    Ask what the manufacturer changed

    A product may use flavoring, a coating or another formulation approach to address fishy aftertaste. The word burpless alone does not identify the mechanism or guarantee that every user avoids reflux. ODS lists unpleasant taste and gastrointestinal symptoms among possible omega-3 supplement effects. [1][2]

    Do not confuse taste with purity or efficacy

    Less noticeable aftertaste does not establish a higher EPA/DHA amount, lower contaminant level or a better clinical outcome. Compare the nutrient amounts and any product-specific testing separately. The tolerability feature can matter to the user without proving superiority on every other measure. [1][3]

    Follow dosage-form instructions

    Imagine a capsule uses a special coating. Opening or altering it may defeat the intended delivery, so follow the product directions or ask a pharmacist about an alternative form. If reflux persists, do not simply increase the dose because the package promised burpless use. [2][1]
