From short stubble to a full beard—facial hair is in, and it’s not going anywhere. However, if you are like the millions of men that struggle with beard growth, you might need a little help getting your facial hair where you want it. 

The good news is that there are many naturally derived ingredients that are shown to encourage beard growth. That means a thin or patchy beard can benefit from formulas found in facial hair products.

Unfortunately, not all beard growth supplements are created equally, and if you pick the wrong one, you could be working against your facial hair goals. That's why more and more men are turning to beard growth supplements with premium ingredients. 

So we put together this comprehensive guide to help you get a handle on the best beard growth products. Smarter Reviews has done extensive cross-market research and arrived at our top 5 quality hair vitamins for a thicker, fuller beard.

Why Healthy DHT Levels Mean Healthy Beards

Stress, genetics, and age are all factors that contribute to a lack of beard growth. But it's also important to maintain a proper balance of DHT (dihydrotestosterone), a hormone that helps regulate hair growth.

Low DHT is one of the most critical factors in the lack of beard growth and patchy facial hair. And that's where high-quality beard growth supplements come in. These supplements contain specific ingredients that properly regulate the production of DHT, promoting follicle growth.

Now that you understand the importance of DHT in maintaining healthy hair growth, let’s figure out which ingredients might have the biggest impact!

Look for These Supplement Ingredients 


This popular nutrient protects and helps rebuild hair from damage due to environmental conditions.

Vitamin A

This essential vitamin plays a large role in the health of epithelial tissue which is responsible for hair growth

Hydrolyzed Collagen

Collagen helps build keratin (the protein that makes up most of your hair) and promotes circulation. More blood flow helps create new hair follicles, and repairs and strengthens existing hair.

Saw Palmetto

Saw palmetto is a potent berry extract that plays a key role in promoting healthy DHT levels. This naturally occurring hormone contributes to the normal thinning of hair associated with age by shrinking hair follicles.

Zinc & Iron

Zinc aids in testosterone production which helps strengthen hair follicles. Iron increases blood flow which allows more essential nutrients to stimulate hair follicles for improved growth—while low iron levels can cause facial hair to become dry, brittle, and even fall out. 

Ingredients to Avoid 

Magnesium Stearate

This "flow agent" may seem harmless, but in reality, it might be troublesome. Unfortunately, most sources for magnesium stearate are genetically modified, and treated with high amounts of pesticides, due to its origins as a cottonseed oil base.

Titanium Dioxide

Widely relied upon in vitamin manufacturing as a coloring agent and binding mineral, it has been banned in food by the European Union due to genotoxicity concerns. Low-quality hair vitamin blends in the U.S. could include this filler.

Fortunately, for men looking to promote beard growth, there are a few good products out there that meet most if not all of these criteria.

At Smarter Reviews, we employ a comprehensive evaluation system to analyze and measure the full value of products. Specifically, we look at the safety, projected effectiveness, clinically studied ingredients, return policies, and overall customer satisfaction of each product.
