Can Taking Biotin Supplements Break Your Skin Out?

Let's talk about biotin. If you haven't heard of it by now, where have you been hiding? Our bodies need biotin (vitamin B7 or vitamin H) to function, but it has additional benefits too. According to Icahn School of Medicine at Mount Sinai, the vitamin is necessary for metabolizing carbs, fats, and amino acids in the body. People who suffer from brittle nails and thinning hair typically have a biotin deficiency. Fortunately, there are several supplements and products on the market proven to grow and strengthen your hair and nails, while also improving your skin. You can also raise your biotin levels naturally by consuming cooked eggs, almonds, and legumes.


Now, it's clear biotin has its advantages, but what about its potential disadvantages? People have reported negative reactions, saying they've had issues with their skin breaking out after taking biotin supplements, but what's the truth? It's time to uncover the truth about acne and biotin — are the supplements really to blame?

The answer is complicated

Biotin can do wonders for the skin, especially if yours is on the drier side, WebMD states. The vitamin can make your skin feel much more hydrated and smooth, and significantly enhance its appearance, too. Unfortunately, biotin doesn't work the same for everyone. Some blame the vitamin for breakouts, but as of right now, there is no evidence that biotin is the cause for acne. However, there is a correlation between the two. According to Stryx, taking biotin supplements can block absorption of other nutrients, which in turn, causes your skin to break out.


Vitamin B5 is responsible for preventing acne, so when vitamin B7 takes over, your skin is more prone to pesky breakouts. Think of it as a war for your body's attention: There can only be one winner (unfortunately, if it's biotin, your skin suffers). While biotin isn't responsible for acne, there is research that proves biotin supplements can result in irritated skin and even rashes, Dr Emil Nutrition explains.

How to improve your skin

If you've dealt with breakouts after taking biotin supplements, luckily, there is a way to improve your skin without depriving your body of the vitamin. Stryx recommends taking a multivitamin instead of straight biotin supplements. This way, you can have your vitamin B7 cake and eat it too. As we mentioned earlier, a biotin deficiency has its drawbacks, so it's important you're getting the recommended daily dosage. According to Mayo Clinic, adults and teens should intake 30 to 100 micrograms a day.


If you have a known deficiency, however, speak with your doctor to figure out which dosage is right for you. Remember, every body absorbs and reacts to vitamins differently, and while biotin may not be the direct cause of acne, it can boost your chances of breakouts, so be sure to keep an eye on your skin after ingestion. Clear skin is happy skin, and happy skin means a happier you.
