Omega 3's are crucial for brain and heart health, and they are found naturally in fish and shellfish. However, if you either do not like the taste of fish, or can't have much of it due to high cholesterol, a fish oil supplement is the way to go. This supplement does have a fishy smell to it, but I've yet to come across one that doesn't (even the GNC brands smell/taste fishy). It isn't overwhelming, but if you absolutely hate the smell of fish, you may want to find a better option to get your Omega 3's in, such as using plant-based capsules.
This 180-count bottle only costs $30 on Amazon, and is a three-month supply, which I think is a pretty good deal. It is recommended to take 2 capsules daily, but I usually only take one per day because I like and incorporate seafood into my regular diet, and to stretch my bottle out longer. It is not recommended to take more than 2 capsules per day.
