What Is Biotin?
Biotin is one of the B complex vitamins that helps your body turm food into energy. You can find it in foods such as egg yolk, nuts and mushrooms.
Biotin is especially important for keeping our hair, skin, nails, eyes and liver healthy.
Did you know biotin is crucial during pregnancy? It is important for the babies growth and development.
You should get enough biotin from foods that you eat day to day but if not and you are struggling with things like hair falling out or brittle nails, you might take a look at biotin supplements.

What Are the Benefits of Taking Biotin?
You have probably mainly heard of biotin when it comes to hair growth. This can be the hair on your head or your eyelashes. My eyebrow lady told me she recommends it for people struggling to grow out their eyebrows (if you are a 00s kid that over plucked, you’ll know the pain)
It can also be helpful for strengthening brittle nails.
Biotin also helps convert food into energy, it is not a magic weight loss pill but biotin is essential for metabolising carbs, fats and proteins into energy that the body can use.

What Dosage Should I Take for Maximum Effect?
Finding the right dosage of biotin is very personal, and important! It really depends on your height and weight and how you usually take to things. I know that I am 5 foot 5 and 8 stone, so would need a little less than someone who is 6 foot 5 and 16 stone.
It also depends if you are taking it in powder or capsule form or even in your shampoo! Our biotin supplements are 5000mcg, providing more than what you need per day but do not exceed the daily recommended dose of 10000mcg . If you want, you can take 2 a day. Hair growth, we’re looking at you!
Researchers don’t think you can overdose on biotin, but we wouldn’t recomened taking more than 2 a day.
We sell 500mcg tablets, which you can get here or on our Amazon.
How Long Does Biotin Take To Work?
When taking biotin, you may be wondering how long it takes to see results. While it will vary depending on your individual needs and other factors such as age or the severity of symptoms, there are some general guidelines for when you can expect to start seeing the effects of biotin.
For me it took around 2 weeks to notice the effects of biotin and it was in my nails. They looked better and felt stronger. Even as I type this, they are hitting the keyboard in a new kinda way!
Here’s how long it might take biotin to work:
Immediately
There is evidence no evidence that biotin will work immediately, sorry if you have had an unfortunate haircut.
Biotin After Two Weeks
You may start to notice your nails looking a little stronger.
Biotin After 30 Days
Not many people report much in the way of hair growth after 30 days but some people report increased energy levels and as it supports your metabolism some people experience a little weight loss, but this is not a substitute for a health lifestyle and eating well!
Biotin After Three Months
This is when some people will start to notice positive changes to their hair. As hair grows in cycles it can take quite a while to see the results from biotin. You might be waiting up to 90 days for biotin to work, so take it consistently.
You can even track your hair growth with a ruler so you can see the results!
Your nails should be feeling longer and stronger by now too.
How To Maximise Effects Of Biotin
To maximise the effects of biotin, it is important to understand the right dosage and timing. Start with a low dose and gradually increase if you feel you need to it as recommended by your healthcare provider or a qualified herbalist, until you reach the full benefits.
I take one tablet a day as I just want to support my metabolism and feel my nails are healthier. I have a bob, so I don’t actually want me hair to grow!
It is also important to remember that biotin works best when taken daily for around 3-6 months, as this works with your hair growth cycle.
Finally, as with any supplement, there can be side effects from taking too much biotin, but it isn’t very likely. As such, it is important to begin with small doses and only increase as your body gets used to the supplement.
Potential Side Effects of Taking Biotin
While biotin is a natural remedy and generally safe to take, there are some potential side effects that you need to be aware of. It is always a good idea to talk to your doctor before taking any new supplement.
Side effects from taking biotin are rare buy may include:
- Nausea
- Stomach cramps / loose stools
- Dizziness
- Thirst
These side effects are very rare, but worth noting. Don’t exceed the daily recommended dose and consider taking breaks from the supplement once you have achieved your hair goal.
If you are pregnant and wondering about biotin then you should speak to your doctor as biotin is generally considered safe when pregnant but speak to your doctor before taking anything.
Conclusion
In conclusion, it’s important to remember that everyone is different and everyone’s body will react differently to biotin. The amount of time it takes for biotin to start working varies from person to person, but most people begin to feel benefits after a few months of regular use, as it works with your hair cycles. However, for the best results, it is advised that you take a biotin consistently for around 3-6 months.
Be sure to consult your doctor before starting any new supplement, as everyone’s body reacts differently to these supplements, if you have any worries at all.
