Polyunsaturated Omega-3 fatty acids
Polyunsaturated Omega-3 (PUFA ω-3) fatty acids are essential nutrients that support overall human health. They are particularly found in fish, seeds, and nuts and play a key role in brain function, cardiovascular health, and neurological development.
Description
Polyunsaturated Omega-3 fatty acids are a group of essential fatty acids, including ALA (alpha-linolenic acid), EPA (eicosapentaenoic acid), and DHA (docosahexaenoic acid). They are termed “essential” because the body cannot synthesize them; they must be obtained through the diet. Omega-3s are known for their anti-inflammatory properties and their role in heart and brain health.
- Individuals with a history of cardiovascular diseases
- People with neuropsychiatric disorders (like depression)
- Those with inflammatory conditions or autoimmune diseases
- People following a vegetarian or vegan diet, who might not get enough EPA and DHA
- Pregnant or breastfeeding women, due to the role of Omega-3 in fetal and infant development
Omega-3 fatty acids are crucial components of cell membranes throughout the body and affect the function of cell receptors in these membranes. They provide the starting point for making hormones that regulate blood clotting, contraction and relaxation of artery walls, and inflammation. Omega-3s also bind to receptors in cells that regulate genetic function, which is why they are so crucial for brain function and development, as well as maintaining cardiovascular health.
A deficiency in Omega-3 fatty acids can lead to:
- Dry, itchy skin or dermatitis
- Poor memory, cognitive issues, or mood swings
- Fatigue
- Poor vision
- Heart problems
- Increased inflammation, potentially exacerbating symptoms of autoimmune diseases

The home test was straightforward with easy to follow instructions. The test result was detailed and clear in its presentation. Also had the opportunity to ask questions about the test result.

We looked at a lot of companies offering the same services but made the decision to go forward with get tested because the labs are based here in the UK. The process has been very straight forward.

There are other providers out there, I have tried 3. Gettested was the fastest and the customer service was the best. I even received my test on the day of purchase delivered by a motorbike courier.
