Liquid zinc sulfate was first developed by Dr Bryce Smith for the treatment of anorexia, a condition whereby the ‘zinc blockade’ exists causing a defect in the mucosal absorption mechanisms dependent on zinc.  T J Clark’s catalysed zinc is the most advanced zinc supplement, providing zinc sulfate in a colloidal form with the addition of a mineral catalyst.  Our catalyzed zinc is recognised as the most reliable form of zinc to replenish zinc levels, regardless of an individual’s mucosal absorption ability.  T J Clark’s catalyzed zinc is flavoured for optimal patient compliance and is the only liquid zinc supplement available through health stores.

Each 5ml contains
Elemental Colloidal Zinc Sulfate
Phytogenic Mineral Catalyst          
(Containing but not limited to B, Ca, Cr, Co, Cu, I, Fe, Li, Mg, Mn, Mo, P, K, Se, Si, Sr, V, Zn)

Inactive Ingredients:
Purified water, Organic Vanilla Flavor, Natural Cane Sugar, Potassium Sorbate (0.1%)
Pharmacology and Research of Active Ingredients:
  • Zinc is an essential element in human and animal nutrition with a wide range of biological roles. Zinc plays catalytic, structural or regulatory roles in the more than 200 zinc metalloenzymes that have been identified in biological systems. These enzymes are involved in nucleic acid and protein metabolism and the production of energy, among other things. Zinc plays a structural role in the formation of the so-called zinc fingers. Zinc fingers are exploited by transcription factors for interacting with DNA and regulating the activity of genes. Another structural role of zinc is in the maintenance of the integrity of biological membranes resulting in their protection against oxidative injury.
  • Zinc is required for a number of immune functions, including T-lymphocyte activity. Zinc deficiency results in thymic involution, depressed delayed hypersensitivity, decreased peripheral T-lymphocyte count, decreased proliferative T-lymphocyte response to phytohemagglutinin (PHA), decreased cytotoxic T-lymphocyte activity, depressed T helper lymphocyte function, depressed natural killer cell activity, depressed macrophage function (phagocytosis), depressed neutrophil functions (respiratory burst, chemotaxis) and depressed antibody production.
  • Zinc may have secondary antioxidant activity. Zinc does not have redox activity under physiological conditions. Zinc may influence membrane structure by its ability to stabilize thiol groups and phospholipids. It may also occupy sites that might otherwise contain redox active metals such as iron. These effects may protect membranes against oxidative damage. Zinc also comprises the structure of copper/zinc-superoxide dismutase (Cu/Zn-SOD). Zinc plays a structural role in Cu/Zn-SOD. Zinc may also have antioxidant activity via its association with the copper-binding protein metallothionein.
  • Supplementation with zinc reduced the incidence of childhood pneumonia by 41% and incidence of diarrhoea in children by 25%, according to the findings of a review of ten randomized, controlled studies in the developing world.
  • Disturbances in metabolism, as well as zinc deficiency, have been associated with some inflammatory conditions, including some inflammatory bowel diseases and rheumatoid arthritis.  Diminished zinc status has been associated with HIV disease and higher incidence of opportunistic infections.  Zinc supplementation has produced higher CD4+ lymphocyte cell counts and reduced incidence of bacterial infections among patients with HIV disease in one study.  Zinc plays many roles in pregnancy, and disturbances in zinc metabolism, as well as zinc deficiency, can have serious adverse effects on the course of pregnancy and upon the growth of the fetus and newborn. Zinc deficiency can be teratogenic, producing neural tube defects. Zinc is also very important to the newborn when breast milk may be its only source of zinc (during the first few months of life).  
  • Phytogenic Mineral Catalyst – Our Polyfloramin™extracts contain up to 72 trace elements for enhanced bioavailability, assimilation and synergy of the active ingredients contained in our Zinc formula.  Due to the fact that high doses of zinc can interact with the absorption of iron and copper, our mineral catalyst contains a balance of these elements to reduce the incidence of further mineral depletion.
Clinical Applications:

T J Clark’s Catalyzed Zinc formula may be beneficial in the prevention and treatment of:

  • Acne, anorexia, atherosclerosis, atopic dermatitis, benign prostatic hyperplasia, chemical sensitivity, Crohn’s disease, immune depression, and recurring infections.
  • Leukonychia (white spots on finger nails), loss of taste and smell, osteoporosis, PMT, and psoriatic arthritis.
  • Low testosterone, low sex drive, low sperm count and fertility, loss of weight and muscle mass, growth retardation, poor appetite, and dementia. 
  • Doses of zinc up to 40 milligrams daily are generally well tolerated. Higher doses may cause adverse reactions. The most common adverse reactions are gastrointestinal and include nausea, vomiting and gastrointestinal discomfort. Other adverse reactions include a metallic taste, headache and drowsiness. There are some reports of decreased HDL-cholesterol in those taking high doses of zinc. Chronic intake of high doses of zinc can lead to copper deficiency and hypochromic, macrocytic anaemia secondary to zinc-induced copper deficiency.
  • High doses of zinc may be immunosuppressive.
  • Zinc should be taken apart from high fibre foods for maximum absorption.  Zinc does not appear to interact negatively with medication.
