An ingestible composition contained in a soft gel or shard shell capsule includes a digestible odoriferous oil such as a fish oil which can cause reflux or eructation odor problems on the breath of a person taking the capsule. This is reduced by including in the ingestible composition at least one surfactant, preferably in an amount of about 2 to about 20% weight and at least one edible odor-masking ingredient such as parsley seed oil, lemon balm, lemon grass oil, fennel, peppermint oil and/or menthol.
