Consider the form of the supplement
Fish oil comes in softgels and liquid forms. Softgels are easier to swallow and have less fishy taste. Liquid forms may require measuring but can be easier to digest.
Evaluate the daily dosage
Check how many softgels you need per day. Some options may require taking two or more to reach the recommended omega-3 levels. Choose a product that fits your daily routine.
