Vitamin B is great for the immune system and you can usually get your daily dose by eating a balanced, nutritious, and varied diet. But is vitamin B good for eyelashes? 

Is Vitamin B Good For Eyelashes

Yes, vitamin B is good for eyelashes as it helps promote blood flow, strengthen hair follicles, and stimulate keratin production.

What Is Vitamin B?

Although you may hear of ‘vitamin B’ as a shorthand, in reality, vitamin B is a complex made up of eight different types of B vitamins. 

All of these types work in different ways to support a healthy bodily function, and they support slightly different processes in the body. 

That said, you typically need different amounts of each B vitamin, and this will vary between genders.

Can Vitamin B Help Grow Eyelashes?

Can Vitamin B Help Grow Eyelashes

Different types of vitamin B will help grow your eyelashes, so if you’re looking to grow out your natural lashes (and look after your overall health at the same time), it’s essential to consume enough vitamin B.

Some of the best vitamin B complexes for eyelash growth are the following:


Biotin is also known as vitamin B7 and vitamin H and is known for supporting your skin, hair, eyes, and liver, as well as your nervous system. 

It supports cell growth and will contribute to the regrowth of your hair and eyelashes.

It can be found in foods including eggs, almonds, cauliflower, and supplements.

B5 and B6

Vitamins B5 and B6 help you convert the food that you eat into energy and promote healthy skin, hair, and eyes, as well as support your immune system and make red blood cells. 

Find B5 in sunflower seeds, peanuts, chicken, and salmon, and find B6 in soya beans, eggs, poultry, and whole grains.


Vitamin B12 is vital for the healthy growth of hair and eyelashes but is one of the more common B vitamins that people tend to be deficient in – particularly those who are vegan or plant-based. 

B12 is found in meat, eggs, and fish, and can be produced by fermentation.

B2 and B3

Vitamin B2 is also known as riboflavin and boosts your immune system, as well as helps proper digestion. 

It’s also essential for the healthy production of blood cells, which are important for hair and eyelash growth. 

B2 can be found in eggs, soybeans, almonds, leafy vegetables, and red meat. 

B3 is known as niacin and stimulates and supports eyelash growth for thicker lashes.

It can be found in tuna, chicken, avocadoes, eggs, peanuts, and whole grains.

Benefits of Vitamin B

Different B vitamins will provide different benefits, but overall, ensuring that you have sufficient B vitamins in your diet can provide the following benefits:

  • Growth and support of red blood cells in particular, but all cells
  • Digestive function and appetite
  • High energy levels
  • Healthy brain function
  • Correct nerve function
  • Aids fetal development
  • Cardiovascular health

3 Reasons Vitamin B Is Good For Eyelashes

Supports blood flow

If you’re looking to grow your eyelashes, then you need a good blood flow to the hair follicles. 

This will transport oxygen to your follicles, which supports the growth of your eyelashes in turn. 

Vitamin B is essential for the support of red blood cells and stimulating blood flow.

Strengthens hair follicles

By transporting more oxygen to the hair follicles, vitamin B complexes strengthen and support them, which means that they are better able to do their job – that is, growing you lovely long lashes.

Stimulates keratin production

Keratin is the fundamental protein for your hair. 

Biotin, one of the best B vitamins for your eyelashes, stimulates and supports keratin production in the hair shaft, and may encourage follicle growth. 

It’s therefore vital for healthy eyelashes.

How To Use Vitamin B For Eyelashes

How To Use Vitamin B For Eyelashes

One of the most fail-safe ways to support your eyelash growth with vitamin B is by ingesting it either through your diet or in supplements. 

However, if you choose to use a topical vitamin B and apply it to either your skin or eyelashes, take care to always perform a patch test. 

This will help you to ascertain whether you’re sensitive to the formula. 

Avoid direct contact with the product with your eyes, too, as this might cause irritation or infection in the worst instances.


Vitamin B comes in a variety of different forms, and it is best taken through your diet. 

Food like eggs, meat, whole grains, and vegetables contain the vitamin B that you need to support healthy eyelash growth.

An eyelash serum

If you do your research, you’ll find eyelash growth serums that are enriched with vitamin B. 

Applying these directly to your lashes will support their growth and strengthen them, and will instantly apply necessary nutrients.


If you don’t think that your diet provides the necessary vitamin B for your eyelashes and overall health, you can take supplements. 

These can come in pill form or even sprays, depending on your preference.

Risks And Warnings Of Using Vitamin B

It’s unlikely that you’ll overconsume vitamin B if you rely on your diet alone to provide you with enough. 

But, if you double-up with supplements, you may consume too much vitamin B, in which case you should look out for the following:

  • Extreme thirst
  • Abdominal cramps, nausea, vomiting, and diarrhea
  • Blurred vision

If you think you have consumed too much vitamin B, you should consult your physician immediately.
