What are Omega-3 Fatty Acids?

Omega-3 fatty acids are long-chain molecules considered healthy fats that balance out the bad fats in your diet.

Omega-3s are some of the most important essential nutrients we can consume for healthy metabolic performance.

The three most important essential fatty acids for health are:

1. Alpha Linolenic Acid (ALA), which is the main omega-3 found in plant foods.

2. Docosahexaenoic Acid (DHA)

3. Eicosapentaenoic Acid (EPA)- Both DHA and EPA are more closely associated with marine sources such as fish and algae.

Here's something you should know: the body prefers your fatty acids to be in EPA or DHA format. The body can convert ALA into EPA and DHA, but the average conversion is low at about 5-10% to EPA and below 5% to DHA. (29)

DHA and EPA are therefore considered to be the most effective long chain fatty acids. These fatty acids play a crucial role in promoting overall health, and will be the focus of this article.

Due to their far-reaching support for overall health and relative scarcity in typical diets, Omega-3s are among the most popular nutritional supplements, especially as fish oil.

Omega-3 Health Benefits

Omega-3s serve as phospholipid building blocks for the formation and maintenance of cell membranes.(1)

Cell membranes perform a dynamic range of bioactivities that orchestrate beneficial functions throughout your body.

DHA and EPA are drawn into cell membranes. They alter membranes’ structure to make them more supple, permeable and fluid.(2)

DHA and EPA support enhances performance of cell membrane bioactivities, which include:

• Barrier functions: Membranes’ selective permeability allows helpful substances in while keeping harmful substances out;

• Cell-to-cell communication: Membranes send and receive signals from other cells (using neurotransmitters and hormones);

• Immune modulation: DHA+EPA in cell membranes form and manage signaling compounds that balance immune system responses;

Essential fatty acid cell membrane support optimizes human performance at its most fundamental level. They promote healthy biological function in cells, tissues and organs throughout the body, across all life stages.

Omega-3 vs Omega-6 Fatty Acids

Omega-3 supplements may be taken in order to positively alter the composition of cell membranes throughout the body. Like olive oil at room temperature, they help cell membranes to stay fluid. This fluidity is crucial for maintaining optimal cell function and communication.

However, the balance of fatty acids in our diet can significantly influence the structure and function of these membranes.(3) While Omega-3s help maintain fluidity, an excess of Omega-6 fatty acids can disrupt this balance.

Omega-6 fatty acids are polyunsaturated fats, just like Omega-3s, and they are essential for health. However, when consumed in excessive amounts - especially in relation to Omega-3s - they can promote inflammation and negatively impact cell function.

Enzymes liberate fatty acids from cell membranes in order to produce hormone-like substances called eicosanoids.

Eicosanoids in turn perform several life-promoting bioactivities, including cell growth, blood clotting, muscle function and balanced immune responses.

• Omega-3s form eicosanoids associated with balanced and healthy responses(4)

• Omega-6s when not balanced with sufficient Omega-3 intake, can form eicosanoids that promote aggressive (unhealthy) inflammatory responses.(5)

When it comes to Omega-3 and Omega-6 fatty acids, it's the ratio that is key for overall health.

Optimal Omega-6 to Omega-3 Ratio

Experts suggest that an optimal ratio of omega-6 to omega-3 fatty acids is between 1:1 to 4:1, based on an ancestral balance. However, the average diet is now estimated to include up to a 20:1 ratio of omega-6 to omega-3.(6, 34)

Some reviews have suggested that this unbalanced ratio may contribute to serious long-range health implications, including an increased risk of obesity, cardiovascular concerns, bone and joint issues, mood problems, brain health concerns and more.(7)

In order to restore a healthy ratio, reduce intake of omega-6 rich foods and increase intake of omega-3 foods. A plant based diet such as a vegetarian diet or vegan diet may also support a more favorable omega-6 to omega-3 fatty acid ratio, which can help reduce inflammation.

Omega 6 vs Omega 3 Food Sources

Omega-6 foods include:

• Grain fed beef

• Some nuts and seeds

• Vegetable oils (sunflower oil, soybean, corn oil)

• Fried foods

• Bread and baked goods

• Processed foods

Best Omega-3 foods include:

• Fatty fish and fish oil

• Flaxseed and flaxseed oil

• Grass fed beef and dairy foods

• Chia seeds, hemp seeds, flax seeds

• Walnuts

Whole foods and other plant-based foods like chia can help raise ALA intake when EPA/DHA are not being used, and some vegans use 2–3 tablespoons of ground flaxseed daily for that purpose.

By hitting the optimal ratio you can support health in many ways, including:

Heart Health and Cardiovascular System

Omega-3s are most widely researched and acclaimed for their potential to support heart health. Researcher and review evidence has suggested they may help with:

• Heart rhythm stability(9)

• Blood vessel flexibility(10)

• Reducing blood viscosity(11)

• Triglyceride balance(12)

• Blood pressure regulation(13)

Strong clinical research on DHA+EPA has produced two FDA-qualified heart health claims.

Since 2004, the FDA has, under certain circumstances, exercised enforcement discretion for the following claim:

"Supportive but not conclusive research shows that consumption of EPA and DHA omega-3 fatty acids may reduce the risk of coronary heart disease."

In addition, the FDA has agreed to allow another EPA and DHA heart health claim, which reads:

"Consuming EPA and DHA combined may reduce blood pressure and reduce the risk of hypertension, a risk factor for coronary heart disease. However, FDA has concluded that the evidence is inconsistent and inconclusive." (31)

These findings should not be framed as a guaranteed prevention of heart attack. Omega-3s may also have positive effects on cholesterol balance by lowering LDL and potentially supporting HDL.

Don't let the conservative wording fool you: The FDA only allows a handful of health claims for nutrients found in supplements.

The above claims for both EPA and DHA are a testament to the large body of strong evidence supporting their benefits for heart health.

Recommended Dose: Did you know? The American Heart Association has advocated for increasing Omega-3 intake via two 3.5 oz. fish servings weekly (preferably oily fish) to support cardiovascular health. (32) A serving is 3oz cooked.
They increase this amount to 1g of EPA and DHA a day for people with existing coronary heart disease. (33)

Brain Health

Omega 3s supply nutritional support for nervous system health, especially the brain and eyes. DHA in particular supports brain health across all life stages, including pregnancy.

In early life (in the womb and with DHA-rich mother’s milk), they fuel rapid development of the brain, eyes, and nervous system. In adulthood, they help to maintain healthy neural structure and function.

Researchers have suggested DHA and EPA intake may help:

• Neurogenesis, the formation of fresh new brain cells(14)

• Plasticity, the dynamic connection of brain cells(15)

• Maintaining sharp cognition against age-related decline(16)

• Supporting healthy and balanced mood(17)

• Maintaining the overall size of the brain(18)

DHA+EPA far-reaching support for brain health, brain function, and cognitive function make them must-have nutrients in any nootropic program.

Omega 3 and Mental Health

Researchers have also investigated omega-3 fatty acids for potential benefits to mental health. There are meta-studies that suggest Omega 3 formulations rich in EPA may help to reduce depression symptoms. Research into its impact on anxiety, however, showed mixed experiences, suggesting more high-quality research is needed. (35)

Eye Health

As with the brain, DHA is highly concentrated in the eyes, where it is suggested to help vision health, performance and comfort:

DHA supports long-range eye health. Researchers have suggested that those with higher DHA intake through life appear to have less risk for age-related macular health concerns.(19)

DHA helps dry eyes. Dry Eye is when a lack of eye lubrication produces visual fatigue, blurriness, irritation and discomfort. Researchers suggest DHA may be an effective therapy for dry eyes.(20)

Research also suggests DHA may help with Computer Vision Syndrome by decreasing the rate of tear evaporation while improving dry eye symptoms associated with computer use.(21)

Muscle, Bone and Joint Health

Essential fatty acids’ overall health benefits include support for strength and flexibility. Some research suggests they may help the musculoskeletal system by:

• Promoting muscle protein synthesis (MPS)(22)

• Enhancing neuromuscular performance and fatigue resistance(23)

• Fighting muscle damage and soothing muscle soreness when taken post-workout(24)

• Maintaining joint comfort(25)

• Supporting bone mineral density(26)

These potential benefits are just a few of the reasons why many athletes and bodybuilders include Omega-3s as part of their sport nutrition regimen. Omega-3s also contribute to optimal health by supporting brain, heart, immune, and skin health.

Other Plant-Based Sources of Omega 3: Chia Seeds and More

Plant based foods or sources of omega-3 include foods such as chia seeds, flaxseed oil, soybean oil, and corn oil. These foods provide alpha-linolenic acid (ALA), a short-chain omega-3 fatty acid. However, ALA must first be converted by the body into EPA and DHA, the active forms used for brain, heart, and hormonal health, and this conversion process is typically inefficient in humans.

Unlike ALA-rich plant sources, which still relies on conversion pathways, algae-based omega-3 supplements provide EPA and DHA directly in a more bioavailable form.

For many people, the easiest way to increase DHA+EPA intake is to start taking a supplement.

However, most supplements on the market are made from fish oil, which have some drawbacks that, for many people, don’t make them the ideal choice.

Next, let’s look at some of these drawbacks, as well as revealing a vegan-friendly alternative source of essential fatty acids that is found in our #1 product this year.

Why Fish Oil Supplements are Old News

In order to get benefits, you must consistently consume DHA and EPA. Fish and fish oil are among the most common sources, but cleaner vegan dietary supplements avoid some of the concerns linked to them, including:(27)

• Persistent Organic Pollutants (POP)

• Mercury and heavy metals

• Polychlorinated biphenyls (PCBs)

• Organochlorine pesticides (OCs, including DDT)

• Dioxins

• Polybrominated Diphenyl Ethers (PBDEs)

These contaminants are among the health risks many buyers want to avoid when comparing fish based supplements with algae oil.

These toxins bioaccumulate in marine ecosystems. This means that as you move up the food chain, from smaller to larger fish, contaminants increase and concentrate.

Only after extensive processing - including cooking, de-sludging, washing, filtering, deodorizing and more - can fish be made into supplements.

Potential Fish Oil Side Effects

If you’ve ever taken fish oil, you may have experienced unpleasant side effects.

Most commonly, the dreaded fish burps. Sometimes softgels can taste bad (fishy) while you are taking them.

More often, fish oil softgels taste bad afterwards – taking the form of foul fishy-tasting burps that can persist for some time after taking the softgel.

Some of the better manufacturers take steps to reduce this issue, such as enteric coating and adding lemon oil or lemon flavor to their softgels.

But these add more processing steps, and do not necessarily eliminate the unpleasant fish oil side effects.

Negative Environmental Impact

Overfishing is bad for the environment, and fish oil supplements contribute to this problem.

Many fish oil supplements are derived from small fish like anchovies, herring, and menhaden, which feed on algae. These fish are often used because, being lower on the food chain, they have lower levels of bioaccumulated toxins.

While this makes them a safer choice for supplements, overfishing of these small fish disrupts the marine ecosystem. Depriving larger fish of a vital food source which can lead to imbalances, such as uncontrolled algae growth.

Krill oil, a popular alternative for its DHA and EPA content, faces similar environmental concerns due to the negative impact of krill harvesting on the food chain.

Furthermore, fish oil production typically requires extensive processing to ensure acceptable purity levels due to potential contamination. Despite these efforts, fish oil supplements remain problematic for the environment and are always going to be unsuitable for a vegan diet.

Fish Oil Supplements Don't Work for All Lifestyles.

Fish oil starts out questionable, then requires extensive processing to achieve acceptable purity.

Even then, fish oil still presents problems for our environment, and will never be suitable for vegan diets.

A vegan supplement, on the other hand, offers a plant-based source of omega-3 that fits a plant based diet, supporting brain and heart health while adhering to sustainable practices and quality testing procedures.

Today's top formula cuts out the middle man - fish - and instead supplies DHA+EPA directly from a direct source in all marine ecosystems: Algae.

Algae are very low in the food chain, so they do not have the same bioaccumulation that increases toxins moving up the food chain.

And because algae are a large biomass that can be sustainably cultivated, they have negligible impact on the environment.

Let's learn about the cleanest algal oil on the market to look for in today's leading supplements, before we decide on the best algae supplements.

Best Vegan Omega 3 Supplement: life's™Omega Algal Oil

life’s™OMEGA is sourced from the origin of Omega-3s in all marine ecosystems: Algae.

life’s™OMEGA is the first plant-based EPA and DHA combined product that provides both essential omega-3 forms as a direct source, rather than relying on plant conversion alone, making it a clean, eco-friendly and effective alternative to fish oil.

What Makes a Great Vegan Omega-3 Supplement?

Not all vegan omega-3 supplements are created equal. When comparing products, there are a few key factors worth considering.

• First, look for a supplement that provides both EPA and DHA directly from algae oil. While plant foods like flaxseed and chia contain ALA, the body converts only small amounts into EPA and DHA.

• Next, consider potency and form. High-quality algae omega-3 supplements supply meaningful amounts of EPA and DHA in their natural triglyceride form, which is generally better absorbed than synthetic ethyl ester forms.

• Purity also matters. Look for products that are third-party tested and produced under controlled conditions to help ensure quality and consistency. All Performance Lab products are third-party tested.

• Finally, consider sustainability and capsule quality. Algae oil offers a renewable alternative to fish oil, while vegan-friendly softgels can help avoid unnecessary animal-derived ingredients.

Performance Lab® Omega-3 was designed around these principles, combining life’s™OMEGA algal oil with carrageenan-free NutriGels® for a clean, vegan source of EPA and DHA.
