What is Omega 3?

Omega 3 is one of the ‘essential fats’ best known for being good for your joints, brain and heart. When most people think of Omega 3 sources, or sources of fat, they think of fish. We’re pleased to inform you that there are vegan sources of Omega 3 too!



Omega 3 supplements are a great addition for a healthy diet, however, until they discover Vegetology, many of our customers don’t realise that sources of Omega 3 can be vegan or vegetarian. Our vegetarian Opti3 contains EPA and DHA, the correct forms of omega-3s for use by the body and the same as those found in fish. How much Omega 3 do you need? Well, Opti3 is actually higher strength than most fish-based supplements! A bottle of Opti3 saves at least 35 fish compared to an equivalent bottle of fish oil omega-3!

Opti3 versus Flaxseed Oil

When it comes to foods high in Omega 3, there is no comparison! Flaxseed provides the body with omega-3 in the far less effective form of alpha-linoleic acid (ALA). ALA is not equivalent to DHA or EPA in its biological effects, and needs to be converted to EPA in order to be effective, but this conversion rate is incredibly low.

Opti3: vegetable-sourced Omega-3 fatty acids

Oily fish is probably one of the most well known Omega 3 foods and are undoubtedly a rich source of omega-3 EPA & DHA, but this is actually due to their diet of algae. Our exclusive Opti3 complex is a novel combination of algae and plant-based ingredients to provide the body with proven levels of EPA & DHA together with a dose of vegan Vitamin D3.

Suitable for Vegetarians and Vegans

One of our favourite supplement solutions, Opti3 is designed to be literally suitable for everyone! This includes use during pregnancy and breast feeding. One of the main aims of the Opti3 Omega 3 supplement is to provide effective omega-3 nutrition to supplement vegetarians and vegan diets. We are proud to be registered with the Vegetarian Society and Vegan Society.


As a vegan Omega 3 supplement, Opti3 offers all of the many benefits of Omega-3 from a 100% vegetable source, taking away any of the safety or purity concerns associated with fish sources. What does Omega 3 do? It contributes to good heart, brain, joint and eye health and more - and that’s just for starters. Opti3 is:

  • Great for kids, great for you
  • Perfect for use during pregnancy
  • 100% non-fish, non-animal
  • Heart, brain, joint, eye health and more
  • Far superior vs Flax Seed
  • Purity and sustainability guaranteed


So, how much Omega 3 a day? For best results take 1-2 capsules per day with food.

  • After a year or so of becoming a vegetarian, I had a check-up and my triglycerides were high. The doctors told me it was unusual for a vegetarian to have this condition and the only thing they advised me that I wasn't already doing was to take more omega-3. I found this product and I took them for 6 months and my triglycerides went from almost 300 to little over 100. Another thing: you can take the whole capsules, chew it or pierce it and add the oil to food. It tastes like seafood grown on the rocks (e.g. barnacle). I liked it.

  • Such a great product, vegan and plant-based (instead of artificial), and at such a great value, especially with the bundle offers. Thanks Vegetology! -`

  • Love this brand. I did some research and I have tried a few other brands too. Vegetology in my opinion is the best. They are one of the only brands to use a vegan D3 source, registered by Vegan Society, use pure ingredients; designed and researched by vegans who are professionals in their field; offer fantastic discounts and their multiple vitamin has all the essential ingredients I have researched. Would highly recommend them. I use both the Omega Opti 3 and Veg Vit

  • Very fast shipping, but sadly the capsules are too big for me to swallow.

  • This product is a blessing for we vegetarians/vegans who want a high strength supplement that contains clean dosages EPA & DHA and will actually have a positive effect on health. In a number of weeks I've noticed a drastic change in my skin that was displaying signs of an omega3 deficiency. It's back to normal, with no dryness or irritation and my eyes are no longer burning. I also feel more energised. This supplement is proving its worth. Keep up the good work Vegetology in sustaining an ethical practice and quality product!
