What is zinc overdose and how do I know the symptoms and signs? These are common questions and we have all the answers for you!
Zinc is a vital mineral that is involved in more than 100 chemical reactions that occur in your body.
It is essential to grow DNA synthesis, regular taste sensation. It also assists in the healing of wounds as well as reproductive health.
Health authorities have established the maximum tolerable intake (UL) in zinc as 40 mg per day for adults. This is the maximum recommended daily dose of the mineral. Most people will find this amount of nutrients is not likely to have negative consequences.
Sources of zinc-rich food include poultry, red meat seafood, whole grain and cereals fortified with zinc. Oysters have the highest content of zinc in zinc, with up to 493 percent of the daily amount in a 3 ounce (85-gram) portion.
While some foods may provide quantities that are higher than the UL There are no reports of zinc poisoning resulting from natural zinc found in food.
But, the poisoning of zinc can result from supplements to the diet like multivitamins, or from accidental consumption of household products containing zinc.
Here are the seven most frequent indicators and signs of a zinc overdose.
1. Nausea and Vomiting
The vomiting and nausea of nausea is the most commonly mentioned as a side effect of toxic zinc.
A study of 17 studies about the efficacy of zinc supplements to treat common colds revealed that zinc supplementation can decrease the time it takes to get a cold however, adverse reactions were not uncommon. In actual fact 46% of people who participated in the study reported feeling nausea.
Doses that exceed 250 mg are considered to be emetic, meaning that vomiting is probable and may happen quickly. In one instance, extreme nausea and vomiting occurred within 30 minutes after taking a single dose of zinc of 560 mg.
But vomiting can happen even at lower doses. In a six-week study of healthy subjects taking 150 mg zinc daily, more than half of them experienced nausea and vomiting.
While vomiting can aid in the elimination of excessive amounts of zinc but it isn’t enough to avoid further complications.
If you’ve consumed excessive amounts of zinc, get medical attention immediately.
The vomiting and nausea of nausea is typical and usually immediate reactions to the consumption of toxic levels of zinc.
2. Stomach Pain and Diarrhea
Typically, stomach discomfort and diarrhea can occur together with vomiting and nausea.
In a study of 17 studies about zinc supplements and common colds about 40% of the participants complained of diarrhea and abdominal pain.
While less frequent than gastrointestinal irritation, stomach bleeding have been mentioned.
In one case study one patient experienced bleeding in the intestine following the intake of 220 mg zinc sulfate every day to treat acne.
In addition, zinc chloride higher than 20% have been reported to cause severe corrosive damage to the digestive tract.
Zinc chloride isn’t used in supplements to eat, but poisoning can result from the accidental consumption of household items. Soldering fluxes cleaners, as well as wood-finishing products all contain zinc chloride.
Stomach symptoms like diarrhea and stomach pain are typical symptoms of toxic zinc. In rare cases, severe bleeding and damage to the gastrointestinal tract may occur.
3. Flu-Like Symptoms
Utilizing more zinc than prescribed UL can result in flu-like symptoms including chills, fever cough, headache, and fatigue.
These symptoms can be seen in various situations, which includes the other toxicities of minerals. Therefore, identifying the toxicity of zinc can be a challenge.
Your doctor might require an extensive medical and dietary background, along with blood tests for suspect mineral toxicity.
When you’re using supplements be sure to report these to your physician.
The symptoms of flu can be because of toxic levels of various minerals, such as zinc. It is therefore essential to inform any supplements you take to your doctor for proper treatment.
4. Low “Good” HDL Cholesterol
“Good” HDL cholesterol lowers the risk of developing heart disease by removing cholesterol from your cells, keeping your arteries clear of plaque.
Health professionals for adults suggest that you have an HDL that is greater of 40 mg/dL. Low levels can put you at chance of developing heart disease.
A look at a variety of studies on the relationship between zinc and cholesterol levels indicates that taking over 50mg zinc daily could reduce the “good” HDL levels and will not affect cholesterol levels “bad” LDL cholesterol.
The study also shows that 30 milligrams of zinc a daywhich is less than UL for zinc did not have any effect on HDL in the period of up to 14 weeks.
Although a variety of factors can influence cholesterol levels this research is something to take into consideration if you use zinc supplements often.
A regular intake of zinc that is higher than the suggested levels could result in the reduction of “good” HDL cholesterol levels that could place you at a greater risk of developing heart disease.
5. Changes in Your Taste due to Zinc Overdose
Zinc is crucial to our sense of flavor. A zinc deficiencies can lead to the condition hypogeusia. It is an impairment in the ability to detect taste.
It is interesting to note that zinc levels over of what is recommended levels can result in taste changes that include a sour flavor or metallic smell in your mouth.
The majority of the time the symptom is mentioned in studies that study zirconium lozenges (cough drops) or liquid remedies for common cold.
While some studies show positive results, the dosages typically exceed the recommended dose of 40 mg daily and adverse reactions are quite common.
For instance 14% of participants in a study lasting just one week complained of taste changes after dissolving zinc tablets of 25 mg in their mouths each two hours when they were awake.
In a different study that used the supplement in liquid form 53percent of the subjects complained of metallic taste. It’s not clear the duration of these symptoms.
If you’re taking zinc lozenges or other liquid supplements be aware that symptoms can occur regardless of whether the product is used according to the directions.
Zinc is a key ingredient in the perception of taste. In excess, zinc can create a metallic taste in your mouth, particularly when consumed as a chewable or as a liquid supplement.
6. Copper Deficiency
Copper and zinc compete for absorption in the small intestinal.
Doses of zinc that exceed the recommended UL can hinder the body’s ability of absorbing copper. As time passes, this may result in a copper deficiency.
Similar to zinc as well, copper is an important mineral. It assists in the absorption of iron as well as metabolism, which makes it essential to make red blood cells. It also plays a part in the formation of white blood cells.
Red blood cells carry oxygen throughout your body and white blood cells play a major role as components of your immune system.
Copper-induced zinc deficiency can be connected to several blood diseases.
Anemia due to iron deficiency Anemia caused by a lack Red blood cell health because of the insufficient iron levels in your body.
Sideroblastic anemiais a deficiency in healthy blood vessels as a result of the inability of iron to be metabolized effectively.
Neutropenia: The absence in healthy white blood cells as a result of an interruption in their production.
If you are deficient in copper Do not combine your supplementation with zinc.
Regular intakes of zinc over 40 mg daily may inhibit copper absorption. This can lead to copper deficiency that is linked to a variety of blood disorders.
7. Frequent Infections due to Zinc Overdose
While zinc plays a crucial role in the functioning of your immune system however, too much zinc could hinder your immune response.
This is often an result of neutropenia and anemias However, it has been proven to occur without the presence of zinc-induced blood disorders.
In studies conducted in test-tubes, excess zinc diminished the functionality of T cells. They are a kind of white blood cells. T cells play a crucial part in the immune system through their attachment to and destruction of harmful pathogens.
Human studies support this, however, results aren’t as consistent.
A small study of 11 healthy men revealed an increase in immune function after they consumed the zinc equivalent of 150 milligrams once each daily during six weeks.
However, taking 100 mg of zinc per every day for a month produced mixed results for older adults. Some had a diminished immune response, whereas others experienced an increased response.
Supplementing with zinc in amounts over the UL can reduce your immune system, making you more prone to illnesses and infections.
Treatment Options for Zinc Overdose
If you think you might be suffering from zinc poisoning make contact with your local poison control centre immediately.
Zinc poisoning can be life-threatening. It is therefore important to seek medical assistance as soon as you notice symptoms.
It may be recommended to drink milk as the large amounts in calcium as well as phosphorus present in it may inhibit zinc absorption in the digestive tract. The activated charcoal has the same impact.
Chelating agents are also employed in serious poisoning cases. They aid in the elimination from excess zinc through binding it in blood. It is then flushed out in your urineinstead of being infiltrating into your cells.
Zinc poisoning can be a life-threatening issue. It is crucial to seek medical attention immediately.
The Bottom Line
While some foods have zinc at levels that are higher than that UL of 40 mg/day There have been no reports of poisoning resulting from zinc naturally found in food items have been reported. We hope you can stay safe from Zinc Overdose!
But, an overdose of zinc may occur due to dietary supplements or from accidental consumption.
Zinc toxicity can cause long-term and acute consequences. The severity of symptoms can be determined by the amount and duration of consumption.
In the event of an acute intake of large doses of zinc digestive symptoms can be expected. In the most severe instances such as accidental consumption of household products containing zinc the gastrointestinal bleeding and corrosion could occur.
In the long run, it can result in some less severe but more immediate negative side effects, like the low “good” HDL cholesterol, copper deficiency, and an immune system that is suppressed.
All in all, you should only over the recommended UL with the guidance by medical professionals.
