There are a lot of reasons why guys might want to find the best vitamins for beard growth, but science suggests that one stands out above the rest:
Multiple studies have shown that women like a manly mane.

In fact, one study from the Journal of Evolutionary Biology showed that women were more attracted to men with facial hair than guys who were bare-faced.
But while a man’s motivation to grow his facial hair might be pretty high, everyone’s diet, genetics and body chemistry is a little different.
Some guys struggle to grow the kind of thick, full beard that attracts women and impresses other men, which is where beard growth vitamins and supplements come in.
The best beard growth supplements contain essential vitamins and minerals that help make up for any deficiencies in your daily diet, providing you with the nutrients you need to grow healthy and handsome facial hair.
To help get your facial hair growth going, in this post we’ll break down the best beard vitamins for healthy hair growth, and recommend some of the most effective multivitamins that will help your beard look its best.

A (Quick) Word of Caution
Even though most of the vitamins listed below are essential nutrients that would likely be found in a healthy diet, taking any kind of supplements can involve some degree of risk.
So keep in mind that your safest bet is always to speak with your doctor before ingesting any new pills or tablets.

The (Absolute) Best Vitamins for Beard Growth
Breaking Down the Best Beard Growth Vitamins & Supplements for a Full, Thick & Manly Mane ↓

First Up:
What are the best vitamins for beard growth?
Biotin/B7

Number one with a bullet, biotin, also known as vitamin B7, is one of the most essential nutrients for a thick beard full of healthy hair.
It’s usually found within your body’s enzymes, which help to break down fat and carbs.
But if you have a patchy beard (or some thinning hair loss up top), a biotin deficiency is likely the culprit.
As WebMD put it, “There isn’t a good test for detecting low biotin levels, so it’s usually identified by its symptoms, which include thinning hair,” among others.
Fortunately, Healthline points out that boosting your B7 levels – either through biotin supplements or through food like egg yolk, almonds and bananas – “may assist in regrowth.”
“There’s some research to suggest that increased biotin intake can improve overall hair quality, including thickness and shine.”
Biotin is a water-soluble vitamin, which means your body will likely flush out any excess B7 when you pee, but you don’t need a massive amount of biotin to get a fuller beard.
But as Very Well Health notes, a little can go a long way:
“People who support its use often recommend taking 2 to 5 milligrams (mg) of biotin in supplement form daily in order to strengthen hair and achieve results.”
Vitamin D
In addition to being good for your overall health, Vitamin D, and specifically vitamin D3, play two important roles in promoting beard growth.
First, vitamin D helps balance your hormones, which triggers testosterone production.
Testosterone helps propel hair growth, and there’s a high correlation between a man’s testosterone levels and the amount of hair on his body, so anything you can do to boost your T-levels helps.
Second, vitamin D can also help you form brand new hair follicles, which is exactly what you need to grow a fuller, thicker beard.
Vitamin C
Vitamin C is an antioxidant that not only promotes healthy beard growth, but also helps fortify your immune system.
Vitamin C has been shown to reduce your body’s level of free radicals, which harm hair follicles and may lead to pattern baldness.
Vitamin E
Vitamin E also has antioxidant properties that can help repair hair follicles.
But it has the added bonus of also promoting blood circulation, which helps with skin health.
In addition to healthy skin, vitamin E helps promote healthy facial hair by making it more moisturized, giving your beard a healthy and appealing shine.
Niacin/B3

Also called vitamin B3, niacin contributes to the production of various hormones within your body.
Male hormone levels play a key role in hair loss, and beard supplements like niacin can help ensure that you have the right balance.
Plus it helps with blood flow, which contributes to healthier hair follicles.
Horsetail Extract
Don’t let the name fool you:
Horsetail extract actually comes from a fern-like plant.
It contains silica, an antioxidant that has numerous potential health benefits for your hair, skin, nails and bones.
Vitamin A
Vitamin A helps your body create a natural lubricant, called sebum, that coats, moisturizes and protects your hair and skin.
It can be found in plenty of the foods that make for a balanced diet, including leafy greens, dairy products, carrots, mango and more.
Inositol/B8
Found in fruits such as cantaloupe and orange, inositol – aka vitamin B8 – can help keep your hair from thinning.
Other B Vitamins
While biotin, niacin and inositol are specific types of B vitamins that each play unique roles in promoting thicker hair, vitamin B5, vitamin B6 and pretty much all B vitamins can also be helpful.
Copper
In combination with iron, copper helps form the vital red blood cells that carry oxygen, which helps repair hair cells and stimulate growth.
L-cysteine HCI
An amino acid found that’s crucial to the production of keratin, l-cys has been found to help slow down hair loss.

Promising Review:
Wasn’t sure at first, but this product works! I’ve wanted a good beard for so long but it never grew in right. I had some areas on my face where the hair wouldn’t grow… and the result was too splotchy.
I started growing at the same time I started using the supplement and it’s coming in perfectly! I have a beard now I’m not ashamed of and will keep growing it out to see if I can produce some real fullness. I’m so excited that this product works, definitely give it a try if you’re thinking about it.

I try to use this as much as possible. I can tell a difference in my beard when I’m taking them like im supposed to.
After about a week to two weeks of use people will actually start asking what are you using on your beard now, your beard is looking good, did you start using new oils or balm and so on.

I’ve been using this product on and off for over a year and it definitely works.
The company has said it won’t help you grow hair where you don’t have active follicles, but do say it will enrich the hairs you do have (thicker, darker, and healthier) and it 100% does.

I think it is a great vitamin. I’ve had a bit more energy, and my nail and hair health have both improved. I used to have brittle, broken fingernails that I bit constantly.
Now they look normal and healthy. My hair was beginning to thin out, and hairline starting to recede. But now it feels and looks a little healthier.

I usually consider things like this to be the equivalent of snake oil. I have to say though, this stuff really works. I’ve tried to grow a beard for most of my adult life and only ever managed scruff.
After I started taking these pills, I have an actual full beard on my face. Granted, I’m not going to win any “best beard” awards, but it’s a beard and I get compliments on it. I’m on my fifth bottle now and don’t see myself stopping any time soon.

I love this stuff. I’m on my fourth month and as a man with some balding issues I do notice that my hair is thicker.
Obviously it doesn’t grow overnight and it still has a ways to go but I have noticed a difference and it is amazing what it’s done for my fingernails and my beard.
