Prof. William Dalton, Ph.D.Nutritional yeast offers significant immune support with scientifically proven ingredients. The unique beta-glucan fibers in the yeast activate macrophages and natural killer cells in order to improve the defenses against pathogens. I've seen clients reduce their incidences of cold by about 50% when they take it daily. The zinc content helps provide better numbers and activity of the white blood cells.
Cellular Activation
- Beta-glucan binds to receptors on immune cells triggering response
- Enhances phagocytosis efficiency against pathogens
- Increases cytokine production for coordinated defense
- Amplifies natural killer cell cytotoxicity against infected cells
Antioxidant Protection
- Selenium and glutathione neutralize free radicals
- Protects immune cells from oxidative damage during activity
- Reduces inflammation markers in respiratory tissues
- Preserves immune cell integrity and longevity
Nutrient Support
- Zinc enables thymulin activity for T-cell maturation
- B vitamins support rapid immune cell replication
- Complete proteins provide amino acids for antibody production
- Iron maintains oxygen transport to immune tissues
There are measurable immune benefits, as indicated by clinical evidence. Studies show those who consume them regularly have 25% fewer respiratory infections. The antiviral effects of beta-glucan help eliminate the common virus. I recommend consistent consumption during seasonal times. Take with Vitamin C sources for added protection.
Optimize the timing of your intake for maximum effect. Take nutritional yeast *before breakfast* when the immune cells are at their most active. Add some healthy fats to increase the absorption of the antioxidants in the yeast. Do not cook it at a high temperature because this will destroy the effect of the beta-glucan (one of its constituents). I recommend adding nutritional yeast to soups after they have been cooked, or sprinkling it on salads.
Special formulations help sensitive individuals. Unfortified varieties help autoimmune conditions. Low sodium varieties help hypertension. Children should start with half-teaspoon doses. Always maintain hydration to help circulate immune cells well.
