Is it better to take fish oil in the morning or at night?
Because most of the benefits of fish oil are associated with long-term use, you can take it at any time of day. That said, splitting your supplement into two smaller doses in the morning and at night can reduce acid reflux.
Why does it take so long for omega-3 to work?
While it takes only three to four hours for the omega-3 fatty acids to reach your blood after taking your supplement, the long-lasting effects can take longer to appear. This is because the fatty acids first saturate your blood, before starting to slowly build up in your tissues, where they are especially needed.
How long does it take fish oil to get out of your system?
Omega-3s stay in your system anywhere from about six weeks to six months. The amount of omega-3s that stay in your system also depends on the amount you receive through diet or supplementation.
