Children's growth doesn't happen in neat, predictable steps, it's a whirlwind of new words, new movements, and new discoveries. Behind every milestone is a growing brain, an evolving body, and countless tiny building blocks coming together.
One of those critical building blocks is DHA, an omega-3 fatty acid that quietly supports everything from sharper vision to stronger memory and faster learning. It's a nutrient many parents have heard of, but few know exactly how much their child needs, or how to reliably get enough.
In this guide, we'll cut through the noise. You'll find a simple breakdown of how much DHA children need at different ages, why it matters so much during early development, and practical ways to help them get it, whether through diet, supplementation, or both.
DHA and Childhood Growth: A Natural Building Block
A child's body is built day by day, through the nutrients that quietly fuel each stage of development. Docosahexaenoic acid (DHA), a type of omega-3 fatty acid, is one of those essential materials.
DHA is naturally found in fatty fish, like salmon and sardines, fortified foods, and some plant-based sources like algae. A balanced, whole-foods diet rich in these nutrients is one of the best ways to support your child's brain, eyes, and nervous system during their rapid growth years.
Still, for many families, everyday challenges make it harder to consistently meet these needs through food alone. Busy schedules, picky appetites, dietary restrictions, or simple access to fresh foods can create gaps, and that's where thoughtful supplementation becomes a practical, supportive tool, not a replacement for healthy eating.
It's important to know that needing a supplement doesn't mean you're falling short as a parent. It's simply one more way to help your child thrive when life gets complicated.
Why DHA Matters: Evidence from Research
Scientists have studied DHA's role in childhood development for decades. Here's what current research suggests:
-
-
Brain Development: DHA accumulates rapidly in a child's brain during the last trimester of pregnancy and the first two years of life. Studies, such as those reviewed in the American Journal of Clinical Nutrition (Innis, 2007), have linked DHA levels to cognitive functions like attention, memory, and problem-solving.
-
Vision Health: DHA is highly concentrated in the retina. Research published in Investigative Ophthalmology; Visual Science (SanGiovanni et al., 2000) has shown that sufficient DHA intake is associated with normal visual development in infants and children.
-
Nervous System Function: DHA supports the formation of neural membranes and communication between nerve cells. Evidence from multiple studies, including those summarized by the National Institutes of Health, suggests that DHA may help maintain healthy mood regulation and motor skills in growing children.

How Much DHA Do Children Need Daily?
When it comes to nutrients like DHA, many health organizations offer recommended daily intakes, but what do these numbers really mean?
Recommended intakes are based on research into typical dietary patterns, blood levels of nutrients, and developmental outcomes. Scientists study how much DHA children tend to have in their diets, how that relates to growth, and what intake levels seem to support optimal brain, vision, and nervous system development over time.
These guidelines aren't designed to be a strict pass/fail test. They're tools, helpful benchmarks that can guide parents in supporting their child's health without adding unnecessary stress.
Here's a simple overview of commonly cited DHA intake ranges for children:
These ranges come from sources like the National Institutes of Health (NIH) and the European Food Safety Authority (EFSA), which review large bodies of nutritional science to shape practical, reasonable recommendations for growing children.
It's important to remember that one meal, or even one day, doesn't define a child's nutrition. What matters most is the overall pattern over time, and small, consistent steps toward providing enough DHA can make a real difference in supporting long-term health.
Meeting DHA Needs: Why Supplements Can Play a Supportive Role
The richest natural sources of DHA are well-known: fatty fish, like salmon, sardines, and mackerel; some fortified foods such as certain dairy products and eggs; and plant-based options like algal oil for those following vegetarian diets.
For many families, building a DHA-rich diet is absolutely possible, and we celebrate that. Creative meals, smart planning, and a focus on whole foods can go a long way in supporting a child's growth.
Still, life is rarely simple or predictable. Even with the best intentions, some common realities can make consistent DHA intake a little more complicated:
-
-
Dietary Choices and Restrictions: Families following vegetarian, vegan, allergen-sensitive, or religious dietary practices may naturally have fewer food-based DHA options.
-
Access and Availability: Fresh, DHA-rich foods like sardines aren't always affordable or readily available everywhere, especially for busy families juggling multiple priorities.
-
Consistency Over Time: Nutritional gaps don't usually appear overnight, but over weeks and months, minor shortages can add up. It's not about a single meal, but the patterns we build day after day.
-
Modern Lifestyles: Even the most mindful households sometimes face schedules, stressors, and seasons of life where home-cooked, nutrient-packed meals aren't always possible.
-
Choosing to support your child's nutrition with a supplement isn't a sign of falling short, it's a thoughtful way of adapting to real-world challenges with care and intention.
If you're exploring DHA supplements for your child, it's not because you haven't tried hard enough, it's because building a strong nutritional foundation sometimes means thoughtfully adding extra support.
When we began working on CATALO Children's DHA, it was to build something we would feel comfortable and proud giving to our own children, with ingredients we could stand behind, choices we could explain honestly, and research to back the benefits.
We believe that parents deserve products that reflect the same care, caution, and high standards they bring to their families every day.
What to Look for in a DHA Supplement
If you're choosing a DHA supplement, whether it's ours or another, there are a few things we believe truly matter:
-
Clean, Transparent Sourcing
Fish oil should come from purified sources tested for heavy metals, PCBs, and other contaminants. Look for clear sourcing information, not vague language. -
Child-Appropriate Formulation
Children's needs differ from adults'. A supplement for kids should prioritize DHA over EPA, supporting brain, vision, and nervous system development during key growth years. -
Thoughtful Extras
Some formulas include additional supportive ingredients, but these choices should be intentional, backed by research, and made clear to the parent.
Our Choices, and Why They Matter
Here's how we approached CATALO Children's DHA with these standards in mind:
-
Source: Our DHA comes from purified fish oil, primarily from anchovy, sardine, and mackerel, smaller fish less prone to mercury accumulation.
-
Purity: Our oils are rigorously tested for quality and safety at multiple stages of production.
-
Form: We chose chewable softgels with natural flavors to make daily consistency easier for kids and parents alike.
-
Fillers and Additives: We keep our ingredient list simple. Our softgels are made with food-grade gelatin and glycerin, common, food-safe ingredients used to hold the softgel shape, and natural flavoring for palatability. No artificial colors, unnecessary preservatives, or questionable additives.
A Tool, Not a Shortcut
CATALO's Children's DHA isn't designed to replace healthy eating. It's simply here to offer extra support, a tool that fits into the bigger, richer picture of helping children grow strong, vibrant, and resilient.
We are proud to be part of the broader conversation about helping children thrive.
Your standards are high, and they should be. We're here to meet them with CAre, viTALity, and LOngevity.
