A healthy, full beard symbolizes masculinity and confidence for many men. However, the road to an enviable beard can be more complicated than many think. Growing a thick, luscious beard can sometimes be a challenge. Genetics, hormones, and overall health can all impact facial hair growth. 

The good news is some vitamins may benefit the process. This article will examine eight essential vitamins for beard growth, their benefits, and how they work.

Biotin (Vitamin B7)

One of the most well-known hair-boosting nutrients is Biotin, vitamin B7. A water-soluble vitamin B7 is vital in keratin synthesis, the primary protein responsible for hair structure. It can help improve hair strength,1 reduce hair loss, and stimulate new hair growth.

Incorporate foods like eggs, nuts, seeds, and whole grains into your diet to boost your biotin intake, or consider taking a biotin supplement.

Vitamin D

Low vitamin D levels are often associated with hair loss2 or thinning hair.

Maintain optimal vitamin D levels by ensuring sufficient exposure to natural sunlight. Additionally, you can consume foods rich in vitamin D, such as fatty fish, fortified dairy products, or supplements.

Vitamin A

Vitamin A3 is vital for healthy hair growth, as it helps regulate sebum production, a natural oil that moisturizes the hair and scalp. Vitamin A positively affects beard growth and growth and is significant in cell growth and differentiation.

Increase your vitamin A intake by consuming sweet potatoes, carrots, spinach, and cantaloupe, or take a supplement.

Vitamin C

To ensure you get enough vitamin C, consume foods like oranges, strawberries, bell peppers, and kiwis, or take a supplement.

Niacin (Vitamin B3)

Niacin, also known as vitamin B3, has promising benefits for hair growth. Niacin may help improve blood circulation to the hair follicles, supplying them with essential nutrients. It also plays a role in cellular energy production, impacting hair growth.

Foods rich in niacin include turkey, chicken, peanuts, and mushrooms.

Folic Acid (Vitamin B9)

Eat foods like leafy green vegetables, beans, and whole grains to boost your folic acid intake, or take a supplement.

Vitamin B12

Vitamin B12 is critical for brain function and the formation of red blood cells. However, a deficiency in vitamin B12 can also lead to hair loss and slow growth.

Vitamin B12 is abundant in beef, liver, dairy products, and fortified cereals.

Oral Supplements vs. IV Treatments

Many of the nutrients we have listed are abundant in foods. While a healthy diet is ideal, some situations may arise that require additional solutions to get vitamin levels to where they need to be.

For example, some may need help with nutrient absorption and require simply ramping up their intake to a not sustainable level through food. That’s where oral supplements come into the picture. They are a popular solution for getting more vitamins into the body.

However, while oral supplements can provide a good source of vitamins, they may not be as effective as an IV treatment. IV treatments inject high concentrations of fluid, nutrients, and even medications directly into the bloodstream, allowing it to bypass the digestive system, making the nutrients 100% bioavailable. IV treatments can quickly restore low vitamin levels and provide more immediate benefits for hair growth.


A well-groomed, healthy beard is desirable for many men, and ensuring optimal vitamin intake can help achieve this goal. The eight vitamins discussed in this article are a promising, natural way to promote beard growth and overall hair health. By incorporating these vitamins into your diet or supplement regimen, you can support your facial hair growth.

Remember that while oral supplements can be helpful, IV treatments may offer a more efficient and effective way to promote healthy beard growth. Consult a medical professional to help determine the most suitable for your needs and beard goals.

Vitamin D Shots - Frequently Asked Questions

Can you take too much vitamin D?

Yes, it is possible to take too much vitamin D. Vitamin D is a fat-soluble vitamin, which means that it can build up in the body and potentially lead to toxic levels if it is consumed in large amounts. Vitamin D toxicity can cause hypercalcemia, a buildup of calcium in your blood. This condition can cause symptoms such as weakness, nausea, vomiting, frequent urination, kidney problems, and more.

How often do you need vitamin D shots?

Frequency of treatment depends on individual circumstances such as the severity of vitamin D deficiency, medical history, and other factors. However, most people may receive 1 – 3 shots over the course of a year.

Are vitamin D shots better than oral supplements?

Yes. Because vitamin D shots are given intramuscularly, the ingredients bypass your digestive system so that the full dose is available to your body for maximum benefits. Vitamin D shots are rapidly available for your cells to use.

What happens if you don’t treat vitamin D deficiency?

Not treating vitamin D deficiency can cause rickets, a rare but treatable condition that causes fatigue, frequent illnesses, depression, and impacts bone and muscle health. In children, vitamin D deficiency can impact normal growth and development.
