    Omega-3 from algae

    Oily fish are the most common source of omega-3. But did you know that fish don't actually make omega-3 themselves? They get it from eating a specific type of marine algae found in coastal mangrove forests.

    We get our omega-3 from the same source, by farming the algae in purified water and extracting the natural omega-rich oils.

    Not only is this kinder to the fish and more sustainable for the planet, but the oil is completely free of the heavy metals and toxins commonly found in seafood.

    algae oil vs fish oil vs flaxseed oil

    Fish oil and cod liver oil might spring to mind first when you think of omega-3, with flaxseed oil as a common plant-based substitute.

    But how do these sources truly stack up against each other? Let’s unpack the facts and find out why algae oil comes out on top.

    frequently asked questions

    Omega-3 plays a role in cells throughout the entire body and can therefore produce numerous benefits.

    It's best known for heart, brain, and eye health. It is also a crucial nutrient for pregnant and breastfeeding women as it plays a role in the development of the growing baby.

    Omega-3 also promotes an anti-inflammatory response in the body, helping to defend against many inflammatory diseases. 

    Benefits which have been noted by our customers include:

    • Improved memory and concentration
    • Better quality sleep
    • Improved general mood
    • Reduction of dry eyes and redness
    • Reduced symptoms of rheumatoid arthritis
    • Improved joint mobility
    • Clearer, softer skin
    • Healthier hair and nails
    • Improved eczema
    • Improved behaviour in children

    We actually offer two versions of our Omega-3 - the original and Omega-3+

    Our original Omega-3 product is DHA only. The main reasons for taking this approach were value-for-money, capsule size and the fact that DHA is the real powerhouse of the Omega-3 family.

    We thought it would be better to offer a really good dose of DHA in a small capsule, making it more affordable for many people.

    Having said that, our Omega-3 Plus and Omega-3 Plus Liquid are great options for those customers who do want the extra EPA. It took us quite some time to develop as we wanted to include the EPA without increasing the size and shape of the capsules. 

    DHA is the most difficult Omega-3 for the body to produce, which is why it is particularly beneficial in supplement form. Although EPA is certainly an important Omega-3, studies have shown that people with a balanced diet rich in DHA can produce enough EPA naturally.

    Whilst DHA and EPA have both have been shown to reduce inflammation, DHA is responsible for most of the benefits in relation to brain and eye health.

    Based on our research, we think a high-quality DHA supplement is the best value for money for most people, but we also offer options for people who specifically want the extra dose of EPA.

    Our Omega-3 is created with safety and quality as the top priority. Our manufacturing is certified to meet GMP, BRC Global Food Safety and ISO 9001:2015 standards.

    Each batch is independently tested for heavy metals and microbes and our formulation is 100% GMO-free.

    We are also transparent about our ingredients to ensure your peace of mind.

    Omega-3 is an extremely important nutrient for a growing child due to its role in brain function and development.

    The algae oil itself is suitable for children, however we do not officially recommend Omvits Omega-3 capsules for younger children due to the potential choking risk. Therefore we leave it to the parents' discretion.

    If your child has trouble with capsules, we also offer Omega-3 for Kids (for children aged 3 months to 6 years) and Omega-3 Plus Liquid (suitable for children aged 6+).

    As with any health supplement, you should always consult a doctor or paediatrician first.

    Yes, absolutely. In fact, pregnant and breastfeeding women are likely to get the most benefit from our Omega-3. In addition to a normal daily intake of Omega-3, pregnant women require an additional boost of DHA for the normal development of the brain and eyes of their growing baby.

    The European Food Safety Authority (EFSA) recommends a minimum daily intake of 250 mg of Omega-3 per day for an average adult, with an additional 200 mg of DHA per day for pregnant or breastfeeding women. Studies have shown numerous benefits of DHA intake for the health of both mother and baby. 

    As with any health supplement, you should always consult a doctor first.

    Not all Omega-3s are created equal. Without getting into the science too much, there are three main types of Omega-3: ALA, DHA and EPA.

    Supplements derived from seeds are rich in ALA, but contain no DHA or EPA. Although ALA is good for your health, it is far less effective than DHA and EPA, which are responsible for the majority of the health benefits associated with Omega-3. Your body can convert some of the ALA into DHA and EPA, but not nearly enough for optimal health.

    Omvits Omega-3 is rich in DHA, which is especially important for heart, brain and eye health, as well as foetal development during pregnancy. 

    This makes it a much better option to seed oils to meet your daily Omega-3 requirements.

    Omvits Omega-3 may be particularly beneficial for:

    • Vegetarians, vegans or anyone with very little oily fish in their diet
    • People concerned about the sustainability issues around fishing
    • Pregnant and breastfeeding women
    • People over the age of 50 who are at higher risk of cardiovascular disease, cognitive and visual decline or joint pain
    • People with seafood allergies
    • People who suffer from dry eyes
    • People wanting to improve their concentration levels and memory
    • Young children
    • People wanting to improve the health of hair, skin and nails

    No this does not contain Omega-6. Although Omega-6 is an important fatty acid, the modern diet is very rich in Omega-6. In fact, most people consume far too much, to the point that it is affecting our health.

    The ideal ratio of Omega 3 to 6 in the diet is 1:1, while is reality it is closer to 1:20 in the western world.

    For this reason, we did not include any Omega-6 in our products as there is little health benefit to supplementing with it.

    In most cases, it's far better to increase your Omega-3 and reduce your Omega-6.

    You may think that a supplement which contains Omega 6 and 9 as well as Omega-3 is a better choice than Omega-3 on its own.

    However, most of us already get plenty of Omega-6 from the foods we eat. In fact, we are eating so much Omega-6, that it is having a negative effect on our health by causing inflammation.

    By taking a supplement with added Omega-6, you could be damaging your health further. As for Omega-9, this is not required in our diet at all. Omega-9 is a “non-essential” fatty acid, as it can be created by the body from other nutrients.

    It's far better to get a high quality Omega-3 supplement.

    There is no official standard for how much Omega-3 we should get each day. However, most health organisations agree that 250–500 mg per day is sufficient to maintain good overall health.

    One such organisation is the European Food Safety Authority (EFSA), who recommend the following:


    - 250 mg DHA or EPA per day for normal adults

    Pregnant/breastfeeding women:

    - 200 mg DHA per day in addition to normal adult requirements (450 mg total).

    Children (3-24 months):

    - 100 mg DHA per day

    Children (2-18 years):

    - 250 mg DHA or EPA per day

    There is no doubt that fish oil has some health benefits, however, there are also well documented downsides. If you are considering buying a fish oil, here are a few things to bear in mind:

    1) Many fish oils are cheap, but you should be aware of what you are paying for. These cheap fish oils are regularly of poor quality and contain relatively small dosages of DHA/EPA. They often have not been properly processed to remove heavy metals and toxins. You'll also find that they have a very strong "fishy" smell or taste. This is because the oil is starting to go rancid as the polyunsaturated fats start to go bad.

    2) If you saw how fish oil is made, you probably wouldn't want to put it in your body! Fish scraps are mashed, steamed and squeezed to get the oil out before it goes through further processing.

    3) Our seas are more polluted now than they have ever been. Fish often contain harmful levels of contaminants and toxins including heavy metals, PCBs and dioxins. High levels of these substances in your diet can have serious health consequences, particularly for pregnant women.

    4) There are major concerns about the impact of overfishing on world fish stocks. According to the United Nations, world fish stocks are expected to collapse by the year 2048 if current practices continue. Algae on the other hand, is fully sustainable and a great alternative to fish oil for vegans and non-vegans alike.

    5) Fish is a highly inefficient way of getting Omega-3 in comparison to algae. Pound-for-pound, algae contains approximately twenty times the amount of Omega-3 as fish. In other words, for every 20 kilograms of fish taken out of the ocean, you'd only need 1 kilogram of algae to produce the same amount of Omega-3!

    Our algae is grown in a closed system in purified water and not taken from the sea.

    Not only does this mean that the algae is completely free of ocean-borne contaminants, it also doesn't disrupt the delicate marine eco-system.

    actually good!

    Honestly, what a great product. Omegas from algae, who knew. I crunched one in my mouth and it tasted fresh! Good product, thanks guys.

    Price, strength and quality

    I have bought and consumed Omvits ‘Omega 3 from algae, not fish’ for the last few years. Each time I need to get some more, I always shop around but find the Omvits product is always the best value for money for 400mg of DHA. They are easy to take with absolutely no aftertaste. I am allergic to fish so this is the ideal product for me! This is a sustainable product not depleting fish stocks and free from plastics and toxins that can sadly get concentrated in the fish. Delivery is really quick and I wholeheartedly recommend them to all my friends!
