Salmon oil supplements contain a concentrated form of the oil from salmon. They are rich in healthy fats that have numerous health benefits.
Fish oils, such as salmon oil, may benefit the skin, hair, brain, and general health, largely due to their high content of omega-3 fatty acids.
This article reviews the many benefits of taking salmon oil supplements, plus a few things to consider.
Salmon oil and salmon oil supplements may provide several important health benefits.
Rich in omega-3s
The potential health benefits of salmon oil mainly come from its
Scientists consider these to be healthy fats and believe they may benefit overall health.
These types of fats come from the diet, largely from seafood.
Taking salmon oil supplements may be a helpful way for those who do not eat much seafood to get these healthy fats. Consuming omega-3 fatty acids may have a number of benefits.
Excessive inflammation is a marker of a number of chronic diseases and may increase the risk of many diseases over time.
Omega-3 fatty acids help reduce inflammation in the body.
A study posted to Biochemical Society Transactions notes that there are a few different actions of omega-3 fatty acids in the body. They appear to block markers of inflammation and disrupt signaling centers in the cells. These combined effects may help reduce inflammation in the body.

It may be best to begin taking supplements early because they may be most effective for preventing disease when the brain is still healthy.
That said, research has found conflicting results about the effects of taking omega-3 fatty acids on major disorders, such as Parkinson’s and Alzheimer’s disease. Scientists need to do more high quality human trials on these topics.
The benefits of fish oils stem mainly from their high concentration of omega-3 fatty acids, including DHA and EPA.
The actual content of these oils in any given supplement will vary based on numerous factors, such as where the salmon came from,
Other oils, such as krill oil or algal oil, may be similar in quality to salmon oil.
Check the supplement label to see how much EPA and DHA a supplement contains per recommended dose.
Salmon oil supplements increase the levels of important omega-3s in the body. These are essential nutrients, meaning the body cannot make these compounds — they have to come from the diet.
Omega-3 fatty acids themselves are widely useful. Research posted to
This includes cells in nervous tissue, the heart, and the retina. Along with other helper compounds, omega-3s even cross the blood-brain barrier.
The dosage of salmon oil supplements varies based on the manufacturer. In many cases, a person can use the product as the label directs.
The dose the labels recommends can vary, and may range from 100 mg to more than 1 g. Doses can go as high as 3 grams, but a person should only use these under a doctor’s direct guidance.
Always work with a doctor and follow any specific instructions they provide on personal dosage limits.

Higher doses may interfere with how the blood clots and a person may experience nosebleeds or may bleed easily. This may also cause an interaction with some drugs, such as blood-thinning medications or drugs for high blood pressure.
In sensitive people or at very high doses, salmon oil and omega-3s may lower the body’s immune response.
People with allergies to seafood may need to avoid salmon oil.
There is some concern about the risk of fish becoming contaminated due to environmental chemicals, heavy metals, and pollution. Anyone concerned about this may want to check with the supplier of the salmon oil supplement.
