About Biotin

Which Vitamin Is Biotin?

No wonder people get in a muddle about biotin. Health science classifies this vitamin in not one or two, but THREE different ways:

  • Vitamin H
  • Vitamin B7
  • Vitamin B8

    Okay, so we’ll try to break this down in as simple terms as possible… wish us luck!
  • Vitamin H isn’t strictly a vitamin in itself. Instead, it refers to a family of B-complex vitamins that convert food into energy.

    As for B7, this is a water-soluble vitamin helping digestive enzymes to metabolise fats, carbohydrates, and proteins.

    Still with us? Phew!

    Finally, there’s vitamin B8, which is known for its role in maintaining skin and hair follicle health.

    We need to get this from supplements or foods, as it isn’t produced in the body.

    How Much Biotin Per Day Is Ideal?

    Dosing recommendations vary considerably, making biotin a pretty unique vitamin in this sense.

    Case in point?

    Between 30 and 100 mcg of biotin per day is thought to be the baseline, essential need for adults. But for strengthening hair, a minimum dose of at least 2000 mcg is often advised.

    To encourage faster hair and nail growth, some supplements are available with 12,000 mcg biotin.

    Although Mayo Clinic states that 10,000 mcg is a safe dose, as no adverse side effects have been noted to date and our NEW Biotin is now 12,000 mcg...reassuringly, even “mega doses” of 300,000 mcg found no side effects in neurological research.

    Are There Biotin-Rich Foods?

    On the upside, you’ve got plenty of biotin-rich foods to choose from.

    The downside is that it can be hard to:

    • Find time to prepare healthy foods from scratch every day
    • Eat the portions of food that are large enough to get sufficient amounts of each vitamin

    Sigh. Too much food, too little time!

    Nevertheless, here are 9 nutritious foods that are known to be good sources of biotin. If possible, try to incorporate a few of them in your daily diet:

    1. Hazelnuts — 61.6 mcg
    2. Egg yolks — 53 mcg
    3. Walnuts — 35.5 mcg
    4. Peanuts — 34 mcg
    5. Oats — 20 mcg
    6. Champignon mushrooms — 16 mcg
    7. Lentils — 9.1 mcg
    8. Carrots — 5 mcg
    9. Soybeans — 4 mcg

    The Benefits of Biotin Tablets

    As we mentioned above, consuming enough biotin through foods alone can prove to be tricky.

    Shopping, recipe research, meal prep…

    It’s a lot to juggle.

    Particularly on Friday nights, when you’re frazzled from work and the 101 other things that have been on your plate that week (sorry about the plate pun!)


    Taking ease of use into account, supplementation makes sense. These 12,000 mcg biotin tablets are a great back-up to save yourself time and energy.

    But before you take the step to buy, let’s examine biotin’s role in health and wellness.

    What’s the Deal with Biotin for Hair Loss?

    WebMD succinctly explains the role of biotin for hair loss:

    “Increasing your intake of biotin may help make your hair stronger and more resistant to falling out.”

    So, if you’ve experienced hair thinning lately, the conclusion above could offer some hope.

    How does biotin work, though?

    Well, you may have heard of keratin. It’s a protective protein that your hair, nails, and skin are made up of.

    Biotin’s relationship to keratin is fairly straightforward— it stimulates the production of keratin.

    In turn, this can have a positive impact on the rate of follicle growth and appearance of hair smoothness.

    How About Biotin for Nails?

    Biotin is listed at the very top of Healthline’s eight nutrients for nail growth. Iron, magnesium, and omega-3s also feature.

    But what about the proof?

    In one study, participants with brittle nails took 2500 mcg of biotin a day for up to six months. 63% saw clinical improvements in their nail health.

    And in another relevant piece of research, a group of more than 70 people took biotin for the treatment of brittle nails.

    91% of the participants had firmer, healthier nails after 3-7 months of taking the supplement. Encouraging!

    Biotin Before and After Reviews

    Before and after stories are always useful to see what effect a supplement has, and in what timeframe.

    Now, we don’t want to go overboard here and list out hundreds of user reviews… but how about we sift through a handful of samples?

    Here’s what users of this 12,000 mcg biotin supplement have said on

    Should I Order Biotin From Boots, Holland & Barrett, or Nutravita? 

    Just like other habits in life, shopping habits can die hard...

    High-street mainstays such as Boots may have been around for decades, but do they give you the best deal when it comes to biotin?

    Let’s put the spotlight on three popular UK brands for the sake of comparison...

    First, Holland & Barrett’s biotin tablets. What do they offer?

    One bottle costs £17.29 (as of March 2021). For that price, you get 100 tablets of 1000 mcg biotin. Customers are advised to take 1-2 tablets per day, providing a 2-4 month supply.

    Moving on, it’s time to discuss Boots’ biotin.

    They have an array of supplements containing the vitamin under different brand names.

    The biotin option on their website with the highest number of reviews is “Vitabiotics Perfectil Original Triple Active.”

    Each tablet contains 45 mcg of biotin, which is a relatively small amount. 90 tablets cost £18.50.

    Last up, there’s the Nutravita Biotin with Zinc Selenium and Copper.

    This high strength, 12,000 mcg biotin supplement has more than 4,400 reviews on Amazon (4.5* average rating) and 800+ reviews on the Nutravita website.

    A one-year supply with 365 tablets costs £19.99. It has been featured as “Amazon’s Choice” in the biotin supplement category

    Hopefully, this gives you a swift outline of what you get with each product. Which one sounds best-suited for you at the moment?


    So, let’s tie things up here…

    We’ve seen how biotin can help nails to grow.

    We’ve seen how it can help hair strengthen.

    And we’ve looked at customer reviews of those who’ve used it themselves.

    A 12,000 mcg biotin supplement may be the perfect choice for anyone concerned that their levels may be depleted.

    Over at the Nutravita store, you can get Biotin 12,000ug with Albion™ Zinc, Selenium & Copper 365 Vegan Tablets. Each tablet has 12,000 mcg of biotin, promoting hair, nail, and skin health.

    Thanks for your time, we appreciate it 🙂

    Can Biotin Cause Acne?

    Healthline states that no studies show biotin supplements cause acne.

    Rather, those with mild to moderate acne who took a supplement with biotin and other vitamins for 12 weeks had significant improvements in acne symptoms.

    How Much Biotin for Beard Growth?

    The data is limited here. Our advice — don’t expect biotin to make a long Viking beard magically appear! But seeing as biotin helps the body to produce keratin (an essential protein in hair), it makes sense that facial hair growth may be supported too.

    Is There Such a Thing as Biotin Deficiency?

    Yes. Biotin deficiency isn’t a common condition, but symptoms to watch out for include:

  • Thinning or loss of hair
  • Brittle nails
  • Red, scaly rashes around the mouth, nose, or eyes
  • Skin infections
  • Lethargy
