omega 3 has several benefits in all over the body.
When possible, try to get omega-3 fatty acids from foods rather than supplements. Aim to eat fish two to three times a week.,well if you don't eat fish or food rich in omega 3 then yes you can take omega 3 without prescription
These include:
anchovies
bluefish
herring
mackerel
salmon (wild has more omega-3s than farmed)
sardines
sturgeon
lake trout
tuna
While eating more fatty fish is a good idea, some are likely to have higher levels of mercury, PCBs, or other toxins. These include mackerel, wild swordfish, tilefish, and shark.
Farm-raised fish of any type may also have higher levels of contaminants. Children and pregnant women should avoid these fish entirely. Everyone else should eat no more than 7 ounces of these fish a week. Smaller fish like wild trout and wild salmon are safer.Good food sources other than fish:
walnuts
flaxseed and flaxseed oil
canola oil
olive oil
soybean oil
While foods containing omega-3 fatty acids have health benefits, some -- like oils and nuts -- can be high in calories. So eat them in moderation.
