Indoles are nutrients naturally found in a variety of vegetables and fruits. If users do not enjoy a diet high in vegetables and fruits, they may also purchase indoles in supplements.

Studies show that indoles are highly nutritious and capable of providing the body with disease-fighting benefits. A diet high in indoles helps prevent the growth and spread of different types of disorders in the gastrointestinal system, such as ulcers.

Indoles can also help provide the body with general immune system benefits. Indoles help optimize the way the immune system functions, resulting in stronger defenses in the host body and long-term benefits in keeping various diseases at bay.

Research also shows that indoles can provide users with general inflammation benefits. Regularly introducing the nutrients into the body can help make the pain response more manageable in those who suffer from some type of chronic condition, especially one resulting from an illness.
