Zinc is a vital nutrient required by your body to be healthy and to protect against infections, heal wounds, metabolism, and reproductive functions. Stay informed with The Global Hues as we list the Top 10 Zinc Tablets Side Effects that may affect your health.
However, due to the inability of the body to retain zinc, several individuals resort to use of zinc tablets in order to stay healthy. These tablets are common, inexpensive and are very common when one is having a cold, infected, or deficient.
But also like any supplement, zinc tablets can have their downsides — especially if they’re misused or abused. Knowing what zinc tablets are, why individuals take them and the risks associated can help you make safe, informed choices. In this ultimate guide, we’re going to cover everything you need to know about zinc tablets – including their safe dosage and side effects – helping you with making smart supplement choices.
What Are Zinc Tablets?
zinc pills are oral dietary supplements that are meant to deliver an easy-absorbing amount of nutrients, an essential trace mineral required in more than 300 biological functions. Such tablets are of different strengths like 5 mg up to 50 mg in various forms, which include zinc gluconate, zinc acetate, zinc sulfate and zinc picolinate. All forms have a slight difference in absorption and tolerance.
Zinc pills are also commonly used to deal with deficiency, aid in immunity and help heal wounds, particularly when one does not get enough of it in a diet. Since supplements contain concentrated zinc, they can have immediate benefits—but at the same time, they have an increased risk of side effects in case of improper use.
Why Do People Take Zinc Supplements?
Zinc supplements are used by people due to a number of reasons. Immunity support is one of the most widespread, with zinc being an important part of immune cell activity and possibly reducing the practically shortening of the cold. Furthermore, it aids in the skin repair, wound healing, enzyme activity, reproductive system and taste and smell.
Individuals that consume poor diets, have digestive issues, experience high levels of stress, engage in a lot of training, or have chronic health conditions may not be able to balance the optimum amount of zinc intake with food only. The gap can be bridged by use of supplements. Nonetheless, zinc is effective, but only in the right proportions, and in case of unnecessary supplementation, it can produce the opposite of positive effects.
How Much Zinc Is Safe to Consume Daily?
Regarding adults, the adult dose of zinc is 11 mg in men and 8 mg in women on a daily basis. This entails both food and supplements of zinc. The Tolerable upper limit (UL) on the amount to be taken per day is 40 mg daily. The continuous surpassing of this limit may result in copper deficiency, anemia, lowered immunity, and other long-term problems.
Between 15–20 mg/day, short-term supplementation is generally safe for most healthy people, but anything higher should be taken with medical supervision. To avoid drug interaction or decreased effectiveness, zinc tablets should also be taken at least 2–3 hours apart from certain antibiotics.
Is There a Safe Way to Take Zinc Tablets?
Zinc tablets are better at reducing side effects when used with food because when used on an empty stomach, there is a high possibility of nausea and stomach cramps. Furthermore, it should not be taken with large amounts of calcium or iron supplements, as these two interact and compete for absorption.
Individuals who are taking antibiotics like tetracycline or fluoroquinolones must take zinc at least 23 hours apart. Also, zinc products placed into the nose must not be used because a loss of smell is reported. Adherence to these instructions will reduce the level of discomfort and increase the safety of the supplements.
Top 10 Zinc Tablet Side Effects You Should Know Before Taking Them
Zinc pills are not without advantages, however, there are multiple side effects that can be caused by the inappropriate use and dosage. The top 10 ones that you need to know in this case are as follows and classified.
1. Abdominal Discomfort and Cramps.
It is common to hear many people complain of stomach cramps, bloating or a burning feeling when using zinc supplements. This is as a result of concentrated zinc which intensifies the stomach acid. Zinc can be taken with a larger meal to help relieve discomfort, or zinc can be taken in slow-release formulations. Those with sensitive digestion or pre-existing gastrointestinal problems should begin with low dosages and monitor the response of their body.
2. Diarrhea or Digestive Upset
Zinc can cause digestive imbalance and in higher doses, can also cause loose stools or diarrhea. Along with the cramping or nausea, the bowel may not accommodate the number of minerals and excess diarrhea may occur. Generally, staying hydrated and reducing the dose is effective. Chronic diarrhea may be a sign that zinc doesn′t suit your body type.
3. Metallic Taste or Mouth Irritation.
Another side effect that is popular with zinc tablets and lozenges is a metallic or bitter taste. This is a temporary taste disturbance, which is referred to as the zinc taste and can last between a few minutes and days. Zinc pills can also produce mild mouth irritation in a few instances. Although it is not damaging, the bitter flavor is irritating. This effect can be easily reduced by swallowing the pill instantly and then taking a glass of water.
4. Copper Deficiency (Caused by Long-term High Doses)
Taking excessive zinc over prolonged periods of time may cause copper deficiency due to interference in copper absorption. This can result in anemia, weakness, numbness and nerve paralysis. Individuals exceeding 40 mg zinc/day over months are the ones who are at risk. The side effect of consuming zinc that can be most severe in the long run is copper deficiency, and therefore it is necessary to monitor the dose and the duration.
5. Nausea and Vomiting
This is the worst side effect of zinc pills particularly when taken on an empty stomach. Large doses may cause irritation of the stomach lining leading to nausea, vomiting, or feel of being queasy soon after taking it. Intake of zinc along with a meal or replacing with a milder form (such as zinc picolinate) can also be beneficial to alleviate the symptoms. In case nausea is still experienced even after eating, then the dose is probably too high or the supplement is not the right one.
6. Reduced HDL (“Good”) Cholesterol.
Research has established that zinc in very high doses—over 50mg/day can lower the level of HDL cholesterol. HDL has a role in the health of the heart, and decreasing it may put a person at risk of cardiovascular problems in the long term. An occasional, although often harmless, high dosages are safe but chronic high dosage should be avoided. Persons having cholesterol issues or heart diseases need to consult with the doctor before taking zinc in supplements.
7. Immune Suppression Due to Overdose
And while zinc does work to support immunity at healthy levels, excessive zinc can suppress it. Too much zinc disturbs the balance among immune cells and might lessen the body’s capacity to fight infections. This is the kind of effect that tends to emerge in people taking very large amounts over a very long time. The thing is balance: Not enough zinc can lower immunity, but so can long-term over-supplementation.
8. Mineral Imbalance
Since zinc, copper and iron compete for absorption in the gut, excessive zinc can upset the balance of other minerals. This may result in tiredness, weakness, or worsening anemia for some patients. Those with pre-existing iron deficiency, chronic illness or digestive issues should supplement zinc carefully to avoid preventing your body from absorbing other key nutrients.
9. Reduced Effectiveness of Certain Medications
Certain antibiotics — tetracyclines and fluoroquinolones, in particular — are less effective when they come into contact with zinc. It might also interact with penicillamine (prescribed for rheumatoid arthritis) and some diuretics. To prevent interactions, zinc should be separated in time from these medications by at least 2–3 hours. If you have to take medication for a long period of time, talk to your healthcare provider before incorporating zinc tablets.
10. Loss of Smell
Even though this is nasal zinc, and not a tablet, it’s still significant to mention. Intranasal zinc sprays and gels have been associated with anosmia — the permanent or long-lasting loss of smell. Due to this risk, patients are advised not to use any type of zinc-containing nasal products. Tablet and oral varieties don’t contain this risk, but people should keep an eye out for the differences in products.
