Can You Get Too Much Biotin?

If you’re like me, you’ve been taking Complete Biotin Plus every day and reaping the benefits. Thick, split-end free hair, unbreakable nails, increased energy, and more. But you may have noticed that my formula has 1750 mcg of biotin in it. While this may seem high, if you check most other store-bought biotin supplements, you’ll notice they have FAR more – some of them up to 10,000 mcg!

For those store brand supplements, they jack up the dose so high because they know that hardly any of it will get absorbed. So, they heavily increase the amount, hoping that your body will take in at least some of it.  

For EverBella, we’ve increased ours from the recommended daily intake (RDI) so that you can have biotin in your system at ALL times. That’s the best way to get its full benefits. And, the RDI is really only the amount to avoid a deficiency. If you get 100% of your RDI every day, you’re really just toeing the line. 

But still, even with all of this being said, you still may wonder if you can take too much biotin. Is there such a thing as a biotin overdose or biotin toxicity? 

Keep reading to find out! We’re going to cover these questions, as well as a few basics of biotin just as a refresher. 

What is biotin?

Biotin (or vitamin B7) is one of the many water-soluble B-vitamins that are necessary for your body to function. One of its main roles in the body is to metabolize macronutrients in order to regulate your metabolism. Another key role of biotin is in the nervous system, by helping the brain transmit nerve signals. B vitamins protect your brain and improve your memory and concentration, and biotin is no exception.

Another major function of biotin is creating the protein that makes up your hair, nails, and parts of your skin – keratin.

What are the benefits of biotin?

Biotin plays an important role in metabolizing glucose, fatty acids, and amino acids. Its role as an enzyme in the metabolism of amino acids is crucial for protein creation – like keratin – which results in building strong, healthy hair and nails.

Clinical trials have shown that it can help reduce brittle nails that easily split or crack. [1]

And participants in a Switzerland study saw a 25% increase in nail plate thickness following biotin supplementation. [2]

The same goes for healthy hair. Studies show that individuals with a biotin deficiency can benefit from supplementing biotin to help with hair growth. [3]

And when researchers have looked at people who have hair that’s brittle, unhealthy, or just refusing to grow, they’ve found that most of them are low in biotin! [4]

Hair is easily damaged by sun-exposure, overwashing, and constant heat from the hairdryer or other styling tools. As mentioned above, biotin plays a role in building the protein that helps regrow healthy hair, which is why it has become such a popular hair and nail supplement.

What are the signs of a biotin deficiency?

Symptoms of biotin deficiency typically come on gradually. [5]

These symptoms include:

  • Thinning hair and hair loss on all areas of the body
  • Brittle nails
  • A scaly red rash around the eyes, nose, and mouth

In the most severe cases, a biotin deficiency can lead to:

  • Neurological conditions such as depression
  • Lethargy
  • Hallucinations
  • Tingling of the extremities

Those with a genetic disorder for deficiency in biotinidase – an enzyme that helps recycle biotin to be reused by the body – are at a higher risk of deficiency. Pregnant and lactating women should also be mindful of their intake. At least a third of pregnant women develop a slight deficiency regardless of normal intake, because the process of lactation lowers biotin levels.

So, can you get too much biotin?

Biotin is water-soluble. This means that there’s no official upper limit for biotin because your body only stores what it needs. The rest is simply excreted in your urine. 

The normal recommended biotin dosage for adults is 30 to 100 micrograms (mcg) per day. But as I mentioned earlier, this is quite low, especially if you’re looking to experience ALL of the benefits biotin has to offer. If your levels are just barely high enough, your body may use the little biotin it has to help with regulating the metabolism instead of growing your hair. While regulating your metabolism is good, you want it to do both, of course!

But while you could be getting too little biotin, there’s no evidence of high levels of biotin being harmful or causing toxicity. Research has suggested that even mega-doses of 300 mg (that’s 300,000 mcg) to help with treating multiple sclerosis have no adverse side effects. [6]

One caveat is that taking a lot of biotin can interfere with lab test results. The technology used to measure levels of thyroid hormones and vitamin D, for example, can show high or low test results. For this reason, it’s important to inform your doctor if you’re taking a biotin supplement. [7]

The other side effects of too much biotin are pretty nonexistent, but if you take too much of the biotin supplements beyond 10,000 mcg, you could potentially encounter digestive issues, as your body is working to flush out the excess biotin.

All of this being said…

You want to make sure you’re taking a biotin supplement that can actually get absorbed by your body and sent to where it needs to go. Why bother taking 10,000 mcg and crossing your fingers, hoping that your body not only takes it in, but allocates it properly?

EverBella’s Complete Biotin Plus is designed to be fully absorbed and used by your body. If you’re looking for results, this is it.

I’m so confident in my formula, that I give you 6 months to try it. If you’re not completely satisfied, simply return your order for a FULL refund.
