Vitamin E refers to a group of fat-soluble compounds (tocopherols and tocotrienols). In the context of omega-3 supplements, it frequently serves a vital dual purpose: it acts as a cellular antioxidant within the human body, and it prevents the highly fragile polyunsaturated fats (EPA/DHA) from oxidizing (going rancid) inside the capsule before ingestion.

Clinical Summary

Validated as a potent cellular antioxidant. Its role in preventing lipid oxidation (both in human cellular membranes and in supplement formulations) is universally recognized by lipid scientists.

Dosage Guidelines

15mg (22.4 IU) daily for baseline health; often used in trace amounts in fish oil strictly as a preservative.

Safety & Side Effects

Generally safe at normal doses. Megadoses (over 1,000 IU) can increase bleeding risk.

Known Interactions

Can interact with blood thinners and cholesterol-lowering medications.
