Every parent and caregiver wants to feel confident that their child is getting what they need to grow, learn, and thrive. But with busy routines, changing appetites, and growing bodies, it’s not always easy to ensure all nutritional needs are met. The Junior and Teen Revive range is designed to support children and teenagers during these important years, complementing a balanced diet with nutrients that matter most for growing minds and bodies. In this three-part series, we explore the key foundations of wellbeing during childhood and adolescence and how to support them through food, lifestyle, and a little extra daily backup.

When we think about growth, the gut isn’t always the first place that comes to mind. However, it plays a surprisingly central role in how children absorb nutrients, regulate their immune system, and even support their brain. Far from being just a digestive organ, the gut is home to trillions of bacteria, collectively known as the gut microbiome, that influence everything from  mood to metabolism.

Children and teenagers are especially sensitive to shifts in gut health. The foods they eat, the environments they’re exposed to, and even the amount of sleep they get can all  shape the balance of bacteria  living in their digestive tract. When this ecosystem is in good shape, it helps create the conditions for healthy development. 

Emerging research continues to show how closely the gut and brain are linked. This connection, sometimes called the gut-brain axis, plays a role in how children feel and function, from energy and focus to motivation and emotional regulation.

The gut produces around 90% of the body’s serotonin, a key neurotransmitter involved in mood and behaviour. This means that when the gut is supported with the right nutrients, it can have ripple effects far beyond digestion. A diverse, well-fed microbiome helps modulate these chemical messengers, while also supporting immune balance and reducing the likelihood of gut discomfort, which can be distracting and draining for a growing child.

A food-first approach is always the foundation. Here are some simple, child-friendly ways to nourish gut health:

1. Increase Fibre-Rich Foods

Fibre helps feed good bacteria in the gut and  promotes healthy bowel movements . Include:

• Oats, wholegrains, and brown rice

• Beans, lentils, and chickpeas

• Fruits such as bananas, apples (with skin), and berries

• Vegetables like carrots, sweetcorn, and broccoli

2. Include Fermented Foods

Fermented foods contain beneficial bacteria that may help  replenish the microbiome . These may include:

• Plain yoghurt or kefir (dairy or plant-based)

• Sauerkraut or kimchi (in small amounts for adventurous eaters)

• Miso soup or tempeh for older children and teens

3. Limit Added Sugars and Artificial Sweeteners

Excess sugar can  reduce the diversity of gut bacteria , while some artificial sweeteners may  disrupt gut integrity . Focus on whole foods and natural snacks where possible.

4. Encourage Restful Sleep

The gut follows a circadian rhythm, just like the brain. Supporting regular sleep routines helps  gut motility and microbial balance.

While diet is key, many parents find it reassuring to offer additional support during phases of growth, fussy eating, or digestive sensitivity.

Both Junior Revive and Teen Revive include prebiotics, plant-based fibres that nourish friendly bacteria in the gut. Prebiotics are different from probiotics, which are live bacteria. Instead, they act like  fuel for the good microbes  already present in the digestive tract.

In addition to prebiotics, these formulas include vitamins and minerals that support digestive health indirectly. For example, vitamin C contributes to normal collagen formation, which helps  maintain the structure of the gut lining . Zinc plays a role in  immune health and mucosal integrity . Magnesium supports muscle function, including the smooth muscle of the digestive tract  involved in regular bowel movements.

These nutrients work together to provide a gentle, comprehensive foundation, especially useful during growth spurts, changes in diet, or times when digestive health needs a little extra attention. 

Supporting gut health in children and teens goes far beyond easing digestion. It’s about setting up the body to absorb and use nutrients efficiently, maintain immune resilience, and even support emotional wellbeing. With the right foods, some lifestyle balance, and optional daily support like Junior or Teen Revive, parents can help create an environment where their children’s inner ecosystem has everything it needs to flourish.
