Zinc’s intestinal uptake is hindered by other minerals, including Calcium, Magnesium, and Iron, since they all use the same transporter. If the transporter’s uptake limit (800mg) is exceeding between these four minerals, absorption rates will fall. Taking less than 800mg of these four minerals at the same time is fine."

Zinc and the immune system - 2000

Zn is an essential trace element for all organisms. In human subjects body growth and development is strictly dependent on Zn. The nervous, reproductive and immune systems are particularly influenced by Zn deficiency, as well as by increased levels of Zn. The relationship between Zn and the immune system is complex, since there are four different types of influence associated with Zn.

  • (1) The dietary intake and the resorption of Zn depends on the composition of the diet and also on age and disease status.
  • (2) Zn is a cofactor in more than 300 enzymes influencing various organ functions having a secondary effect on the immune system.
  • (3) Direct effects of Zn on the production, maturation and function of leucocytes.
  • (4) Zn influences the function of immunostimulants used in the experimental systems.

Here we summarize all four types of influence on the immune function. Nutritional aspects of Zn, the physiology of Zn, the influence of Zn on enzymes and cellular functions, direct effects of Zn on leucocytes at the cellular and molecular level, Zn-altered function of immunostimulants and the therapeutic use of Zn will be discussed in detail.

  • "In a randomized, double-blind, placebo-controlled clinical trial, 50 subjects (within 24 hours of developing the common cold) took a zinc acetate lozenge (13.3 mg zinc) or placebo every 2–3 wakeful hours. Compared with placebo, the zinc lozenges significantly reduced the duration of cold symptoms (cough, nasal discharge, and muscle aches) [67]."

8 major uses of Zinc in the body

Science Daily reporting on a 2014 study

  • Brain: The blood zinc level is less in patients with Alzheimer's and Parkinson's disease (Brewer, and others 2010).In a rodent study, it was observed that zinc behaves like an antidepressant (Nowak and others, 2005).
  • Cardiovascular System: Zinc performs a noteworthy role in the regulation of arterial blood pressure. Males and females were reported to metabolize zinc differently when suffering from hypertension (Tubek, 2007).
  • Liver: Zinc deficiency in the liver occurs not only in those with liver cirrhosis, but also in less advanced alcoholic and nonalcoholic liver disease (Bode and others, 1998).
  • Pregnancy: A mild deficiency of zinc during a pregnancy can cause increased maternal morbidity, abnormal taste sensation, prolonged gestation, inefficient labor, atonic bleeding, and an increased risk to fetuses (Jameson, 1993).
  • Diabetes: Zinc is very important in the synthesis, storage, and secretion of insulin (Chausmer 1998). A low level of zinc has been shown to play a role in diabetics with associated disease conditions such as coronary artery disease and several related risk factors including hypertension, and elevated levels of triglycerides (Singh and others, 1998).
  • Endocrine System: Studies show a correlation between zinc deficiency in geriatric patients and reduced activity of the thymus gland and thymic hormones, decreased response to vaccinations, and reduced immunity (Haase and Rink, 2009).
  • Healing: Zinc deficiency has been linked with delayed wound healing, and has been found to be crucial to the healing of gastric ulcers especially at the early stage (Kennan and Morris, 1993; Andrews and Gallagher-Allred, 1999; Watanabe, 1995).
  • Pneumonia: Zinc may shorten the duration of severe pneumonia and time in the hospital (Brooks, 2004).

World Health Organization - Zinc

WHO as of 2018

  • "Using food availability data, it is estimated that zinc deficiency affects about one-third of the world's population, with estimates ranging from 4% to 73% across subregions"
  • "Worldwide, zinc deficiency is responsible for approximately 16% of lower respiratory tract infections, 18% of malaria and 10% of diarrhoeal disease"
  • "Attributable DALYs were higher, with zinc deficiency accounting for about 2.9% of worldwide loss of healthy life years"

Good Zinc Overview - Dr. Jockers 2018
How To Test for Zinc
There are several ways to test zinc levels. One that I am a fan of due to its simplicity and cost-effectiveness is the zinc sulfate taste test. All you do purchase a bottle of zinc sulfate liquid (this a good one), place a capful in your mouth, and observe the sensations in your mouth.
Below are the possible outcomes and indications:

  • You Notice No Metallic Taste: Zinc Deficiency
  • You Notice A Delayed Metallic Taste: Slight Zinc Deficiency
  • You Notice Slight Metallic Taste: Zinc Levels Are Adequate, But Could Be Higher
  • You Notice Very Strong Metallic Taste: You Likely Have Optimal Zinc Levels

Cochraine Review - Zinc treats colds

2013 with free PDF
Zinc administered within 24 hours of onset of symptoms reduces the duration of common cold symptoms in healthy people but some caution is needed due to the heterogeneity of the data. As the zinc lozenges formulation has been widely studied and there is a significant reduction in the duration of cold at a dose of ≥ 75 mg/day, for those considering using zinc it would be best to use it at this dose throughout the cold. Regarding prophylactic zinc supplementation, currently no firm recommendation can be made because of insufficient data. When using zinc lozenges (not as syrup or tablets) the likely benefit has to be balanced against side effects, notably a bad taste and nausea.

Low Zinc was the best predictor of Vitamin D <20 ng in Iranian teenage girls - 2019

An Assessment of the Risk Factors for Vitamin D Deficiency Using a Decision Tree Model

Background and objectives: Vitamin D (25-hydroxyvitamin D or 25OHD) has a key role in the pathogenesis of several chronic disorders. Vitamin D deficiency is a common global public health problem. We aimed to evaluate the risk factors associated with vitamin D deficiency using a decision tree algorithm.

Methods: A total of 988 adolescent girls, aged 12-18 years old, were recruited to the study. Demographic characteristics, serum biochemical factors, all blood count parameters and trace elements such as Zinc, Copper, Calcium and SOD were measured. Serum levels of vitamin D below 20 ng/ml were considered to be deficiency. 70% of these girls (618 cases) were randomly allocated to a training dataset for the constructing of the decision-tree. The remaining 30% (285 cases) were used as the testing dataset to evaluate the performance of decision-tree.
In this model, 14 input variables were included: age, academic attainment of their father, waist circumference, waist to hip ratio, zinc, copper, calcium, SOD, FBG, HDL-C, RBC, MCV, MCHC, HCT. The validation of the model was assessed by constructing a receiver operating characteristic (ROC) curve.

Results: The results showed that serum Zn concentration was the most important associated risk factor for vitamin D deficiency. The sensitivity, specificity, accuracy and the area under the ROC curve (AUC) values were 79.3%, 64%, 77.8% and 0.72 respectively using the testing dataset.

Conclusions: The results suggest that the serum levels of Zn is an important associated risk factor for identifying subjects with vitamin D deficiency among Iranian adolescent girls.
