If You're a Parent, You Need to Read This.
Does your teen experience stomach aches, acne, or low immunity? It might be a result of something that you can't see...
An unbalanced gut microbiome.
The gut microbiome is made up of tiny organisms that help digest food and keep the gut healthy.
When it's out of balance, it can cause digestive troubles and make it hard for the body to absorb nutrients properly.
This can lead to lowered immunity, nutrient deficiencies, acne, and moodiness.
You see, the gut is responsible for several things in our body, to the point that it's even referred to as "the second brain."
So fixing the gut microbiome is essential to improving your teen’s health, but there is a key factor to know about...
Here's what's shocking about it...
Simply eating yogurt, fibrous foods, or supplementing with a probiotic won’t balance your teen's gut or provide what it needs to thrive.
Here's what's shocking about it...
Simply eating yogurt, fibrous foods, or supplementing with a probiotic won’t balance your teen's gut or provide what it needs to thrive.
You see, these sources only provide one phase of the biotic life cycle.
But a balanced gut needs prebiotics, probiotics, and postbiotics.
Not getting all 3 biotics can lead to an unbalanced gut microbiome.
And when parents don't address this imbalance...
It can lead to severe (and sometimes irreversible) consequences. The below discovery is just one of many potential impacts to gut health.
SHOCKING research study FINDS...
Gut microbiota “can affect development of the brain, immune system, lungs, and body growth.”
Here's What You Need To Do About It
To fight the consequences of gut imbalance, you need to give your teens a consistent source of probiotics, prebiotics, and postbiotics.
Every. Single. Day.
And the best way to do that? By supplementing with all 3 biotics.
In fact, scientific studies found that those who supplemented "significantly experienced fewer episodes of diarrhea and increased number of daily bowel movements."[3][4]
But here's the thing: most teen's probiotics do not include all 3 biotics!
For your teens to actually get the gut health benefits, you need pre+, post+, and probiotics with the highest absorption you can get.
Luckily...that supplement finally exists.*

"The boys and mom are both happy!"
I have 2 teenage boys and over the years we have tried and stopped about 5 brands of vitamins…It was either taste, texture, after taste, you had to swallow them, chewable a that are chalky, etc.., Finally found one that has all the good stuff, I don’t have to fight the kids to take, they like and are consistent in taking… so glad we found them and like that we are doing what is best for them when they aren’t making the wisest food choices all the time. The teen vitamins & teen gut gummies are the two we take daily! 😁
