If you’re looking to refresh your overall look in 2025, investing in the right hair, skin and nail supplements is a smart move. With so many options available, finding the best ones can be overwhelming, but we've found picks that will fit all budgets and tastes.
CNET experts have handpicked the top vitamin supplements for hair, skin and nail health -- making your search stress-free.
What are the best overall vitamins for hair, skin and nails?
There are a lot of multivitamins that claim that they can improve hair, skin and nails, you need to pay attention to the ingredients. The best overall vitamins for hair, skin and nails include vitamin B7 (biotin), collagen, vitamin C and omega-3s.
Vitamin B7 is essential for the health of your hair, skin and nails. It isn't the type of thing you can stock up on -- taking a ton of biotin doesn't amplify the benefits. Collagen is a protein that makes up connective tissue. As we age and our production of collagen decreases, the once-tight fibers become more like a maze. This translates to wrinkles on the face. Supplements that include collagen help your skin elasticity and reduce wrinkles. Vitamin C has various benefits for the body, and it also increases collagen production in your body. Lastly, omega-3s help maintain the cholesterol-derived layer of our skin cells. They contribute to the shine of your hair and keep your scalp healthy. Studies have found that it can also help treat the symptoms of inflammatory skin conditions.
Best vitamins for hair, skin and nails in 2025
Pros
- Affordable multivitamin at around $12 a bottle
- USP certified, meaning the factories meet FDA good manufacturing practices
- Lasts for 50 days
Cons
- The vitamins aren't third-party certified for purity
- Not an option for vegans because they contain gelatin
Nature's Bounty Extra Strength multivitamin is the best overall hair, skin and nail vitamin because of its robust nutrient composition. It's also one of the most affordable multivitamins you can find, at around $10 for a 150-capsule bottle. The dosage is three soft gel capsules each day -- not the worst I've seen, but not the best either.
Vitamin A and zinc are included in this multivitamin to promote collagen production. If you have a vitamin D deficiency, a huge benefit of this is you also get 100% of your daily recommended amount, which may help clear up acne. Unlike other options available, Nature's Bounty multivitamin includes horsetail for thinning hair and skin health. A 2019 review of research found insufficient evidence to establish horsetail as an effective treatment for hair loss.
Nature's Bounty also includes a significant amount of biotin (vitamin B7) at 5,000 mcg per serving. That sounds like a lot, but no side effects have been reported in doses of up to 10,000 mcg (10 mg) of biotin. Experts note that supplementing biotin at high levels can cause false or low test results for immunoassays, which use biotin as part of the testing method. That's something to consider for upcoming doctor's appointments.
Pros
- Products from Olly are third-party tested and are NSF certificated
- Affordable and taste great
- Great for those that don’t like swallowing pills
Cons
- Not suitable for vegans as they contain gelatin
- Each serving contains 2 grams of added sugar
Olly Undeniable Beauty gummy vitamins promote hair, skin and nail health with key ingredients biotin, vitamin C, vitamin E and keratin. Vitamin E has been linked to treating eczema by suppressing inflammation. Vitamin C aids in collagen production and UV skin protection.
Olly Undeniable Beauty Hair, Skin and Nails vitamins contain a large dose of biotin at 2,500 mcg. I was also glad to see 50 mg keratin included in the Olly Undeniable Beauty vitamin. Keratin is the basic component in our hair, skin and nails. The research into the effectiveness of taking additional keratin supplements is lacking, but it's a good option for people with a keratin deficiency.
Olly is naturally flavored and colored with sweet potatoes, apples, cherries, radish, carrot and blueberry juices. Reviews of Olly suggest these grapefruit-flavored gummies taste good. Note that some reviewers say the smell is off-putting in some batches. I like Olly because of the depth of the product line. If you're looking for a vitamin that only targets hair or nail health, you have that option.
Pros
- Third-party tested to ensure there are no heavy metals or chemicals
- Offers a hair wellness quiz that matches you with supplements best suited for you
- Clinically studied
Cons
- More expensive than other options on the list
- Four capsules a day is more than some people may want to manage
Nutrafol Women vitamins support hair growth by focusing on the causes of thinning hair -- like your stress levels and nutrition. They contain medical-grade ingredients, including collagen, maca, astaxanthin and saw palmetto. In addition to vitamin A, vitamin C and vitamin D, you get 3,000 mcg of biotin in this vitamin. Nutrafol has been clinically studied and shown to promote hair regrowth by 80% over time. Nutrafol says results will be noticeable in three to six months.
The thing I like most about Nutrafol is that you don't have just one option; there are several hair supplements to choose from. You can take Nutrafol's hair wellness quiz to find the best fit for you. For instance, if your hair loss is hormonally related, Nutrafol Women's Balance vitamin is the best choice.
Nutrafol hair supplements have the highest vitamin levels on the list, which means they're more expensive for a 120-capsule bottle. With a four-capsule dosage, that's only a 30-day supply. You can opt for monthly delivery subscription through Amazon and knock that price down to $79 per month.
Pros
- United States Pharmacopeia verified
- Great candy-like, berry flavor
- No artificial flavors, dyes, sweeteners or high fructose corn syrup
- One bottle lasts 75 days
Cons
- Gummies are a little tough
- Only contains biotin and vitamin C
If you want a great-tasting gummy vitamin but want to spend a little less than the Olly vitamins above, Nature Made's Hair, Skin and Nails gummies are for you. Compared with other vitamins on Amazon, Nature Made's gummies cost only around $14 for a 75-day supply, making it the most affordable hair, skin and nail vitamin on this list.
Nature Made includes a hefty dose of biotin at 2,500mcg per serving. This is the same amount of biotin found in Olly but at a better cost. A single serving also includes 100mg of vitamin C -- an essential nutrient for boosting collagen production. Additionally, CNET's Caroline Igo, our wellness editor, takes these vitamins every day. She agrees with the many positive reviews that these gummies taste like candy. She loves the mixed berry, cranberry and blueberry flavor.
While these gummies only contain biotin and vitamin C, some prefer their vitamins without any unfamiliar ingredients (e.g., horsetail extract) or other additives. Nature Made gummies are also made without artificial flavors or sweeteners, synthetic dyes or high fructose corn syrup.
Pros
- Free of major allergens like eggs, dairy and shellfish, and they are non-GMO and gluten-free
- You have the opportunity to choose from the various supplements Persona offers
- Persona has a team of nutritionists who are available for free consultations
Cons
- Not third-party tested for purity
- While not the most expensive on this list, still pricey
Persona Nutrition offers some of the best opportunities to personalize hair, skin and nail vitamins. It's a vitamin subscription service, so you don't have to worry about running out. They come in convenient daily packs that will be shipped to your home.
You start by taking Persona's extensive assessment, which asks about your health concerns, allergies, and diet. This helps match your needs with the supplements offered. The hair, skin and nail vitamin from Persona aims to smooth fine lines, hydrate your skin and help your hair and nails grow with a balance of ingredients like collagen, hyaluronic acid and horsetail extract. Persona has one of the highest biotin content on the list at 5 mg or 5,000 mcg.
With Persona, you can create a regiment of supplements that address the vitamins and minerals you are lacking. They offer a ton of options. After I took the assessment I was matched with over five supplements. Always check interactions between supplements and your existing medication before starting. More is not always better for you.
Keep these factors in mind when searching for the best supplements for you.
Ingredients
Always study the ingredients in any vitamin supplement. If you are looking to support healthy hair, skin and skins, look for vitamins that contain biotin, collagen, vitamin C and omega-3s. Speak with your doctor before starting any supplements.
Serving size
You may have to take up to four pills each day, depending on the serving size. Keep this in mind if you dislike swallowing a lot of pills. Also, the serving size directly affects how long a bottle will last you. Even if you have a product with 120 tablets, if you have to take four tablets a day, this will only last you 30 days.
Form
Vitamins and supplements come in either tablets, capsules, gel capsules or gummy form. Depending on your personal preference, you should look for vitamins that fit your needs. For example, if you don’t want extra sugar in your vitamins, don’t buy gummy vitamins. If you don’t like swallowing pills, maybe gummy vitamins are the best option.
Verifications
Dietary supplements aren't regulated by the FDA, but there are a few verifications you can check for that ensure the product you're buying is safe to use.
Those verifications include:
- United States Pharmacopeia: A nonprofit that sets standards for dietary supplements.
- National Sanitation Foundation: This ensures standards set for the facility are met.
- Consumer Lab: Private company tests supplements for accuracy of ingredient identity, content and purity.
- Dietary Supplement Verification: This program ensures any product with a USP-verified label contains accurate, pure ingredients and has been manufactured using Good Manufacturing Practices.
The FDA doesn't regulate vitamins and supplements, which means there are fewer quality regulations for companies to meet. I haven't tested these products in-house; the choices are based on product research for vitamin and mineral ingredients, third-party certifications and consumer reviews.
Several vitamins and nutrients play a part in improving the health and appearance of your hair, skin and nails. Vitamin B7, collagen, vitamin C and omega-3s are all great supplements. Some help directly, in the case of biotin, while others, like vitamin C, help indirectly.
The research on the effectiveness of supplements is limited. Most hair, skin and nail vitamins are loaded with biotin, which is essential to keep your hair shiny and skin moisturized and give you strong nails. If you eat a healthy diet, taking supplements won't make your hair grow faster or thicker. Vitamins balance out deficiencies in the nutrients our bodies naturally produce.
Biotin, which contains Vitamin B, is considered as one of the best vitamins that contribute to hair thickness and growth. Vitamin B deficiencies can lead to hair loss.
There is no known correlation between Vitamin D supplements and weight change. In fact, studies suggest that higher Vitamin D levels can be associated with lower chances of gaining body fat in women.
The way biotin works is by providing a vitamin where people might be deficient. It's more commonly used to prevent hair loss due to this deficiency than it is to actually make hair grow longer. That said, it does not increase the amount of facial hair a female has.
