Have you tried it?
Only answer if you've tried Omega-3. What did it do for you?
What is it?
Omega-3s are fats found in foods including fish, nuts and seeds. Supplements commonly contain fish or algal oil, with EPA and DHA listed among the ingredients. People buy them for reasons such as heart health or eating little fish. Prescription omega-3 medicines also exist for specific uses.
A shop supplement is not interchangeable with a prescription product. Claims about eating fish cannot simply be transferred to a capsule. The promise you are paying for may be much broader than what is known about the product.

Survey answers are converted to these five answers. Each share above counts only the questionnaires that offered that answer, because not every survey offered all five. In Nootroflix (2022), a 10 out of 10 rating counts as “changed my life”.
What does it feel like?
There is no immediate sensation that confirms an effect on your heart or brain. Taking the supplement may feel like nothing in particular.
Fishy taste, burping, heartburn or an unsettled stomach may be what you notice. An unusually clear-headed day is not enough to attribute the change to a capsule.
What are the risks?
Digestive side effects and interactions with anticoagulants are possible. Some trials of particular treatments have found more atrial fibrillation, an irregular heart rhythm. A history of arrhythmia matters when considering use.
Addiction and withdrawal are not typical concerns. Composition, other medicines and the oil's source if you have allergies still matter. A heart-health label is not a substitute for reviewing those details.

Every answer makes this page more accurate. Share it with people who've tried Omega-3, whether it changed their life or did nothing for them.
Self-reported experiences, not medical advice. High scores mean people reported strong positive effects. They do not mean something is safe, effective long-term, or appropriate for you. Self-reports can miss delayed harms, dependence, withdrawal, side effects, and selection bias. Don't start or stop a medication because of a chart.
