Top Nutrients for Baby's Gut and Brain Health

Your baby’s brain and belly are working overtime in the first few years, growing, learning, absorbing. That’s why early baby nutrition isn’t just about filling their tummy, it’s about fueling development where it matters most.

Here are the essential nutrients that support healthy digestion and brain development, plus simple ways to get them into your baby or toddler’s meals.

Why Gut and Brain Health Go Hand in Hand

Research shows that gut health and brain development are closely connected, even in infancy. A balanced microbiome can support mood regulation, digestion, and even immune function. Meanwhile, early exposure to the right nutrients helps build strong neural pathways and cognitive function.

Supporting both means feeding the body and the brain, intentionally.

Key Nutrients to Prioritize in Early Feeding

1. Choline

Think of choline as brain fuel. It helps build memory and learning pathways and is essential in the first few years of development.

It also supports healthy cell structure and communication between nerves and muscles, playing a vital role as your baby grows, moves, and interacts with the world.

Try it in: eggs, broccoli, or our Mango To Tango and Green Dream pouches.

2. Iron

Iron supports brain development and prevents anemia. Babies are born with some iron stores, but around 6 months, they need more from their diet.

Without enough iron, babies can experience slower cognitive and physical development, so it’s important to incorporate iron rich foods early and often.

Try it in: lentils, spinach, quinoa, and iron-fortified cereals.

3. Omega-3 Fatty Acids (DHA)

While not in our pouches, omega-3s are worth calling out. They’re critical for brain and vision development.

DHA in particular is a building block of the brain and eyes. Including it in your baby’s diet can support focus, learning, and even sleep quality.

Try it in: wild salmon, chia seeds, flax oil, or DHA-enriched foods (consult your pediatrician for supplements if needed).

4. Fiber & Prebiotics

For the gut, fiber is your friend. Prebiotics feed healthy bacteria in the gut and help babies build strong digestion and immune function.

A healthy gut microbiome doesn’t just support digestion, it also plays a role in nutrient absorption, mood regulation, and long-term wellness.

Try it in: pears, bananas, oats, and our Green Dream pouch (made with prebiotics).

5. Antioxidants

These help protect growing cells from damage and inflammation. Blueberries, for example, are packed with antioxidants.

They’re especially important during infancy, when rapid growth and development make cells more vulnerable to oxidative stress.

Try it in: our Berry Cool pouch with organic blueberry and banana.

6. Vitamin C

Helps with iron absorption and boosts immunity.

It’s also essential for collagen production, which supports healthy skin, bones, and blood vessels, key building blocks as babies grow and explore.

Try it in: citrus, mango, strawberries, and lemon juice concentrate (which we use for natural preservation and flavor balance).

When to Start Introducing These Nutrients

• 6 months: Start with purees rich in fiber, Vitamin C, and iron
• 7–9 months: Begin adding prebiotic-rich foods and healthy fats
• 10–12 months: Introduce more textures and a wider range of produce
• Toddler stage (1+ year): Layer in protein, healthy fats, and more plant diversity
