Why Blister Packaging Protects Omega-3 Capsules from Heat and Cold Damage

Omega-3 softgel capsules are sensitive to extreme temperatures during shipping and storage. Whether exposed to high summer heat or winter cold, improper packaging can lead to product degradation. That’s why premium blister packaging is essential for maintaining the quality, freshness, and efficacy of your omega-3 supplements.

Heat Damage in Summer

When omega-3 capsules are shipped during hot summer months, they may be exposed to temperatures above 30 °C (86 °F). At this point, the gelatin shell can soften, deform, and leak a small amount of oil. This oil, once exposed to oxygen, begins to oxidize and turn brown. Over time, the entire surface of the softgel may darken.

In bottle packaging, this leaked oil can spread, contaminating dozens of other capsules. The result? A strong rancid fish smell and discolored, compromised capsules throughout the bottle. Once this happens, the product is no longer usable.

Blister packaging, however, prevents this issue entirely. Each capsule is sealed individually, eliminating contact between capsules. Even if one softgel leaks, the rest remain 100% fresh, uncontaminated, and safe to consume.

Cold Damage in Winter

Cold temperatures pose a different risk. When omega-3 softgels are exposed to temperatures below 5 °C (41 °F) for extended periods, the gelatin shell becomes brittle and may develop tiny cracks. These cracks allow oil to escape, leading to oxidation similar to what occurs with heat damage.

Again, blister packaging offers superior protection. It prevents cross-contamination between capsules and preserves the integrity of each individual softgel—even under extreme cold conditions.

Why Choose Premium Blister-Packaged Omega-3 Supplements?

• Maximum protection from heat and cold

• No cross-contamination between capsules

• No rancid smell or taste

• Guaranteed freshness of each individual softgel

• Higher product efficacy and safety

Though premium blister packaging may cost a little more, it ensures your omega-3 supplements remain fresh, potent, and safe, no matter the season.
