All fish oil are good, just make sure you check the source of the fish oil (I ever see a brand fish oil that state the source of it is "sea creature"). But the best one is from the deep sea fish or fish that live in cold
places, such as salmon. Such fish oil is a good source of omega 3. If possible, choose fish oil with d-alpha tocopherol
(natural vit e) as it will act as antioxidant and prevent the fish oil to loss it potency. However, do take note that ppl who are consuming high blood pressure medication
should ask for doctor advice
before they start taking fish oil as fish oil is a natural type of blood thinner.
P.S you may add "COq10 with taurine" for the heart health also.
