Adaptogens have been around for thousands of years, used as part of Traditional Chinese Medicine (TCM) and Ayurveda (ancient Indian medicine), although the actual term “adaptogens” is a more modern categorization coined in the 1940s by a Soviet scientist, Nikolay Lazarev.  The usage of herbs such ashwagandha and Panax ginseng were essential assets in the ancients’ medical toolboxes, helping combat exhaustion and restore equilibrium.

Today, these herbs and others and some mushrooms are known as adaptogens, which are growing in popularity and are sold without prescription as dietary supplements, in foods and spices, and teas and beverages.

Likewise, omega-3s are widely recognized as healthful dietary supplements. Omega-3s burst onto the scientific scene in the late 1970s  when omega-3 EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid)—also known as fish oil—energized the research community with this scientific publication hypothesizing that EPA could reduce risk for thrombosis and atherosclerosis. Nearly 50 years later, omega-3s are well-supported by modern scientific research for numerous health conditions.

Both omega-3s and adaptogens are thought to help elevate mood and relax stress levels and further are associated with resilience and overall well-being. So, it would be natural to wonder whether omega-3s are adaptogens. In today’s blog, we’ll explore the similarities and differences between the two and explain why omega-3s are not adaptogens—but worthy of consideration for your health.

What is an Adaptogen?

By definition, Science Direct posted an AI-generated explanation of adaptogens that notes these substances “improve the general function of the organism by modulating endocrine responses, enhancing the capacity for autoregulation, and supporting the immune system, thereby facilitating adaptation to various stressors.”

This article simplifies the basic concepts which define the workings of adaptogens to be as follows:

• Non-toxic at normal doses, causing minimal disturbance to the organism
• Support the entire body’s ability to cope with stress
• Help the body return to a stable state

This translates to potential benefits from the herbs and from mushrooms that are identified as adaptogens to help your body cope with stress, both emotional and physical. Additionally, some adaptogens can help reduce inflammation, support immunity and fight exhaustion, but this article advises the claims may be lacking in research, especially large human trials.

 

Adaptogens: From Niche to Mainstream  

According to Grand View Research, in 2024 the global adaptogens market was estimated at nearly $11 billion with a projected reach by 2030 of $16 billion, representing a CAGR (compound annual growth rate) of 7.2% from 2025 to 2030.

Having its moment, perhaps fueled by celebrity curiosity and endorsements, adaptogens are the current cool tool for addressing certain health issues. With mega-influencers such as Bella Hadid, Katy Perry, and even Oprah and Gwyneth leading the charge, it’s no wonder that us common folk are intrigued by adaptogens, which have moved from niche to mainstream.

 

Is Omega-3 Considered an Adaptogen? 

Despite omega-3s and adaptogens both being known as stress-relievers, inflammation-reducers, and mood-supporters, quite simply, omega-3s are not adaptogens.  Omega-3s are actually closer to vitamins than to adaptogens, as they’re considered essential to basic bodily functions: necessary for cell membrane growth and cell structure; to promote eye and brain development; and to support bodily systems including cardiovascular, endocrine and immune function.

And like most vitamins, your body does not produce enough omega-3s on its own, thereby making it necessary to obtain omega-3s from outside sources, such as conventional foods, functional and fortified foods, or dietary supplements. But omega-3s are also not one of the 13 essential vitamins.

Instead, omega-3s are essential nutrients, falling into the category of unsaturated fatty acids, the healthy kinds of fats that are good for you. And even though many adaptogens are sourced from plants, even the plant-based omega-3 ALA (alpha-linolenic acid) is not categorized as an adaptogen.

Why Are Omega-3s and Adaptogens Often Confused?

Both omega-3s and adaptogens are marketed to support overall wellness, lessen inflammation, reduce anxiety or stress, improve mood and mental focus, help relieve fatigue, enhance endurance and boost immune function.

While omega-3s have been mainstream since the early 2000s, their climb in the 90s was helped by health-oriented celebrities and other influencers, such as health guru Dr. Andrew Weil and Dr. Barry Sears, creator of the Zone Diet.

So, it seems that omega-3s and adaptogens share not only an overlapping health benefits story but also a celebrity influencer marketing story, which for both omega-3s and adaptogens helped their popularity rise. However, there are also key differences between the two.

Adaptogens vs. Omega-3s: Understanding the Key Differences

While both adaptogens and omega-3s can provide health benefits, there are differences between the two. Below are four of those differences.

1. The mechanisms of how they work are different. Let’s take stress as an example. This article advises that adaptogens can help the body adapt to stress by influencing the hypothalamic-pituitary-adrenal (HPA) axis, the body’s command center for regulating your body’s reaction to stress. The three organs that comprise the HPA axis create a feedback loop that releases hormones and then regulates the stress. Omega-3s, take a different approach. By crossing the blood-brain barrier, omega-3s (especially EPA and DHA) directly influence the brain and central nervous system cells, lowering cortisol levels and increasing protective compounds that otherwise would decrease under stress. Additionally, during stress episodes, EPA and DHA suppress the HPA axis, neutralizing oxidative stress. Read more here.

 

2. Omega-3s have an extensive amount of modern research behind them—more than 50,000 published studies, including 5,000+ human clinical trials, many of these featuring research on brain health (mood and mental focus), stress/anxiety, sports performance, sleep and fatigue and immune function. When it comes to scientific research, adaptogens do not have the same breadth of modern research, but they may also rely on “traditional history of use” (a health claim term under the law that acknowledges a long tradition of use of botanicals and herbs by ancient cultures in traditional medicine).

 

3. Another difference is that with adaptogens, the benefits may differ from ingredient to ingredient. For example, ashwagandha may help reduce anxiety and depression, whereas ginseng focuses on combatting fatigue. Tulsi (aka “holy basil”) is said to increase focus, decrease anxiety and boost the immune system while reishi mushrooms may help fight cancer and address the immune system. As for omega-3s, all those potential benefits mentioned above may be accessed from just omega-3s. However, the adaptogens may work more quickly (although you still may need two to four weeks of consistent, daily use); whereas with omega-3s, it is important to build up and maintain a store of EPA and DHA, for example, in your body as omega-3s work best when taken consistently over time, possibly several months and years. You want to reach an optimal Omega-3 Index level of 8-12%. (Keep reading. More on that to follow.)

 

4. Adaptogens take a more targeted approach, specifically focused on stress, or mood, or resilience, as examples. Omega-3s are more well-rounded nutrients with research showing potential benefit not only in adaptogen-related health categories (such as those just mentioned), but also supporting heart health, eye health, sports nutrition, pregnancy and cognitive health.

What the Research Says About Omega-3s and Stress

This article notes 17 health benefits of omega-3 fatty acids supported by science. For the purposes of this blog, we’re going to point you to #1, which references research that suggests those who regularly consume omega-3s are less likely to have depression and another study that finds omega-3 supplements may improve symptoms of depression and anxiety.

The lead author of this study noted findings suggesting “omega-3 supplementation is one relatively simple change people could make that could have a positive effect at breaking the chain between stress and negative health effects.” The researchers found that daily doses of 2.5 grams (the highest dose the study tested) of omega-3 supplements worked best at helping withstand the damaging effects of stress.

And although the authors said their findings were preliminary, the study showed that four months of omega-3 supplementation led to a profile of stress resilience—lower overall levels of cortisol and inflammation during stress, and higher levels of telomerase and anti-inflammatory activity during recovery. The authors suggested that if their findings were replicated, omega-3 supplementation may limit the impact of repeated stress on cellular aging and depression risk.

Not all omega-3 studies on stress showed benefit; however, enough did to warrant consideration of trying omega-3 supplements if you suffer from stress or anxiety. Engage your doctor in this conversation.

How to Optimize Your Omega-3 Status

The Omega-3 Index is a scientifically-recognized measurement and biomarker used extensively in scientific research that associates test results with clinical health outcomes. The Omega-3 Index is also a simple, finger-prick, at-home self-test, which you can order to determine your omega-3 EPA and DHA blood levels. Your results will report your omega-3 EPA and DHA levels as a percentage of your red blood cells.

Knowing your level is important because EPA and DHA are the main contributors to the health benefits associated with omega-3 fatty acids. Also, knowing your levels on the Omega-3 Index will help you determine whether you need to add more EPA and DHA in your diet and/or through supplementation.

An Omega-3 Index score of 8-12% is optimal, putting you in the lowest risk category for negative health outcomes and the sweet spot for potential beneficial health outcomes. If your test scores land between 4-8%, there’s room for improvement, while a score below 4% puts you in a high-risk category for health issues.
