Omega-3 fatty acids are a crucial component of a healthy diet.

These essential fats are especially important for children, as they play a key role in growth and development and are associated with numerous health benefits.

However, many parents are unsure whether omega-3 supplements are necessary — or even safe — for their children.

This article takes an in-depth look at the benefits, side effects, and dosage recommendations of omega-3 supplements to determine whether kids should take them.

What are omega-3s?

Omega-3s are fatty acids that are integral to many aspects of health, including fetal development, brain function, heart health, and immunity.

They’re considered essential fatty acids because your body cannot produce them on its own and needs to obtain them from food.

The three main types are alpha-linolenic acid (ALA), eicosapentaenoic acid (EPA), and docosahexaenoic acid (DHA).

ALA is present in a variety of plant foods, including vegetable oils, nuts, seeds, and certain vegetables. Yet, it isn’t active in your body, and your body only converts it into active forms, such as DHA and EPA, in very small amounts.

Meanwhile, EPA and DHA occur naturally in fatty fish, such as salmon, mackerel, and tuna, and are widely available in supplements.

While many types of omega-3 supplements exist, some of the most common are fish oil, krill oil, and algae oil.
