The Claim

Omega-3 supplements in softgel form without flavor additives exhibit significantly lower secondary oxidation and total oxidation levels compared to bulk oils and flavored softgels.

In plain English

Omega-3 supplements in unflavored softgel capsules have less chemical breakdown from oxidation than bulk oils or flavored softgels.

See the scientific wording

Omega-3 supplements in softgel form without flavor additives had significantly lower secondary oxidation and total oxidation levels than bulk oils or flavored softgels, suggesting encapsulation without additives may improve oxidative stability.

Why this might work

The omega-3 oil is sealed in a softgel shell without added flavors, which prevents contact with chemicals that speed up spoilage and stops air and light from reaching the oil, so it stays fresh longer.

  1. Study: Oxidation levels of North American over-the-counter n-3 (omega-3) supplements and the influence of supplement formulation and delivery form on evaluating oxidative safety

    Scientists tested different omega-3 supplements and found that plain, unflavored capsules had less spoiled oil than liquid versions or flavored ones. This means keeping the capsules simple helps the omega-3s stay fresh longer.
