Rice bran is one of the primary byproducts of the rice milling process and contains several nutrients with healthy benefits. When rice bran is enzymatically modified, it can help support natural killer cell activity in the immune system.

Who should take a rice bran supplement?

Anyone who wants to give their immune system some extra support when seasonal challenges are most likely to occur should consider taking a rice bran supplement.

How does rice bran support your immune system during different seasons?

Modified rice bran has immune-modulating properties and promotes the healthy activity of natural killer cells. Since NK cells are the immune system’s first line of defense, they can help protect your immune system in the face of seasonal challenges.

Can you take Life Extension’s NK Cell Activator daily?

Our NK Cell Activator formula is okay to take daily according to the supplement label: Take one (1) tablet one to two times daily with food, or as recommended by a healthcare practitioner.
