There’s good reason why they say, “beauty comes from the inside out.” Along with using the right topical products, getting the right nutrients internally can go a long way in your quest for glowing skin, long hair, and strong nails. While in an ideal world, these would come solely from a squeaky clean diet full of fruits and veggies, getting an adequate amount of the vitamins and minerals you need from diet alone simply isn’t realistic for most people. (Because, you know, real life.) 

Enter beauty supplements that work to, well, supplement your diet and can have positive effects on your hair, skin, and nails. The right one can help protect skin from signs of aging, make your nails less likely to chip and break, and leave your hair stronger and less prone to breakage, explains dermatologist Dr. Michelle Henry.

Biotin

Omega-3 Fatty Acids

Another multi-tasking standout, this family of fatty acids gives you plenty of bang for your buck, again having a positive impact on the health of hair, skin, and nails, says Welsh. 

Non-GMO

Dr. Henry says this is an important thing to seek out in any type of supplement. It's a way to ensure you’re getting the highest quality ingredients possible.

According to Dr. Henry, biotin is one of the best ingredients to seek out in a beauty supplement: “It’s fundamental for the health of hair, skin, and nails,” she says. There’s no shortage of biotin options out there, but she’s partial to this pick; the biotin is delivered via cold-pressed organic coconut oil to help improve absorption.

It’s also non-GMO, another attribute Dr. Henry says is important to look for in any supplement. This is an overall fan favorite, consistently pulling in rave reviews and even impressive before and after photos where users share hair and nail growth.

Best Multivitamin: Ritual Essential for Women

ritual
What We Like
  • Great option for improving overall health

  • Clinically studied for efficacy

  • Subscription-based model ensures you never run out

What We Don't Like
  • Slight seaweed smell/taste

Byrdie Commerce Editorial Director Jessica Mahgerefteh raves about this multivitamin (as well as the prenatal version, which she’s currently taking). The specially created and clinically studied formula includes nine nutrients essential for healthy skin, hair, and nails. Among them: Folate, vitamins B12, D3, E, and K2, and omega-3 fatty acids, to name a few.

Along with their beauty benefits—Byrdie Senior Editor Hallie Gould also vouches for their effectiveness and says they improved nail growth— this is also a choice supplement for overall health, helping to boost immunity, bone strength, and more. Bonus points for the convenient subscription model, which ensures you never run out.

Type: Capsules | Age Range: Adult 18-49 | Dosage: 2 daily | Certified: Vegan, allergen-free

Best for Hair: Nutrafol Women Hair Growth Supplement

Nutrafol Women Hair Growth Supplement
What We Like
  • Adaptogens reduce stress-induced inflammation

  • Saw palmetto blocks DHT to prevent hair loss

  • Supports overall wellness for better sleep, energy, and mood

What We Don't Like
  • Very expensive

Both Dr. Henry and Byrdie Email Editor Karli Bendlin recommend this option if you’re dealing with thinning, weak, or otherwise ‘meh’ hair. There are over 21 ingredients in the formula, including adaptogens to help reduce stress-induced inflammation and saw palmetto which helps block DHT (a hormone thought to contribute to hair loss), says Dr. Henry.

It is a bit pricey, and you do have to take four pills daily for up to six months to see results, but those results are legit; in a brand-backed clinical study, 86% of women reported improved hair growth after six months.

Type: Capsules | Age Range: Adult 18-44 | Dosage: 4 daily | Certified: Vegetarian, drug-free, hormone-free

Best for Hair, Runner-Up: Eu Natural 5000 Mcg Biotin Supplement

What We Like
  • Contains potent dose of biotin

  • Speeds up hair growth and boosts shine and fullness

  • Blended at a cGMP certified lab to ensure purity and safety

What We Don't Like
  • Formula contains fillers but claims not to

Another one of Dr. Henry’s picks, she says this is a choice for healthy hair growth. Along with the powerful dose of biotin, she also likes that it’s vegetarian and formulated at a cGMP certified lab to ensure purity and safety. Customers can't stop raving about it, noting that it restores shine, speed up growth, and leaves hair fuller.

Type: Capsules | Age Range: Adult 18+ | Dosage: 1 daily | Certified: Vegetarian, gluten-free, GMP

Best for Skin: Thorne Research Zinc Picolinate 15mg

Thorne Zinc Picolinate 15mg
What We Like
  • Zinc has been studied to be effective at improving acne-prone skin

  • Provides immune support

  • Features antioxidant and anti-inflammatory benefits for the whole body

What We Don't Like
  • May cause stomach discomfort

According to Suzie Welsh, RN, MSN, and founder of Binto, zinc is a top nutrient to seek out for skin purposes. (It’s been well-studied as both a topical and systemic treatment in dermatology and can be a particularly good option for those with acne-prone skin.)

Credit its ability to moderate the body’s inflammatory response, as well as its antioxidant properties that help combat oxidative stress that damages cells throughout the body, not just in the skin. This supplement in particular is a good pick since it uses a highly absorbable (read: effective) form of the nutrient.

Type: Capsules | Age Range: Adult 18+ | Dosage: 1 daily | Certified: Gluten-free, soy-free, dairy-free

Best for Nails: HUM Nutrition Killer Nails Supplements

HUM Nutrition Killer Nails™ Supplements
What We Like
  • High-potency biotin thickens and smoothes nails

  • Multiple studies back up product claims

  • Tasteless capsule

What We Don't Like
  • Results take time

If your tips need a little TLC, consider adding this supplement to your daily routine. The vegan capsule is biotin-based, and a clinical study was shown to help boost nail thickness, reduce splitting, and make the surface of the nail smoother (none of those annoying ridges). Sephora shoppers back up these claims, happily sharing how well the supplement works.

Type: Capsules | Age Range: Adult 18+ | Dosage: 1 daily | Certified: Vegan, vegetarian, paraben-free, sulfate-free

Best Gummy: Pacifica Hair Nirvana Beauty Gummies

  • Affordable

What We Don't Like

“These contain biotin, along with vitamins C and E, and are vegan and super easy to take. Who doesn’t want a gummy?” says Dr. Henry. They’re also non-GMO, free of allergens such as wheat, soy, and gluten, and are super affordable.

Type: Gummies | Age Range: Adult 18+ | Dosage: 2 daily | Certified: Vegan, non-GMO, allergen-friendly

Best With Collagen: Vital Proteins Vitality Immune Booster

Vital Proteins Vitality Immune Booster
What We Like
  • Collagen boosts skin elasticity

  • Zinc, vitamin C, and glutamine provide antioxidant support and boost immune system

  • Electrolytes boost hydration

What We Don't Like
  • Strong, sweet flavor

Vital Proteins is always one of our favorite brands for anything and everything collagen-related, but we’re especially partial to their latest launch. Each of the (very convenient, travel-friendly powder packs) contains five grams of collagen, a protein that Dr. Henry says may help to improve the elasticity of the skin.

But it doesn’t stop there. This newbie also contains essential ingredients for keeping your immune system strong. (And let’s face it, who doesn’t want a little extra immunity boost these days?) There are also electrolytes in the mix to ensure you stay hydrated, always important for both your looks and your immune system. 

Type: Powder | Age Range: Adult 18+ | Dosage: 1 packet daily | Certified: Sugar-free, gluten-free, soy-free

Best Herbal Formula: Gaia Herbs Hair, Skin & Nail Support

Gaia Herbs Hair
What We Like
  • Nettle leaf extract balances oil production

  • Formulated with anti-aging vitamins

  • Provides antioxidant and anti-inflammatory benefits

What We Don't Like
  • Bottle only contains two-week supply

The herbs in this supplement are all loaded with skin-, hair-, and nail-loving minerals, giving you a serious bang for your buck. The totally vegan formula boasts things such as anti-inflammatory horsetail extract, nettle leaf extract which balances oil production, alfalfa extract rich in anti-aging vitamins, and astaxanthin, an antioxidant.

Type: Capsule | Age Range: Adult 18+ | Dosage: 2 twice daily | Certified: B corporation, vegan, gluten-free, soy-free

Best Probiotic: Garden of Life Dr. Formulated Probiotics For Women

Garden of Life Dr. Formulated Probiotics Once Daily Women's Shelf Stable 30 Capsules
What We Like
  • Boosts immunity and gut and vaginal health in addition to promoting healthy skin

  • Formulated with 16 different probiotic strains and 40 billion CFUs

  • Prebiotic bacteria to boosts overall efficacy

What We Don't Like
  • May cause bloating

You probably already know that taking a probiotic can help to promote gut health, but did you know that there’s growing evidence that gut health and skin health are also very connected? It’s why Welsh says taking a probiotic can be a great way to improve the overall quality of your skin and can be particularly beneficial if you’re dealing with acne.

This particular probiotic is our personal fave. It contains 16 different probiotic strains and 40 billion CFUs (basically a measure of its potency). Along with doing great things for your skin and gut, it also helps boost immunity and vaginal health, and, unlike many other probiotic formulas of equal strength, doesn’t have to be refrigerated. It also contains not only probiotics but also a prebiotic fiber (essential food for the probiotic bacteria) to make it all the more effective, says Welsh.

Type: Capsules | Age Range: Adult 18+ | Dosage: 1 daily | Certified: Non-GMO, gluten-free, soy-free, dairy-free

Best Vegan: Zenwise Health Vegan Omega-3 Supplement

Zenwise health Vegan Omega-3 Supplement
What We Like
  • Contains marine algae-derived omega-3 fatty acids for healthy hair, skin, and nails

  • Good for overall health

  • Softgel pills are easy to swallow

What We Don't Like
  • Slight seaweed smell/taste

Omega-3 fatty acids are amazing for everything, hair, skin, and nails,” says Welsh. The only issue? In the supplement space, these most often come from fish oil, which can be an issue for vegans. Enter this vegan alternative; it sources those nutrients from marine algae rather than fish. Along with the beauty benefits.

Type: Softgels | Age Range: Adult 18+ | Dosage: 2 daily | Certified: Non-GMO, vegan

Final Verdict

Given biotin’s multitasking capabilities, it’s no surprise that the Sports Research 5,000 Mcg Biotin Supplement is a true stand-out, boasting a high concentration of biotin and pairing it with cold-pressed organic coconut oil to enhance absorption. For those who prefer to take their supplements in gummy form, the Olly Undeniable Beauty Hair, Skin, & Nail Gummy and Pacifica Hair Nirvana Beauty Gummies are both great (and yes, delicious) choices. And for an all-around multivitamin that checks all the boxes, check out Ritual Essential for Women, a favorite among Byrdie editors, which also has a convenient, subscription-based model so you never have to worry about running out.

FAQ
  • Do hair, skin, and nail vitamins work?

    According to nutritionist Georgia Forsyth, they can work, but it’s important to reach for formulas that include specific vitamins and minerals. In addition to the above, she recommends looking for products with zinc, vitamins E and C, selenium, vitamin B (in particular, niacin and riboflavin), and collagen. "A combination of these will help you on your way to healthy skin, strong nails, and thick hair."

  • Are hair, skin, and nail vitamins safe?

    The ingredients that collectively make up most hair, skin, and nail supplements aren’t harmful due to each vitamin and mineral being present in a smaller concentration, explains Forsyth. “However, it’s important to be mindful of where your products are sourced,” she says. “Look for reputable brands that come backed by experts in the field.” She also recommends looking out for single-ingredient vitamins in some cases, such as with zinc, in order to be able to monitor exactly how much you’re ingesting.

    Whether a single-ingredient or a multivitamin, she stresses the importance of reading the product instructions thoroughly and checking with a dedicated health professional before integrating any new supplement into your routine.

  • Can you take hair, skin, and nail vitamins with prenatal vitamins?

    When it comes to mixing beauty supplements with prenatal vitamins, it really depends on each product's formula. “It’s best to consult with your healthcare practitioner if you’re expecting or wanting to conceive,” says Forsyth.

  • Can you take hair, skin, and nail vitamins with a multivitamin?

    In the case of mixing them with multivitamins, Forsyth says it's typically safe to take both at the same time. “There generally is no real harm in upping the ante; however, the body is only able to metabolize, store, and absorb so many nutrients at a time,” she says. “An overdosage of a specific vitamin or mineral will not increase your results. Instead, you’ll just flush it out (and it will essentially go to waste).” 

  • How often should you take hair, skin, and nail vitamins?

    When it comes to taking beauty supplements, Forsyth suggests taking them every day for maximum results. “However, if you notice any side effects or your skin is having an adverse reaction, then it may be best to take a break or call it quits,” she says. She also mentions the importance of getting familiar with the label of your chosen supplement. “This will break down specific ingredients, the correct dosage, and how long you’ll need to keep it up until you start to see results,” she says.
