Features

  • LEAKY GUT REPAIR SUPPLEMENT POWDER - GutAssist supports the healing of the body’s protective membranes along the GI tract, giving these membranes nutrients like L-Glutamine to thrive and heal.
  • IMMUNE SYSTEM SUPPORT - Good health really does start in the gut. Poor gut health can even lead to a bad mood, depression, and other imbalances that effect the quality of our lives. Maintaining good gut flora and balance is essential for proper digestive health and gut integrity. Inside your body, the gut wall houses many cells that comprise your immune system.
  • GI TRACT + DIGESTIVE SUPPORT - A healthy gut lining supports nutrient delivery, and a well-balanced digestive tract is essential to achieving good nutrient delivery. An imbalanced gut can lead to complications like bloating, IBS, constipation, diarrhea, cramps, or gas. A poorly functioning gut can also disrupt the balance and harmony of our body, sometimes leading to a bad mood, depression, anxiety, or stress.
  • GLUTAMINE, ALOE VERA, LICORICE ROOT, ARABINOGALACTAN - L-Glutamine is the body’s most plentiful free-form amino acid, and is central in sustaining gastrointestinal function. Glutamine is a significant carrier of nitrogen within the body, which is essential in the cellular healing.
  • CAN BE TAKEN WITH PROBIOTICS, DIGESTIVE ENZYMES, PREBIOTICS - When leaky gut occurs a person may experience an almost allergic-level response to these offending food particles or bacteria that have leaked through the gut wall into the bloodstream. The result can be uncomfortable gastrointestinal symptoms such as cramps, gas, extreme food sensitivity, bloating, abnormal bowel movements, and inflammation. A leaky gut can also manifest itself in other ways.
