If you read our Prebiotics: What, Why, Where?  post last week, you’ll know that probiotics are live “good” bacteria, and usually the ones that live in our gut.

(And if you didn’t read it… well, now you know too.)

Having a healthy balance of these bacteria — known as the gut microbiome — plays an important role in our overall health. It can support digestion, immune function, and even mental wellbeing via the gut–brain axis.

So probiotics sound quite important. Should I give my child a supplement?

For most healthy children, probiotic supplements are not necessary and can be quite expensive.

Our bodies are generally very good at maintaining a healthy balance of good and bad bacteria on their own, especially when supported with a varied, balanced diet.

However, there are some situations where a probiotic supplement may be worth considering:

• After antibiotics
  Antibiotics kill bacteria (that’s their job), but they don’t discriminate — meaning both good and bad bacteria can be affected. Probiotics can help support recovery afterwards.
• For some digestive issues
  In certain cases, probiotics may be recommended to support gut health.
• When advised by a healthcare professional

Before reaching for a supplement, it’s always a good idea to try a food-first approach. Luckily, some foods naturally contain beneficial bacteria, including:

• Greek or unsweetened yoghurt with live cultures
• Kefir
• Fermented foods like tempeh 

Including prebiotic foods regularly can also help the good bacteria you already have to thrive. Some good prebiotic foods include:

• Bananas (especially slightly green ones)
• Oats
• Garlic and onion
• Apples
• Asparagus
• Artichoke
• Wholegrains 

If you do choose a probiotic supplement:

1. Look for reputable brands with specific strains listed
2. Be cautious of very cheap options (unfortunately you can often get what you pay for)
3. Speak with a GP, dietitian, or maternal child health nurse if considering long-term use
