Good Guts Gone Bad
Unmasking a hidden health crisis plaguing kids with tummy aches, bad breath, and weak immunity.
Did you know that your gut is connected to every organ in the body? It even makes up 70% of the immune system! Which is why an imbalanced gut – where there’s more bad bacteria than good – can wreak havoc on digestion, immunity, and even oral health.
And unfortunately, turning to quick fixes like eating yogurt, bland foods, or even taking probiotics, won’t solve the problem.
What's Wrong With Probiotics
The Shocking Reason Why This Popular Supplement Won’t Solve Your Kid’s Gut Issues
Ever given your child probiotics but felt like they didn’t make a difference? The reason is simple. Probiotics, whether in food or in supplements, only provide one phase of the biotic life cycle.
But a balanced tummy needs all 3: Prebiotics, Probiotics & Postbiotics.
And because an imbalanced gut affects every organ in the body, research finds that gut microbiota can affect development of the brain, immune system, lungs, and body growth.1
