A single serving (1 tablespoon or 15 milliliters) of fish liver oil provides more than the recommended daily intake of omega-3, vitamin D, and vitamin A.
However, it’s not recommended to consume more than one serving per day, as too much preformed vitamin A can be dangerous for your baby. High levels of omega-3 may also have blood-thinning effects.
Low mercury fish like salmon, sardines, canned light tuna, or pollock can also help get you to your omega-3 goals.
