Maximum Immune Support


  • Reduce Incidence of Colds*
  • Antibacterial, Antiviral, and Antioxidant*
  • Boost Immune Cell Count*
  • 2,000IU Vitamin D3
  • 30 Servings




Having a strong immune system is vital to good health and longevity. Supplementing for optimal immune function often leads people to a vitamin C supplement, but there are many other ways to improve immune health. In large part, immunity is improved by enhancing the health and number of white blood cells, resisting germs, and reducing oxidation to help offset feelings of unwellness.*


  • Vitamin C increases antioxidant enzyme activity, aids the immune system, and reduces harmful effects of stress.*
  • Astragalus activates the immune system by assisting white blood cells (B cells and T cells).*
  • Elderberry supplementation helps alleviate unwanted sensations.*
  • Olive extracts containing polyphenols which have shown efficacy for promoting favorable germ cell profiles.*
  • Echinacea increases macrophage ability to enhance adaptive immunity.*


Immunity+ focuses on providing fuel for the workers of the immune system – the antioxidants, macrophages, immunoglobulins, and other great fighting, health-boosting cells. Get back in the game, with Immunity+.

Supplement Facts

Best Cold Prevention

Ingredient Profile

Vitamin C

The immunity vitamin. Vitamin C helps improve antioxidant status, and it has shown efficacy for reducing the duration and intensity of cold symptoms.

  • A vitamin C supplement can help reduce oxidative stress throughout the body.
  • In athletes, vitamin c supplementation has been observed to reduce upper respiratory tract infection duration, frequency, and severity.
  • Vitamin C supplementation can help mitigate the negative health effects of stress.


Vitamin D

Vitamin D is best known for improving bone health, and it has many other functions. Some of those functions include improving immune health.

  • Vitamin D helps improve macrophage (cells which “eat” pathogens, protecting the body) function by reducing their adhesion to the cell wall.
  • Increasing body vitamin D levels has been noted to reduce symptoms of autoimmune dysfunction.
  • Increases regulatory T cell and memory B cell counts.



Zinc is an essential mineral with many roles. It is one of the most important minerals for immune health.

  • Zinc is used to form superoxide dismutase, an antioxidant enzyme.
  • Zinc deficiencies are associated with immune dysfunction, among other complications.
  • Supplementing zinc at the onset of a cold and during other viral infections has been observed to reduce duration and severity of symptoms.


Astragalus Root

Astragalus is an herb used in traditional Chinese medicine. It is purported to have life extension effects.

  • Astragalus activates T cells to a greater extent than echinacea, which is independently capable of improving immune function.
  • Astragalus supplementation encourages proliferation of immune cells, immunoglobulins, and macrophages.
  • Collectively, this suggests enhanced adaptive immunity – a more specific and responsive type of immunity.



Elderberry is also known as Sambucus. There are several varieties of elderberry, but the most effective as a supplement is Sambucus nigra.

  • Elderberry is rich in nutrients such as vitamin C, fiber, polyphenols, and anthocyanins.
  • Supplementing with Elderberry relieves symptoms of influenza an average of 4 days faster than placebo.
  • Extracts of Elderberry also help fight bacteria, such as H. pylori.


Olive Leaf Extract

Olives, and other parts of the plant contain several beneficial properties.

  • Components of olive leaf extract possess antiviral effects
  • Olive leaf may also be antibacterial against Staph infections



Lysine is an essential amino acid. It has shown promise in combatting certain types of infections.

  • Lysine promotes absorption of certain minerals, such as calcium
  • As an arginine competitor, lysine may be effective at reducing the severity of herpes flare ups (Griffith, 1987).



Echinacea is often used at the first sign of sickness to help accelerate recovery and occasionally as a prophylaxis against colds.

  • Echinacea may stimulate macrophage production, helping fight pathogens.
  • A larger body of evidence suggest echinacea is effective for reducing the duration of sickness.


Grape Seed Extract

Grape seed has recently been discovered as a significant source of polyphenols and other antioxidants.

  • It has shown great promise for improving overall health, particularly cardiovascular health.
  • Using grape seed extract may be able to suppress inflammatory reactions to antigens, easing allergic symptoms.

Q: What is the best way to use Immunity+?

A: As a dietary supplement, take 1 serving (1 capsule) daily to a stronger immune system.


Q: Does Immunity+ need to be taken with food?

A: For best absorption, use Immunity+ with food.


Q: Are there any Optitune products that can be stacked with Immunity+?

A: Yes! For the best improvements in immune function, use Immunity+ with Fruits and Greens.
