What is a safe amount of 1000 mg of fish oil you can take in a day?

4 capsules: The usual dose is 2 capsules of 1000 mg taken twice a day. More is not likely to cause harm but may not do any more good either.

None: Krill oil and fish oil are the new snake oil, both are high in omega 3 fatty acids which are extremely fragile. Omega 3 fish oils reduce triglycerides by impairing the liver's ablility to make them. However the oxidative stress caused by fish oil actually raises LDL cholesterol. Some day we may use the phrase "this is just more fish /krill oil" or "here comes the fish/krill oil salesman".
