If you are curious about how much biotin you should take per day, it largely depends on your individual health needs and goals. Regular intake of this nutrient, which supports the metabolism of carbohydrates, proteins, and fats, is necessary for optimal health. For most people, getting biotin from their diet suffices, but in some cases, supplementation might be beneficial.

How Much Biotin Should I Take Per Day

Adults who are 19 and over need an average of 30 mcg of biotin daily. A dose of this size helps the body break down carbohydrates, protein, and fats properly. Biotin contributes to the overall health of our hair and skin.

Taking lower amounts of biotin could be beneficial if your diet doesn’t have enough biotin, though symptoms of biotin deficiency are not common in the U.S.

Dr. Donald Mock,M.D., Ph.D., Professor Emeritus, University of Arkansas for Medical Sciences, says that, “The recommended daily intake of biotin for adults is 30 micrograms. However, higher doses are often used safely under medical supervision, especially for certain health conditions. It's important to consult with a healthcare provider before starting any supplementation.”

Can You Take Too Much Biotin?

Not really! Excess biotin has not been shown to cause any harm, even at higher dosages. Clinical studies have used doses as high as 5 mg/day (5,000 mcg/day) for up to two years without adverse events. Nonetheless, always consult with your physician before taking high doses, especially if you are undergoing lab testing, as biotin may alter test results.

Factors Influencing Biotin Dosage

Your reason for taking biotin—whether for hair growth, skin health, or other benefits—will influence the recommended dosage. Exploring the biotin benefits for skin, many users find improvements in skin elasticity and hydration.

People on specific medications or with particular health conditions should consult a healthcare professional before taking biotin.

How Do I Know If I Need More Biotin?

Since biotin is present in most foods, most people can consume enough. However, pregnant or breastfeeding women and those with alcohol dependence might not be getting enough each day.

While biotin deficiency is not common in the U.S., problems may appear if you eat less than 30 mcg per day. As years go by, the gap might result in a shortage. Cracking nails, thinning hair, or losing hair are some symptoms that could indicate a biotin deficiency.

Biotin Supplementation: What to Know

Many people take biotin to improve their hair, skin, and nails, yet the research available is limited. Although biotin is important in energy metabolism and the cells of our bodies, the majority of people already receive adequate amounts from what they eat.

If you are considering using biotin daily, you can choose from three common forms.

• Biotin capsules or tablets
• B-complex vitamins (made up of biotin and other forms of vitamin B)
• Multivitamins that have biotin

They are sold in many places and are frequently advertised as health and beauty products. Even so, you should talk to your healthcare provider to choose the best treatment for your health needs.

In this video, you'll learn about the best natural food sources of biotin (vitamin B7) and how this essential nutrient supports metabolism, hair and nail health, immune function, and more.

Increasing your biotin intake through food is a delicious way to ensure you’re getting enough. Foods rich in biotin include:

When Should You Take Biotin?

Biotin can be taken at any time of day that works best for you. Since biotin doesn’t make you sleepy or alert, taking it at any time won’t influence its effect.

Being consistent is very important. Make sure to consume it accompanied by foods that include some fat. As biotin is essentially flushed out of your system each day, you should aim for a daily intake.

Safety Considerations and Side Effects

Biotin is water-soluble, meaning that excess amounts are expelled through urine, which significantly reduces the risk of toxicity.

However, it's important to note that extremely high doses of biotin can interfere with certain lab tests, potentially leading to inaccurate or false results. For instance, biotin may affect tests that measure hormone levels, such as thyroid function tests, and can also alter the results of other diagnostic tests, including those for heart conditions.

Therefore, it is crucial to always inform your healthcare provider about your biotin supplementation, including the dosage you're taking, before undergoing any medical tests or procedures.
