Omega-3 fatty acids are a hot topic in health and wellness—and for good reason. These essential fats play a critical role in brain function, heart health and hormone balance, yet many people don’t get enough in their diets. If you’ve ever been confused about fish oil versus vegan options, wondered if you need an omega-3 supplement, not sure if you are getting any in your diet or feel overwhelmed by all the choices on the market, this guide is for you.
What Are Omega-3 Fatty Acids, and Why Do They Matter?
Omega-3 fatty acids are a group of polyunsaturated fats that are essential for the body. "Essential" means your body can’t produce them on its own, so you must get them from food or supplements.
The three main types of omega-3s are:
ALA (Alpha-Linolenic Acid): Found in plant sources like flaxseeds, chia seeds, and walnuts. The body converts ALA into the more active forms, EPA and DHA, but this process is highly inefficient.
EPA (Eicosapentaenoic Acid): Found in marine sources like fish oil, krill oil, and algae oil. EPA is known for its anti-inflammatory properties.
DHA (Docosahexaenoic Acid): Also found in marine sources, DHA is essential for brain and eye health.
Omega-3s support numerous functions in the body, including:
Reducing inflammation
Supporting heart health by lowering triglycerides and blood pressure
Enhancing cognitive function and reducing the risk of dementia
Promoting hormone balance
Supporting skin, nail, eye and hair health
Balancing mood and may reduce anxiety and depression
Fish Oil vs. Vegan Omega-3: What’s the Difference?
When it comes to omega-3 supplements, the two main options are fish oil and vegan alternatives like algae oil.
Fish Oil:
Contains both EPA and DHA, making it the most direct source of omega-3s for the body.
Often derived from fatty fish like salmon, mackerel, and anchovies.
Key considerations: sustainability, purity (free from mercury and other toxins), and potency.
Vegan Omega-3:
Derived from algae, the original source of omega-3s in the marine food chain.
A great option for vegetarians and vegans as it provides DHA and EPA without relying on fish.
Often more expensive than fish oil but equally effective when sourced properly.
Choosing between fish oil and vegan omega-3 depends on your dietary preferences and ethical considerations. Both can provide the essential fats your body needs if chosen carefully.
Signs You Might Be Low in Omega-3s
Many people unknowingly live with omega-3 deficiencies, as symptoms can be subtle or mistaken for other issues.
Common signs of low omega-3 levels include:
Dry Skin: Omega-3s help retain moisture, so a deficiency often shows up as flakiness or irritation.
Brain Fog: Difficulty concentrating or forgetfulness may be linked to low DHA levels.
Inflammation: Joint pain, stiffness, or swelling could indicate a need for more omega-3s to counteract inflammation.
Mood Swings: Studies have linked low omega-3 levels to depression, anxiety, and irritability.
Poor Heart Health: High triglycerides, hypertension, or irregular heartbeats might be exacerbated by insufficient omega-3s.
Fatigue and Low Energy: Low omega-3 levels can leave you feeling tired and low on energy because they help your cells function properly and support your body’s energy production.
If any of these resonate with you, assess your diet first then consider a supplement.
Do You Need Omega-3 Supplements, or Is Diet Enough?
While supplements can help fill gaps, food is always the best source of nutrients. Omega-3-rich foods include:
Fatty fish (salmon, sardines, mackerel)
Chia seeds and flaxseeds
Walnuts
Seaweed and algae (for plant-based eaters)
However, if your diet lacks these foods or you have higher needs (e.g. during pregnancy, menopause, or periods of intense physical activity), supplements can be a convenient and effective solution.
How to Choose the Right Omega-3 Supplement
Navigating the supplement aisle can be overwhelming, but a few key tips can help you make an informed choice:
Check the EPA and DHA Content:
Look at the back of the label to see how much EPA and DHA is provided per serving. Aim for at least 500-1000 mg combined per day.
Look for Purity and Quality Certifications:
Ensure the supplement is tested for heavy metals and contaminants.
Consider Sustainability:
Look for brands that source fish oil sustainably or choose algae oil for an eco-friendly vegan option.
Buy what you can afford:
Opt for the best quality your budget allows.
My favourite brands are Nutri Advanced and Bare Biology
Avoid Fillers and Additives:
Stay away from supplements with artificial flavors, colors, or unnecessary fillers.
Consult a Professional:
If you’re taking medication or have health concerns, consult a nutritionist or healthcare provider before starting omega-3 supplements as they made interact with current medications.
Omega-3 and Hormone Health
For those navigating hormonal changes—like menopause, PMS, PCOS, disrupted or heavy periods, thryoid conditions - omega-3s can be supportive. These fats:
Reduce inflammation, easing joint pain and muscle stiffness often experienced during menopause.
Support mood stability by aiding neurotransmitter function in the brain.
Balance hormone production by reducing excess inflammation that disrupts hormone signaling.
Adding omega-3s to your diet or supplement routine may help manage these symptoms more naturally.
