  • Polyphenols, or phenolic compounds: these usually have a potent antibiotic and anti-inflammatory effect.
  • Carbohydrates and proteins: these are important sources of energy.

  • Other phytonutrients, such as vitamins B1, B2, B3, B5, B6, B12, C, E and folic acid: they can reduce free radicals and regulate the body's metabolism.

Can noni treat cancer?

In popular culture, noni has been purported to potentially treat various diseases, such as cancer, depression, allergies and diabetes. However, safe consumption has not been scientifically supported and excess intake can put your health at risk. For this reason, the consumption of noni is not recommended until there is concrete evidence of its safety and efficacy, with tests carried out on humans.
