Koso Cleanse

Koso cleanse was founded on a century-old Japanese cleansing process, which is similar to today's cold-pressed juice cleansing method. This aged practice has proven to strengthen one's mind and body. The main advantage of Koso Cleanse is its richness in prebiotics + probiotics + postbiotics. We are confident you will notice immediate results with your digestive health, while replenishing low microbiome levels.
R's KOSO formula provides a wide variety of nutrients from essential fruits and vegetables, which is vital during any nutrition cleanse. (1 serving: mix 2 tablespoon of R's KOSO with ½ cup of filtered or sparkling water.)

Our 3 Recommend Cleanses:

  • Breakfast Koso Cleanse: Simply replacing your breakfast routine with a single serving of R's KOSO
  • 1-Day Koso Cleanse: Replace all 3 meals with 3-5 servings of R's KOSO each day.
  • 3-Day Koso Cleanse: Replace 3 meals each day for 3 days with 3-5 servings of R's KOSO. * If you want to try 5+ Day Cleanse. Check here.

We recommend starting with our breakfast cleanse method, then gradually increase to our 3-Day Cleanse program as your body adjusts to the nutrition changes.

Breakfast Koso Cleanse

Our Breakfast Koso Cleanse is perfect for beginners or those who just want to add nutrition to their diet.

The unique difference between the Breakfast Koso Cleanse and the 16/8 Intermittent Fasting method is that you include R's KOSO a few hours before the 16 hour fast ends. When completing your fasting with R's Koso, you will gain the perks of increased energy and restored gut microbiome.
