What Happens When You Take Fish Oil for 90 Days?
Fish oil mainly provides omega-3 fatty acids (EPA and DHA). Taking it for 90 days doesn’t produce the same effect in everyone, and benefits depend on your diet, dose, and health.
Over roughly three months, you may see:
-
Lower triglycerides — This is one of the best-established effects of sufficiently dosed EPA/DHA.
-
Changes in omega-3 levels — EPA and DHA become incorporated into cell membranes and blood levels can rise with regular supplementation.
-
Possible cardiovascular effects — Benefits depend heavily on the specific product and dose. Prescription-strength omega-3 products are different from ordinary supplements.
-
Little or no noticeable change — Many people won’t feel different even when blood lipid levels change.
-
Digestive side effects — Fishy aftertaste, burping, heartburn, nausea, or diarrhea can occur.
-
Potential interaction with medications — Particularly important if you’re taking anticoagulants or antiplatelet medicines or have a bleeding disorder.
-
Possible increase in atrial fibrillation risk at higher doses — Some clinical trials have found an increased risk of atrial fibrillation with certain high-dose omega-3 treatments, especially in people with cardiovascular disease or risk factors.
Is 90 days enough?
It can be enough time to see a measurable change in triglycerides and omega-3 status, but fish oil isn’t a general-purpose treatment that everyone needs. Eating oily fish such as salmon, sardines, or mackerel as part of a balanced diet is often a good way to obtain omega-3s.
If you’re considering fish oil specifically for high cholesterol, high triglycerides, heart health, or another condition, the appropriate dose and whether you should take it at all can be quite different.
