Biotin is a water-soluble vitamin that is commonly known as vitamin B7. It plays an important role in the metabolism of carbohydrates, fats, and proteins. Biotin is also essential for healthy hair, skin, and nails.
Many people take biotin supplements for various reasons, including weight loss. However, there are concerns that biotin may cause weight gain. In this article, we will explore whether biotin causes weight gain or not.

What is biotin?
Biotin is a water-soluble vitamin that is part of the vitamin B complex. It is also known as vitamin B7 or vitamin H. Biotin is essential for the metabolism of carbohydrates, fats, and proteins. It helps convert these macronutrients into energy that the body can use. Biotin is also important for the health of hair, skin, and nails.
Biotin and metabolism
The metabolism of macronutrients is heavily reliant on biotin, which plays a crucial role in breaking down carbohydrates, fats, and proteins into a usable form of energy. Biotin is also involved in the production of glucose, a crucial type of sugar that serves as the body’s primary energy source.
Biotin and weight loss

Many people take biotin supplements to aid weight loss. Biotin is believed to help the body metabolize fats more efficiently, leading to weight loss. Biotin also helps regulate blood sugar levels, which can prevent overeating and weight gain.
Can biotin cause weight gain?
There is no evidence to suggest that biotin causes weight gain. In fact, some studies have found that biotin can actually aid weight loss by improving the body’s metabolism of fats. Biotin also helps regulate blood sugar levels, which can prevent overeating and weight gain.
Studies on biotin and weight gain
Several studies have investigated the effects of biotin on weight gain. One study found that biotin supplementation improved glucose metabolism in overweight individuals.
Another study found that biotin supplementation reduced body weight and body fat mass in obese individuals. These studies suggest that biotin may actually aid weight loss rather than cause weight gain.
Biotin dosage and weight gain
The recommended daily intake of biotin is 30 micrograms for adults. Biotin supplements are available in various doses, ranging from 100 micrograms to 10,000 micrograms. There is no evidence to suggest that biotin dosage affects weight gain. However, it is important to follow the recommended dosage and not exceed it.
Other benefits of biotin
Apart from its potential benefits for metabolism and weight loss, biotin also plays a significant role in maintaining the health of our hair, skin, and nails. Biotin is vital for the production of keratin, a protein that is essential for the growth of hair, skin, and nails. Deficiency of biotin may lead to skin rashes, hair loss, and brittle nails.
Natural sources of biotin
Eggs, dairy products, nuts, and leafy green vegetables are some of the food sources that contain biotin. However, cooking, processing, and refining can decrease the biotin content in food, making it challenging to obtain enough biotin from dietary sources alone.
Biotin supplements
Over-the-counter biotin supplements are easily accessible and come in various forms, such as capsules, tablets, and gummies. While generally safe when taken within recommended doses, it’s always essential to consult with your healthcare provider before taking any new supplement.
Side effects of biotin supplements
Biotin supplements are generally safe and well-tolerated. However, some people may experience side effects, including:
- Skin rash
- Acne
- Upset stomach
- Nausea
- Diarrhea
These side effects are rare and usually mild. It is important to follow the recommended dosage and not exceed it.
Conclusion: Does biotin cause weight gain?
In conclusion, there is no evidence to suggest that biotin causes weight gain. In fact, some studies have found that biotin can aid weight loss by improving metabolism and regulating blood sugar levels.
Biotin is also essential for the health of hair, skin, and nails. While biotin supplements are generally safe and well-tolerated, it is important to follow the recommended dosage and consult a healthcare provider before starting any new supplement.
