How To Strengthen Immunity

how to strengthen immunity

A strong and balanced immune system consists of a healthy diet along with a proper lifestyle. But even with these habits, you may still need to reinforce your resistance. Strengthen your immunity with these supplements.

Vitamin C

Vitamin C or Ascorbic Acid is a versatile antioxidant that protects cells from free-radical damage as well as supports your immune system. Even though Vitamin C can be found in a wide array of fruits and vegetables, you may need more for optimal resistance. NOW® AlphaSorb-C uses threonic acid, a vitamin C metabolite that supports cellular uptake, and alpha-lipoic acid to help regenerate and enhance the utilization of vitamin C in the body. NOW® C-1000 Antioxidant Protection includes bioflavonoids, a polyphenolic compound which works synergistically to support vitamin C utilization.

Vitamin D

Vitamin D is a fat-soluble vitamin that is important in maintaining a healthy immune system. The body produces vitamin D naturally when the skin is exposed to the sun, but during days when there is not enough sunlight or when you are stuck indoors, you may need to take a supplement. NOW® Vitamin D-3 2000IU Softgels High-Potency Softgels is a highly-absorbable vitamin D supplement that can support immune health.

NOW® Vitamin D-2 Veg Capsules is a vegan substitute that contains ergocalciferol, a form of vitamin D that is derived from plant sources.

Indole-3-Carbinol (I3C) is a sulfur-containing compound that is converted to diindolylmethane (DIM) when in the body. This compound is used to protect against free radicals and helps promote a healthy immune response. This compound is naturally found in cruciferous vegetables like cabbage, cauliflower, and broccoli.

NOW® Indole-3-Carbinol is crafted with immune-enhancing phytoestrogens to help gain a stronger immune system.


Probiotics are well known to support a healthy immune system and are beneficial bacteria that are found in the digestive system and the mouth. S. salivarius is the most beneficial bacteria in the mouth, with BLIS K12® standing out as being the most powerful strand of S. salivarius. BLIS K12® helps colonize the mouth, throat, and gut to help defend the oral cavity.

NOW® OralBiotic® Lozenges combine BLIS K12® with Fructooligosaccharides (FOS) to help nourish beneficial bacteria.


Beta-Glucans are biologically active compounds that help enhance immune cells to provide a healthy immune response. Beta-1,3/1,6-D-Glucans are found in Saccharomyces cerevisiae (Baker’s Yeast) and have been found to maintain and strengthen the body’s normal immune functions.

NOW® Colostrum Veg Capsules and NOW® Super Colostrum is a unique blend of colostrum, ImmunEnhancer™, olive leaf, and astragalus to help maximise immune defenses.


Zinc is an essential mineral when it comes to the production of immune cells and strengthening the immune system. Zinc can be found in a variety of foods like oysters, red meat, and poultry, but vegans and vegetarians may have trouble getting enough zinc in their diet. Because of this, a zinc supplement is needed.

NOW® Zinc Glycinate helps improve the absorption and bioavailability of zinc.

NOW® AlliBiotic CF™ is a combination of potent garlic extracts with other immune boosting components for additional reinforcements.

NOW® Odorless Garlic is an odorless garlic extract that has been purified and deodorized to all while maintaining the nutritional value of garlic.

Mushrooms and Astragalus

Medicinal mushrooms such as reishi, turkey tail, maitake, and lion’s mane have long been revered and studied for their health-promoting properties; they’re high in beta-glucans and other substances that have been demonstrated to boost a healthy immune response.

Astragalus, an adaptogenic plant utilized in traditional Chinese herbalism for generations, also helps strengthen immunity.
