Does biotin really strengthen nails, and how long does it take? This article explains <strong>biotin for nails<\/strong> in 6 facts, with practical tips that support it.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"1_What_Do_Studies_Show\"><\/span>1. What Do Studies Show?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The evidence for biotin for nails is somewhat better than for hair, but it relies on small, older studies. In one, participants took 2.5 mg of biotin daily for about 6 months, and nail thickness rose by around 25% in some of them. In another small study most participants reported improvement in brittle nails. There are, however, no large controlled trials to confirm this.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"2_Results_Need_Patience\"><\/span>2. Results Need Patience<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Fingernails grow slowly \u2013 about 3 mm a month \u2013 and take 4 to 6 months to replace completely. So do not expect a change before at least 3 months of regular use, and judge the result on the new nail growing from the base.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"3_Other_Causes_of_Weak_Nails\"><\/span>3.
