Zinc In The News Again

Zinc is such an important nutrient and involved in so many vital processes in the body, so I was not surprised to see mention of zinc in the news again.

This time it was an article in the NZ Herald written by Martin Johnston, with regard to Zinc deficiencies and children who have Autism.  You can read the full article here

Zinc, A VITAL Nutrient

Zinc, A VITAL Nutrient

He told us about a 2011 study of zinc concentrations in hair from 1967 children with autistic disorders, which found that nearly 50 per cent of those aged up to 3 years old had zinc deficiency. The rate was around 28 per cent for children aged 4 to 9 and dropped to around 3 per cent for those aged 10 to 15.

This is not surprising, when you consider that zinc is a mineral that is deficient in our soils here in New Zealand.

Before this report, we heard about the use of Zinc for sore throats and how using Zinc Lozenges can shorten the duration of common colds.

Scientist George Eby was contacted by Life Extension®, as he is the one who discovered that zinc can eradicate cold symptoms. George Eby has spent decades perfecting the most effective and palatable form and dose of zinc lozenge.

He talked about how his 3 year old daughter was the instigator of this research, while she was undertaking chemotherapy.  He tells us this

“From the first day of diagnosis, I regularly administered zinc and other supplemental nutrients to her. She was totally free of leukemic blast cells two-weeks after diagnosis and being given chemotherapy, radiation, and zinc which was unheard of at that time. Eventually, I published my hypothesis about zinc being vital for a rapid recovery from leukemia”.

Testing the theory

George recruited 2 well known doctors and undertook two clinical trials, one using 23 mg zinc gluconate tablets (used as throat lozenges), which were only one-half as potent as what their previous experience indicated was needed, and the other trial with 37 mg zinc orotate lozenges, used with 10 mmol zinc (gluconate) nasal spray.

The Conclusion for Zinc & The Common Cold

Upon analysis, they found that the 23 mg zinc gluconate lozenges, used every two hours (nine lozenges per day) shortened common colds by about seven days, with strong statistical significance (P=0.001).  Years later, they submitted the results for publication to Alternative Therapies in Health and Medicine.

30 years later this information was finally obtaining widespread acceptance of George’s discovery. Perhaps it’s not widespread yet, but zinc for common colds did get favorable mention in the April 2014 issue of the ultra-conservative Journal of the American Medical Association.

Leanne Loves Zinc & Takes It Daily

I personally take zinc every day.  When my immunity is lowered, I take a much large dose than usual, in separated doses.   Generally, I would not take any more than 100mg (elemental) of zinc in a day and would suggest you do not take any more than this, unless under the supervision of an experienced clinician.

George Eby goes on to tell us “Actually, that zinc is good for colds can be surmised from many years of research on zinc and the primary immune system. Without enough dietary zinc and other nutrients, our immune systems don’t function well and diseases are much more likely to develop and become difficult to remedy. Diet and immunity have been linked for centuries.  As we move away from meat-rich diets, our intake of zinc is becoming so low that it is threatening our immune system”.

Plus we need to remember that we are deficient in Zinc in our New Zealand soils, so it would be unlikely that most New Zealanders would have an adequate daily intake or have adequate stores of this mineral in their body.

Where is zinc stored in the body?

Henry Osiecki tells us that 90% of the body’s store of zinc is found in the muscles and bone.  However other “target organs” are the brain, optic nerve, eyes, in semen, the prostate gland, pancreas and adrenal glands. He tells us that the major route of zinc excretion is via the gastro intestinal tract.

Health associated zinc deficiency symptoms

Henry tells us that approximately 47% of the population is at risk of a zinc deficiency.

A deficiency of Zinc can cause retarded growth, delayed sexual maturity and prolonged healing of wounds.  As well as this, acne, alopecia, brittle nails, skin problems such as dermatitis, skin lesions and slow wound healing,  low testosterone, a low sperm count and sperm damage, decreased immune response and increased susceptibility to viral infections, depletion of B and T-cells, poor immunity, depression, DNA damage, impaired growth, impaired cognitive function, impotence, intercurrent infections, learning disorders, loss of appetite, loss of taste and smell, macular degeneration, manic depression, metabolic syndrome, moodiness, poor concentration and poor memory, poor vision, rough skin, neural tube defects, sleep problems, sore throats, sterility, viral infections and stretch marks can all be associated with a deficiency of zinc.

Interestingly, Henry tells use that white stretch marks indicate a relative deficiency, while red or purple stretch marks, indicate an absolute zinc deficiency.

 

 

Absorption of Zinc

Henry Osiecki tells us that the primary determinants of zinc absorption are the amount of zinc ingested and our dietary intake of foods high in phytates, which have a major effect on zinc bio-availability.  Phytates are mainly found in cereals and grains.

Other things that interfere with Zinc absorption include excess sugar intake, insufficient stomach hydrochloric acid and pancreatic enzymes, gut inflammation and allergy.

Excessive calcium intake impairs zinc absorption.  Zinc competes with calcium and iron for absorption.

A number of pharmaceutical drugs decrease zinc absorption.  These include H-2 receptor antagonists such as Cimetidine, Famotidine, Nizatidine and Ranitidine and Tetracycline – A group of antibiotics

A number of pharmaceutical drugs increase the urinary excretion of zinc.  These include, but are not limited to, ACE inhibitors, Corticosteroid medications, Loop diuretics and Penicillamine (a chelating agent).

A number of pharmaceutical drugs decrease zinc blood levels.  These include a number of Oral contraceptives and Valproic acid (used in Epilepsy)

A number of pharmaceutical drugs decrease body zinc levels.  These include the cholesterol lowering agents Clofibrate and Fenofibrate, Ethambutol for Tuberculosis (particularly in the heart, kidney and liver) and Zidovudine (formally AZT) an antiretroviral medication used to prevent and treat HIV/AIDS.

Other things that can affect zinc levels in the body are Alcohol, Beta blockers, Chlorthalidone, Cholestyramine, Cimetidine, EDTA, Endopril, Ethambutol, Penicillin, Pentobarbital, Polyphenols, Progesterone and Steroids.

Zinc and Copper are capable of decreasing absorption of the other from the digestive tract.   So if you have been taking Zinc and the level of this is not increasing in your body, it could be that you have high levels of copper in your body.  You can have this mineral tested from a blood test, to measure the amount in your blood (will not reveal the stored level is tissues).  Serum Copper is a non funded blood test in New Zealand and the cost of the test in September 2016 is NZ$52.

How much zinc do we need each day?

Henry Osiecki tells us that the Recommended Daily Amount of Zinc is 15mg or 0.2mg/kg, but that a Supplementary Range (a safe therapeutic dose for a range of disease states) is between 10-90mg.

The RDA by Age is:
Infants          5mg
<10 years    10mg
>10 years    15mg
Lactation   19mg

REMEMBER that a RDA relates to the amount you need to maintain your existing level in your body, so if you (like the rest of us) have low levels of Zinc in your body, you will need to take a lot more than the RDA.

Zinc Supplements Healthyonline Stocks

Our three main zinc supplements are:

Zinc Lozenges.  These use the exact form of zinc that George Eby found shortens the duration of the common cold, in a Lozenge form.

Zinc.  These Zinc tablets provide a therapeutic dosage of zinc in each tablet, with the co factors Vitamin A, manganese, magnesium & B6.

Zinc Fix Powder.  This powder is great for the whole family to use (5 years and older).  Each 1.9 grams of powder (1/2 metric tsp) provides 1000mg of Vitamin C, 23mg of Zinc and B6 & Beta Carotene.
