up the food chain the fish were.”   He added, “it’s bad enough when supplement manufacturers exploit adults when they’re sick and vulnerable with pills that are often useless or worse; but taking advantage of our parental drive to do what’s best for our children with contaminated products that may make them sick, makes me sick.”  22

(Editor’s note:  Which, when it comes down to fish oil safety, leaves supplement consumers for arthritis symptoms backed into the proverbial ‘buyer beware’ corner).

Article:  "Are your omega-3 supplements bogus?"

An article Are your omega-3 supplements bogus? in Prevention Magazine January 27, 2014 by Markham Heid commented on a report from LabDoor, a private company that tests consumer health products, that showed many fish oil supplements skimp when it comes to their omega-3 content—meaning you’re not getting what you pay for.23

Five of the 30 fish oil products tested fell 10% or more short of their advertised quantity of docosahexaenoic acid (DHA)—a type of omega-3 fatty acid that several studies have linked to improved heart and brain health, among other benefits.  Whether too high or too low, the average supplement label was off by 24% when it came to both DHA and eicosapentaenoic acid (EPA) content, according to the report.

The article commented that another private laboratory,, has conducted multiple tests of omega-3 supplements since 2001, with similar results.  Eleven of 35 supplements they examined in 2012 did not contain their labeled quantities of omega-3.  They also found that two products exceeded international limits for PCB safety.23

Why one leading manufacturer is trusted for fish oil purity

Finding superior quality in dietary supplements is always a challenge, regardless of the type of supplement you want.  Years ago, when searching for the best nutritional products on the market, I came up with a list of 30 probing questions. The answers led me to the #1 natural nutrition company in the U.S., established in 1956. Their obsession with science separates them from other manufacturers. Their 

business motto is The Golden Rule. Their integrity is well known in the industry, as is the purity, safety and effectiveness in the human body of their supplements.

Unlike their competitors, they prove the efficacy of each of their nutritional products through clinical tests.  Why is that a big deal?  Proof of efficacy IS NOT a requirement of the cGMP.  No other company that I know of routinely performs this additional step.  Their goal is to make each of their products the best that money can buy. 

They’ve invested more than $250 million in clinical testing, research and development and have over 135 trials on their own products, 100 of which are published in peer-reviewed scientific journals—more than any other nutritional company!   Their studies are openly published online and in product guides. 

Why one manufacturer claims their fish oil is the world's finest

When a manufacturer is trying to produce the best supplement for fish oil safety, testing methods are of utmost importance.  For example, the 'beyond organic' company we feature uses pharmaceutical grade state-of-the-art, proprietary, triple molecular distillation process that concentrates natural beneficial omega-3 fatty acids in three steps:

  • Step 1: Temperature and duration-controlled processing protects integrity of the finest quality fish oils.
  • Step 2: minimizes thermal heat degradation.
  • Step 3: low temperature multistep distillation process helps remove saturated fats, yielding pure, highly concentrated essential omega-3. Impurities and contaminants such as lead, mercury, arsenic, cadmium, dioxins and PCBs (often found in fish and fish oils) are removed.

The process produces the finest, better-for-your-health omega-3 supplement. 

It suppresses formation of dangerous trans fats. It’s free of saturated fat and cholesterol. It contains a full spectrum of seven omega 3 fatty acids, including EPA (eicosapentaenoic acid), DHA docosahexaenoic acid), ALA (Alpha Linolenic Acid), and five other naturally-found fatty acids including docosapentaenoic, stearidonic, eicosatetraenoic, heneicosapentaenoic, and alpha-linolenic acids.

For these reasons, the featured company’s omega-3 supplement is touted as the finest fish oil in the world. 

Our recommended omega-3 supplement is founded in personal experience

The omega-3 supplement taken by my husband and I has been formulated for maximum fish oil safety and minimum fishy aftertaste/odor, and contains higher levels of EPA and DHA than leading brands. It contains over 1200 mg of natural fish oil, including 363 mg EPA and 240 mg DHA per serving size of 2 softgels. Four softgels doubles the mg's shown above. Its label reads: "Take 2 softgels one or two times daily with meals." 

Concerned about fish oil safety? From more than twenty years personal experience we sincerely believe it is the very best fish oil supplement (scroll linked page for supportive details) available in the world. It contains 180 softgels, a three-month supply at two a day, or 45 days at four a day. A smaller size of 60 softgels is also available.

In addition to rheumatoid arthritis benefits, many studies promote fish oil for heart health
