Putting even more 'good' into 'good fats', our 100% natural Vegan Omega-3 is created directly from microalgae grown in tanks at a specialist manufacturing facility, offering all the benefits of fish oil Omega-3 without the safety, sustainability or purity concerns associated with fish sources. It provides a high dose of EPA and DHA, the bioavailable forms of Omega-3 that the body needs for optimum absorption.

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 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.
Hi! I would like to know which type of algea is specifically used? The package just says „microalgea oil“. I would be interested what kind of other nuctricions the type of algeas provides additionally, for example B12. I am especially asking since I need to avoid certain nutrients. Thank you. Hi, we use Schizochytrium species. It is an oil extract from a microalga (rather than an alga / seaweed), so doesn't carry through other nutrients such as B12.
I have 14 year old child with ADHD - what’s the maximum dose of your vegan omega can I give him? Thanks in advance Hi, our recommendation for your Child is 2 x capsules per day. In Europe the set maximum recommended level for Omega-3 (combined DHA & EPA) is 5000mg. That would be the equivalent of approximately 10 capsules. We hope our formula helps and would love to hear your feedback.
He leído que el Omega 3 es bastante oxidativo en contacto con luz y oxígeno, ¿Las cápsulas y el bote son opacos? Gracias. Hi, oxidation is a problem for Omega-3 but we take many steps during production and within the formula to address this. Light is not a problem for Omega-3 stability.
I am in search of omega 3 vegan that is not rancid which is actually hard to find!What steps do you take to help with rancidity of this supplement Hi, our Omega-3 formulas are produced under very careful conditions to ensure oxidative stability, and also contain natural antioxidants. We rigorously stability test to ensure stability throughout and beyond the stated shelf-life.

    We’ve been using Vegetology products for several years and are delighted with the products and with the customer service. Wonderful to be able to purchase ethically sourced vegan products and to be able to obtain advice from a knowledgeable team. We share the Omega 3 supplements with our two greyhounds where we use this in the nutrient dense icing for their home cooked food as per the instructions of Dr Arielle Griffiths - vegan vet. Their fur is amazing!
