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

What are the capsule ingredients on the multi and omega 3 and All supplements Hi, the full ingredient lists can be found on all of our product pages. Scroll down to the central section and look under the 'Ingredients' heading. You can also download copies of the labels if required.
Hi! I was wondering why this product contains carrageenan wich in studies have proven inflammatory in the gut microbiome? There are products that can be used instead of carrageenan. Best regards Adelen Link to study: Hi, data relevance is everything. Carrageenan is completely inert and perfectly safe. We use a very small amount of high purity Carrageenan to help form our Omega-3 capsule. The article you shared repeatedly refers to Polygeenan, which is a low purity, degraded derivative of Carrageenan never used in human products, so is not relevant. The article makes some reference to animal data or lab-based results, both on significantly higher levels of carrageenan, and makes a clear and correct conclusion that it is not feasible to attribute the same results obtained in in vitro and/or in animal models to humans." We wouldn't use any ingredients if we had any concerns whatsoever about their safety. We use Carrageenan because it is perfectly safe and allows us to have a stable, vegan capsule. The alternatives are not as good, we have tried them.
I have severe arthritis and I can't have seafood. Does your omega 3 have the same benefits as the other omega 3 Hi, yes our Omega-3 products offer identical benefits to Seafood sources of Omega-3.
I have a question, as I recommend your omega 3 oil to most of my clients. There has been some recent research suggesting a possible link between fish oil supplements and an increased risk of heart conditions and stroke (see article below).Does it apply to algae-based supplements? Hi, the overwhelming evidence supports Omega-3s being beneficial in reducing the chances of heart disease and stroke, including helping to preventing existing heart conditions from worsening. We read the published report relating to Fish Oil with interest but its conclusion was pretty vague, effectively conceding the study in question didn't account for product types/formulations or doses, and the study used a very narrow participant base. It is certainly something we will monitor, but there is such a plethora of evidence into the positive health benefits of Omega-3s, based on much more robust research, we strong believe in their properties. Algal Omega-3 is certainly higher in purity than Fish Oil, with no other associated compounds in the product versus those items found in Fish. However, the study in question didn't really elaborate on the composition of Fish Oil either.
Hi there, I would like to order your vegan opti3 omega 3 capsules but I live in Portugal ad I can't see if you ship to here? Hi, yes we do and we have many customers in beautiful Portugal! We have a post-Brexit system where we cover any customs costs before the product reaches you in EU countries. If you experience any issues, our team is here to support.
Hi, I would like to know the expiration date of that product ? Thank you for your feedback. Hi, our Omega-3 products have a 24 month shelf-life.

    Vegetology are the only supplements that I will purchase. The Omega 3 has the highest levels of vegan EPA and DHA I can find, and they’ve added Vit D3 as a bonus. I’m so happy with these I’ve been taking them for seven years.

    They are amazing and fab! No repeating, no aftertaste, smell of gorgeous sea plant they are. Good value for money and will be and have been continuing to subscribe!!! The fact that the packaging breaks down environmentally within 10 years and can be recycled too is fab! No guilt with this product! My energy levels have increased as had my mood!
