Omega-3 PUFAs (Polyunsaturated Fatty Acids) are essential fatty acids that play an important role in human nutrition. Since the body cannot produce sufficient amounts on its own, they must be obtained through food or supplements. The most common types of omega-3 fatty acids are EPA (eicosapentaenoic acid), DHA (docosahexaenoic acid), and ALA (alpha-linolenic acid).

Omega-3 PUFAs are naturally found in foods such as fatty fish, algae, flaxseeds, chia seeds, walnuts, and certain vegetable oils. They are also widely available in dietary supplement forms, including fish oil, krill oil, and algae-based products. Their versatility has made them a common ingredient in functional foods, beverages, and nutritional products.

Growing awareness of nutrition and wellness has increased interest in omega-3-rich foods and supplements. As a result, omega-3 PUFAs continue to be widely used across the food, dietary supplement, pharmaceutical, and animal nutrition industries, making them an important component of modern nutrition and product development.
