Size doesn't matter - well, at least when it comes to Omega-3 Fish Oil capsules. It's the active ingredients in each capsule that counts.
Although fish oil capsules come in various sizes such as 500mg and 1000mg, it's the amount of EPA & DHA in the fish oil that actually matters. So it's important that you read the bottle carefully to make sure your fish oil contains adequate strengths of EPA & DHA.
A capsule with low EPA & DHA will result in you having to consume large numbers of capsules to reach the recommended daily dose. A quick comparison of popular brands shows potencies range widely from EPA of 120mg to 590mg and DHA of 80mg to 370mg.
Generally speaking, a ‘standard’ 1000mg fish oil capsule contains 300mg active Omega-3s. For example, a label that states EPA/DHA 180/120 means it contains 180mg EPA & 120mg DHA for a total of 300mg Omega-3s.
A high quality fish oil capsule such as the Heartsmart.me 1000mg Omega 3 max is more concentrated with EPA/DHA 300/200. It contains a total of 500mg Omega-3s which means less capsules to swallow per day and usually a more cost effective way to obtain your daily requirement of Omega-3s.
