If you’ve ever found yourself scanning shelves or scrolling online wondering which magic pill might bring your hair, skin, and nails back to life, you’re not alone. According to the latest research, the use of hair, skin, and nail supplements has nearly doubled in recent years, mirroring the booming beauty supplement market, which is projected to hit $6.8 billion by 2024.


The good news is that some vitamins and supplements might help prevent or slow thinning hair, brittle nails, and dull skin. These products often contain ingredients like biotin, collagen, and antioxidants, which may help promote strength, elasticity, and overall health.

 While they may not be a magic fix, some of the best hair, skin, and nail vitamins and supplements can help support healthier-looking hair, stronger nails, and more vibrant skin.

Choosing the right product, however, can feel overwhelming because there are so many options promising amazing results. That’s why we’ve researched more than 20 hair, skin, and nail vitamins and supplements, evaluated their ingredients, and consulted with three registered dietitians — Melissa Mitri, RD, Andrea Ballenthin, LDN, and Sydney Lappe, RD — to ensure that our picks are effective and safe. Here is our list of the seven best hair, skin, and nail vitamins and supplements, to help you find the right option for your beauty and wellness goals.

Our Top Picks for the Best Hair, Skin, and Nails Vitamins and Supplements

When to Consult Your Doctor

You should speak with your doctor if you’re experiencing significant hair loss, persistent acne or rashes, brittle or discolored nails, or any other unusual changes to your hair, skin, or nails. Underlying health issues like hormonal imbalances, nutrient deficiencies, or autoimmune conditions might be at play, and your doctor can help identify the root cause. They can also recommend the most effective approach, whether that’s a supplement, dietary changes, or other treatments.

Before starting any new supplement, including those for hair, skin, and nails, it’s always best to check in with your doctor. While these supplements can be helpful for some people, they may not be necessary or suitable for everyone. Your doctor can help guide you to the right products based on your unique health needs.

Best Multivitamin

MegaFood Skin, Nails & Hair 2

$25.99 at Amazon
Buy on Amazon $25.99

Pros

  • Provides a variety of nutrients shown to support skin, nails, and hair
  • Made from whole foods
  • Gluten-free, non-GMO, vegan
  • Third-party tested

Cons

  • Users report tablets are large and may be difficult for some to swallow
  • Some users report an unpleasant taste, as the tablets are not coated
  • Best for: Multivitamin
  • Form: Tablets
  • Dose: Two per day
  • Noteworthy ingredients: Vitamin A, vitamin C, biotin, zinc
  • Price: $24.69 per month
MegaFood Skin, Nails & Hair 2 landed on our list for its well-rounded formula packed with vitamins and minerals that support hair, skin, and nail health. This supplement includes key nutrients like vitamins A and C, along with biotin and zinc, all of which are backed by research for their role in promoting stronger nails, healthier hair, and glowing skin.


Research has found that getting enough vitamin A is important for maintaining healthy skin and hair.

 Additionally, vitamin C is a powerful antioxidant that protects skin cells from damage caused by free radicals and also supports collagen production, which is important for firm skin and strong nails. Free radicals are unstable molecules that can harm your skin and hair by causing cell damage.


While more research is needed, some studies suggest that taking a biotin supplement every day may help improve nail firmness, hardness, and thickness.

 Furthermore, zinc appears to play an important role in skin health, as zinc supplementation may help manage skin conditions like dermatitis and acne.


We appreciate that MegaFood’s formula is non-GMO (contains no genetically modified organisms), vegan, and gluten-free, making it a great option for a variety of dietary preferences and restrictions. We also love that MegaFood prioritizes transparency by undergoing third-party testing, ensuring that the product is free from contaminants and contains exactly what’s on the label.

It’s worth noting that some users find the tablets large and hard to swallow, while others mention an unpleasant taste (because the tablets aren’t coated). However, MegaFood Skin, Nails & Hair 2 is a trustworthy and nutrient-packed choice if you’re looking to enhance your beauty routine from the inside out.

Best Biotin

Jarrow Formulas Biotin

$36.56 at Amazon
Buy on Amazon $36.56

Pros

  • Provides a large dose of biotin
  • Budget-friendly
  • Third-party tested
  • Gluten-free, vegan

Cons

  • Only one ingredient
  • Excessive biotin intake may interfere with certain lab tests 
  • Best for: Biotin
  • Form: Capsules
  • Dose: One per day
  • Noteworthy ingredients: Biotin
  • Price: $4.50 per month
Jarrow Formulas Biotin stands out as one of the best supplements for hair, skin, and nails due to its powerful dose of 5,000 micrograms (mcg) of biotin, which provides a whopping 16,000 percent of the recommended daily intake, as your body only needs 30 mcg per day.

 While more research is needed on the effectiveness of biotin supplementation for nail health, some studies have found that it may improve nail thickness and firmness in those with brittle nails. 

The downside to this supplement only containing biotin is that it doesn't offer a broader range of nutrients for overall hair, skin, and nail support. Also, taking too much biotin can interfere with certain lab tests, including those for thyroid and heart function.

 Therefore, it is important to talk with your health care provider before taking high doses of biotin, especially if you’re due for medical testing, to avoid any potential interference with your results.

We appreciate that Jarrow Formulas Biotin is third-party tested to ensure that it meets rigorous quality and safety standards. Additionally, the product is gluten-free, vegan, and free from peanuts or tree nuts, making it a great option for people with those allergies or dietary restrictions.

Best Collagen

Vital Proteins Collagen Peptides Advanced

$42.99 at Amazon
$51Now 16% Off
Buy on Amazon $42.99

Pros

  • Provides collagen to support hair, skin, and nail health
  • Formulated with vitamin C to enhance collagen production
  • Contains hyaluronic acid to promote skin hydration
  • Made without gluten, dairy, or sugar
  • Third-party tested

Cons

  • Not suitable for vegetarians or vegans
  • Product may not mix well in cold drinks
  • Best for: Collagen
  • Form: Powder
  • Dose: 4 tablespoons per day
  • Noteworthy ingredients: Collagen peptides, vitamin C, hyaluronic acid
  • Price: $44.64 per month

Vital Proteins Collagen Peptides Advanced powder combines high-quality ingredients that support overall beauty and wellness. “Vital Proteins Collagen is a high-quality collagen powder I often recommend to clients,” says Mitri. “It contains 20 grams of collagen and 18 grams of protein per serving, a higher amount than most other products.”

Collagen is a protein that is essential for maintaining the structure and elasticity of your skin, as well as the strength of your hair and nails. Studies show that collagen supplementation may help improve skin hydration, elasticity, and density while also promoting stronger hair and nails over time.

 Vital Proteins Collagen Peptides Advanced is also formulated with vitamin C, which enhances collagen production, and hyaluronic acid, which helps retain moisture in your skin, keeping it plump and healthy-looking.

We also love that Vital Proteins Collagen Peptides Advanced is made without gluten, dairy, or sugar, making it a great choice for people with those dietary restrictions. Additionally, “Vital Proteins is a reputable brand in the supplement industry, and many of their products are NSF Certified for Sport, a respected third-party certification that ensures products are held to the highest standards and are free from banned substances,” says Mitri.

Keep in mind that this collagen powder isn’t suitable for vegetarians or vegans because it is sourced from cows. Additionally, our research has found that it doesn’t always mix well in cold drinks, so you might want to blend it in warm beverages for a smoother texture.

Best for Hair Growth

Nutrafol Women’s Balance

$88 at Amazon
Buy on Amazon $88

Pros

  • Provides a variety of nutrients to support hair growth
  • Provides compounds to support balanced hormone levels
  • Non-GMO, gluten-free, and dairy-free
  • Formula is backed by clinical research
  • Third-party tested

Cons

  • May interact with certain medications
  • More expensive than other vitamins and supplements on our list
  • May interfere with lab testing
  • Best for: Hair growth
  • Form: Capsules
  • Dose: Four capsules per day
  • Noteworthy ingredients: Vitamin A, vitamin C, biotin, zinc, maca, saw palmetto
  • Price: $83.60 per month
Nutrafol Women’s Balance has been clinically tested to support hair growth for women. Hair thinning and loss are common concerns for women as they age, often due to hormonal changes. The product has been specifically designed for women 45 and older and includes hormone-supporting ingredients like maca, which may help balance hormonal shifts and prevent hair thinning during perimenopause and menopause.

 The supplement also provides a comprehensive range of hair-supporting nutrients, including vitamin A, vitamin C, biotin, and zinc, making it a well-rounded option for improving overall hair health.

What really sets Nutrafol apart from competitors is its science-backed approach. A six-month clinical trial found that menopausal women taking Nutrafol Women’s Balance daily saw more baby hairs, longer and thicker hair, and less shedding than those taking a placebo.


“As a functional nutritionist specializing in skin, hormone, and gut health, I recommend Nutrafol to help restore balance to the body by providing essential nutrients in one product to support healthy hair, skin, and nails,” explains Ballenthin. She adds that “while Nutrafol is a promising option for many, it’s important to consult with a healthcare provider, as it may not be suitable for everyone, due to potential interactions with medications or underlying conditions.” For example, Nutrafol contains saw palmetto, which may interact with anticoagulants or blood thinners, potentially increasing the risk of bleeding.


Nutrafol Women’s Balance is non-GMO, gluten-free, and dairy-free, as well as third-party tested, meaning it has been independently verified for quality, purity, and safety. However, it’s worth noting that this supplement is pricier than many other hair, skin, and nail supplements, which might not fit everyone’s budget. Additionally, Nutrafol contains high amounts of biotin, which may interfere with lab tests, including those measuring thyroid and heart function.

Best Budget

Nature Made Hair, Skin, Nails

$18.29 at Amazon
$19.29Now 5% Off
Buy on Amazon $18.29

Pros

  • Budget-friendly
  • Provides a variety of nutrients shown to support hair, skin, and nail health
  • Third-party tested
  • Gluten-free

Cons

  • Not suitable for vegans or vegetarians
  • May interfere with lab testing
  • Best for: Budget
  • Form: Softgels
  • Dose: One softgel per day
  • Noteworthy ingredients: Vitamin A, vitamin C, biotin, zinc
  • Price: $4.26 per month
Nature Made Hair, Skin, Nails is our pick for the best budget-friendly supplement for those looking to support their beauty routine without breaking the bank. At only $4.26 per month, it includes a nice blend of nutrients, including vitamin A, vitamin C, biotin, and zinc, all of which may help maintain healthy hair, glowing skin, and strong nails.

For example, biotin is well-known for supporting keratin production, a key protein in hair and nails.

 And zinc, vitamin A, and vitamin C are important for collagen formation and overall skin health.

 This supplement delivers these beauty-enhancing nutrients in an affordable way, making it a perfect option if you’re a budget-conscious beauty enthusiast.
We love that Nature Made is USP Verified, which guarantees that the product is tested for quality, potency, and purity. That means you can be sure that what’s on the label is what’s in the bottle — no surprises. We also appreciate that it’s gluten-free. However, since it contains gelatin, it’s not suitable for vegans or vegetarians. Also, be aware that high doses of biotin, like those in this supplement, may interfere with lab tests, including those for thyroid and heart functioning, potentially leading to inaccurate results.

Best Gummy

Olly Undeniable Beauty Healthy Hair, Skin & Nails

$12.88 at Amazon
$13.99Now 8% Off
Buy on Amazon $12.88

Pros

  • Provides a variety of nutrients shown to support hair, skin, and nail health
  • No artificial coloring or dyes
  • Gluten-free
  • Third-party tested

Cons

  • Not suitable for vegetarians or vegans
  • May interfere with lab testing
  • Best for: Gummy
  • Form: Gummy
  • Dose: Two gummies per day
  • Noteworthy ingredients: Biotin, vitamin C, keratin
  • Price: $12.24 per month

Olly Undeniable Beauty is our favorite gummy vitamin for hair, skin, and nails, thanks to its thoughtfully chosen ingredients, which include biotin, vitamin C, and keratin. Not to mention, they’re delicious and only contain 2 grams of sugar per serving.

“What sets Olly apart from other supplements is the inclusion of keratin,” explains Lappe.

 “Keratin is a protein naturally produced by the body and widely used in beauty products. Each serving provides 50 milligrams of keratin, and while research on keratin is limited and the dosage may be modest for significant effects on its own, combining the nutrients in Olly with a balanced lifestyle may help enhance your beauty routine.”

Olly Undeniable Beauty’s simple ingredient profile is also worth highlighting. The colors come from natural fruit and vegetable juices instead of synthetic dyes. Plus, it’s gluten-free and certified by NSF, a third-party testing organization that ensures the product contains what it claims and is free from harmful contaminants.

This supplement does contain gelatin and isn’t suitable for vegetarians or vegans. Also, it contains high doses of biotin, which can interfere with certain lab tests and might lead to inaccurate results.

Best Omega-3

Nordic Naturals Ultimate Omega

$53.99 at Amazon
$75.95Now 29% Off
Buy on Amazon $53.99

Pros

  • Provides omega-3s, which have been shown to support skin and hair health
  • Non-GMO, free from artificial colors and flavors
  • Gluten-free
  • Third-party tested
  • Pleasant lemon flavor to reduce fishy aftertaste

Cons

  • Not suitable for vegans, vegetarians, or those with fish allergies
  • Doesn’t offer a broader range of nutrients
  • Best for: Omega-3
  • Form: Softgels
  • Dose: Two softgels per day
  • Noteworthy ingredients: Omega-3 (EPA/DHA)
  • Price: $18.51 per month

Omega-3s might not be the first thing you think of for hair and skin health, but they play an important role in maintaining a glowing complexion and strong, healthy hair. That’s why we added Nordic Naturals Ultimate Omega to our list of the best hair, skin, and nails vitamins and supplements.

Research suggests that omega-3 fatty acids help protect the skin from the sun’s damaging ultraviolet rays and may also help reduce inflammation associated with various skin conditions, including dermatitis and acne.

 For hair, omega-3s may nourish hair follicles and help promote hair growth.


Yet, many people aren’t meeting the daily recommended amounts of omega-3, which could impact both your hair and skin — and even overall health.

 These essential fats help prevent disease and support wellness, making them a must-have for your health and beauty routine.

We like that the formula uses non-GMO, gluten-free, and dairy-free ingredients without artificial colors, flavors, or preservatives. Furthermore, Nordic Naturals is third-party tested to ensure that it’s free of harmful heavy metals like mercury, which are often found in fish.

One downside is that the product contains fish oil, so it’s not suitable for vegans, vegetarians, and those with fish allergies. Also, it only contains omega-3s, so it doesn't offer a broader range of nutrients that could support overall hair, skin, and nail health.

How We Reviewed the Best Hair, Skin, and Nails Vitamins and Supplements

When reviewing the best hair, skin, and nail vitamins and supplements, we wanted to make sure we were giving you the most reliable, in-depth advice. To do so, we analyzed a variety of products to see if they were effective, safe, and actually worth your money. We looked at everything from ingredient quality and amounts to whether the products were third-party tested, ensuring that they meet high standards for safety and efficacy. We also consulted with three experienced registered dietitians — Melissa Mitri, RD, Andrea Ballenthin, LDN, and Syndey Lappe, RD — to get their expert take on how these products may help support hair, skin, and nail health.

As a seasoned dietitian, I’ve worked with many people who are looking to improve their health with the right supplements, so I know firsthand how important it is to choose high-quality, science-backed products. My expertise in nutrition and supplement evaluation helped guide this review, making sure that every recommendation comes from a place of professional knowledge and trustworthiness.

What to Look for When Buying the Best Hair, Skin, and Nails Vitamins and Supplements

When shopping for the best hair, skin, and nail vitamins and supplements, it’s important to make sure you’re choosing a product that truly supports your beauty and health goals. The quality of supplements varies, so here are a few key factors to keep in mind when making your decision:

  • Nutrient variety: Look for a supplement with a range of vitamins and minerals, such as vitamin C, vitamin A, zinc, and omega-3 fatty acids.

     These nutrients are backed by science and may help maintain healthy hair, skin, and nails.

  • Third-party testing: Choose products that have been third-party tested for purity and potency to guarantee that they contain what is indicated on the label.
  • Allergen-free: If you have dietary restrictions, make sure the product is gluten-free, dairy-free, or vegan, depending on your needs.
  • Potential contraindications: Certain nutrients may interact with medications or testing results. Always talk with your healthcare provider before adding a supplement to your routine.
  • Brand reputation: Choose brands with a good track record of transparency about their sourcing and manufacturing processes.

Why Do People Use Hair, Skin, and Nail Vitamins?

People use hair, skin, and nail vitamins to support their overall health, improve appearance, and address specific concerns like thinning, brittleness, or dullness. Many of these supplements contain a combination of nutrients like biotin, collagen, vitamin C, vitamin A, zinc, and omega-3s, all of which may help maintain the health of your hair, skin, and nails.

For example, while more robust research is needed, biotin, a B vitamin, may help promote hair strength and growth for people who are deficient in the nutrient.

 Collagen may help improve skin hydration, elasticity, and density, while vitamin C helps protect skin cells from damage caused by free radicals and supports collagen production.

Zinc is another important mineral that may help support skin healing and may prevent hair loss related to deficiencies,

 while omega-3s have been shown to help protect your skin from the sun’s damaging ultraviolet rays, reduce skin inflammation, and help promote hair growth.


Are Hair, Skin, and Nail Vitamins Safe?

Hair, skin, and nail vitamins and supplements are generally safe for most people when taken as directed. However, these vitamins and supplements often provide high doses of certain nutrients that could interfere with certain medications and lab testing results.

For example, saw palmetto is found in some hair, skin, and nail supplements and could interact with anticoagulants or blood thinners, potentially increasing the risk of bleeding.


Additionally, taking high doses of biotin could impact certain lab results, including thyroid and heart function tests, potentially skewing the findings.

It is important to exercise caution and consult with your healthcare provider before starting any new supplement regimen.

What Is the Best Supplement to Grow Hair and Nails?

The best supplement for promoting hair and nail growth often contains a combination of key vitamins and minerals that support cell health and regeneration. For example, biotin, collagen, vitamin C, vitamin A, zinc, and omega-3s have been shown in studies to support hair, skin, and nail health, which could result in shinier hair, clearer skin, and more resilient nails.

Additionally, collagen is an important protein needed for maintaining the structure and elasticity of your skin. Studies show that collagen supplementation may help improve skin hydration, elasticity, and density, while also promoting stronger hair and nails over time.

You should always consult with your healthcare provider before taking any supplements to ensure that they are safe and appropriate for your specific health needs and conditions.

FAQs

Do hair, skin, and nail vitamins actually work?
Hair, skin, and nail vitamins can work, especially if you are deficient in key nutrients like biotin, which may help support healthy hair growth, strong nails, and glowing skin. However, they’re not a quick fix, as results will take time, and they’re most effective when paired with a balanced diet and healthy lifestyle.

Hair, skin, and nail vitamins usually take about two to three months to show noticeable results, as it takes time for new hair and nail growth to appear (in fact, it can take up to six months). Consistency is key, and improvements may depend on factors like your overall diet, health, and whether you had any nutrient deficiencies to begin with.

Hair, skin, and nail vitamins may support hair growth if you’re deficient in certain nutrients, but they’re not a magic solution and results will vary from person to person. Healthy hair, skin, and nails will also depend on a balanced diet and good hygiene practices.
