Over the past several years, Krill Oil has become the preferred source for Omega-3 supplementation. Why? Krill Oil is high in essential fatty acids (EFA), is more bioavailable than fish oil, contains a powerful antioxidant knows as Astaxanthin and has a longer shelf life than fish oil. So if you’re looking for a superior source of Omega-3, Krill oil is your answer.

What Is Krill Oil?

Krill oil is a dietary supplement derived from krill—tiny, shrimp-like marine crustaceans that inhabit the deep, cold waters of the Antarctic Ocean. These creatures feed primarily on phytoplankton, making them a vital part of the ocean’s food chain and a rich source of omega-3 essential fatty acids.

Krill may be small, but they represent a massive presence in the marine ecosystem. In fact, krill account for the largest biomass of any animal species in the world, with an estimated population mass of over 389 million tons
Atkinson et al., 2009, Deep-Sea Research Part II.

In simpler terms—krill aren’t going anywhere. Their abundance and rapid reproduction make them one of the most sustainable sources of omega-3s available.

Krill Oil Is High in Essential Fatty Acids (EFAs)

What makes krill oil particularly valuable is its high concentration of essential fatty acids—especially:

Eicosapentaenoic acid (EPA)
Docosahexaenoic acid (DHA)

These long-chain omega-3 fatty acids are critical for:

Cardiovascular health
Cognitive function
Reducing inflammation
Supporting joint and muscle recovery
Calder, 2015, Nutrients

Unlike fish oil, the omega-3s in krill oil are bound to phospholipids, not triglycerides. This unique structure allows for superior absorption and bioavailability, making krill oil more efficient at delivering its benefits with lower doses compared to traditional fish oil
Ulven & Holven, 2015, Frontiers in Nutrition.

Additionally, krill oil contains astaxanthin, a powerful marine antioxidant known for its role in:

Fighting oxidative stress
Supporting immune function
Reducing signs of aging
Fassett & Coombes, 2011, Marine Drugs

Why Essential Fatty Acids Matter — And Why You Should Take Krill Oil

For those who may not be familiar, essential fatty acids (EFAs) are fats that your body requires to function properly—but cannot produce on its own. These include:

Omega-3 fatty acids (anti-inflammatory)
Omega-6 fatty acids (pro-inflammatory)

While the body can synthesize certain fats, omega-3 and omega-6 must be obtained through food or supplementation
Simopoulos, 2002, Biomedicine & Pharmacotherapy.

The Omega Imbalance in the Modern Diet

Here’s the issue: the typical American diet is heavily skewed toward omega-6s, primarily from processed seed oils, fried foods, and packaged snacks. Omega-6 is involved in initiating inflammation, which is necessary in small amounts—but problematic when unbalanced.

On the flip side, omega-3s help reduce inflammation and support critical processes such as:

Brain function
Joint mobility
Mood regulation
Cellular repair
Skin health
Calder, 2015, Nutrients

Unfortunately, most people consume far too much omega-6 and not enough omega-3, leading to potential issues like:

Chronic fatigue
Joint pain or stiffness
Mood swings or irritability
Brain fog and poor focus
Dry or inflamed skin

Why Krill Oil Is the Solution

This is where krill oil shines. Rich in EPA and DHA, krill oil helps restore the omega-3 to omega-6 balance, lowering systemic inflammation caused by a poor diet. Unlike omega-6, which already dominates your plate, omega-3 is often missing—and krill oil offers it in its most bioavailable form.

Its unique phospholipid structure allows for faster absorption and better cellular integration than fish oil, and its astaxanthin content provides powerful antioxidant protection.

So, if you're wondering whether you should be taking omega-3s—the answer is clear: yes, you should. And krill oil is one of the most efficient, sustainable, and effective ways to do it.

Krill Oil Helps Slow Down the Aging Process

One of the most compelling benefits of krill oil lies in its potential to support skin health and slow the visible signs of aging. Thanks to its unique combination of omega-3 fatty acids (EPA and DHA) and the powerful antioxidant astaxanthin, krill oil helps reduce oxidative stress and support skin structure and hydration at the cellular level.

Astaxanthin has been shown to neutralize free radicals, which—when present in high concentrations due to UV exposure and environmental damage—can lead to:

The breakdown of collagen and elastin
Loss of skin elasticity
Wrinkles and age spots
Fassett & Coombes, 2011, Marine Drugs

Meanwhile, the omega-3 content in krill oil helps normalize skin lipids, keeping skin barrier function strong and promoting deep hydration, which reduces the appearance of fine lines and enhances skin texture.

What the Research Says

Clinical evidence suggests that supplementing with krill oil can:

Improve skin elasticity
Reduce wrinkles and fine lines
Even out skin texture and tone
Chalyk et al., 2017, Lipids in Health and Disease

Recommended dosage: At least 500 mg of krill oil daily to support skin and cellular health.

RECOMMENDED PRODUCT: Krill Oil + Astaxanthin (60 Servings)

Krill Oil Helps Elevate Mood

Eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA)—the two primary omega-3s in krill oil—have shown impressive potential in supporting mental health, particularly when it comes to elevating mood and reducing symptoms of depression.

DHA plays a role in increasing serotonin and dopamine, neurotransmitters often referred to as the brain’s “feel good” chemicals
EPA has been shown to reduce inflammation in the brain, which may play a role in neuroinflammation-related depression
Su et al., 2015, Journal of Clinical Psychiatry

Clinical studies have compared the mood-enhancing effects of omega-3s to some antidepressants, showing similar biochemical impacts on neurotransmitter regulation—without the side effects.

Krill Oil Helps Treat PMS Symptoms

From bloating and fatigue to mood swings and joint pain, premenstrual syndrome (PMS) affects millions of women each month. The common thread among many of these symptoms? Inflammation.

Krill oil, with its potent anti-inflammatory properties, has been shown to significantly reduce:

Menstrual cramps and joint/muscle pain
Bloating, digestive issues, and fatigue
Headaches and backaches

Emotionally, the mood-lifting effects of krill oil can also help manage the mental and hormonal fluctuations of PMS. This includes:

Reduced anxiety and irritability
Improved focus and cognitive clarity
Stabilized mood swings

These outcomes are largely attributed to increased dopamine and serotonin secretion, as well as reduced neuroinflammation during the luteal phase of the menstrual cycle.

Whether you're looking for a more natural solution to support emotional wellness, skin clarity, or monthly symptom relief—krill oil offers a powerful, research-supported solution.

Krill Oil Benefits: Better Brain Health

One of the most compelling long-term benefits of krill oil is its role in protecting cognitive function. The Framingham Heart Study, one of the most well-known longitudinal health studies in the U.S., followed 5,209 individuals from Framingham, Massachusetts over a 57-year period.

Among its many findings, researchers discovered that individuals who consumed just 180 mg of DHA per day—about 2.5 servings of fish per week—experienced a 50% reduced risk of developing dementia
Tan et al., 2012, Alzheimer’s & Dementia.

For most people, dementia may seem like a distant concern—but anyone who has witnessed a loved one struggle with memory loss knows just how devastating it can be. The ability to recognize loved ones, navigate everyday life, and retain independence is not guaranteed as we age—but research suggests that omega-3 supplementation can help protect these cognitive functions.

Taking krill oil consistently now may serve as a powerful tool in your long-term brain health strategy—while you can still remember to do it.

Krill Oil Supports a Healthy Heart

Heart disease remains the leading cause of death in the United States, and with obesity rates on the rise, cardiovascular risk continues to grow
CDC, 2023.

What if you could significantly reduce your risk with one daily habit?

That’s exactly what a landmark study published in the New England Journal of Medicine found. Starting in the mid-1980s, researchers followed 20,551 male physicians over 17 years. The results?

Those with the highest blood levels of DHA and EPA had a 90% lower risk of sudden cardiac death
Albert et al., 2002, NEJM

EPA and DHA—both found in abundance in krill oil—play a key role in:

Reducing triglycerides
Lowering blood pressure
Raising HDL ("good") cholesterol
Decreasing inflammation in arterial walls

If you're looking to extend both your lifespan and healthspan, krill oil is one of the most well-researched and effective natural options available.

Krill Oil Supports Healthy Joints

Inflammation is a necessary part of the body's repair system, but chronic inflammation—especially in joints and connective tissue—can lead to discomfort, reduced mobility, and long-term pain.

Krill oil contains potent anti-inflammatory compounds, including EPA, DHA, and astaxanthin, that help reduce swelling, stiffness, and discomfort in joints and surrounding tissues
Deutsch, 2007, Journal of the American College of Nutrition.

How It Works:

Astaxanthin helps reduce oxidative stress and inflammation at the cellular level
Krill oil lowers levels of C-reactive protein (CRP)—a key inflammatory marker produced by the liver
Regular use of krill oil has been shown to improve joint mobility, particularly in those with arthritis or post-exercise joint pain

If you’re experiencing soreness after workouts or dealing with early signs of arthritis, krill oil can help reduce pain, improve flexibility, and enhance recovery.

Should I Take Krill Oil? Takeaway

We could go on for hours about the benefits of krill oil—how it supports cell membrane integrity, hormone production, brain and nervous system function, and even thyroid and adrenal health.

But here’s the bottom line:

You are not getting enough omega-3s from food. Period.

Most diets today—yes, even the "clean" ones—are omega-3 deficient and omega-6 dominant. This imbalance creates systemic inflammation, disrupts metabolic processes, and slowly starts to shut down critical systems in your body.

You may not notice it today, but if you’re struggling with:

Brain fog or low energy
Joint stiffness or soreness
Mood swings or low motivation
Skin issues or poor recovery
Hormonal irregularity

There’s a good chance your omega-3 to omega-6 ratio is off.

And the only question that matters now is:
Are you going to do something about it?

Supplementing with a high-quality krill oil is one of the simplest, most effective ways to start taking back control of your health—at the cellular level.
