Mercadona, the Spanish chain led by Juan Roig, has begun selling a neutral-flavored exercise supplement in selected locations, placing one of sports nutrition\u2019s best-known powders within reach of everyday shoppers. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The product appears in the chain\u2019s official catalog and is reaching shelves in its wellness and supplement area, although the rollout is not yet chain-wide.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The 7.1-oz. jar has a reported price of \u20ac8 (about $9.20). The claims sound simple enough, but the science calls for a closer look. Creatine can support repeated, brief, high-intensity exercise, but that is not the same as curing fatigue following a<a href=\"https:\/\/okdiario.com\/metabolic\/en\/psychology\/a-psychology-professor-says-the-one-thing-wrecking-your-sleep-is-exercising-three-hours-before-bed-and-there-is-a-reason-your-body-resists-28624\/\"> bad night\u2019s sleep<\/a>.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">What is in the jar<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The product is produced by Ynsadiet, a Madrid-area supplement company. Its label lists creatine monohydrate, creatine phosphate, calcium, and phosphorus, which means it is not a jar of pure creatine monohydrate. One level scoop weighs about 0.15 oz., or 4.2 grams, and contains about 0.11 oz., or 3 grams, of creatine.<\/p>\n\n\n\n<div class=\"gb-element-a00da4e5\">\n<div><div class=\"gb-looper-46613eed\">\n<div class=\"gb-loop-item gb-loop-item-a8390598 post-30220 post type-post status-publish format-standard has-post-thumbnail hentry category-health resize-featured-image\">\n<h3 class=\"gb-text gb-text-24a51617\">Read More: <a href=\"https:\/\/okdiario.com\/metabolic\/en\/health\/an-11-year-old-girl-had-a-stroke-a-reminder-that-children-have-them-too-and-the-warning-sign-parents-miss-is-not-weakness-in-the-arm-30220\/\">An 11-year-old girl had a stroke, a reminder that children have them too, and the warning sign parents miss is not weakness in the arm<\/a><\/h3>\n<\/div>\n<\/div><\/div>\n<\/div>\n\n\n\n<p class=\"wp-block-paragraph\">The powder is mixed into roughly 5 to 7 fluid ounces of water, milk, or other drink. Based on the label figures, a full jar provides close to 48 daily servings. At the converted shelf price, each labeled dose costs about $0.19.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">How creatine works<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Your body naturally produces creatine in the liver, kidneys, and pancreas, while meat and fish supply additional amounts. Most of it is<a href=\"https:\/\/ods.od.nih.gov\/factsheets\/ExerciseAndAthleticPerformance-Consumer\/\" target=\"_blank\" rel=\"noopener\"> stored in skeletal muscle<\/a>, where it helps replenish the quick energy muscles need during short efforts of near-maximum intensity.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">In the gym or on the track, a heavy set of squats, a fast sprint, or repeated jumps is where creatine comes in handy.<a href=\"https:\/\/eur-lex.europa.eu\/legal-content\/EN\/TXT\/HTML\/?uri=CELEX:02012R0432-20240819\" target=\"_blank\" rel=\"noopener\"> European rules<\/a> authorize the statement that \u201ccreatine increases physical performance in successive bursts of short-term, high intensity exercise\u201d when the daily serving size is about 0.11 oz., and the product targets adults doing intense exercise. The wording is specific for a reason.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"1800\" height=\"1013\" src=\"https:\/\/okdiario.com\/metabolic\/en\/wp-content\/uploads\/2026\/08\/creatinine-blood-test-kidney-function.jpg\" alt=\"Blood sample tube labeled creatinine for a laboratory test used to assess kidney function\" class=\"wp-image-30234\" srcset=\"https:\/\/okdiario.com\/metabolic\/en\/wp-content\/uploads\/2026\/08\/creatinine-blood-test-kidney-function.jpg 1800w, https:\/\/okdiario.com\/metabolic\/en\/wp-content\/uploads\/2026\/08\/creatinine-blood-test-kidney-function-300x169.jpg 300w, https:\/\/okdiario.com\/metabolic\/en\/wp-content\/uploads\/2026\/08\/creatinine-blood-test-kidney-function-768x432.jpg 768w, https:\/\/okdiario.com\/metabolic\/en\/wp-content\/uploads\/2026\/08\/creatinine-blood-test-kidney-function-1536x864.jpg 1536w, https:\/\/okdiario.com\/metabolic\/en\/wp-content\/uploads\/2026\/08\/creatinine-blood-test-kidney-function-150x84.jpg 150w\" sizes=\"auto, (max-width: 1800px) 100vw, 1800px\" \/><figcaption class=\"wp-element-caption\"><br>A creatinine blood test measures a waste product in the blood and can help doctors assess kidney function.<\/figcaption><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">Can it reduce fatigue?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">So, can this supermarket powder make someone feel less tired? It may help a person sustain repeated explosive efforts, which results in less<a href=\"https:\/\/okdiario.com\/metabolic\/en\/sports\/a-new-study-says-exercise-rewires-the-brain-and-may-explain-something-that-happens-every-time-you-get-tired-28370\/\"> muscular fatigue<\/a> during training. But the authorized European claim does not indicate creatine treats ordinary physical or mental fatigue.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Research on<a href=\"https:\/\/okdiario.com\/metabolic\/en\/nutrition\/its-not-just-any-protein-timing-the-pre-sleep-protein-hack-promises-more-muscle-and-what-the-studies-actually-show-may-surprise-you-28996\/\"> recovery<\/a> is encouraging in places, but it is not closed science. A 2021 meta-analysis found lower markers of immediate muscle damage after exercise, while an<a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/18076246\/\" target=\"_blank\" rel=\"noopener\"> earlier controlled trial<\/a> found no reduction in muscle damage or faster recovery. <\/p>\n\n\n\n<div class=\"gb-element-dcb2dfba\">\n<div><div class=\"gb-looper-b83181f0\">\n<div class=\"gb-loop-item gb-loop-item-1253a949 post-30212 post type-post status-publish format-standard has-post-thumbnail hentry category-sports resize-featured-image\">\n<h3 class=\"gb-text gb-text-6162a333\">Read More: <a href=\"https:\/\/okdiario.com\/metabolic\/en\/sports\/pau-cubarsi-19-the-people-who-criticise-are-going-through-something-bad-and-need-to-be-heard-and-that-is-why-he-does-not-answer-them-30212\/\">Pau Cubarsi, 19: the people who criticise are going through something bad and need to be heard, and that is why he does not answer them<\/a><\/h3>\n<\/div>\n<\/div><\/div>\n<\/div>\n\n\n\n<p class=\"wp-block-paragraph\">A scoop may help some workout routines, but it cannot negate sleep debt, poor nutrition, or poorly planned training.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Dietitian-nutritionist, author and content creator Julio Basulto has warned about a \u201c<a href=\"https:\/\/www.huffingtonpost.es\/life\/salud\/julio-basulto-nutricionista-llegada-creatina-mercadona-su-principal-riesgo-falsa-sensacion-seguridad-f202607.html\" target=\"_blank\" rel=\"noopener\">false sense of security<\/a>\u201d around supplements. His point is down to earth: sleeping well, training properly, and eating a<a href=\"https:\/\/okdiario.com\/metabolic\/en\/nutrition\/antonio-escribano-a-physician-and-nutrition-expert-once-you-turn-60-you-should-eat-real-food-a-statement-that-debunks-the-obsession-with-supplements-27258\/\"> balanced diet<\/a> still provide most of the benefits.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Why the formula is debated<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The formula begs an obvious price question. Because a 0.15-ounce scoop provides about 0.11 ounce of creatine, roughly 71% of each serving is creatine by weight. Calcium and phosphorus comprise part of the remaining blend.<\/p>\n\n\n\n<div class=\"gb-element-4f6994ce\">\n<div><div class=\"gb-looper-70577233\">\n<div class=\"gb-loop-item gb-loop-item-29d949f0 post-30195 post type-post status-publish format-standard has-post-thumbnail hentry category-health resize-featured-image\">\n<h3 class=\"gb-text gb-text-9c8887ac\">Read More: <a href=\"https:\/\/okdiario.com\/metabolic\/en\/health\/sleeping-too-many-hours-is-tied-to-higher-levels-of-a-protein-linked-to-alzheimers-and-the-range-that-protects-you-is-narrower-than-expected-30195\/\">Sleeping too many hours is tied to higher levels of a protein linked to Alzheimer&#8217;s, and the range that protects you is narrower than expected<\/a><\/h3>\n<\/div>\n<\/div><\/div>\n<\/div>\n\n\n\n<p class=\"wp-block-paragraph\">That does not automatically make the product lower in value. Shoppers need to compare the cost of the actual creatine dose, not just the size of the jar. Still, buyers seeking a single-ingredient powder may prefer a product that lists only creatine monohydrate.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">At the end of the day, the evidence-based selling point is not a promise of instant energy. It is a measured dose for those engaging in repeated, intense exercise. Anyone buying it for the<a href=\"https:\/\/okdiario.com\/metabolic\/en\/nutrition\/when-your-energy-keeps-crashing-by-afternoon-a-simple-b-complex-vitamin-might-be-the-quiet-fix-your-body-has-been-craving-29581\/\"> afternoon slump<\/a> is asking the powder to do something its authorized claim cannot promise.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Safety and who should pause<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The Spanish Agency for Food Safety and Nutrition concluded that a daily amount providing about 3 g. of creatine is acceptable for healthy adults when supplied through common creatine forms. <\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The agency says evidence is lacking for people under 18 and advises against use in those with pre-existing kidney disease. This is a general safety assessment, not a product-specific detail.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Pregnant or breastfeeding women, children, and anyone with an illness should use supplements only when there is a justified reason and appropriate professional guidance. Consumers should follow the label indications, avoid higher doses, and remember that supplements do not replace a balanced diet.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A well-planned supermarket shelf can make creatine look as much a staple as breakfast cereal. It is still a supplement, not a shortcut. Keep it away from children, and do not treat it as a replacement for food, recovery, or medical care.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The official safety report was published in<em> Revista del Comit\u00e9 Cient\u00edfico de la AESAN.<\/em><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Creatine has spread from specialist sports stores into an everyday supermarket item.
