Supplement Check shows public information about dietary supplements. It is general information, not medical advice, and it does not say that any supplement treats, cures or prevents anything. Upper limits and daily amounts are the adult values published by the NIH Office of Dietary Supplements. For supplements without official limits (such as creatine, melatonin or ashwagandha), answers give the amounts studies have used and the cautions from NIH, FDA and other cited sources; these are not recommendations. Totals across several supplements assume the most each label suggests per day. Needs differ in pregnancy, for children and teenagers, and with some medicines, so talk to a doctor or pharmacist about your own situation.
Labels come from the NIH Dietary Supplement Label Database and Open Food Facts and can be out of date or differ from the pack in your hand. Halal status comes from the Halal or Not? rulebook and the label as listed: it is information, not a fatwa, and where a source is not stated you should check it with the brand.
Buy links, including links to halal-certified or gelatine-free versions and shop links on supplement answers, are Amazon affiliate links. They are offered alongside the answer, never in place of it: Amazon may pay this service a small commission when you buy, at no extra cost to you. We don't sell anything.
The service is free and provided as it is. To the extent the law allows, we are not liable for decisions made using it. Contact: hello@askmizan.com
