Health Benefits & Sources

Why You Need It

  • Powerful Antioxidant Shield: Fights oxidative stress and cellular damage.
  • Immune System Modulator: Helps balance and strengthen immune responses.
  • Heart Health Support: Promotes healthy blood pressure and circulation.

Deep Dive

The magic of Ligustrum fruit lies in its rich profile of oleuropein and ligstroside. These compounds act like bodyguards for your cells. When your body is under stress—whether from pollution, poor diet, or lack of sleep—free radicals attack your cells. The antioxidants in Ligustrum neutralize these attackers, slowing down aging processes and reducing inflammation. Furthermore, research suggests it stimulates the production of T-cells, the white blood cells that are your first line of defense against invaders.

Natural Food Sources

Unlike Vitamin C found in oranges, Ligustrum is a specific botanical extract. However, you can find similar immune-supporting compounds in these common foods:

  • Who should take it: Those looking to boost immunity during flu season or manage chronic inflammation.
