Here are some of the health benefits that Quit Nutrition can help with, and the research behind these claims.

Supports Immune System

The immune system is strongly influenced by the intake of nutrients. For a long time there has been a controversy whether vitamin C can contribute to the prevention and therapy of the common cold. Several cells of the immune system can indeed accumulate vitamin C and need the vitamin to perform their task, especially phagocytes and t-cells. Thus a vitamin C deficiency results in a reduced resistance against certain pathogens whilst a higher supply enhances several immune system parameters. With regard to the common cold different studies including meta-analyses underline that the prophylactic intake of vitamin C may slightly reduce the duration of the illness in healthy persons but does not affect its incidence and severity. Supplementation of vitamin C is most effective in cases of physical strain or insufficient intake of the vitamin. With regard to the therapy of the common cold the application of vitamin C alone is without clinical effects.

Vitamin C and Immune Function

Increased Antioxidant Activity

Antioxidants are man-made or natural substances that may prevent or delay some types of cell damage. Antioxidants are found in many foods, including fruits and vegetables. They are also available as dietary supplements. Examples of antioxidants include

  • Beta-carotene
  • Lutein
  • Lycopene
  • Selenium
  • Vitamin A
  • Vitamin C
  • Vitamin E

Vegetables and fruits are rich sources of antioxidants. There is good evidence that eating a diet with lots of vegetables and fruits is healthy and lowers risks of certain diseases. But it isn’t clear whether this is because of the antioxidants, something else in the foods, or other factors.

High-dose supplements of antioxidants may be linked to health risks in some cases. For example, high doses of beta-carotene may increase the risk of lung cancer in smokers. High doses of vitamin E may increase risks of prostate cancer and one type of stroke. Antioxidant supplements may also interact with some medicines. To minimize risk, tell you of your health care providers about any antioxidants you use.


Boost Energy & Stamina

Ginseng, eluthero, and maca root are all herbs that have been shown to be adaptogenic herbs, that help boost energy, reduce stress, and increase stamina.  At the core of an adaptogen’s scope of actions is the ability to help the body cope more effectively with stress. Specifically, adaptogens recharge the adrenal glands, which are the body’s nominal mechanism for responding to stress and emotional changes.

Ginseng Health Benefits

B vitamins are an essential group of vitamins that helps with energy production. Referred to as vitamin B complex, the eight B vitamins — B1, B2, B3, B5, B6, B7, B9, B12 — play an important role in keeping our bodies running like well-oiled machines. These essential nutrients help convert our food into fuel, allowing us to stay energized throughout the day.

B Vitamins

Promote Lung Health

Vitamins A, B-6, C, D, and E, and Selenium are all essential for lung health.  Having low blood levels of vitamin D may be associated with an increased risk for respiratory infections, cystic fibrosis, chronic obstructive pulmonary disease and interstitial lung disease. Vitamin B-6 may help keep your DNA from becoming damaged and mutating, thus lowering your risk for lung cancer. Vitamin A, or its precursor, beta-carotene, to maintain your lungs and keep them functioning normally. Vitamin E has been show to lower COPD risk.

Supplemental Selenium and Vitamin E and Pulmonary Function

N-acetylcysteine is an amino acid that has been show to play a key role in lung health.  Oxidative stress has been implicated in the pathogenesis and progression of COPD. Both reactive oxidant species from inhaled cigarette smoke and those endogenously formed by inflammatory cells constitute an increased intrapulmonary oxidant burden. Structural changes to essential components of the lung are caused by oxidative stress, contributing to irreversible damage of both parenchyma and airway walls. The antioxidant N-acetylcysteine (NAC), a glutathione precursor, has been applied in these patients to reduce symptoms, exacerbations, and the accelerated lung function decline. This article reviews the available experimental and clinical data on the antioxidative effects of NAC in COPD, with emphasis on the role of exhaled biomarkers.
