The Claim
Omega-3 products in capsule and chewable forms maintain sensory quality (absence of detectable rancid odor or taste) for a longer duration under storage conditions compared to syrup forms, with syrups exhibiting rancid odor by day 14 and rancid taste by day 35.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Omega-3 supplements in capsule or chewable form stay fresh longer than syrups when stored, as syrups develop a rancid smell by day 14 and a rancid taste by day 35.
See the scientific wording
Capsule and chewable omega-3 products maintained sensory quality (no detectable rancid odor or taste) longer than syrups under storage, with syrups developing rancid odor as early as day 14 and rancid taste by day 35, indicating that packaging form influences consumer-perceived freshness.
The hard shell of capsules and chewables blocks air and light from reaching the omega-3 oil inside, so the oil doesn't break down into bad-smelling and bad-tasting chemicals. Syrups are exposed to air and light directly, so the oil breaks down quickly and produces those unpleasant smells and tastes.
What the research says
1 studyStudy: Effect of packaging and encapsulation on the oxidative and sensory stability of omega‐3 supplements
The study found that omega-3 capsules and chewables stayed fresh longer than syrups when stored, because the capsule shell protects the oil better from air and light, which cause bad smells and tastes.
