Why this formulation Clinically studied rice bran extract and specific daily dose*

Enzymatically modified rice bran and clinical dosing details are cited to support the product's targeted mechanism and use.*

01

Clinically studied compound*

Rice bran exposed to shiitake‑derived enzymes produces immune‑modulating compounds used in this formula.

02

Dose used in studies

Clinical studies evaluated 500 mg daily of the same rice bran compound—matching the product's 1‑tablet serving.*

03

Documented activity changes

A clinical study reported a three‑fold increase in NK cell activity in healthy individuals within three to four weeks at 500 mg daily.

04

Additional immune marker data

A double‑blind, randomized, placebo‑controlled study showed this rice bran also boosted dendritic cell measures.

NK Cell Activator

Supports the activity of natural killer cells*

Helps protect against seasonal immune challenges*

Encourages functional NK cell activity for immune defense

Overview

Our overall immune system can decline over time, especially the activity of NK cells, your body’s first response to unknown immune challenges. NK Cell Activator™ contains 500 mg of a proprietary blend of modified rice bran to strengthen the activity of NK cells with just a few months of use each year.

NK cell activity provides protection against seasonal immune challenges for real-world immune support.*

NK Cell Activator™ Benefits*

  • Supports the activity of natural killer cells*
  • Helps protect against seasonal immune challenges*
  • Encourages functional activity of natural killer cells to support the immune system*

NK Cells: Your First Line of Defense

NK cells normally provide your body’s first, immediate response to previously unknown immune challenges. Because of their nature, encouraging NK cell activity is imperative as we age and is especially important during the winter season.

Product Details

Supports the Activity of Natural Killer Cells
Natural killer (NK) cells function as the body’s first responders. As soon as NK cells sense a potential invasion, they are on the scene to initiate a healthy immune response. NK cells also promote the body’s natural defenses against seasonal immune challenges.*

In addition, NK cells recognize and eliminate senescent cells that accumulate in aged tissues and create metabolic disturbances. NK cell activity declines with normal aging which can affect immune function.

Real-world Immune Support
Studies show that enzymatically modified rice bran significantly boosts NK cell activity. So we created a seasonal immune support formula to provide real-world immune protection from the effects of seasonal immune challenges.*

Clinically Studied Rice Bran Extract
Rice bran exposed to shiitake-derived enzymes produces powerful immune-modulating compounds. In one clinical study, scientists documented a three-fold increase of NK cell activity in healthy individuals within three to four weeks of receiving 500 mg daily of the rice bran compound—the same one used in NK Cell Activator™.*

Another double-blind, randomized, placebo-controlled study showed this rice bran also boosted dendritic cells—important messengers between the innate and adaptive immune systems.
