Why are liquid fish oil doses for my dog higher than gel caps?

Updated On September 23rd, 2025

Why do liquid fish oils recommend twice to triple the dose of gel cap fish oils? Just curious. Is it because they presume the liquid fish oils will go rancid faster. RX vitamins isn't a pump bottle it's a flip top, so I'm assuming it doesn't go rancid as fast. Is this true or will it go rancid faster? If I give half the dose will she still be getting adequate amounts of omega 3? Thanks! I like Nordic naturals but I like that RX vitamins has added vitamin E, minerals and omega 6.

I think it has more to do with the amount of EPA and DHA per serving. With the liquid, there's likely less of these fatty acids per serving so it requires more of the product to get the recommended daily amount. Even half the amount will still be beneficial, and it's fine to do less than recommended. That's because too much fish oil can have detrimental effects on the dog's body, such as interference with wound healing. Recommended daily levels are typically low enough to prevent this from occurring, but having less than recommended is fine :-)
