It is a cofactor for many enzymes and proteins, thus participating in a wide range of biological processes. In humans, zinc is essential for growth, cell division, the immune system, and wound healing.<\/p>\n<p><strong>Health benefits of zinc<\/strong><\/p>\n<p>Zinc is also known for its many health benefits. It is crucial for the proper functioning of the immune system, helping the body fight infections and diseases. In addition, zinc participates in DNA synthesis, promoting cell growth and tissue repair.<\/p>\n<p>Studies suggest that zinc may also play a role in maintaining healthy skin, regulating hormonal function, and even preventing certain chronic diseases.<\/p>\n<p><strong>Prevalence of zinc deficiency<\/strong><\/p>\n<p>Despite its importance, zinc deficiency is a reality for many people around the world. The populations most at risk include those with diets deficient in zinc, pregnant and breastfeeding women, and people with certain chronic diseases.<\/p>\n<p><strong>Symptoms of zinc deficiency<\/strong><\/p>\n<p>Symptoms of zinc deficiency may include:<\/p>\n<ul>\n<li>Delayed growth and development in children.<\/li>\n<li>Decreased immunity, leading to increased susceptibility to infections.<\/li>\n<li>Skin problems, such as rashes and lesions.<\/li>\n<li>Gastrointestinal disorders, such as diarrhea.<\/li>\n<li>Hair loss.<\/li>\n<li>Changes in taste and smell.<\/li>\n<li>Night vision disorders.<\/li>\n<\/ul>\n<p>It is important to note that these symptoms may vary depending on the severity of the zinc deficiency.<\/p>\n<p><strong>Recommended daily amounts<\/strong><\/p>\n<p>The recommended daily amounts of zinc may vary depending on age, gender, pregnancy, breastfeeding, and certain health conditions. Values are generally expressed in milligrams (mg) per day. Here are some general recommendations:<\/p>\n<p><strong>Children:<\/strong><\/p>\n<ul>\n<li>1 to 3 years: 3mg\/day<\/li>\n<li>4 to 8 years: 5mg\/day<\/li>\n<\/ul>\n<p><strong>Adolescents\u00a0:<\/strong><\/p>\n<ul>\n<li>9 to 13 years old: 8mg\/day<\/li>\n<li>14 to 18 years old: 9 to 11mg\/day<\/li>\n<\/ul>\n<p><strong>Adults :<\/strong><\/p>\n<ul>\n<li>Women: 8mg\/day<\/li>\n<li>Men: 11mg\/day<\/li>\n<\/ul>\n<p><strong>Pregnant women:<\/strong> 11 to 12mg\/day<\/p>\n<p><strong>Breastfeeding women:<\/strong> 12 to 13mg\/day<\/p>\n<p>It is important to note that these values are general recommendations and that individual needs may vary. It is always advisable to consult a healthcare professional for personalized nutritional advice.<\/p>\n<p><strong>Best forms of zinc supplements<\/strong><\/p>\n<p>When taking a zinc supplement, it is essential to choose the most appropriate form. Common forms of zinc include zinc sulfate, zinc gluconate, zinc picolinate, and zinc acetate. Each of these forms has a different bioavailability, which can affect how the body absorbs zinc. For example, zinc sulfate is highly soluble in water, and once in water, zinc ions are quickly absorbed by the body. In general, if zinc is in liquid form, and even better in ionic form, it will be easily absorbed and utilized.<\/p>\n<p><strong>Recommended daily amount of zinc supplement<\/strong><\/p>\n<p>The recommended daily amount of zinc may vary depending on individual needs. In general, experts recommend not exceeding a daily dose of 40mg to avoid unwanted side effects. The optimal dose depends on several factors, including age, gender, health status, and the presence of underlying medical conditions. A healthcare professional can assess your individual needs and recommend an appropriate dose based on your specific situation. However, zinc supplements manufactured in Canada will have the generally recommended dosage to meet your needs listed on the label.<\/p>\n<p><strong>Factors that reduce zinc absorption<\/strong><\/p>\n<p>Several factors can reduce zinc absorption in the body. Diets high in phytates, found in certain whole grains and vegetables, as well as excessive fiber intake, can hinder zinc absorption. In addition, certain medical conditions, such as celiac disease and Crohn&#8217;s disease, can also negatively affect the body&#8217;s ability to absorb zinc.<\/p>\n<p><strong>Land Art&#8217;s certified organic ZinC<\/strong><\/p>\n<p>New on the market and made in Quebec, Land Art&#8217;s ZinC is not only certified organic, but also very easy to dose thanks to its graduated dropper. With added vitamin C, Land Art&#8217;s new organic ZinC is perfect for effectively boosting the immune system.

Consulting a healthcare professional can help assess individual needs, identify the best forms of supplements, and determine appropriate amounts to ensure safe and effective zinc supplementation.<\/p>\n<p>References:<\/p>\n<p><a href=\"https:\/\/www.hsph.harvard.edu\/nutritionsource\/zinc\/\">https:\/\/www.hsph.harvard.edu\/nutritionsource\/zinc\/<\/a><\/p>\n<p><a href=\"https:\/\/www.mayoclinic.org\/drugs-supplements-zinc\/art-20366112\">https:\/\/www.mayoclinic.org\/drugs-supplements-zinc\/art-20366112<\/a><\/p>\n<p><a href=\"https:\/\/www.medicalnewstoday.com\/articles\/263176#:~:text=It%20supports%20the%20immune%20function,in%20childhood%20growth%20and%20development\">https:\/\/www.medicalnewstoday.com\/articles\/263176#:~:text=It%20supports%20the%20immune%20function,in%20childhood%20growth%20and%20development<\/a>.<\/p>\n<p><a href=\"https:\/\/webprod.hc-sc.gc.ca\/nhpid-bdipsn\/atReq.do?atid=multi_vitmin_suppl&amp;lang=eng\">https:\/\/webprod.hc-sc.gc.ca\/nhpid-bdipsn\/atReq.do?atid=multi_vitmin_suppl&amp;lang=eng<\/a><\/p>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Zinc, often underestimated, plays a vital role in human biology as a cofactor for many enzymes, contributing to&#8230;<\/p>\n","protected":false},"author":9,"featured_media":4702,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[135],"tags":[],"class_list":["post-4335","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-immunity"],"acf":[],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.1.1 - https:\/\/yoast.com\/product\/yoast-seo-wordpress\/ -->\n<title>Zinc: an essential element for life - Land Art<\/title>\n<meta name=\"description\" content=\"Zinc is unknown to most people.
