What is biotin?
Biotin (vitamin B7) is part of the B vitamin family. It plays several roles in helping maintain a normal nervous system, normal skin and energy metabolism.1
Our bodies can’t store biotin, as it is water-soluble.
This is why we have to consume it every day through our diet or supplement routine.
However, the helpful little bacteria in our guts can produce a small amount – thanks guys!

What does biotin do?
It’s a very busy and often underlooked vitamin! Biotin has multiple important functions in the body, including:3
- Processing nutrients from food – biotin supports the enzymes responsible for breaking down the fats, proteins and carbs from our food.
- Supporting energy metabolism – biotin helps to convert the proteins, fats and carbs from our food into energy.
- Helps maintain healthy hair, skin and mucous membranes – biotin helps on a cellular level to reproduce all cells in the body, including hair and skin – which have a particularly high cell turnover.
- Supports normal psychological function – with the help of other B vitamins, biotin can help maintain neurons in the brain.
- Supports nervous system function – biotin works with other B vitamins to help maintain normal nervous system function.
A biotin deficiency can result in skin rashes, hair loss and brittle nails.4
This is why it is commonly found in hair, skin and nail health supplements.

What are the benefits of biotin supplements?
Here are some of the benefits of taking a biotin supplement:
An easy way to get biotin
It can sometimes be difficult to get enough biotin each and every day.
Equally, it can be pretty hard to keep track of unless you’re constantly analysing your diet for its biotin content.
That’s why some people choose to take biotin supplements; think of them as a little insurance in the same way as multivitamins are.
Some multivitamins contain biotin, but they often contain quite a low dosage.
Choosing a biotin supplement or a multivitamin for hair, skin and nails is often the best bet if you want to make sure you’re getting enough.
How much biotin should I take?
There is no current ‘recommended’ intake for biotin like there is for many other vitamins like vitamin C and vitamin D, as more research is needed.
However, the European Food Safety Authority has proposed some Adequate Intake (AI) of biotin:5
- Infants over 6 months - 6ug a day
- Children aged 1-3 – 20ug a day
- Children aged 4-10 – 25ug a day
- Adolescents -35ug a day
- Adults and pregnant women– 40ug a day
- Lactating women – 45ug a day (to compensate for biotin losses through breast milk)
Is biotin safe to take every day?
Yes, you can take biotin every day as long as you stick to the manufacturer guidance – we do need a daily dose for good health after all!
Are there side effects to taking biotin?
Side effects from taking biotin supplements are rare. However, they could cause people to experience:6
Consult your GP if you experience these symptoms.
Also, try taking your biotin supplement with food if you haven’t been already, as taking it alone could be causing these side effects.
It’s also worth noting that if you have ‘extra’ biotin in your body, it will naturally be flushed out of your system when you urinate.
This means that overdosing on biotin is very rare, although still a possibility. Here are the overdose symptoms you should look out for:7
- Low vitamin B6 levels
- Low vitamin C levels
- Drop in insulin production
- High blood sugar levels
- Biotin is an essential B vitamin we need to consume through our diet or supplementation
- You can find it in animal-based foods, seeds, nuts, nutritional yeast and some vegetables like sweet potatoes
- Biotin is needed for breaking down foods and drinks and converting them to energy, maintaining healthy hair, skin and nails, and supporting your nervous system function
- Taking a supplement is an easy and convenient way to get your daily dose (we need it every day as it is water-soluble
- Biotin supplements rarely cause side effects, plus it is quite hard to ‘overdose’ as any extra biotin will be excreted in the urine
