Food Allergies & Intolerance

Fish and Shellfish Allergy

A fish allergy occurs when your immune system mistakes fish proteins as harmful and produces antibodies in order to neutralise these proteins. Once released within the body, these antibodies cause a reaction that leads to an increase in the production of histamine. Release of histamine and other inflammatory mediators, leads to common allergy symptoms such as inflammation and irritation of the soft tissue of the skin.

The greatest risk from fish allergies is anaphylaxis. This can cause life-threatening breathing, cardiac, and gastrointestinal symptoms. Fish allergy is considered one of the most common food allergies. It is also less likely than other allergies to be outgrown. Although other common food allergies may be outgrown, this is much less likely with fish allergy due to its severity.

Fish allergy and our Omega 3 capsules

*Our Omega 3 is ONLY made from algae; it is a totally NON-FISH, NON-ANIMAL source of long chain Omega 3 EPA & DHA. Even the capsule shell is vegan. There are no harmful proteins within our algal oils and therefore there are unlikely to be associated risks with our algal oil and fish, shellfish allergy or intolerance.


*Always consult your doctor before taking any supplements.

Other vegan Omega 3 supplements

If you are not able to consume fish due to a fish allergy, you may have already considered a vegan or vegetarian Omega 3 alternative to fish oil supplements. Beware, not all Omega 3's are equal. Unfortunately, manufacturers are not obliged to make the distinction between short chain omega 3 (ALA) and long chain Omega 3 (EPA, DHA) polyunsaturated fatty acids (PUFAs) on their labelling. So when you see 'contains Omega 3' on a label, look for EPA, DHA.

Short chain PUFAs are obtained from walnuts, soy, flax oil, hemp oil and many other land based foods. They require conversion within the body to long chain Omega 3 (EPA, DHA) in order to be of benefit in building and maintaining healthy eyes and brains .

There are only two superior sources of long chain Omega 3 (EPA, DHA) and these are; fish oil and algae oil.


Our Algal oils does not contain iodine, people with shellfish allergy are often warned against iodine intake. Iodine is an element present in a wide range of items including seaweeds and shellfish. However, iodine allergy is unrelated to shellfish allergy. The allergen present in shellfish is not iodine but protein in the flesh of the shellfish or fish.

Avoid Fish Oil Omega 3 Supplements

Fish oil Omega 3 supplements are not recommended for people with a fish or shellfish allergy because fish oil and cod liver oil supplements may still contain small amounts of fish proteins even when these proteins have been removed from the oils supposedly. Algae oil has 0 % of any fish product or by product 


Fish and shellfish allergy symptoms can include minor symptoms such as : sinus congestion, sneezing, a runny nose, coughing, nausea, vomiting, diarrhoea, stomach cramps, wheezing and asthma, shortness of breath, tingling in the skin and skin rashes. More serious symptoms include, generalised eczema, swelling of the lips, face, tongue, throat, itching, hives, nausea, vomiting, diarrhoea, fainting, trouble with breathing, dizziness and abdominal pain, rapid heart rate and a drop in blood pressure. The most severe is a condition known as anaphylaxis which can cause life-threatening breathing, cardiac, and gastrointestinal symptoms.

Food Intolerance and Food Allergy

Sometimes it's difficult to know whether you have food allergy or intolerance. Often the symptoms are similar, such as feeling unwell, diarrhoea, vomiting, gastrointestinal pain and fever. There are some symptoms which you often get only in food allergies and not in food intolerance.

Your doctor is the best person to advise you as to whether you have a food allergy, food intolerance or another condition, and what treatment you need.

Our Omega 3 supplements and Food Sensitivity

Our algae-derived EPA DHA capsules are free from wheat, sugar, gluten, dairy all animal products and by-products.

We add a small amount of Vitamin E; this acts as a natural anti-oxidant and preservative. Generally we have found that people with allergies don't have any problems when taking any of our Omega oils.
