Life Extension's NK Cell Activator is an immune support supplement available in a bottle with 30 veggie tabs. The primary ingredient is a modified rice bran, known as enzymatically modified rice bran or AHCC (Active Hexose Correlated Compound), clinically proven to aid in the functioning of natural killer (NK) cells.

By way of background, NK cells are critical components of the immune system which are known to respond to and eliminate abnormal cells in the body. Regular intake of NK Cell Activator supports enhanced NK cell activity, leading to a better-functioning immune system.

Each veggie tab contains 500 mg of the modified rice bran. The recommended dosage is one (1) tablet 1 to 2 times daily with or without food, or as advised by a healthcare practitioner. It is generally taken for four months as part of a regimen to boost NK cell activity.

Life Extension NK Cell Activator is non-GMO. It's also free from gluten, so it fits in with a wide variety of dietary requirements. The product is made with vegetarian-friendly ingredients and the veggie tabs are suitable for vegans.

As with all supplements, it's important to remember that they should not replace a balanced diet. Like all Life Extension products, NK Cell Activator is a supplement designed to target a specific area of your health—in this case, your immune system. It should be stored in a cool, dry place and out of reach of children.
