Omega 3 gets mentioned so often in health advice that it can start to feel like background noise, another supplement to add to the shelf without quite knowing why. Yet omega 3 fatty acids play a genuine, well evidenced role in brain, joint and overall wellbeing, and getting the basics right, what it is, how much you need and when to take it, can make a real difference. Here is what you actually need to know.
What Exactly Is Omega 3?
Omega 3 is a family of essential fatty acids that the body cannot make on its own, meaning they must come from food or supplements. There are three main types. Alpha linolenic acid, known as ALA, comes from plant sources such as flaxseed, chia seeds and walnuts. Eicosapentaenoic acid and docosahexaenoic acid, known as EPA and DHA, are found mainly in oily fish and algae [2]. The body can convert ALA into EPA and DHA, but this conversion is inefficient, which is why oily fish, algae oil or a good quality supplement tend to be far more effective ways of reaching adequate levels.
Why Your Body Needs It
DHA is a major structural component of the brain and the retina, while EPA is recognised for its role in reducing inflammation [4]. Ongoing research continues to explore the role omega 3 plays in supporting joint comfort, cognitive function and healthy ageing more broadly [4][5]. For many people over 40, this makes omega 3 one of the more worthwhile nutrients to get right.
How Much Omega 3 Do You Actually Need?
Health guidance in many countries points to a similar target, with recommendations commonly sitting around 250 to 500 milligrams of combined EPA and DHA per day for general wellbeing [3]. This is often translated into practical terms as eating at least two portions of fish a week, one of which should be oily fish such as salmon, mackerel or sardines, each portion being roughly 140 grams [1]. If oily fish rarely features on your plate, a supplement is a sensible way to help close that gap.
Food Sources Versus Supplements
Oily fish remains one of the richest natural sources of EPA and DHA, but it is not the only option. Algae oil offers a fish free source of the same active fatty acids, making it a reliable choice for vegans, vegetarians or anyone who simply prefers to avoid fish based products. Plant sources rich in ALA, such as walnuts, flaxseed and rapeseed oil, are a useful addition to a varied diet, though they should not be relied upon as a sole source of EPA and DHA given the limited rate of conversion in the body [2].
When Should You Take Omega 3?
Because omega 3 is fat soluble, it is best absorbed when taken alongside a meal that contains some fat, whether that is breakfast with eggs or yoghurt, or dinner with olive oil or avocado. Morning or evening both work well, and consistency matters more than the exact hour you choose. Taking your supplement with food also helps reduce the mild stomach upset some people experience when omega 3 is taken on an empty stomach. If you are new to supplementing, starting with a lower dose and taking it with your largest meal of the day is a sensible approach.
Choosing the Right Omega 3 for You
With so many formats available, choosing the right product often comes down to your diet and personal preference. For those who eat fish and want a concentrated, high strength source of EPA and DHA, Napiers' Lamberts Omega 3 Ultra Capsules deliver a leading dose per softgel, making them a popular choice for anyone wanting robust daily support.
For those following a plant based or fish free diet, Napiers' Catch Free Omega Capsules provide algae derived DHA and EPA, offering the same essential fatty acids without any fish content, alongside added vitamins D3 and K2.
A Simple Daily Habit Worth Keeping
Omega 3 is not a quick fix, but a nutrient that supports your brain and joints steadily over time when taken consistently. Whether you get yours from oily fish, algae oil or a well chosen capsule, the most important step is simply making it a regular part of your routine rather than an occasional afterthought.
Frequently Asked Questions About Omega 3
What is the difference between ALA, EPA and DHA?
ALA is a plant based omega 3 found in foods such as flaxseed and walnuts, while EPA and DHA are found mainly in oily fish and algae and are used more directly by the body, since the conversion of ALA into EPA and DHA is inefficient [2].
How much omega 3 should I take per day?
Guidance commonly points to around 250 to 500 milligrams of combined EPA and DHA a day for general wellbeing, often achieved through two portions of fish a week, one of which is oily fish [1][3].
When is the best time to take omega 3?
Omega 3 is fat soluble, so it is best taken alongside a meal that contains some fat, such as breakfast or dinner. Morning or evening both work well, as long as it is taken consistently.
Can vegans get enough omega 3?
Yes, algae oil provides a fish free source of EPA and DHA, making it a reliable option for vegans and vegetarians, alongside plant sources of ALA such as flaxseed, chia seeds and walnuts [2].
