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.

What to Look For in Hair, Skin, and Nail Vitamins
The B vitamin is a superstar in the beauty world, offering benefits for both hair, skin, and nails, and is one of the best vitamins to seek out in a beauty supplement, according to Dr. Henry.
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.
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.

Best Overall: Sports Research 5,000 Mcg Biotin Supplements
Biotin is delivered via cold-pressed organic coconut oil to maximize absorption
Vegan formula is free of common allergens and fillers
Not recommended for acne-prone skin types
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.
Type: Softgels | Age Range: Adult 18+ | Dosage: 1 daily | Certified: Non-GMO, allergen-friendly
Best Overall, Runner-Up: Olly Undeniable Beauty Hair, Skin & Nail Gummy
Blends biotin with vitamins C and E and keratin
Gummy formulation is easy to ingest
Contains small amount of sugar
These (very yummy) grapefruit-flavored gummies also contain a good amount of biotin, as well as super important vitamins C and E, powerful antioxidants that do great things. There’s keratin in the mix too, a protein that makes up much of our hair and nails, and Dr. Henry says is a good option to take orally. Plus, can we talk about the crazy affordable price?
Type: Gummies | Age Range: Adults 18+ | Dosage: 2 daily | Certified: B corporation, gluten-free
Best Multivitamin: Ritual Essential for Women
Great option for improving overall health
Clinically studied for efficacy
Subscription-based model ensures you never run out
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
Adaptogens reduce stress-induced inflammation
Saw palmetto blocks DHT to prevent hair loss
Supports overall wellness for better sleep, energy, and mood
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

Blended at a cGMP certified lab to ensure purity and safety
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
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
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
High-potency biotin thickens and smoothes nails
Multiple studies back up product claims
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

Type: Gummies | Age Range: Adult 18+ | Dosage: 2 daily | Certified: Vegan, non-GMO, allergen-friendly
Best With Collagen: Vital Proteins Vitality Immune Booster
Collagen boosts skin elasticity
Zinc, vitamin C, and glutamine provide antioxidant support and boost immune system
Electrolytes boost hydration
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.

Best Probiotic: Garden of Life Dr. Formulated Probiotics For Women
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
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
Contains marine algae-derived omega-3 fatty acids for healthy hair, skin, and nails
Good for overall health
Softgel pills are easy to swallow
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
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.
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.
