Are Omega 3 Supplements Good For You

Omega-3 fatty acids, often simply referred to as omega-3s, are a type of polyunsaturated fatty acids which are indispensable for our body's optimal functioning. As your body cannot produce these essential nutrients, they must be incorporated through your diet or omega-3 supplements. There are three primary types of omega-3s: eicosapentaenoic acid (EPA), docosahexaenoic acid (DHA), and alpha-linolenic acid (ALA), collectively known as omega 3 fatty acids. But the question remains,

are omega 3 supplements good for you?

Let's delve into the world of omega-3s to understand their benefits of omega 3, sources, and potential side effects, with a particular emphasis on the premium omega-3 supplement - "Good Fats" by Lean Greens.

The Science Behind Omega-3 Fatty Acids

Omega-3 fatty acids are an integral part of every cell's support structure in your body, playing a pivotal role in brain health and eye health. They are found in high amounts in the cells of your eyes and brain, endorsing their importance in maintaining overall health and wellness.

The Role of Omega-3s in Your Body

Omega-3 fatty acids, commonly referred to as Omega-3s, are not just beneficial, but they play a pivotal role in a myriad of bodily functions. They are instrumental in the production of energy, acting as a vital fuel source for your body.

The benefits of fish oil include providing robust support for cardiovascular health, contributing to a strong and healthy heart. They also play a significant role in the optimal functioning of the endocrine system, which is responsible for regulating hormones.

Moreover, Omega-3s are absolutely essential for cognitive function, playing a key role in mental processes and memory. Lastly, they are crucial for the health of your eyes and brain, contributing to overall neurological health and vision.

What are Omega 3s?

There are three primary types of omega 3 fatty acids:

  1. Eicosapentaenoic acid (EPA): Predominantly found in fish.
  2. Docosahexaenoic acid (DHA): Also abundant in fish.
  3. Alpha-linolenic acid (ALA): Primarily present in plant foods.


The Benefits of Omega-3 Fatty Acids

The potential health benefits of omega 3 fatty acids are numerous, ranging from supporting heart health to reducing inflammation and managing certain mental disorders. Here are some significant ways in which the benefits of omega 3 fish oil might improve your health:

Heart Health and Omega-3s

Omega-3 fatty acids, specifically those known as EPA (Eicosapentaenoic Acid) and DHA (Docosahexaenoic Acid), have been scientifically associated with a multitude of benefits for heart health. Which answers the question of do omega 3 lower triglycerides?

Some of these benefits encompass the reduction of triglycerides, which are a type of fat found in your blood that can increase your risk of heart disease if levels are too high. Additionally, these fatty acids are known to increase the levels of HDL, often referred to as the 'good' cholesterol, in the body. This is beneficial as higher levels of HDL cholesterol can help reduce the risk of heart disease.

Moreover, omega-3 fatty acids contribute to the lowering of blood pressure, another key factor in maintaining heart health. However, it's crucial to highlight that while these heart benefits are typically associated with diets rich in omega-3, the research conducted on omega-3 supplements has not always produced consistent results. Some studies show benefits, while others do not, indicating that more research is needed in this area.

Importance of DHA for Eye Health


DHA (Docosahexaenoic Acid) is a type of omega-3 fatty acid that plays a crucial role in maintaining eye health. It is particularly vital for the integrity of the retina, which is a key component in our ability to see. Here’s why DHA is essential for ocular health:

  • Retinal Integrity: DHA is a major structural component of the retina, the part of the eye responsible for converting light into neural signals that the brain interprets as vision. Adequate levels of DHA help maintain the structure and function of the retina, ensuring optimal visual performance.
  • Preventing Macular Degeneration: Macular degeneration is a condition that can lead to vision loss. DHA's role in maintaining retinal health is crucial in preventing this condition, as it helps protect the cells in the macula (part of the retina) from damage.
  • Vision Problems: Insufficient levels of DHA can lead to various vision problems, including difficulties with visual acuity (sharpness of vision), night vision, and the development of conditions like dry eye syndrome. Ensuring adequate intake of DHA is important for avoiding these issues.

Sources of DHA

To maintain adequate levels of DHA for eye health, consider incorporating the following sources into your diet:

  • Fatty Fish: Such as salmon, mackerel, and sardines are rich in DHA.
  • Algae Supplements: A plant-based alternative for vegetarians and vegans, algae oil supplements provide DHA.
  • Fortified Foods: Some eggs and dairy products are fortified with omega-3s, including DHA.

DHA is an essential omega-3 fatty acid for maintaining eye health, especially for the integrity of the retina and in preventing macular degeneration. Ensuring sufficient intake of DHA through diet or supplements is crucial for preventing various vision problems and maintaining overall ocular health.

Understanding the Role of Omega-3s in Managing Depression and Anxiety

Omega-3 fatty acids, especially EPA (Eicosapentaenoic Acid), have been spotlighted for their potential benefits in managing mental health conditions such as depression and anxiety. Here's a closer look at how omega-3s can contribute to mental wellness:

Benefits of Omega-3s in Mental Health

  • Depression and Omega 3: Research suggests that individuals who incorporate omega-3s into their diet have a lower incidence of depression. Omega-3 supplements, particularly those high in EPA, can also help improve symptoms in people who haven't found relief from traditional antidepressant medications.
  • Anxiety Management: Besides depression, omega-3 fatty acids have also been linked to reductions in anxiety levels. This is particularly significant for individuals looking for natural methods to manage anxiety symptoms.
  • Enhanced Brain Function: Omega-3s play a crucial role in brain health, contributing to better cognitive function and emotional well-being. This can indirectly support mental health by improving overall brain function.


How Omega-3s Work for Mental Health

  • Anti-inflammatory Effects: Omega-3s have anti-inflammatory properties that might help counteract the inflammation associated with depression and other mood disorders.
  • Neurotransmitter Regulation: They may also influence the function of neurotransmitters within the brain, including serotonin and dopamine, which play key roles in mood regulation.
  • Brain Cell Support: Omega-3 fatty acids are essential components of brain cell membranes, supporting the repair and maintenance of brain cells, which is vital for optimal mental health.

Omega-3 Supplements: Are They Safe?

When it comes to the question, are omega 3 supplements good for you, the answer largely depends on individual factors such as existing health conditions, dietary habits, and specific lifestyle factors. While omega-3s are considered safe for most people, it's crucial to consult with a healthcare provider before starting any new supplement regimen. One of the questions we get asked regularly is "Can Omega 3 Cause Weight Gain"? Categorically no, so long as you pick the right type of Omega 3 supplements

Potential Side Effects of Omega-3 Supplements

While generally safe, omega-3 supplements can have side effects, such as indigestion, gas, and occasionally a fishy aftertaste, which are common fish oil side effects that some individuals may experience.

Interaction with Medications

Omega-3 drug interactions are an important consideration, especially if you're taking anticoagulant or antiplatelet medications, as omega-3 supplements could potentially heighten bleeding risks. Consulting your healthcare provider before commencing omega-3 supplements is crucial if you're on any medications.

Omega-3 Supplement Dosage

Omega 3 fats are essential fats that our bodies need but cannot produce on their own, thus they must be obtained through our diet. These fats are pivotal for maintaining heart health and have been linked to a lower risk of heart attacks and strokes. The UK Heart Health website provides comprehensive insights into the types of omega 3 fats, their sources, and their benefits for cardiovascular health.

Types of Omega 3 Fats

  • ALA (Alpha-linolenic acid): This is primarily found in vegetable oils, nuts, and seeds. Our bodies can't produce ALA, making it essential to include it in our diet.
  • EPA (Eicosapentaenoic acid) and DHA (Docosahexaenoic acid): These are found in oily fish and are crucial for heart health. Our bodies can convert a small amount of ALA into EPA and DHA, but it is beneficial to consume these directly through our diet.

Sources of Omega 3s

Oily Fish

The best sources of these essential nutrients are found in oily fish. To meet the recommended omega-3 intake, it is advised to consume two portions of fish per week, with at least one being an oily variety.

Recommended Oily Fish Options:


  • Salmon: Renowned for its high omega-3 content, salmon is also a great source of protein and vitamins B and D.
  • Mackerel: In addition to omega-3s, mackerel offers a significant amount of vitamin B12 and selenium.
  • Sardines: Small yet mighty, sardines are packed with omega-3s, vitamin D, calcium (from the bones), and protein.
  • Trout: A freshwater alternative, trout is rich in omega-3 fatty acids, B vitamins, and is an excellent source of protein.

Incorporating these fish into your diet not only supports heart and brain health but also contributes to a balanced and nutritious diet.

Understanding Omega-3 Fatty Acids in a Vegetarian Diet

Omega-3 fatty acids are crucial for maintaining heart health, supporting brain function, and reducing inflammation throughout the body. While fish and fish oil supplements are commonly recommended sources of omega-3s, vegetarians and individuals who don't consume fish can still meet their omega-3 fatty acid needs through plant-based sources. The primary type of omega-3 found in plant foods is alpha-linolenic acid (ALA), which the body can partially convert to eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), the forms more readily used by the body. Here are some excellent plant-based sources of ALA:

Plant-Based Sources of ALA


  • Flaxseed Oil: One of the richest plant sources of ALA, flaxseed oil can be used as a salad dressing or mixed into smoothies. It's important not to cook with flaxseed oil as high temperatures can destroy its nutrients.
  • Walnuts: Not only are walnuts a good source of ALA, but they also provide protein and fiber. They make a great snack or can be added to salads, oatmeal, and baked goods.
  • Green Leafy Vegetables: Vegetables such as spinach, kale, and Brussels sprouts contain smaller amounts of ALA but are still valuable sources, especially when consumed in large quantities. Incorporating a variety of green leafy vegetables into your diet can also provide other essential nutrients.

Additional Sources of Plant-Based Omega-3s

  • Chia Seeds: These tiny seeds are not only high in ALA but are also rich in fiber and protein. They can be soaked in water or plant-based milk to make chia pudding, sprinkled on top of yogurt, or blended into smoothies.
  • Hemp Seeds: Hemp seeds offer a good amount of ALA along with protein, making them a nutritious addition to your diet. They can be sprinkled on salads, added to smoothies, or mixed into oatmeal.
  • Edamame: Young soybeans, or edamame, contain ALA as well as protein, fiber, and various vitamins and minerals. They can be enjoyed as a snack or added to soups, salads, and stir-fries.

Tips for Maximizing Omega-3 Absorption from Plant Sources

  • Eat a variety of sources: To ensure you're getting enough ALA, include a variety of the foods mentioned above in your diet regularly.
  • Combine with healthy fats: Consuming these foods with other healthy fats can help increase the absorption of omega-3 fatty acids. For example, adding olive oil to your leafy greens or eating nuts and seeds with avocado.
  • Vegan Omega 3 Suppplements: For those who may struggle to consume enough ALA through diet alone, algae-based omega-3 supplements are a vegan-friendly option that provides EPA and DHA directly.

Incorporating these foods and tips into your diet can help ensure you receive the essential omega-3 fatty acids necessary for optimal health, even without consuming fish or animal products.

Fortified Foods

Some foods are fortified with omega 3s, but it's important to note that these usually contain ALA rather than EPA or DHA. While there's ongoing research, the consensus is that it's better to get omega 3s from food sources rather than supplements.

Determining the Right Omega 3 Dosage

When it comes to determining the right dosage of omega 3 per day, it's crucial to consult with a healthcare provider. The ideal dosage can vary based on individual health goals and needs. The UK Heart Health website suggests aiming for at least 500mg of EPA and DHA combined each day, equivalent to around a 140g portion of oily fish per week. However, for specific health conditions or goals, the dosage may need to be adjusted.

Good Fats by Lean Greens: A Premium Omega-3 Supplement

Lean Greens' 'Good Fats' stands out as the best omega-3 supplement in the UK, crafted to deliver the omega-3 supplements benefits your body requires. Its superior formulation ensures you get the most effective absorption and benefits.

How is it superior? Very simply it comes down to dosage of the EPA/DHA Omega 3 in the product, with 750mg in just a single softgel capsule. Unlike most others available from Amazon or your local store, which commonly contain less than 300mg per capsule.

This means with Good Fats Omega 3 you can take just a single capsule a day for a very effective maintenance dose. 2 capsules per day if your fish consumption is low. Or 3 capsules per day if your diet is completely devoid of any fish.

'Good Fats' may be a beneficial addition to your diet, particularly if you're not getting sufficient omega-3s from food. Nonetheless, it's wise to consult a healthcare professional before incorporating 'Good Fats' or any dietary supplements into your regimen.
