Premature hair loss is one of the most common ailments affecting men and women today. In many cases, hair loss or the inability to grow hair as long as you would prefer has to do with genetics. However, it can also be because of poor dietary choices or simply not getting enough of the right vitamins.

If you’re looking for a natural, healthy way to stimulate hair growth, you’ve come to the right place. This article will look at 9 of the best vitamins for hair growth that can help promote the luscious locks you’ve been dreaming of.

9 Best Vitamins For Hair Growth

Vitamin C

Oxidative stress and anxiety are among the many things that can lead to hair loss and the inability to grow hair. Vitamin C promotes circulation, sending more blood to your head and scalp, which in turn can stimulate hair growth. Vitamin C also helps your body absorb more collagen and reduces the number of free radicals in your body.

Both play an integral role in growing and maintaining a healthy head of hair.

Vitamin B

Vitamin B, specifically complex B-12 vitamins, B7 and B12, are very important in hair growth. As with Vitamin A, Vitamin B helps produce red blood cells and increases blood flow to the head. This, in turn, will lead to follicle stimulation and increased hair growth. While you can get most of the Vitamin B you need through a healthy diet, only some enjoy foods that are heavy in Vitamin B.

While Biotin is technically a B vitamin (B7), it gets its own section because it is arguably the most important vitamin for hair growth. It’s so effective that some hair loss experts recommend Biotin as one of the best treatments to combat hair loss. Biotin helps you grow hair in several ways. As with Vitamin A and other B vitamins, Biotin increases blood circulation to the head and hair.

It also promotes the production of red blood cells, which leads to more oxygen. Finally, Biotin promotes the production of keratin, which is instrumental when it comes to hair growth and follicle stimulation.

Vitamin A

While Vitamin A is better known for its healthy effects on your eyes and immune system, it also plays an integral role in hair growth. The main way that Vitamin A helps with hair growth is that it produces sebum, which is an oily substance in your head that helps your hair follicles stay moisturized.

Vitamin A also aids in producing new cells, which is an integral part of hair growth and follicle stimulation.

The catch with Vitamin A is that you don’t want to consume too much of it. Excess Vitamin A could lead to too much sebum production. While you need some sebum to keep your hair moisturized and healthy, too much sebum will have the opposite effect. Instead of moisturizing your hair, the sebum will build up, clump together, and could lead to hair loss instead of growth.

Vitamin D

Most people associate Vitamin D with healthy teeth and bones. However, Vitamin D also plays an important role in hair growth because it stimulates the growth and production of keratin, which is essential for hair growth. Vitamin D deficiencies are especially common in older people and women.

Although technically not a vitamin, zinc is a mineral and plays a vital role in hair growth. Numerous studies have found that men and women with low zinc levels experience poor hair growth. Zinc is similar to Vitamin D in that it helps produce sebum, which helps moisturize your hair. Zinc also helps keep the oil glands that produce sebum healthy and in good working order.

When it comes to vitamins and minerals, few are as important as iron. Iron deficiencies often lead to anemia, a dangerous condition where your body doesn’t have enough red blood cells.

In addition to creating red blood cells and transporting oxygen to the head, iron is also instrumental in producing hemoglobin.

While these things are crucial for your everyday health and wellness, they’re also important for hair growth.


Keratin is very similar to collagen and other proteins in how it benefits your body. As with collagen, keratin plays an integral role in adding strength and resilience to your nails, skin, ligaments, and hair. While your body produces keratin on its own, it sometimes isn’t enough to promote hair growth.

In addition to hair growth, keratin helps your body produce new hair follicles and keep your hair healthy.

Vitamin E

The final vitamin that is highly beneficial for hair growth and health is Vitamin E. Vitamin E is very similar to Vitamin C in that it helps reduce oxidative stress by eliminating free radicals that can impede hair growth.

To prove its value, a small trial was conducted in 2010 consisting of 38 people.1 In 8 months, those taking Vitamin E supplements experienced a 34% increase in hair growth.

Oral supplements vs. IV therapy for hair growth

While oral supplements and IV therapy are a great way to get vitamins into your body, IV therapy is more effective for hair growth. Vitamin IV therapy gets the necessary vitamins and minerals directly into your bloodstream for a quicker effect. This method will also deliver a more concentrated dosage of the vitamins in question and allow them to work more effectively.

Final thoughts

The inability to grow hair is extremely common among both men and women. It can also be embarrassing and hurt your self-esteem when you can’t grow hair as long and thick as you’d prefer to. While you can try other methods such as creams, lotions, and shampoos, vitamins are one of the best ways to naturally grow longer hair.

However, if you want to get the most out of your vitamins for hair growth, it’s important to ingest them via IV therapy. IV therapy will get these vitamins directly into your bloodstream, where they’ll get sent throughout your body for maximum results.

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.

Who Should Take Vitamin D Shots?

Vitamin D injections may be recommended for people who have a deficiency of vitamin D, which can lead to conditions such as osteoporosis, rickets, and other bone disorders. Injections may also be recommended for people who have difficulty absorbing vitamin D from the gastrointestinal tract, such as those with inflammatory bowel disease or other conditions that affect nutrient absorption. In addition, vitamin D injections may be recommended for people who are at risk of deficiency due to factors such as a lack of sun exposure, a poor diet, or certain medications.

How do I know if I am vitamin D deficient?

The only way to know for sure if you are vitamin D deficient is to get your blood tested. Your doctor can order a blood test to measure your levels of vitamin D and determine if you have a deficiency and if positive increase vitamin d levels.

What are the Side Effects of Taking Too Much Vitamin D?

Taking too much vitamin D can lead to toxicity, which can cause a range of symptoms. These can include nausea, vomiting, weakness, and frequent urination. In severe cases, vitamin D toxicity can lead to damage to the kidneys and the heart. To avoid toxicity, it is important to not exceed the recommended daily allowance of vitamin D, which varies depending on your age and other factors.

So how much Vitamin D do I actually need to take?

The recommended daily allowance of vitamin D varies depending on a person's age, sex, and other factors. In general, the recommended daily allowance for adults is 600-800 IU per day. However, older adults, people with dark skin, and those who have limited sun exposure may need higher doses.

What foods are rich in vitamin D?

There are a few dietary sources of vitamin D, including fatty fish, such as salmon, mackerel, and tuna, and egg yolks. Some foods, such as milk, orange juice, and cereals, are also fortified with vitamin D. However, it can be difficult to get enough vitamin D from dietary sources alone, especially if you do not eat fatty fish or fortified foods regularly.

How does calcium interact with Vitamin D?

Calcium is an essential mineral that is important for maintaining strong bones and teeth. Vitamin D is a fat-soluble vitamin that helps your body absorb calcium. When your body doesn't get enough calcium, it can take calcium from your bones, which can lead to bone loss and osteoporosis. Vitamin D helps your body absorb calcium from the food you eat, so getting enough of both is important for maintaining healthy bones.

How much vitamin D should I take daily?

The daily recommended dosage of vitamin D for children under the age of 12 months is 400 international units (IU), 600 IU for individuals aged 1 to 70 years, and 800 IU for those over 70 years.
