Discover the importance of omega-3 fatty acids for your health and cognitive function.
Omega-3 fats are not just another dietary component; they are essential building blocks that play a crucial role in maintaining the health and functionality of our cell membranes and mitochondria.
Understanding the Role of Omega-3 Fats
Our cell membranes and mitochondria, essential structures within our cells, are primarily composed of phospholipids and other constituents. The foods we consume provide the raw materials necessary for assembling these membranes. This is where the type of fats we eat becomes critical.
While omega-6 linoleic acid (LA) is considered essential, it’s abundantly present in most diets, often due to processed food consumption. On the other hand, omega-3 alpha-linolenic acid (ALA) is truly essential since our bodies cannot produce it. However, our ability to synthesize other omega-3s like EPA and DHA is hindered when omega-6 intake is excessively high.
Maintaining Balance and Overcoming Challenges
A diet rich in processed foods skews the omega-3 to omega-6 ratio, inhibiting the synthesis of EPA and DHA. By returning our LA intake to historical norms and ensuring a baseline level of ALA, we can optimize the production of these critical omega-3 fats without the need for supplements.
Recognizing Imbalance and Taking Action
Signs of an omega-3 to omega-6 ratio imbalance include skin issues, fatigue, menstrual cramps and poor attention span. The ideal ratio is around 1:1, but the typical Western diet falls far from this mark. To rebalance, it’s essential to increase omega-3 intake while reducing omega-6 consumption, which entails cutting down on processed and fried foods.
Sources of Omega-3 Fatty Acids
Fatty fish like wild-caught salmon, mackerel, sardines, and anchovies are excellent sources of omega-3 fats. Alternatively, krill oil supplements offer superior absorption and antioxidant benefits due to their phospholipid structure and high astaxanthin content.
Common Fish and Their Mercury Levels
Tuna: Tuna, especially larger species like albacore or bigeye tuna, tends to have higher mercury levels. While canned light tuna generally contains less mercury compared to canned white or albacore tuna, it’s still advisable to consume tuna in moderation, especially for pregnant women and those with health conditions affected by mercury exposure.
Swordfish: Swordfish is known to have high mercury levels due to its large size and predatory nature. Consumption of swordfish should be limited, particularly for vulnerable populations.
Shark: Shark meat contains high levels of mercury, making it unsuitable for regular consumption, especially for pregnant women, nursing mothers, and young children.
King mackerel: King mackerel is another fish species known for its high mercury content. It’s advisable to limit consumption, especially for individuals susceptible to mercury toxicity.
Tilefish: Tilefish, particularly from the Gulf of Mexico, is known to have elevated mercury levels. Avoiding tilefish, especially for pregnant women and young children, is recommended.
Marlin: Marlin is a large predatory fish with high mercury levels. Consumption should be limited or avoided altogether.
Orange roughy: While not as commonly consumed as other fish, orange roughy can have high mercury levels due to its longevity and slow growth.
Mercury is a potent neurotoxin that can accumulate in the body over time, potentially leading to adverse health effects, especially for those with certain health conditions like ADHD, bipolar disorder, and rejection sensitive dysphoria. High levels of mercury exposure can impair cognitive function, affect mood stability, and exacerbate symptoms associated with these conditions.
To mitigate the risk of mercury exposure, individuals should opt for fish varieties with lower mercury levels, such as salmon, sardines, trout, and shrimp. Additionally, consuming a balanced diet rich in omega-3 fatty acids from sources like flaxseeds, chia seeds, walnuts, and omega-3 supplements derived from algae can help maintain optimal omega-3 to omega-6 ratios without the risk of mercury contamination. It’s crucial to prioritize food safety and make informed choices to support overall health and well-being.

Addressing Common Questions
- Do omega-3 fatty acids help with ADHD?
Studies have indicated that individuals with ADHD may have lower levels of omega-3s and supplementation could help alleviate symptoms such as poor attention span and impulsivity.
Fatty fish like salmon, mackerel and sardines are excellent sources of omega-3s, along with krill oil supplements. We here at AllNaturWell suggest only the best fish be consumed. You can see our recommendations here.

- Does omega-3 clear brain fog?
While omega-3 fatty acids may not directly clear brain fog, their role in supporting brain health and function could indirectly contribute to mental clarity and focus. By maintaining a balanced diet that includes omega-3-rich foods, individuals may optimize their cognitive function and potentially alleviate symptoms associated with ADHD.
- Are there are tests available to measure omega-3 levels in the body?
Yes, there are tests available to measure omega-3 levels in the body. One common test is the Omega-3 Index, which measures the levels of EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid) in red blood cell membranes. Another test is the Omega-3:Omega-6 Ratio, which compares the levels of omega-3 fatty acids to omega-6 fatty acids in the blood. These tests can provide valuable insights into whether omega-3 levels are optimal or imbalanced, helping individuals make informed decisions about their dietary intake and supplementation. Talk to your health care provider about this simple test.
When Considering Omega-3 Supplements
When considering omega-3 supplements, it’s essential to choose high-quality options that provide adequate levels of EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid), the two primary forms of omega-3 fatty acids with proven health benefits. Here are some of the best omega-3 supplements recommended by healthcare professionals:
Fish Oil: Fish oil supplements derived from cold-water fatty fish like salmon, mackerel, and sardines are among the most popular choices. They typically contain a combination of EPA and DHA, which support heart health, brain function and overall well-being. Look for fish oil supplements from reputable brands that undergo third-party testing to ensure purity, potency and absence of contaminants like mercury and PCBs. We suggest beginning your research with BePure.
Krill Oil: Krill oil is extracted from tiny crustaceans called krill and contains omega-3 fatty acids in the form of phospholipids, which may enhance absorption compared to fish oil. Krill oil also contains astaxanthin, a powerful antioxidant that provides additional health benefits. Krill oil supplements are suitable for individuals seeking a sustainable alternative to fish oil and may be better tolerated by those prone to fishy aftertaste or burping. We suggest beginning your research with Carlyle.
Algal Oil: Algal oil is derived from algae and is an excellent option for vegetarians, vegans, and individuals allergic to fish. It provides a direct source of DHA and EPA, as algae are the primary source of omega-3 fatty acids in the marine food chain. Algal oil supplements offer the same health benefits as fish oil without the risk of environmental contaminants or concerns about overfishing.

Cod Liver Oil: Cod liver oil is a traditional remedy rich in omega-3 fatty acids, vitamins A and D and other nutrients. It supports immune function, bone health and vision, in addition to providing essential omega-3s. However, individuals should be cautious about consuming cod liver oil in excessive amounts due to its high vitamin A content, which can be toxic at high doses. We highly suggest consulting your health care provider and beginning your research with Carlyle.
Flaxseed Oil: Flaxseed oil is a plant-based source of alpha-linolenic acid (ALA), a type of omega-3 fatty acid. While ALA is a precursor to EPA and DHA, its conversion efficiency in the body is limited. Flaxseed oil supplements are suitable for vegetarians and may provide some cardiovascular and anti-inflammatory benefits, although they may not be as effective as marine-based omega-3s for certain health conditions. We suggest beginning your research with Barlean’s.
When choosing an omega-3 supplement, consider factors such as the concentration of EPA and DHA, purity, sustainability and potential allergens. It’s advisable to consult with a healthcare professional or registered dietitian to determine the most appropriate omega-3 supplement based on individual health needs, dietary preferences and lifestyle factors. Additionally, incorporating omega-3-rich foods like fatty fish, nuts and seeds into your diet can complement omega-3 supplementation and promote overall health and well-being.
