Collagen supplementation has been shown to <\/span><a href=\"https:\/\/pmc.ncbi.nlm.nih.gov\/articles\/PMC8824545\/#:~:text=The%20evidence%20from%20the%20reviewed,effects%20of%20its%20oral%20supplements.\" target=\"_blank\" rel=\"noopener\"><span style=\"font-weight: 400;\">ward off wrinkles and dryness<\/span><\/a><span style=\"font-weight: 400;\">.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">&#8220;Collagen is important at any age, but it\u2019s particularly relied upon by older adults and those experiencing changes in various parts of their bodies, like their skin and joints,&#8221; agrees registered dietitian <a href=\"http:\/\/betterthandieting.com\/\" target=\"_blank\" rel=\"noopener\">Bonnie Taub-Dix<\/a>, R.D.N., host of the Media Savvy Podcast.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Not to mention, collagen also plays a meaningful role in supporting healthy digestion and gut function by promoting the integrity and function of the intestinal lining, making it a powerful potential ally for those experiencing issues like leaky gut, Axe adds.<\/span><\/p>\n<h3><b>Collagen Sources\u00a0<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">Collagen comes from animal sources, particularly from the bones, skin, and connective tissues of cattle, fish, chickens, and pigs. Although many modern foods don\u2019t offer much collagen, you will find <\/span><i><span style=\"font-weight: 400;\">some<\/span><\/i><span style=\"font-weight: 400;\"> in fish and chicken. The real jackpot here, though, is <a href=\"https:\/\/www.vitaminshoppe.com\/blog\/ways-to-enjoy-bone-broth\/\" target=\"_blank\" rel=\"noopener\">bone broth<\/a>, which is made by simmering animal parts\u2014namely bones and joints\u2014that naturally contain collagen, according to Axe. He recommends drinking bone broth regularly because of its rich supply of collagen and <a href=\"https:\/\/www.vitaminshoppe.com\/c\/vitamins-supplements\/minerals\" target=\"_blank\" rel=\"noopener\">minerals<\/a>.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">These days, many people obtain collagen through <a href=\"https:\/\/www.vitaminshoppe.com\/c\/natural-beauty-skin\/beauty-supplements\/collagen\" target=\"_blank\" rel=\"noopener\">powdered collagen supplements<\/a>, such as <a href=\"https:\/\/www.vitaminshoppe.com\/c\/natural-beauty-skin\/beauty-supplements\/collagen\" target=\"_blank\" rel=\"noopener\">collagen peptides powders<\/a>.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Also worth noting: <\/span><span style=\"font-weight: 400;\">\u201cSome dermatologists believe that eating foods that are high in the building blocks of collagen, including <a href=\"https:\/\/www.vitaminshoppe.com\/c\/vitamins-supplements\/supplements\/amino-acids\" target=\"_blank\" rel=\"noopener\">amino acids<\/a> like proline and lysine, and minerals like copper, can help improve your skin,\u201d explains Melissa Levin, M.D., clinical instructor at Mount Sinai Icahn School of Medicine and dermatologist at Marmur Medical in New York. Shellfish, nuts, and red and lean meats are all sources of copper; legumes and lean meats are good sources of lysine; and egg whites, meats, cheese, and soy all contain proline.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">While collagen isn&#8217;t found in plant foods, plenty of nutrients found in plant foods support the body\u2019s collagen production, including <a href=\"https:\/\/www.vitaminshoppe.com\/c\/vitamins-supplements\/letter-vitamins\/vitamin-c\" target=\"_blank\" rel=\"noopener\">vitamin C<\/a> and <a href=\"https:\/\/www.vitaminshoppe.com\/c\/vitamins-supplements\/minerals\/zinc\" target=\"_blank\" rel=\"noopener\">zinc<\/a>, so consuming plant foods that provide these\u2014like leafy greens, legumes, berries, and citrus fruit\u2014is definitely a good move, says Taub-Dix. <\/span><span style=\"font-weight: 400;\"><a href=\"https:\/\/www.vitaminshoppe.com\/c\/vitamins-supplements\/letter-vitamins\" target=\"_blank\" rel=\"noopener\">Vitamin A<\/a>, found in sweet potatoes, carrots, and spinach, is another supporter of collagen production, Levin adds.\u00a0<\/span><\/p>\n<h3><b>Supplementing With Collagen<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">\u201cAs we age, we produce less collagen, which results in loss of elasticity and volume, and the onset of wrinkles,\u201d says Levin. Preliminary studies suggest bioactive collagen peptide supplements show promise here. One study published in <\/span><a href=\"https:\/\/www.ncbi.nlm.nih.gov\/pubmed\/24401291\" target=\"_blank\" rel=\"noopener\"><i><span style=\"font-weight: 400;\">Skin Pharmacology and Physiology<\/span><\/i><\/a><span style=\"font-weight: 400;\"> found that 2.5 grams of bioactive collagen peptide daily reduced the appearance of wrinkles around the eyes in women ages 45 to 65 after eight weeks.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Of course, you might also choose to try out a collagen supplement to support your joints\u2014or even your gut health.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">To get the most from collagen supplements, Axe suggests seeking out <a href=\"https:\/\/www.vitaminshoppe.com\/c\/natural-beauty-skin\/beauty-supplements\/collagen\" target=\"_blank\" rel=\"noopener\">hydrolyzed collagen peptides<\/a>, which contain collagen that\u2019s been broken down into smaller units that are easiest to digest and utilize. This is particularly helpful if you struggle with gut issues.\u00a0<\/span><\/p>\n<p><strong>Read More: <a href=\"https:\/\/www.vitaminshoppe.com\/blog\/ways-to-enjoy-bone-broth\/\" target=\"_blank\" rel=\"noopener\">8 Ways To Enjoy Bone Broth\u2014Because It&#8217;s SO Good For You<\/a><\/strong><\/p>\n<p><span style=\"font-weight: 400;\">Collagen powders are easy to incorporate into your daily routine, too. &#8220;Adding collagen powder to your morning coffee or smoothie can kickstart your day with a boost of protein that supports skin, joint, muscle, and gut health,&#8221; Axe says. Since these powders are basically tasteless, they blend well into all sorts of foods and drinks, including oatmeal, yogurt, baked goods, and more.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">How much collagen should you consume?<\/span><span style=\"font-weight: 400;\"> &#8220;The suggested daily intake of collagen varies; generally, doses range anywhere from 2.5 to 15 grams per day,\u201d says Karen Linardakis-Cooney, B.C.H.H.P., C.N., a board-certified holistic health practitioner and nutritionist with <a href=\"https:\/\/www.vitaminshoppe.com\/lp\/nutritionists\" target=\"_blank\" rel=\"noopener\">The Vitamin Shoppe.<\/a>\u00a0<\/span><\/p>\n<h2><strong>Keratin: For Strong, Healthy Hair<\/strong><\/h2>\n<p><span style=\"font-weight: 400;\">Keratin is a protective protein and the key structural material of <\/span><a href=\"https:\/\/link.springer.com\/protocol\/10.1007\/978-1-0716-1574-4_5\" target=\"_blank\" rel=\"noopener\"><span style=\"font-weight: 400;\">the outer layer of human skin<\/span><\/a><span style=\"font-weight: 400;\">, according to Taub-Dix. It&#8217;s also the primary <\/span><a href=\"https:\/\/www.cancer.gov\/publications\/dictionaries\/cancer-terms\/def\/keratin\" target=\"_blank\" rel=\"noopener\"><span style=\"font-weight: 400;\">component of hair and nails<\/span><\/a><span style=\"font-weight: 400;\">. In fact, it\u2019s the protein credited for giving hair its <\/span><a href=\"https:\/\/www.vitaminshoppe.com\/blog\/vegan-collagen-support\/\" target=\"_blank\" rel=\"noopener\"><span style=\"font-weight: 400;\">thickness and strength<\/span><\/a><span style=\"font-weight: 400;\">. Additionally, &#8220;keratin is found on cells in the lining of organs, glands, and other body parts,&#8221; she notes.<\/span><\/p>\n<h3><b>Potential Benefits Of Keratin<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">Keratin\u2019s primary function is to protect and strengthen your hair, skin, and nails against external damage, hence why so many people seek it out in supplement form if they\u2019re not feeling great about the quality or health of these parts, says Taub-Dix. Given its presence internally, it seems to play a protective role for many organs, as well.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">You\u2019re likely most familiar with keratin hair treatments (used to make hair smoother and shinier) offered at many salons, but some research suggests taking keratin (specifically keratin hydrolysate) orally may have beauty benefits. One recent study published in <\/span><a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/39367631\/\" target=\"_blank\" rel=\"noopener\"><i><span style=\"font-weight: 400;\">Journal of Cosmetic Dermatology<\/span><\/i><\/a><span style=\"font-weight: 400;\"> found that women who supplemented with keratin for 90 days experienced positive changes in their complexion, hair, and nails\u2014specifically regarding skin roughness, elasticity, and moisturization, appearance of wrinkles, nail hardness, and hair glossiness.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">While keratin may be worth a try at any age, particularly if your hair, skin, and nails look and feel lackluster, it could be exceptionally helpful as you get older. &#8220;Keratin production declines with age,\u201d notes Taub-Dix. \u201cThis can result in changes in your hair and nails over time.\u201d\u00a0<\/span><\/p>\n<h3><b>Keratin Sources<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">\u201cThe body naturally produces keratin, an effort you can support by eating plenty of high-quality protein,\u201d Taub-Dix says. She recommends prioritizing protein sources such as meat, poultry, eggs, fish, legumes, and beans.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">\u201cYou need enough protein in your diet to produce and maintain your hair&#8217;s strength,&#8221; Axe agrees. He recommends aiming for about 20 to 30 grams of protein per meal to ensure you\u2019re hitting the mark. Otherwise, &#8220;be sure you get enough <a href=\"https:\/\/www.vitaminshoppe.com\/c\/vitamins-supplements\/minerals\/iron\" target=\"_blank\" rel=\"noopener\">iron<\/a>, <a href=\"https:\/\/www.vitaminshoppe.com\/c\/vitamins-supplements\/letter-vitamins\/vitamin-e\" target=\"_blank\" rel=\"noopener\">vitamin E<\/a>, and <a href=\"https:\/\/www.vitaminshoppe.com\/c\/vitamins-supplements\/minerals\" target=\"_blank\" rel=\"noopener\">trace minerals<\/a> like selenium, copper, and magnesium, which also encourage healthy hair,&#8221; he adds.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Of course, if you\u2019re not thrilled with how your skin, hair, or nails look or feel, you can always look for a keratin product to support their strength and resilience, suggest Taub-Dix.<\/span><\/p>\n<h3><b>Supplementing With Keratin<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">If you\u2019re looking to ramp up the keratin in your life, you can take a couple of approaches.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">For those with hair damage from chemical processes or excessive styling, topical keratin treatments can help <\/span><a href=\"https:\/\/www.instyle.com\/healthier-keratin-straightening-treatment-5359230\" target=\"_blank\" rel=\"noopener\"><span style=\"font-weight: 400;\">repair and restore hair\u2019s luster and strength<\/span><\/a><span style=\"font-weight: 400;\">, according to Cooney. For example, keratin-enhanced hair-care products like shampoos, hair masks, and conditioners can help smooth frizz, increase shine, and strengthen hair by filling in porous strands, she says.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Oral supplements containing keratin are also popular options for more widespread benefits. Typically available in capsule and powder form, many of these supplements combine keratin protein with other nutrients like vitamin C, zinc, other <a href=\"https:\/\/www.vitaminshoppe.com\/c\/vitamins-supplements\/antioxidants\" target=\"_blank\" rel=\"noopener\">antioxidants<\/a>, and collagen that <\/span><a href=\"https:\/\/www.health.harvard.edu\/diseases-and-conditions\/vitamins-minerals-and-hair-loss-is-there-a-connection\" target=\"_blank\" rel=\"noopener\"><span style=\"font-weight: 400;\">support healthy hair<\/span><\/a><span style=\"font-weight: 400;\">, Cooney says. There\u2019s no standard dosage here, though <\/span><a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/39367631\/\" target=\"_blank\" rel=\"noopener\"><span style=\"font-weight: 400;\">research<\/span><\/a><span style=\"font-weight: 400;\"> suggests both 500 and 1,000 milligrams of keratin hydrolysate per day is effective.<\/span><\/p>\n<h2><strong>Biotin: The Beauty Vitamin<\/strong><\/h2>\n<p><span style=\"font-weight: 400;\">Also known as <a href=\"https:\/\/www.vitaminshoppe.com\/c\/natural-beauty-skin\/beauty-supplements\/biotin\" target=\"_blank\" rel=\"noopener\">vitamin B7<\/a>, biotin is an essential nutrient that aids in the metabolism of fatty acids, glucose, and amino acids, explains Cooney. \u201cBiotin also helps the body make keratin, contributing to hair strength and promoting hair growth and thickness,\u201d she says.<\/span><\/p>\n<h3><b>Potential Benefits of Biotin<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">Biotin\u2019s role in keratin production makes it a potentially valuable supplement for promoting the strength and growth of hair and nails, according to Taub-Dix. It&#8217;s often recommended for people experiencing hair thinning as it may help support regrowth and follicle strength, she says.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Biotin\u2019s potential hair and nail benefits may also stem from its role in energy production. &#8220;Biotin and other <a href=\"https:\/\/www.vitaminshoppe.com\/c\/natural-beauty-skin\/beauty-supplements\/biotin\" target=\"_blank\" rel=\"noopener\">B vitamins<\/a> are needed to convert the food you eat into usable energy,\u201d says Axe. Your body needs ample energy for every process it performs, maintaining healthy locks and nails, included. Biotin, in particular, is also important for cell growth.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Perhaps unsurprising: Biotin deficiency is often identified by brittle hair and nails, notes Levin.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">It\u2019s worth noting that <\/span><a href=\"https:\/\/pmc.ncbi.nlm.nih.gov\/articles\/PMC11324195\/\" target=\"_blank\" rel=\"noopener\"><span style=\"font-weight: 400;\">study results<\/span><\/a><span style=\"font-weight: 400;\"> on biotin supplementation for hair have been mixed. However, &#8220;Several studies, including one published in <\/span><a href=\"https:\/\/onlinelibrary.wiley.com\/doi\/10.1155\/2015\/841570\" target=\"_blank\" rel=\"noopener\"><i><span style=\"font-weight: 400;\">Dermatology Research and Practice<\/span><\/i><\/a><span style=\"font-weight: 400;\"> and another in the <\/span><a href=\"https:\/\/pmc.ncbi.nlm.nih.gov\/articles\/PMC3509882\/\" target=\"_blank\" rel=\"noopener\"><i><span style=\"font-weight: 400;\">Journal of Clinical and Aesthetic Dermatology<\/span><\/i><\/a><i><span style=\"font-weight: 400;\">,<\/span><\/i><span style=\"font-weight: 400;\"> suggest that supplementing with biotin and increasing intake from your diet can help promote hair growth and fullness in about three to six months,&#8221; shares Axe.\u00a0<\/span><\/p>\n<p><strong>Read More: <a href=\"https:\/\/www.vitaminshoppe.com\/blog\/causes-of-hair-loss-in-women\/\" target=\"_blank\" rel=\"noopener\">The Top Causes Of Hair Loss In Women<\/a><\/strong><\/p>\n<p><span style=\"font-weight: 400;\">Perhaps this vitamin\u2019s biggest claim to fame, though, is supporting healthy nails.

The best way to meet your needs? A varied diet containing lots of whole foods.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Since this vitamin is water-soluble, meaning the body does not store it, you need to regularly replenish it via your eats. Thankfully, that\u2019s pretty easy to do considering biotin is found in a wide variety of foods, including eggs (particularly egg yolks), organ meats, dairy products, nuts, seeds, sweet potatoes, bananas, and leafy green vegetables, Taub-Dix says.\u00a0<\/span><\/p>\n<h3><b>Supplementing With Biotin<\/b><\/h3>\n<p><span style=\"font-weight: 400;\">In addition to eating biotin-containing foods, you can also take the B vitamin as a supplement, most often in capsule form. &#8220;You\u2019ll find biotin in many beauty products and supplements, particularly those geared towards people experiencing thinning hair and brittle nails,&#8221; Taub-Dix says.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\"><a href=\"https:\/\/www.vitaminshoppe.com\/c\/natural-beauty-skin\/beauty-supplements\/biotin\" target=\"_blank\" rel=\"noopener\">Biotin supplements<\/a> typically contain much higher amounts than the RDA. &#8220;Dosages often range from 1,000 to 10,000 micrograms,\u201d shares Axe.\u00a0<\/span><\/p>\n<p><span style=\"font-weight: 400;\">These potent doses aren\u2019t an issue for most people; however, people prone to breakouts might want to be mindful. <\/span><span style=\"font-weight: 400;\">\u201cBoth biotin and pantothenic acid (vitamin B5) are absorbed through the same intestinal receptors,\u201d explains Levin. \u201cIf someone takes an excess amount of biotin, the biotin can saturate these receptors and inhibit B5 absorption. Since B5 plays a role in skin barrier function, hindered absorption may spur worsening breakouts.\u201d<\/span><\/p>\n<h2><strong>The Bottom Line: Should You Take Collagen, Keratin, or Biotin (Or All Three)?<\/strong><\/h2>\n<p><span style=\"font-weight: 400;\">If you&#8217;re looking to improve skin elasticity, gut function, and joint health, collagen may be your best bet. Meanwhile, for those focused on hair and nail health, keratin and biotin supplements can both provide benefits. <\/span><span style=\"font-weight: 400;\">Whichever you choose, all three are low-risk options that can likely help you to look and feel your best.
