HERE'S WHAT MOST PEOPLE DON'T KNOW...

3 Revealing Facts About Gut Health

ALL Disease

Begins In The Gut

Many mystery symptoms are actually GI issues in "disguise"

Your gut isn't just for digestion – it has a multitude of important functions important for mood & neurotransmitter production, as well as your immune system. For example, your gut is your primary immune response as pathogens enter the body through your nose & mouth. So even if you don't have any obvious signs of GI issues, know that your gut affects everything.

Your Microbiome

Rules The Body

Have diet or antibiotics wrecked your microbiome?

Sometimes, the gut isn’t actually the problem, it's what you eat and how that affects the billions of bacteria in your GI tract. A poor diet (or frequent use of antibiotics) can kill the good gut bacteria – allowing harmful bacteria to flourish. This prevents the body from producing critical vitamins and neurotransmitters essential for balanced mood, all-day-energy and a resilient immune system!

Leaky Gut & Inflammation

Is your immune

system on fire?

Persistent gut issues (leaky gut) can spiral into systemic inflammation... causing your immune system to be on "high alert". An over-vigilant immune system can result in a wide range of symptoms from joint pain to skin issues and more. It's no wonder that gut issues can cause "seemingly unrelated" symptoms... so we need to address gut dysbiosis and clean up chronic inflammation to address multiple symptoms at once.
