Taking Zinc Can Make You Feel Sick
Dont go popping zinc supplements every day thinking you’re reinforcing your immune system. The amount of zinc you need daily is 11 mg for men and 8 mg for women. And the Institute of Medicine has set the tolerable upper intake level at 40 mg for adults. Studies looking at zincs potential to help shorten or reduce the intensity of colds or other respiratory illnesses have involved daily doses of up to 100 mg, but just for the duration of the illness. If youre taking zinc on an ongoing basis, going over the upper limit can cause health problems, including nausea, vomiting, stomach cramps, diarrhea, and low copper levels, Haggans says. Zinc supplements and lozenges can also leave a metallic taste in your mouth, Thomas says.
Nasal sprays containing zinc were popular cold remedies until the FDA warned that using them could cause you to lose your sense of smell. As a result, most nasal sprays have either been reformulated without zinc or taken off the market. Theres no evidence that zinc pills or lozenges cause this side effect, though.
Zinc And Pregnant/breastfeeding Women
Pregnant women and women who are breastfeeding should take between 11 to 13mg a day, depending on their age.
Ideally, we should all be able to get this zinc from our daily diet.
However, if we have too much of it, then it can impact our bodys ability to absorb copper, which can lead to anaemia and make our bones weaker.
Zinc is lost through sweat, making supplementation very important for athletes, who dont get a lot of zinc through their daily diet
Thats why, if you are taking zinc supplements, its important not to exceed the recommended guidance.
Do not take more than 25mg of zinc tablets a day, unless you have been told otherwise by your GP.13
If you are deficient in zinc, then you may experience one or more of the following symptoms:14,15
- Low insulin levels

How Do I Get Enough Zinc
Zinc is found in many foods such as meat, fish, poultry, cereals and dairy foods. The amount of zinc the body can absorb is affected by how much protein is in the diet, so vegetarians and vegans, or people on long-term restricted diets, are more likely to experience zinc deficiency.
Some people may need more zinc than they can get from food alone. Zinc can be found in zinc supplements or multi-vitamin supplements and cold remedies that contain zinc.
Take A Safe Zinc Supplement
As these studies and case reviews clearly illustrate, the safest way to approach zinc supplementation is with a low dose designed to supplement a healthy diet of foods containing zinc. This helps reduce the risk of suffering from a zinc overdose and lowers the risk of developing a copper deficiency.
Immune Super Boost contains 20 mg of zinc along with helpful natural ingredients such as elderberry extract and echinacea that help your body build a strong immune system.â Healthycell’s gel liquid vitamin for adults contains nutrients that have been shown to slow viral replication and help support your body’s ability to protect against infection.â With advanced MICROGEL technology, absorption is improved by providing small, soluble, nutrient particles that are absorbed in the digestive tract, making this type of supplementation more effective than pills.
If you prefer to take a multivitamin that also supports your body’s zinc needs, the Bioactive Multi and Vegan Essentials are excellent multivitamin options with 11 mg of zinc each. Before beginning any zinc supplement it is important to consult with your doctor and disclose all supplements to ensure that you are not at risk for copper deficiency.

Is Too Much Zinc Bad For You
We have already touched upon the dire health and performance effects of too little zinc, but can too much of this trace element also cause any problems?
Potentially yes. Again, if you are an athlete or perform regular bouts of intense activity, your requirements may be different.
However, in more normal circumstances, and while we appreciate that there is not always a one-size-fits-all solution to nutrition zinc toxicity can occur.
Health Benefits Of Zinc
In addition to its role in supporting the immune system, zinc is required for the activity of more than 300 enzymes that aid with healthy digestion, nerve function, and metabolism.
Zinc also supports brain health. Compared to other organs in the body, zinc concentration is highest in the brain. A 2017 study, published in the International Journal of Molecular Sciences, concluded that while there are many unknowns, changes in zinc balance in the brain may affect conditions that include age-related cognitive decline, depression, and Alzheimers disease.
Another of zincs major roles is helping the body heal. Zinc is required for cell membrane repair, cell growth, and the maintenance of healthy skin. Zinc-dependent proteins play fundamental roles within cells, including in DNA repair. For these reasons, a zinc deficiency can lead to skin problems and impaired wound healing.
Too little zinc can negatively impact your senses and appetite. According to one recent study, 35% to 45% of adults 60 and older had zinc intakes below the estimated average requirement. One set of side effects tied to zinc deficiency involves diminished taste and smell, plus poor appetite. If youve ever lost these senses due to illness, youre aware of how much they affect the appeal of food. In healthy adults, zinc plays a role in maintaining these functions.

- 913 years: 8 mg
- 1418 years : 11 mg

Zinc deficiency isnt common in the United States, though there are some groups of people who are at an increased risk, including:
- People with gastrointestinal issues, such as Crohns disease and ulcerative colitis, because zinc can be lost through the gastrointestinal tract
- People with sickle cell disease, because they may require more zinc
- Vegetarians, because they miss out on zinc-rich meat and seafood
- Pregnant women, because the growing baby requires extra zinc
- Alcoholics, because they have a decreased ability to absorb the nutrient and an increased likelihood of passing it when they go to the bathroom

What Are The Risks Of Taking Zinc
- Side effects. Zinc supplements can irritate the stomach and mouth. Zinc lozenges can alter your sense of smell and taste for a few days. If taken long-term, zinc lozenges may lower copper levels in the body. Zinc nasal sprays have been associated with a loss of smell, which may be permanent.
- Interactions. Zinc may interact with some medicines such as birth control pills and some antibiotics. Zinc can also interact with other supplements, such as calcium, magnesium, copper, and iron. If you take daily medicine or supplements, ask your healthcare provider about taking zinc.
- Risks. People who are allergic to zinc, have HIV, or have hemochromatosis should not take zinc supplements without talking to their doctor first. Too much zinc can cause fever, cough, nausea, reduced immune function, mineral imbalances, cholesterol changes, and other issues. In pregnant women, high doses may harm the fetus.
Is It Ok To Take Vitamin D Everyday
Current guidelines say adults shouldnt take more than the equivalent of 100 micrograms a day. But vitamin D is a fat-soluble vitamin, so your body can store it for months and you dont need it every day. That means you could equally safely take a supplement of 20 micrograms a day or 500 micrograms once a month.

How Much Salt Do I Need
You should have no more than 6g of salt a day.
But, on average, people in the UK eat approximately 8g of salt a day, which is much more than the body needs.
A few practical tips for cutting down on salt include:
- check food labels and choose foods with less salt where colour-coded labels are used, try to pick products with more greens and ambers, and fewer reds, for a healthier choice
- choose tinned vegetables and pulses with no added salt
- choose tinned fish in spring water rather than brine
- only use sauces like soy sauce, brown sauce, ketchup and mayonnaise sparingly, as these are often high in salt
- eat fewer salty snacks, such as crisps, salted nuts, and salty foods such as bacon, cheese, pickles and smoked fish
- add less or no salt when cooking use herbs and spices for flavour instead
- choose low-salt stock cubes, or make your own stock without added salt
- taste your food first, and do not automatically add extra salt
You can also download the Change4Life Be Food Smart app, which allows you to scan food barcodes to check the salt content.
An Effective Dosing Protocol
It seems likely that maximal zinc absorption, over the long-term, would be provided by a dose somewhere between 40 mg/d and 110 mg/d. We also know that zinc absorption is greater when the dose is spread out, and when it is not accompanied by sources of phytate, such as whole grains, nuts, seeds, and legumes). Therefore, I recommend maximizing zinc absorption as follows:
- Since it takes food about 4-6 hours to move through the stomach and 4-6 hours to move through the small intestine, I’m assuming the short-term saturation of zinc transporters resulting from the presence of zinc in food and supplements would be more or less reset every five hours.
- Aim for a total zinc intake of 40-110 mg/d, split evenly into doses that can be separated by 5 hours.
- Consume zinc supplements away from any meals containing whole grains, nuts, seeds, or legumes, whenever possible.

Prevention Of Diseases Or Conditions Related To Zinc Deficiency
Pregnancy complications and adverse pregnancy outcomes
Estimates based on national food supply indicate that dietary zinc intake is likely inadequate in most low- and middle-income countries, especially those in Sub-Saharan Africa and South Asia . Inadequate zinc status during pregnancy interferes with fetal development, and preterm neonates from zinc-deficient mothers suffer from growth retardation and dermatitis and are at risk of infections, necrotizing enterocolitis, chronic lung disease, and retinopathy of prematurity . Maternal zinc deficiency has also been associated with a number of pregnancy complications and poor outcomes. A recent case-control study conducted in an Iranian hospital reported higher odds of congenital malformations in newborns of mothers with low serum zinc concentrations during the last month of pregnancy . A 2016 review of 64 observational studies found an inverse relationship between maternal zinc status and the severity of preeclampsia, as well as between maternal zinc intake and the risk of low-birth-weight newborns . There were no apparent associations between maternal zinc status and the risk of gestationaldiabetes mellitus and preterm birth. However, the conclusions of this analysis were limited by the fact that most observational studies were conducted in women from populations not at risk for zinc deficiency .

The recommended daily allowance for zinc is 0.8 mg for adults and 0,2 mg per day for children. The RDA for iron is 2 mg. For calcium, the Rda is 3 mg and for magnesium, 2.5 mg . zinc, and iron are the most common minerals in the diet. Zinc is found in foods such as meat, fish, poultry, eggs, nuts, seeds, beans, legumes, dairy products, fruits, vegetables, grains, milk, cheese, bread, pasta, rice, potatoes, cereals, meat substitutes, dried fruits and vegetables and fortified foods. Iron is also found naturally in many foods, including milk and eggs. In addition, iron deficiency is a common problem in developing countries. People with low levels of iron in their bodies are at increased risk of developing certain diseases.
