Some supplements have been subject to recalls due to potentially elevated levels of certain vitamins or environmental contaminants. It is important to choose products from reputable manufacturers to minimize the risk of consuming adulterated or oxidized oils.

Allergies and General Side Effects

People with a known allergy to fish or shellfish should use caution when considering this supplement. Common side effects often include a fishy aftertaste, bad breath, heartburn, nausea, or loose stools.

Regulatory Classification

This compound is categorized as a dietary supplement rather than a drug. Under this classification, the ingredient is not required to be proven safe or effective to the satisfaction of federal regulators before it is marketed to the public. Instead, the responsibility for ensuring product safety and truthful labeling rests primarily with the manufacturers.

Marketing and Labeling Restrictions

Federal regulations prohibit manufacturers from claiming that it can diagnose, treat, cure, or prevent any disease. When a product is marketed with therapeutic claims—such as suggesting it can treat chronic conditions—it is legally classified as an unapproved new drug. Regulatory agencies monitor these claims and may issue formal warning letters to companies that violate these standards by making unsubstantiated medical assertions.

Safety Oversight and Enforcement

While pre-market approval is not required, the government maintains post-market oversight to protect public health. This regulatory framework includes:

• Manufacturing Standards: Facilities must follow Good Manufacturing Practices to ensure products are processed consistently and meet quality standards.
• Product Recalls: Authorities may initiate or oversee recalls if a supplement is found to be contaminated, contains unsafe levels of certain nutrients, or poses other health risks.
