Increase “acetic acid” and “butyric acid” with kestose

It reaches the large intestine and becomes a source of nutrients for bifidobacteria, lactic acid bacteria, and butyrate-producing bacteria, allowing butyrate-producing bacteria to proliferate in large numbers.

Butyric acid has immunomodulatory and metabolic improvement functions, and has been reported to have immune-stimulating effects, including improving atopic dermatitis in infants, and to prevent and improve lifestyle-related diseases through improving insulin resistance.

Problems faced by many people

  • atopic dermatitis

    Kestose, a highly safe carbohydrate, can be safely consumed by infants and young children.
    Effects were seen within 6 to 12 weeks of infants and children with atopic dermatitis taking Kestose.

  • Hay Fever

    Hay fever occurs when the body overreacts to pollen due to a malfunction of the immune system that tries to protect the body. By adjusting the intestinal environment, the immune system functions normally and suppresses the symptoms of hay fever.

  • skin trouble

    When the intestinal environment deteriorates, the balance between bad and good bacteria is disrupted. When digestion is impaired, substances that are supposed to be digested and putrefied in the intestines turn into toxins and reach the skin.
    By adjusting the intestinal environment, skin problems will improve.
