So, what is biotin?
Everything you need to know about this essential vitamin.
Biotin is a vitamin B complex vitamin that aids in the production of keratin in the body. Keratin is found in hair and nails and boosting the production of keratin helps to boost the growth of hair and nails.
There are many ways to get biotin into your diet, but it is primarily consumed through food. Biotin supplements can also aid in hair and nail growth but it is important to be careful of the dosage for most supplements, as most supplements contain more biotin than the recommended daily dose.
The recommended daily dose of biotin supplements is 30 mcgs but taking between 30 and 100 mcgs per day is fine. Make sure to discuss supplements to your diet with a healthcare provider in case of interactions with other medications.
Biotin supplements should be stored at room temperature, away from heat, moisture, and direct lighting. Supplements should not be stored in the freezer or refrigerator.
How does biotin aid in hair growth?
Why this essential vitamin is important to hair growth and health.
As mentioned before, biotin plays an important role in the production of keratin in the body. Keratin is a protein that makes up the structure of hair and nails. As biotin is a necessary vitamin for the production of keratin, it is one of the best vitamins for hair growth. While research on biotin and hair growth is limited, studies suggest that biotin plays a big role in hair growth and health.
While biotin itself can improve hair growth other nutrients like vitamin D and calcium are also necessary for hair growth. When looking for a hair supplement it is a good idea to look for a supplement that contains all three of these nutrients to get the best results.
What to expect when taking a biotin supplement
How long does it take for biotin to show results?
The first thing you should expect when taking a biotin supplement is that it will take time to see results. In fact, most people who take biotin supplements for hair growth don’t see results of the supplements until months later. Don’t let this discourage you! While biotin can take a little while to show its powers, many people have seen amazing results from taking a supplement.
In an article published on naturallycurly.com, readers were asked whether they’d used biotin supplements and if so, what the results had been. Those who used the biotin supplements for 3-6 months or more saw results in their hair growth and health, while those who used a biotin supplement for less than a month saw little or no results.

How to speed up hair growth
What can you do to speed up hair growth?
Truth be told, it is unlikely that you will get your hair to grow any faster than it does on a biotin supplement. While it may be frustrating to wait for many months to see slow improvement to hair health and length, there is little to be done to drastically speed up your hair growth.
The best thing you can do to boost your hair growth is to take a biotin supplement that contains other nutrients as well, and eat a balanced diet full of biotin-rich foods.
Some biotin-rich foods include:
- Egg (more specifically the yolk–don’t just eat the egg whites.)
- Most dairy products
- Nuts
- Legumes
- Avocados
- Mushrooms
- Brassicas (broccoli, kale, cabbage and other hearty greens.)
- Pork (in particular liver and kidney meats.)

When it comes to hair growth, patience is key. That said, biotin supplements can certainly help to speed up your hair growth and can greatly improve hair health. As with any supplement, it’s important to discuss options with your healthcare provider and stay within the recommended amount per day of biotin, which is 30 to 100 mcg according to the Mayo Clinic.
While biotin is relatively safe, it is important to know the signs of a potential overdose of biotin even if such an occurrence is extremely rare. Signs of a biotin overdose may include symptoms such as:
- Slower production of insulin
- Higher blood sugar
- Breakouts of acne around mouth and jaw
- Mild nausea, diarrhea, or stomach cramping
Your hair journey is personal and important. Whether you decide to take a biotin supplement because of health issues or cosmetic concerns, there are many things to consider when looking for a biotin supplement for hair growth.
Supplements should contain the recommended amount of biotin (between 30 and 100 mcgs) and have other nutrients such as calcium or proteins to boost hair and skin health.
