Some pairings can cause digestive upset or make the nutrients less effective.\n<\/p>\n<p id=\"mntl-sc-block_5-0\" class=\"comp mntl-sc-block mntl-sc-block-html\"> For most people, combining creatine and protein powder is perfectly safe and may even enhance nutrient uptake and <a href=\"https:\/\/www.health.com\/the-most-effective-workout-supplement-according-to-experts-11824998\" data-component=\"link\" data-source=\"inlineLink\" data-type=\"internalLink\" data-ordinal=\"1\" rel=\"nofollow noopener\" target=\"_blank\">performance benefits<\/a>.\n<\/p>\n<p id=\"mntl-sc-block_7-0\" class=\"comp mntl-sc-block mntl-sc-block-html\"> But more isn\u2019t necessarily better. \u201cOnce muscle stores are saturated, the body simply excretes the excess,\u201d said <a href=\"https:\/\/larazakaria.com\/about\/\" data-component=\"link\" data-source=\"inlineLink\" data-type=\"externalLink\" data-ordinal=\"1\" rel=\"nofollow noopener\" target=\"_blank\">Lara Zakaria, PharmD, CNS<\/a>, an integrative pharmacist and nutritionist specializing in functional medicine and personalized nutrition. \u201cThat\u2019s why most studies use that range consistently and safely.&#8221;\n<\/p>\n<p id=\"mntl-sc-block_9-0\" class=\"comp mntl-sc-block mntl-sc-block-html\"> Combining more than recommended (3 to 5 grams daily) with protein could cause dehydration, gastrointestinal upset, and even kidney strain in some people. Overall, \u201cCreatine itself is safe and well-studied,\u201d said <a href=\"https:\/\/alexlarsonnutrition.com\/about\" data-component=\"link\" data-source=\"inlineLink\" data-type=\"externalLink\" data-ordinal=\"1\" rel=\"nofollow noopener\" target=\"_blank\">Alex Larson, RDN<\/a>, a registered sports dietitian and founder of Alex Larson Nutrition. \u201cJust stick to the effective dosing.\u201d\n<\/p>\n<p id=\"mntl-sc-block_12-0\" class=\"comp mntl-sc-block mntl-sc-block-html\"> Many pre-workout supplements contain caffeine, which can cause your heart rate and <a href=\"https:\/\/www.health.com\/habits-that-raise-your-blood-pressure-11750888\" data-component=\"link\" data-source=\"inlineLink\" data-type=\"internalLink\" data-ordinal=\"1\" rel=\"nofollow noopener\" target=\"_blank\">blood pressure to spike<\/a>. Certain protein powders and shakes also contain caffeine, which can double your dose.\n<\/p>\n<p id=\"mntl-sc-block_14-0\" class=\"comp mntl-sc-block mntl-sc-block-html\"> When you combine lots of caffeine with a heavy protein shake, it can delay gastric emptying\u2014the process where food exits the stomach\u2014and cause nausea, cramping, or reflux.\n<\/p>\n<p id=\"mntl-sc-block_16-0\" class=\"comp mntl-sc-block mntl-sc-block-html\"> This isn\u2019t necessarily harmful, but it can be uncomfortable. \u201cIt\u2019s less about [supplement] interaction and more about timing and tolerance,\u201d said Zakaria. \u201cProtein shakes digest best when the body isn\u2019t in full sympathetic fight-or-flight mode from caffeine.\u201d\n<\/p>\n<p id=\"mntl-sc-block_19-0\" class=\"comp mntl-sc-block mntl-sc-block-html\"> Amino acid blends, like BCAAs (branched-chain amino acids), are essential nutrients that help build muscle. Most protein powders also naturally contain amino acids, so you don\u2019t necessarily need to add more to the mix.\u00a0\n<\/p>\n<p id=\"mntl-sc-block_21-0\" class=\"comp mntl-sc-block mntl-sc-block-html\"> \u201cIf your protein powder already delivers about 20 to 30 grams per serving, [with BCAAs], there\u2019s no meaningful advantage to stacking [more] BCAAs on top,\u201d said Zakaria, who added that too many additional amino acids could potentially lower tryptophan (an essential amino acid) availability and affect your mood.\n<\/p>\n<p id=\"mntl-sc-block_24-0\" class=\"comp mntl-sc-block mntl-sc-block-html\"> Different protein powders often contain varying amounts of calcium, so you may want to take <a href=\"https:\/\/www.health.com\/supplements-and-drugs-to-avoid-taking-with-zinc-11841859\" data-component=\"link\" data-source=\"inlineLink\" data-type=\"internalLink\" data-ordinal=\"1\" rel=\"nofollow noopener\" target=\"_blank\">iron or zinc supplements<\/a> separately\u2014calcium can compete with iron for absorption, said Larson.\n<\/p>\n<p id=\"mntl-sc-block_26-0\" class=\"comp mntl-sc-block mntl-sc-block-html\"> However, having a protein shake around the same time you take your iron supplement isn\u2019t necessarily harmful, said Zakaria, and the delayed effect is clinically irrelevant for most folks who don\u2019t have an existing iron deficiency.\n<\/p>\n<p id=\"mntl-sc-block_29-0\" class=\"comp mntl-sc-block mntl-sc-block-html\"> Herbal supplements like ginseng and green tea extract often contain hidden stimulants. When those stimulants are combined with caffeine from other sources, like some protein powders or pre-workout supplements, they can elevate your heart rate and put more stress on your digestive system, said Larson.\n<\/p>\n<p id=\"mntl-sc-block_31-0\" class=\"comp mntl-sc-block mntl-sc-block-html\"> Additionally, excess caffeine may make it hard to fall asleep and get the adequate rest and recovery your body needs after a hard workout\u2014which, like protein, is crucial for muscle growth.\n<\/p>\n<p id=\"mntl-sc-block_34-0\" class=\"comp mntl-sc-block mntl-sc-block-html\"> There are still safe and effective ways to maintain your supplement routines while also taking protein powder\u2014and consistency is more important than exact timing.\u00a0\n<\/p>\n<p id=\"mntl-sc-block_36-0\" class=\"comp mntl-sc-block mntl-sc-block-html\"> Supplements like omega-3s, vitamin D, probiotics, carbohydrate powders, electrolytes, and green powders are generally safe to consume with your protein shake and won\u2019t interfere with absorption, said Larson.\n<\/p>\n<p id=\"mntl-sc-block_38-0\" class=\"comp mntl-sc-block mntl-sc-block-html\"> For supplements containing caffeine (pre-workout or herbal supplements) or creatine, be sure to read the label and take the recommended dosage, while spacing them out so you don\u2019t overload your digestive system.\u00a0\n<\/p>\n<p id=\"mntl-sc-block_40-0\" class=\"comp mntl-sc-block mntl-sc-block-html\"> Pay special attention to spacing out iron supplements\u2014instead of combining with your morning protein shake, take them on an empty stomach with vitamin C, then wait two hours before consuming anything that could compete with absorption (calcium, zinc, coffee, or tea).\n<\/p>\n<p id=\"mntl-sc-block_42-0\" class=\"comp mntl-sc-block mntl-sc-block-html\"> It\u2019s also worth noting that protein powders and supplements aren\u2019t regulated in the same way medications are. You can feel more confident in your choices with products that have been third-party tested for purity and safety by programs like NSF\u2019s <a href=\"https:\/\/www.nsf.org\/consumer-resources\/articles\/certified-for-sport-program\" data-component=\"link\" data-source=\"inlineLink\" data-type=\"externalLink\" data-ordinal=\"1\" rel=\"nofollow noopener\" target=\"_blank\">Certified for Sport<\/a> or LGC\u2019s <a href=\"https:\/\/choice.wetestyoutrust.com\" data-component=\"link\" data-source=\"inlineLink\" data-type=\"externalLink\" data-ordinal=\"2\" rel=\"nofollow noopener\" target=\"_blank\">Informed Choice<\/a>. And before you start any new supplements or protein powders, check with your doctor, since those two things can also interact with any medications you may be taking.<\/p>\n","protected":false},"excerpt":{"rendered":"For many people looking to optimize their health, protein powders and nutritional supplements are helpful tools, but the&hellip;\n","protected":false},"author":2,"featured_media":261803,"comment_status":"","ping_status":"","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[45],"tags":[102,6636,56,54,55],"class_list":{"0":"post-261802","1":"post","2":"type-post","3":"status-publish","4":"format-standard","5":"has-post-thumbnail","7":"category-nutrition","8":"tag-health","9":"tag-nutrition","10":"tag-uk","11":"tag-united-kingdom","12":"tag-unitedkingdom"},"_links":{"self":[{"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/posts\/261802","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/comments?post=261802"}],"version-history":[{"count":0,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/posts\/261802\/revisions"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/media\/261803"}],"wp:attachment":[{"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/media?parent=261802"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/categories?post=261802"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.newsbeep.com\/uk\/wp-json\/wp\/v2\/tags?post=261802"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
