Ingredients without impact

Omega‑3 sourced from microalgae

Most Omega-3 supplements are made from unsustainable fish oil, killing as many as 50 fish per bottle and transferring toxins from the oceans into each capsule - but the Omega-3 actually comes from the animal's diet of algae, not the fish itself. So, we've skipped the middle-fish and created a safer, more sustainable alternative from microalgae, grown in tanks at a specialist manufacturing facility.

Did you know?

The Omega-3 found in fish actually comes from their diet of algae, not the fish itself. Our Omega-3 contains EPA and DHA, the correct forms of omega-3 for the body to absorb and use, and the exact same forms found in fish. It's actually higher strength than most fish-based supplements!

3 reasons why fish oil alternatives are just as effective!

Your Questions Answered

Hi, is it allowed to take the opti 3 Omega 3 EPA& DHA during breastfeeding period? Kind regards Hi, yes absolutely. It is very beneficial to Mum and Baby throughout pregnancy and breastfeeding.
Also just curious how much vitamin E is in the EPA and DHA product? Hi, there is very little Vitamin (~1mg) in a daily dose of our Omega-3 EPA & DHA formulas. The Vitamin E is present solely to help protect the Algal Oil from oxidation during the production process. It is not present at a level designed to be nutritionally relevant.
Do you do third party testing and share your certificate of analysis? Hi, yes we use third party accredited laboratories for analysis, to meet European Food Safety Authority (EFSA) requirements. Everything is on file but we don't share in the public domain (nor does anyone tend to).
I have been taking 4 capsules a day. Is there any benefit to taking them split times in the day? Ie. 2 morning, 2 evening? I would like to ask this question of your Vollagen also. And other vitamins that require 2 tablets, like your Menopause multi and Bone Care? Thanks so much :) Hi, that's a really good daily dose of our Omega-3! We don't have any evidenced benefits of splitting intake across the day. Our view is that (other than Sleep-related supplements), it is always best to take supplements with breakfast or lunch. Vollagen is an interesting one because there may be benefits in taking it before bedtime to allow Collagen support overnight. We don't have any results behind that, but it's an interesting point that we will take a look into.
Hi there I had a few questions about your Omega 3. Having been looking at some of the other oils available on the market many of them actually all contain the same product which is called Life’s Omega which I believe comes from the US. I have been trying to find out the extraction process but haven’t been able to get a clear answer. You mention on your FAQ that your oils come from Europe and that your extraction process is clean so just wanted to check. Thank you! Jenny Hi, the extraction process for our Omega-3 Oil uses food grade enzymes (which are fully recovered). This is beneficial and 'clean' versus many other processes that include harsh solvents including Hexane.
What is the country of origin of the product components oils? Hi, we manufacture in UK. The oil components come from European sources

    Us herbivores finally have a POTENT dose of all proportions of Omega-3. There’s so many of these on market, with such little O3 / dodgy ratios - it’s almost pointless but Vegetology brings the substance in at its best. I’m already into taking it daily for around 2 months and I feel so present. My body feels different. I’m so excited to continue taking it! Thank you Vegetology.

    I have had osteo arthritis for over 28 years. I was taking strong pain killers for arthritic pain. Since taking the Bone Care tablets I feel good and have given up taking pain killers! I recommend these tablets to everyone suffering from pain.

    Fantastic and convenient.

    I wanted to start taking Omega-3 supplements as a possible way to reduce the frequency and intensity of my migraines. It was very hard to find non-fish supplements with high concentrations of omega-3s. This is the best I've found on the market in Europe! While it is too early to say if my migraines are less frequent, I can say that these supplements are easy to swallow and have no off-flavors. So far I am happy with them!

    Really pleased with these:) no nasty aftertaste like with the usual fishy omega 3! Thank You!

    Ive been taking these for a few years now. They are easy to swallow, no smell, and a good price. I never miss taking them as a vegan. I prefer to take these rather than rely on diet, its gives me confidence I am getting all my daily EPA DHA requirements, with no fuss. If I eat foods that are high in omegas I still take one of these capsules, if I dont eat foods on a particular day deemed high in omegas I take recommended two capsules a day. It works for me. My recent bloods show all normal as a vegan, so I am confident the supplements I take from Vegetology are working. Very happy I will continue using these and other supplements from this supplier.
