It has been possible to verify by in vitro controls that these berries possess polysaccharides with a high antioxidant action.

The most studied active principle is LBP and it has been discovered that it has different pharmacological actions on the body:

  • Improves general health
  • Acts on the immune response
  • Has antitumor activity
  • Increases insulin secretion

The increase in antioxidants in the body produced by the consumption of goji berries could help prevent or reduce the damage caused by free radicals , according to this clinical study (4). Free radicals can cause, for example: premature aging, cataracts, atherosclerosis, cancer, diabetes or DNA mutations. Antioxidants are capable of neutralizing the damage of free radicals and that is why it is so important to incorporate them into the daily diet through food.

In a review on the anticancer action of goji berries (5), their main active components (LBP, scopoletin and AA-2βG) are pointed out as those responsible for the inhibitory effect on the proliferation of cancer cells. LBP was even found to help regulate the immune system and enhance the effects of other anticancer therapies.
