What Happens When You Take Fish Oil for 90 Days?
Fish oil supplements provide omega-3 fatty acids (EPA and DHA). After about 3 months, some people may notice benefits, while others may notice little change. The effects depend on your diet, health conditions, and the dose.
Possible benefits
❤️ May lower triglycerides
Fish oil is most effective at lowering high triglyceride levels. Prescription-strength omega-3 products can reduce triglycerides substantially when prescribed by a healthcare professional.
🫀 May support heart health
Eating fish regularly is associated with a lower risk of heart disease. Fish oil supplements may benefit some people, but they are not a substitute for a healthy diet or prescribed medications.
🦴 May help joint symptoms
Some people with inflammatory conditions, such as rheumatoid arthritis, experience modest improvements in joint pain and stiffness.
🧠 May support brain and eye health
Omega-3s are important for normal brain and eye function, but evidence that supplements improve memory or prevent dementia in healthy adults is limited.
Possible side effects
- Fishy aftertaste or “fish burps”
- Upset stomach
- Nausea or diarrhea
- Bad breath
High doses may increase the risk of bleeding, especially if you’re taking blood-thinning medications.
Who should talk to a healthcare professional first?
- People taking blood thinners (such as warfarin, apixaban, or rivaroxaban)
- People with a bleeding disorder
- Anyone with a fish or shellfish allergy
