Approximately 33 percent of men in the U.S. have a beard.

Do you want to be part of this group? Do you have questions like “How fast does a beard grow?” or “How can you get it to grow faster?”

If so, read on to learn the answers to these and your other most pressing beard growth questions.

How Fast Does a Beard Grow?

Everyone’s facial hair grows at a slightly different rate. On average, though, facial hair grows about 0.3-0.5 millimeters every 24 hours. Over an entire month, that works out to about 0.33-0.5 inches per month.

Factors That Slow Down Beard Growth

If your beard doesn’t grow this quickly, there are quite a few issues that could contribute to that issue. The following are some of the most well-known factors that can slow down a person’s beard growth:

  • Low-calorie diets
  • Lack of vitamins or minerals
  • Low testosterone
  • Damaging haircare practices

There are lots of issues that can affect your beard growth. Luckily, though, there are also lots of steps you can take to address these issues, such as cleaning up your diet, exercising on a regular basis, and using the right supplements.

Best Beard Growth Supplements

Some supplements have been shown to be very effective when it comes to supporting beard growth. The following are some of the best options to add to your medicine cabinet:


When it comes to supporting hair growth, biotin (vitamin B7) is one of the most frequently talked about supplements.

Biotin can increase levels of keratin. Keratin is an essential protein that makes up the hair, skin, and nails.

Supplementing with biotin on a regular basis can increase facial hair growth (as well as hair growth on the head). It offers other benefits, too, including reduced inflammation, improved cognitive function, and reduced blood sugar in people who are diabetic.


Collagen is all the rage these days, especially among folks who need some extra support in the hair and beard growth department.

Collagen is another abundant protein that plays a vital role in hair, skin, nail, and joint health. Collagen supplements are loaded with amino acids that the body uses to support hair growth (as well as the growth of other tissues).

Collagen can also act as an antioxidant. It protects against free radical damage, which can affect the hair follicles and stunt hair growth.

Vitamin B5

Vitamin B5, also known as pantothenic acid, is a commonly used ingredient in hair and beard growth supplements.

Vitamin B5 supports and protects the adrenal glands. When the adrenal glands are not functioning properly, hormone production gets thrown off, and hair growth slows down.

As an added bonus, vitamin B5 can also minimize graying hair. If you’re struggling with grays in your beard as well as a reduction in beard growth, adding B5 into your diet could be a good option.

Vitamin D

If you lack vitamin D, you may be more prone to hair loss and stunted beard growth. This is because vitamin D stimulates new and old hair follicles.

A deficiency in vitamin D is also connected to the autoimmune disease alopecia, which is characterized by bald patches on the scalp and throughout the body.

Vitamin D supplementation is an easy option for boosting levels and supporting beard and hair growth.

You can also support your body’s vitamin D levels by exposing yourself to the sun on a regular basis. When you’re exposed to the sun, the body converts cholesterol into vitamin D.


Zinc supports hair growth by supporting the oil glands located around the hair follicles. It ensures these follicles work properly so that your hair growth doesn’t slow down or stop altogether.

Zinc supplementation can be a great option for folks struggling with slow beard growth. It’s important to note, though, that excessive zinc intake can actually cause hair loss. It’s a good idea to get your zinc levels tested before you start supplementing with it to avoid taking too much.

Saw Palmetto

Saw Palmetto is a natural version of minoxidil. Minoxidil (found in Rogaine) is a common medication prescribed to folks struggling with hair loss.

Saw Palmetto blocks DHT, a hormone that, in high levels, can contribute to hair loss and stunted hair growth. It also increases the length of the hair’s growth phase. When you use it, you’ll have more hair growing at once, which sets you up for a fuller, longer beard.

Horny Goat Weed

It has a silly name, but horny goat weed is actually a very effective supplement for those struggling with slow beard growth. That’s why it’s a primary ingredient in our AgelessTEST supplement.

Horny Goat Weed stimulates blood flow. It also increases testosterone production.

Both of these factors improve hair growth. They also strengthen the hair so that it’s less prone to breakage and damage in the future.


Ashwagandha is an adaptogenic herb. These kinds of herbs help the body to adapt to stress. They also promote better hormone balance.

There is some research that shows ashwagandha, specifically, can help to increase testosterone levels. By increasing testosterone, you can set yourself up for faster hair growth and a thicker, healthier beard.


Fenugreek is a leafy green herb that originates in southern Asia and the Mediterranean. It’s used in traditional Chinese and Ayurvedic medicine for a variety of conditions, including digestive issues and skin irritation.

Fenugreek seeds also make an appearance in many hair growth products (including our AgelessTEST Supplement). This has to do with the fact that they are a good source of iron and protein.

Fenugreek also has antifungal and anti-inflammatory properties, both of which are important for healthy hair follicles.
