All About Biotin

You may hear a lot about biotin as a vitamin, but what is biotin and what are the benefits of biotin? It plays a role in metabolism. It’s also related to hair, skin, and nail health. Deficiency isn’t common, but can lead to a wealth of problems. Here’s what you should know about the benefits of biotin and side effects of biotin, and all about biotin patches.

What Is Biotin and What Does It Do?

Biotin is a B vitamin. It is often called vitamin B7. You might also hear about vitamin H or coenzyme R. Both of these also refer to biotin. But what is biotin?

Like many of the other B vitamins, biotin is a cofactor in many reactions in the body. It’s a necessary component in normal metabolism. You need biotin in the reactions that let your body break down carbohydrates, fats, and proteins from food and use them to generate energy. These are some of the nutrients whose metabolism requires biotin.

  • Branched-chain amino acids (isoleucine, valine, and leucine)
  • Glucose (from carbohydrates)
  • Methionine (an amino acid from protein) 

Biotin is also involved in other reactions, such as these.

  • Regulation of genetic material
  • Synthesis of cholesterol
  • Synthesis of fat (lipogenesis)
  • Synthesis of glucose (gluconeogenesis)

Some strains of bacteria, yeast, mold, and some plants can make biotin. Some of the bacteria in your gut can even make biotin. Still, they don’t make enough for your needs. You still need to get extra biotin from food or supplements. 

Biotin Food Sources

There are many natural sources of biotin because all living organisms need it. It is in animal-source foods and plant-based foods. Liver and egg yolks have the most biotin. These foods also have biotin.

  • Meat, such as pork, beef, and poultry.
  • Fatty fish, such as salmon, tuna, sardines, and herring.
  • Fruit, such as apples, strawberries, bananas, and orange juice.
  • Vegetables, such as mushrooms, sweet potato, cauliflower, broccoli, and spinach.
  • Whole grains, such as oatmeal and whole-grain cereal.
  • Legumes, such as beans, split peas, lentils, and soybeans.
  • Nuts, such as almonds, walnuts, and pecans.
  • Peanuts and peanut butter.
  • Dairy products, such as yogurt, milk, and cheese.

There are so many natural sources of biotin that many people with an adequate and varied diet do not worry about having a biotin deficiency. They may not see the benefits of biotin because they may never think about it.

Who Needs More Biotin?

It is not common for a severe biotin deficiency to occur in a healthy person who eats an otherwise adequate and varied diet. However, there are times when biotin may be lower. These are some people who may want to ask their healthcare providers about the benefits of biotin supplements.

  • People on weight loss diets. Strict dieting can restrict food intake, leading to a lower overall intake of biotin.
  • Bariatric surgery patients. It’s not just taking in less food that can lead to biotin deficiency. Bariatric surgery patients eat less, and may also eat a smaller variety of foods. It’s possible that they may miss out on some of the best sources of biotin.
  • People who take certain types of medications. Medications for epilepsy or anti-seizure drugs, for example, can interfere with normal absorption of vitamins from food. Antibiotics are another class of medications that may 
  • People who have malabsorption disorders that interfere with nutrient absorption. Crohn’s disease and ulcerative colitis are examples. 
  • People born with a rare genetic disorder that leaves them without biotinidase. This is an enzyme that allows your body to reuse biotin. Instead of recycling biotin multiple times before discarding it, people with this disorder excrete biotin as waste after a single use. 
  • People who are on intravenous feeding. 
  • Pregnant women who are not getting enough nutrients to support themselves and their growing embryo. 
  • People who chronically drink too much alcohol.

If you have any of these conditions or any symptoms of biotin deficiency, it’s best to talk to your healthcare provider about what to do. Your doctor may order blood or urine tests related to levels of biotin in your body. These tests aren’t always completely accurate, though, so it’s a good idea to talk about related concerns, such as whether you are getting enough biotin from the diet. 

Benefits of Biotin for Deficiency

The first benefit of biotin is that it can prevent symptoms of biotin deficiency, or reduce them if you already have them. These are some signs of biotin deficiency.

  • Dry or brittle nails
  • Rash on the skin, or dry skin
  • Brittle hair or hair loss
  • Reduced appetite 
  • Nausea
  • Dry eyes
  • Trouble sleeping
  • Upset stomach or other gastrointestinal issues

If you have any of these signs or any health concerns, be sure to talk to your doctor!

Research on Health Benefits of Biotin

There’s some research on the benefits of biotin beyond preventing deficiency. Multiple sclerosis and diabetes are two of the chronic health conditions that have been investigated.

Multiple sclerosis (MS) is a progressive autoimmune disease. In clinical trials among patients with MS, participants on high doses of biotin have seen more improvements than participants in control groups. 

Diabetes is a condition with high blood sugar. Because of biotin’s roles in glucose and fat metabolism, researchers have looked at whether biotin supplementation can improve blood sugar control. So far, there is some indication that biotin may help, but the results of studies are mixed and inconclusive.

Biotin for hair loss is a popular topic. That’s because hair loss can occur with biotin deficiency. Biotin is definitely needed to prevent hair loss that results from biotin deficiency. In addition, it’s critical to maintain adequate biotin after weight loss surgery, when hair loss is common. 

Another hot topic is biotin for nails. It appears to help hoofed animals with abnormal hooves, and some research has looked at whether biotin can improve unhealthy fingernails. It appears that biotin may support normal nail thickness and strength in some people with thin nails or brittle nails. 

Biotin and collagen are both needed for healthy skin, but they have different functions. Biotin is a cofactor in reactions. It allows them to go forward, but isn’t part of the final product. Collagen is a building block of certain tissues, such as skin. 

Can You Take Too Much Biotin?

Does biotin cause acne? Does biotin cause weight gain? What are the side effects of too much biotin?

Biotin is a water-soluble vitamin and is relatively safe compared to some nutritional supplements. It’s not known to be toxic in high amounts the way fat-soluble vitamins can be. Unlike most nutrients, biotin does not have a tolerable upper level of intake (UL), which is the level above which a nutrient may cause health concerns.

Still, there can be side effects of too much biotin. You’ll want to be aware of a few possible effects. 

  • It can lead to incorrect values on vitamin D tests.
  • It can lead to inaccurate values when testing for thyroid disease. 

It’s also important to be aware that biotin can have an Interaction with vitamin B5. If you are taking high amounts of vitamin B5 (pantothenic acid), there can be competition for absorption. Also, biotin can interact with certain medications, so it’s always a good idea to discuss all of your medications with your healthcare provider when considering a biotin supplement.

Whenever taking a nutritional supplement, it’s important to talk to your healthcare provider first. You want to be sure to get the right dosing. You’ll also want to ask about which other nutrients you might want to take with biotin, as well as which form you want to use, such as a biotin patch.

  • With a patch, there’s no competition with vitamin B5 (pantothenic acid) for uptake in the digestive tract. Instead, nutrients are absorbed transdermally (through the skin).
  • You don’t have to think about whether you are taking your vitamins with or without food. It doesn’t matter when you apply your patch! Just take it off up to 8 hours later.
