Our colloidal generator will make 5 litres of colloidal zinc and also colloidal silver, colloidal magnesium, colloidal gold. Zinc is friendly to the environment and human health. Zinc is a natural constituent of soil and is second only to iron as a metal naturally present in the human body. The National Research Council has established a Recommended Dietary Allowance (RDA) of 30 mg of zinc for human consumption.
Zinc inhibits the proliferation of many viruses, moss, fungus, algae and mildew.
Zinc mineral water ( Colloidal Zinc) can be made using our colloidal generator
The body contains 2 to 3 g of zinc (Zn), found mainly in bones, teeth, hair, skin, liver, muscle, leukocytes, and testes. One third of the 100 Âµg/dL (15.3 Âµmol/L) of zinc found in plasma is attached loosely to albumin, and about 2/3 is firmly bound to globulins. There are > 100 zinc metalloenzymes, including a large number of nicotinamide adenine dinucleotide (NADH) dehydrogenases, RNA and DNA polymerases, and DNA transcription factors as well as alkaline phosphatase, superoxide dismutase, and carbonic anhydrase. Dietary intake of zinc by healthy adults varies from 6 to 15 mg/day, and absorption is about 20%. Meat, liver, eggs, and seafood (especially oysters) are good sources. The RDA is 0.2 mg/kg/day for adults.
Deficiency: The signs and symptoms of zinc deficiency include anorexia, growth retardation, delayed sexual maturation, hypogonadism and hypospermia, alopecia, immune disorders, dermatitis, night blindness, impaired taste (hypogeusia), and impaired wound healing. The first signs of zinc deficiency in marginally nourished children are suboptimal growth, anorexia, and impaired taste. The most serious manifestations of zinc deficiency were reported in Iranian dwarfs. These adolescent boys, who consumed large amounts of clay, were retarded in growth and sexual development and had anemia, hypogonadism, hepatosplenomegaly, rough skin, and mental lethargy. After treatment with a well-balanced diet containing adequate amounts of zinc for 1 yr, pubic hair appeared, sexual organs increased in size, linear growth was resumed, and the skin became normal. The anemia responded to iron supplements. Zinc deficiency develops in some patients with cirrhosis because the ability to retain zinc is lost.
Biochemical signs associated with zinc deficiency include decreased levels of plasma zinc (< 70 Âµg/dL [< 10.7 Âµmol/L]), alkaline phosphatase, alcohol dehydrogenase in the retina (which accounts for night blindness), and plasma testosterone as well as impaired T-lymphocyte function, decreased collagen synthesis (resulting in poor wound healing), and decreased RNA polymerase activity in several tissues.
Clinical assessment of mild zinc deficiency is difficult because many of the signs and symptoms are nonspecific. Nonetheless, if a malnourished person has a borderline-low plasma zinc level, is subsisting on a high fiber and phytate diet containing whole-grain bread (which reduces zinc absorption), and has reduced taste sensitivity, an impaired lymphocyte response to mitogens, and reduced gonadal hormone function, then zinc deficiency should be suspected, and treatment with zinc supplements (15 to 25 mg/day) should be tried.
Maternal zinc deficiency may cause anencephaly in the fetus. Secondary deficiency occurs in liver disease, in malabsorption states, and during prolonged parenteral nutrition. Night blindness and mental lethargy may be features.
Acrodermatitis enteropathica--a rare autosomal recessive, once fatal disorder--results from malabsorption of zinc. The defect involves the failure to generate a transport protein that enables zinc to be absorbed in the intestine. Symptoms usually begin after an infant is weaned from breast milk. This disorder is characterized by psoriasiform dermatitis, hair loss, paronychia, growth retardation, and diarrhea. Zinc sulfate 30 to 150 mg/day orally results in complete remission.
Toxicity: Ingesting zinc in large amounts (200 to 800 mg/day), usually by consuming acidic food or drink from a galvanized container, can cause vomiting and diarrhea. Doses of zinc ranging from 100 to 150 mg/day interfere with copper metabolism and cause hypocupremia, RBC microcytosis, and neutropenia. Metal fume fever, also called brass-founders' ague or zinc shakes, is an industrial hazard caused by inhaling zinc oxide fumes; it results in neurologic damage.
Is Zinc toxic?
Only to fungus type organisms (fungus, moss, algae and mildew).
The addition of zinc to standard antimicrobial treatment may accelerate recovery from pneumonia, say researchers in this week's issue of THE LANCET.
Pneumonia is a leading cause of mortality and morbidity in children less than five years old. Zinc is reported to prevent pneumonia, and to prevent and treat diarrhoea, and it may boost the body's immune response to infection.
W Abdullah Brooks and colleagues from the International Centre for Diarrhoeal Disease Research,
Children given zinc recovered from severe pneumonia an average of one day earlier than did those given placebo, and their average stay in hospital was one day shorter. The zinc supplement was safe and well tolerated. Since a course of zinc treatment costs only US$0Â·15, and one day in the study hospital costs US$25, the potential cost savings are substantial.
Dr Brooks comments: "The effects on treatment failure are striking, have significant implications for reduction of antimicrobial resistance by decreasing multiple antibiotic exposures, and could help reduce complications and death in situations where second line drugs are not available."

What does it do? Zinc is a component of more than 300 enzymes needed to repair wounds, maintain fertility in adults and growth in children, synthesize protein, help cells reproduce, preserve vision, boost immunity, and protect against free radicals, among other functions.
In double-blind trials, zinc lozenges have reduced the duration of colds in adults,123 but have been ineffective in children.4 The ability of zinc to shorten colds may be due to a direct, localized anti-viral action in the throat. For the alleviation of cold symptoms, lozenges providing 13-25 mg of zinc, in the form of zinc gluconate, zinc gluconate-glycine, or zinc acetate, are used, typically every two hours while awake, but only for several days. The best effect is obtained when lozenges are used at the first sign of a cold.
Lozenges containing zinc gluconate, zinc gluconate-glycine, or zinc acetate have been effective, whereas most other forms of zinc and lozenges flavored with citric acid,5 tartaric acid, sorbitol, or mannitol, have been ineffective.6 Trials using forms other than zinc gluconate, zinc gluconate-glycine, or zinc acetate have failed, as have trials that use insufficient amounts of zinc.7 Therefore, until more is known, people should only use zinc gluconate, zinc gluconate-glycine, or zinc acetate.
Zinc reduces the body's ability to utilize the essential mineral copper. (For healthy people, this interference is circumvented by supplementing with copper, along with zinc.) The ability to interfere with copper makes zinc an important therapeutic tool for people with
Zinc supplementation in children in developing countries is associated with improvements in stunted growth, increased weight gain in underweight children, and substantial reductions in the rates of diarrhea and pneumonia, the two leading causes of death in these settings.8910 Whether such supplementation would help people in better nourished populations remains unclear.
A small, preliminary trial has found zinc sulfate to be effective for contact dermatitis (a skin rash caused by contact with an allergen or irritant).11 Participants with active skin rashes took approximately 23 mg of zinc (in the form of zinc sulfate) three times daily, for one month. 73% of those taking the zinc sulfate had complete resolution of their skin rashes, while the remaining participants had a 50-75% improvement. Further trials are needed to confirm these preliminary findings, however.

Who is likely to be deficient? Zinc deficiencies are quite common in people living in poor countries. Phytate, a substance found in unleavened bread (pita, matzos, and some crackers) significantly reduces absorption of zinc, increasing the chance of zinc deficiency. However, phytate-induced deficiency of zinc appears to be a significant problem only for people already consuming marginally low amounts
Even in developed countries, low-income pregnant women and pregnant teenagers are at risk for marginal zinc deficiencies. Supplementing with 25-30 mg per day improves pregnancy outcome in these groups.1213
People with liver cirrhosis appear to be commonly deficient in zinc.14 This deficiency may be due to cirrhosis-related zinc malabsorption.15
People with Down's syndrome are also commonly deficient in zinc.16 Giving zinc supplements to children with Down's syndrome has been reported to improve impaired immunity17 and thyroid function,18 though optimal intake of zinc for people with Down's syndrome remains unclear.
Children with alopecia areata (patchy areas of hair loss) have been reported to be deficient in zinc.1920
The average diet frequently provides less than the Recommended Dietary Allowance for zinc, particularly in vegetarians. To what extent (if any) these small deficits in zinc intake create clinical problems remains unclear. Nonetheless, a low-potency supplement (15 mg per day) can fill in dietary gaps. Zinc deficiencies are more common in alcoholics and people with sickle cell anemia, malabsorption problems, and chronic kidney disease.21
How much is usually taken? Moderate intake of zinc, approximately 15 mg daily, is adequate to prevent deficiencies. Higher levels (up to 50 mg taken three times per day) are reserved for people with certain health conditions, under the supervision of a doctor. For the alleviation of cold symptoms, lozenges providing 13-25 mg of zinc in the form zinc gluconate, zinc gluconate-glycine, or zinc acetate are generally used frequently but only for several days.
Are there any side effects or interactions? Zinc intake in excess of 300 mg per day has been reported to impair immune function.22 Some people report that zinc lozenges lead to stomach ache, nausea, mouth irritation, and a bad taste. One source reports that gastrointestinal upset, metallic taste in the mouth, blood in the urine and lethargy can occur from chronic oral zinc supplementation over 150 mg per day,23 but those claims are unsubstantiated. In topical form, zinc has no known side effects when used as recommended.
Preliminary research had suggested that people with Alzheimer's disease should avoid zinc supplements.24 More recently, preliminary evidence in four patients actually showed improved mental function with zinc supplementation.25 In a convincing review of zinc/Alzheimer's disease research, perhaps the most respected zinc researcher in the world concluded that zinc does not cause or exacerbate Alzheimer's disease symptoms.26
Zinc inhibits copper absorption. Copper deficiency can result in anemia, lower levels of HDL ("good") cholesterol, or cardiac arrhythmias.272829 Copper intake should be increased if zinc supplementation continues for more than a few days (except for people with Wilson's disease).30 Some sources recommend a 10:1 ratio of zinc to copper. Evidence suggests that no more that 2 mg of copper per day is needed to prevent zinc-induced copper deficiency. Many zinc supplements include copper in the formulation to prevent zinc-induced copper deficiency. Zinc-induced copper deficiency has been reported to cause reversible anemia and suppression of bone marrow.31
Marginal zinc deficiency may be a contributing factor in some cases of anemia. In a study of women with normocytic anemia (i.e., their red blood cells were of normal size) and low total iron-binding capacity (a blood test often used to assess the cause of anemia), combined iron and zinc supplementation significantly improved the anemia, whereas iron or zinc supplemented alone had only slight effects.32 Supplementation with zinc, or zinc and iron together, has been found to improve vitamin A status among children at high risk for deficiency of the three nutrients.33
Zinc competes for absorption with copper, iron,3435 calcium,36 and magnesium.37 A multi-mineral supplement will help prevent mineral imbalances that can result from taking high amounts of zinc for extended periods of time.
N-acetyl cysteine (NAC) may increase urinary excretion of zinc.38 Long-term users of NAC may consider adding supplements of zinc and copper.
