But what about taking vitamins every day to keep split ends at bay? Do hair, skin and nail vitamins work? <\/p>\n<p>From Vitamin A to L-Glutamine, there are hundreds of supplements out there. But no matter your health goal, research is key when choosing a supplement. Since they are not FDA-approved, promised results might be murky or false.<\/p>\n<p>However, that doesn\u2019t mean vitamins are proven useless\u2014certain ones can possibly benefit your hair, skin, and nail health. Let\u2019s dive into how vitamins and supplements could boost your beauty transformation.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Which_Vitamins_Are_Best_for_Hair_Skin_and_Nails\"><\/span>Which Vitamins Are Best for Hair, Skin, and Nails?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>First, let\u2019s discuss the difference between vitamins and supplements.<\/p>\n<p>Vitamins are natural, organic compounds found in foods and living creatures. There are only 13 types, and they are necessary for optimal human health.<\/p>\n<p>Supplements, however, are any compound that people consume for health reasons. This can include vitamins, as well as amino acids, herbs, minerals, and more. <\/p>\n<p>To help you narrow down your research, we\u2019re going to explore both options for potential hair, skin, and nail benefits.<\/p>\n<h4><span class=\"ez-toc-section\" id=\"Vitamins\"><\/span><em>Vitamins<\/em><span class=\"ez-toc-section-end\"><\/span><\/h4>\n<p><img decoding=\"async\" src=\"\/storage\/app\/media\/cropped-images\/Hair%20Image%201-0-0-0-0-1615389257.jpg\" alt=\"\" \/><\/p>\n<p>Vitamins come in two varieties\u2014water-soluble &amp; fat-soluble. Water-soluble vitamins are flushed out of the body via hydration, often needing replenishment. They include:<\/p>\n<ul>\n<li>Vitamin B varieties (B1, B2, B3, B5, B6, B7, B9, B12)<\/li>\n<li>Vitamin C<\/li>\n<\/ul>\n<p>On the flipside, fat-soluble vitamins build up in the liver and fatty tissues, more easily (although rarely), leading to overdose or toxicity. They include:<\/p>\n<ul>\n<li>Vitamin A <\/li>\n<li>Vitamin D<\/li>\n<li>Vitamin E<\/li>\n<li>Vitamin K<\/li>\n<\/ul>\n<p>The average person can reach their essential vitamin needs with food pretty easily. But if you want a little extra support, certain hair supplements and vitamins are known to assist the hair growth and overall health of hair, skin, and nails.<\/p>\n<p>For adding inches to your locks, here are a few vitamins to consider:<\/p>\n<ul>\n<li>\n<p><strong>Biotin (B7)<\/strong> \u2013 Sometimes called biotin, vitamin B7 is the most well-known supplement for hair, skin, and nail health. A Biotin supplement breaks down and uses nutrients from fats and carbs to reinforce hair and nail growth. In one particular study, biotin was \u201cshown to increase nail plate thickness by 25% in patients.\u201d<\/p>\n<\/li>\n<li>\n<p><strong>Vitamin E<\/strong> \u2013 This vitamin is prime for skincare health. As a natural antioxidant, vitamin E can potentially ward off skin aging by preventing elastin and collagen breakdown. This supplement also provides natural immune system support and lowers blood clot risk. <\/p>\n<\/li>\n<li>\n<p><strong>Vitamin A<\/strong> \u2013 Another fat-soluble vitamin, vitamin A is often used for skin health in topical form as retinol products. If low on vitamin A, you may experience problems running from dry skin to acne to hair loss.An additional supplement may add more shine, whether topical or ingested.<\/p>\n<\/li>\n<\/ul>\n<h4><span class=\"ez-toc-section\" id=\"Supplements\"><\/span><em>Supplements<\/em><span class=\"ez-toc-section-end\"><\/span><\/h4>\n<p>Don\u2019t be afraid to go beyond the 13 vitamins. We have some of the best minerals, oils, and other supplements to keep your appearance fresh and glowing.<\/p>\n<p>Here are a few supplement picks for adding thickness and shine to your hair, skin, and nails:<\/p>\n<ul>\n<li>\n<p><strong>Fish Oil<\/strong> \u2013  Fat is the beauty key to moisture and youth. Without it, our skin can look dry, tired-looking, and aged. Outside of fats from foods, consider adding a fish oil supplement to your regimen. The oil\u2019s omega-3 fatty acids are known to lower skin inflammation and promote healthy skin cells. They also boost your overall health, particularly supporting your heart and liver. <\/p>\n<\/li>\n<li>\n<p><strong>Zinc<\/strong> \u2013 An essential mineral, zinc is best known as a cold symptom treatment. But this supplement is also useful for its anti-inflammatory qualities. A 2014 review found that zinc helped \u201creduce the amount of acne-causing bacteria in the skin and treat inflamed acne.\u201d<\/p>\n<\/li>\n<li>\n<p><strong>Collagen<\/strong> \u2013 Think of collagen as a building block for skin, nails, and hair. As we age, we start to lose our collagen, leading to a more wrinkled or withered look. Taking collagen supplements may help slow down the aging process, leading to a more filled and youthful look. <\/p>\n<\/li>\n<\/ul>\n<p>Luckily, there are many compounds now that combine these healthy hair, skin, and nail ingredients.

In extreme cases, yes. Since supplements are not FDA-approved, their dosage and availability is wide open. This can lead to greater misuse and potential toxicity. <\/p>\n<p>However, the average person won\u2019t overdose on vitamin C. With caution, care, and common sense,; you will most likely avoid any sort of health issues with vitamin or supplements.<\/p>\n<p>Let\u2019s go over a few steps to take before starting a supplement routine:<\/p>\n<ul>\n<li>\n<p><strong>Do Your Research<\/strong> \u2013 Step one for any supplement decision: Do. Your. Research. Look up all potential benefits and harms of any supplement that you consider. Check for potential interactions with other drugs or supplements that you may already be taking. And always take your medical background and conditions into account.<\/p>\n<\/li>\n<li>\n<p><strong>Check the Dose<\/strong> \u2013 No matter the supplement, always check the proper dosage. Stick with the daily value amount listed, and adjust for any personal health factors if necessary.<\/p>\n<\/li>\n<li>\n<p><strong>Consider Water-Soluble vs. Fat-Soluble<\/strong> \u2013 As stated above, certain vitamins are more toxicity-prone than others. If taking a fat-soluble vitamin, such as vitamin A or vitamin K, be more cautious with your dosage and frequency.<\/p>\n<\/li>\n<li>\n<p><strong>Consult Your Doctor<\/strong> \u2013 If you want to consider a long-term supplement regimen, it\u2019s best to consult your medical providers. They have the expertise and medical history to provide the best guidance for your personal health.<\/p>\n<\/li>\n<\/ul>\n<h2><span class=\"ez-toc-section\" id=\"Are_Vitamins_the_Cure-All\"><\/span>Are Vitamins the Cure-All?<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>Wouldn\u2019t it be nice if one pill could transform your body?
