While supplements can help close the gap, they don&#8217;t always mix well with others in your routine. Certain nutrients compete with magnesium in the gut, which makes it hard for the body to absorb the magnesium it needs.\n<\/p>\n<p id=\"mntl-sc-block_5-0\" class=\"comp mntl-sc-block mntl-sc-block-html\"> <a href=\"https:\/\/www.health.com\/calcium-8558241\" data-component=\"link\" data-source=\"inlineLink\" data-type=\"internalLink\" data-ordinal=\"1\" rel=\"nofollow noopener\" target=\"_blank\">Calcium<\/a> supplements are commonly taken to improve and maintain bone health, often alongside magnesium.\u00a0\u00a0\n<\/p>\n<p id=\"mntl-sc-block_7-0\" class=\"comp mntl-sc-block mntl-sc-block-html\"> Although it\u2019s <a href=\"https:\/\/www.health.com\/calcium-and-magnesium-8425841\" data-component=\"link\" data-source=\"inlineLink\" data-type=\"internalLink\" data-ordinal=\"1\" rel=\"nofollow noopener\" target=\"_blank\">safe to take them together<\/a>, separating magnesium and calcium supplements may improve the absorption and maximize the benefits of both of these nutrients.\n<\/p>\n<p id=\"mntl-sc-block_9-0\" class=\"comp mntl-sc-block mntl-sc-block-html\"> Calcium and magnesium compete for absorption in the gut. Excess calcium blocks the absorption of magnesium into the cells lining the gut and increases urinary excretion of magnesium.\n<\/p>\n<p id=\"mntl-sc-block_11-0\" class=\"comp mntl-sc-block mntl-sc-block-html\"> \u201cWhen calcium is present in higher concentrations compared to magnesium, the body\u2019s ability to absorb and use magnesium significantly decreases and supplementation is less effective,&#8221; <a href=\"https:\/\/www.connealymd.com\/\" data-component=\"link\" data-source=\"inlineLink\" data-type=\"externalLink\" data-ordinal=\"1\" rel=\"nofollow noopener\" target=\"_blank\">Leigh Erin Connealy<\/a>,\u00a0 integrative and functional medicine doctor and Medical Director at Center for New Medicine, told Health.\u00a0\n<\/p>\n<p id=\"mntl-sc-block_13-0\" class=\"comp mntl-sc-block mntl-sc-block-html\"> To get the most out of your magnesium and calcium supplements, Connealy recommends waiting around two hours between taking magnesium and supplementing with other minerals, like calcium.\n<\/p>\n<p id=\"mntl-sc-block_16-0\" class=\"comp mntl-sc-block mntl-sc-block-html\"> <a href=\"https:\/\/www.health.com\/iron-benefits-7643991\" data-component=\"link\" data-source=\"inlineLink\" data-type=\"internalLink\" data-ordinal=\"1\" rel=\"nofollow noopener\" target=\"_blank\">Iron<\/a> is a mineral that\u2019s necessary for growth, energy production, hormone synthesis, and neurological development.

However, taking either in high doses can decrease the absorption of both minerals, as they compete for absorption in the gut.\n<\/p>\n<p id=\"mntl-sc-block_20-0\" class=\"comp mntl-sc-block mntl-sc-block-html\"> While taking iron and small doses of magnesium usually won\u2019t cause an issue, it\u2019s <a href=\"https:\/\/www.health.com\/can-you-take-iron-and-magnesium-together-11865702\" data-component=\"link\" data-source=\"inlineLink\" data-type=\"internalLink\" data-ordinal=\"1\" rel=\"nofollow noopener\" target=\"_blank\">best to take them separately<\/a>, separated by a few hours, to promote optimal absorption.\u00a0\n<\/p>\n<p id=\"mntl-sc-block_22-0\" class=\"comp mntl-sc-block mntl-sc-block-html\"> Magnesium salts like <a href=\"https:\/\/www.health.com\/magnesium-oxide-8416154\" data-component=\"link\" data-source=\"inlineLink\" data-type=\"internalLink\" data-ordinal=\"1\" rel=\"nofollow noopener\" target=\"_blank\">magnesium oxide<\/a> are more likely to reduce iron absorption.\u00a0They may interfere with iron by raising the <a class=\"recommendation-inline-link\" href=\"https:\/\/www.health.com\/ph-balance-7101062\" data-component=\"link\" data-source=\"inlineLink\" data-type=\"internalLink\" data-ordinal=\"2\" rel=\"noopener noreferrer nofollow\" target=\"_blank\">pH<\/a> in the intestines. Since iron availability depends on an acidic environment, this reduces its absorption. Additionally, some forms of magnesium salts can directly bind to iron, further interfering with its absorption.\n<\/p>\n<p id=\"mntl-sc-block_24-0\" class=\"comp mntl-sc-block mntl-sc-block-html\"> For the most benefits, it\u2019s recommended to take iron separately from other minerals, like magnesium, ideally on an empty stomach.\n<\/p>\n<p id=\"mntl-sc-block_27-0\" class=\"comp mntl-sc-block mntl-sc-block-html\"> Zinc is required for immune function, protein production, skin health, and many other essential processes.
