Why is vitamin E included in an omega fatty acid supplement?

Vitamin E is included primarily as a protective antioxidant. Omega-3 and omega-6 fatty acids, particularly the polyunsaturated ones found in fish, flaxseed, and sunflower oils, are chemically sensitive and can degrade when exposed to oxygen—a process called oxidation.

By adding vitamin E to the formula, it helps protect these delicate oils from oxidative stress both in the capsule during storage and potentially within the body after consumption. This complements formulas based on polyunsaturated fats by helping to maintain their integrity.

This is a common and practical formulation choice for oil-based supplements, ensuring you receive the fatty acids in a supported, stable state. It underscores that the product is designed for regular, long-term use as part of a daily routine.
