No/Yes: Most anything can be harmful if taken improperly. Think about it, drinking too much water can make you very ill or you can die. Fish oil, like anything else should be taken according to manufacturer's directions or according to your health care provider. Fish oils have many beneficial effects if used properly and if a reputable product is purchased. Some fish oils are alleged to be contaminate.

Possibly: 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".

Fish oils the contain DHA raise LDL cholesterol, fish oils that contain only EPA decrease LDL cholesterol, in addition to lowering triglycerides

Harmful fish oil: Most fish oils are sold as dietary supplements and are not tested or approved by the fda.

Check brands 4 safeT: Fish oils can go rancid, and then not be safe to use. So, it's best to check the brands and find the ones that are considered high quality, and recommended by many integrative medicine, internal medicine, family medicine physicians, and those, who understand the nutritional value of fish oils (omega 3's) to reduce inflammation, and protect myelination of nerves. Nordic naturals are popular. Stay away from gnc.

High cholesterol: Fish oil is high in omega-3 fatty acids. These are good for lowering your LDL cholesterol and your triglycerides and improving your cardiac health. Red krill oil has the same benefits without the fishy taste or fishy burps.

4 signs: 1- the container is not past expiration, 2- the capsules smell only slightly "fishy, " 3- the capsules are a pale yellow color, and 4- the capsules are firm to light pressure. If all four of these qualities are present, the capsules are likely fresh.

Depends on how much: The scientific evidence suggests that fish oil really does lower high triglycerides, and it also seems to help prevent heart disease and stroke when taken in the recommended amounts. Ironically, taking too much fish oil can actually increase the risk of stroke
