Celebrate National Smile Day from the Inside Out - Tips to Support a Happy Gut and a Happier You

– Celebrate National Smile Day from the Inside Out –

Have you ever noticed how your mood shifts when your digestion feels off? Or how you feel lighter - both physically and mentally - after eating nourishing foods? It’s not just a coincidence. There's a growing body of science that shows how closely the gut and the brain are connected.

As we celebrate National Smile Day on May 31, it's the perfect time to explore how taking care of your gut can naturally support a more balanced, joyful mood.


The Gut-Brain Connection: More Than a Feeling

Your gut is often called your "second brain". That is because the gut contains millions of neurons and is directly connected to the brain through the gut-brain axis, a two-way communication system.

What does that mean for your mood?

Your gut produces over 90% of the body’s serotonin, a key neurotransmitter that regulates mood, sleep, and even appetite. A well-balanced gut microbiome plays a huge role in keeping these feel-good chemicals in check.


When the Gut is Imbalanced...

An imbalanced gut (due to stress, poor diet, lack of rest) can contribute to:

  • Mood swings

  • Anxiety or low mood

  • Brain fog or poor concentration

  • Increased sensitivity to stress

  • Weight gain

That’s why nurturing your gut daily is not just about digestion. It is about emotional resilience as well. 


How R’s KOSO Supports Emotional Well-Being

R’s KOSO is a fermented postbiotic drink made from more than 100 kinds of wholefoods such as fruits, vegetables, mushrooms, seaweeds, Japanese herbs, and even seasonal foods. It's rich in:

  • Prebiotics, probiotics, postbiotics, and polyphenols to support a diverse microbiome

  • Postbiotics and polyphenols, which help reduce inflammation and support gut-brain signaling

You could have a tablespoon of R's KOSO original (or 2 teaspoons of R's KOSO lower sugar) with a cup of water every day to support your gut health consistently. You could also do a 1 to 5-day cleanse using R's KOSO to rest, nourish, and balance your gut at the same time. R’s KOSO may help create a more balanced foundation for emotional wellness.


Tips to Support a Happy Gut - and a Happier You

  • Start your morning with 1 tablespoon of R’s KOSO in a cup of water to gently activate digestion and feed your microbiome

  • Eat more fiber-rich plant foods to nourish your gut bacteria

  • Practice mindful eating - how you eat affects how you feel

  • Stay hydrated to support detox and digestion

  • Get enough sleep, as rest and digestion go hand-in-hand

Smile From the Inside Out

True emotional wellness starts in the gut. So this National Smile Day, let’s celebrate by nurturing our inner ecosystem because when your gut feels good, your mind follows.

Take care of your gut, and the smiles will follow naturally.
