It is a member of the B vitamin family, which helps the body convert food into energy. In this article, we will discuss the benefits of vitamin B7, its sources, and recommendations for optimal health.

Benefits of Vitamin B7

  1. Healthy hair, skin, and nails: Vitamin B7 is essential for maintaining healthy hair, skin, and nails. It helps to strengthen hair and nails, and also promotes healthy skin by helping to maintain the integrity of skin cells.
  2. Energy metabolism: Vitamin B7 plays an important role in the metabolism of carbohydrates, proteins, and fats, which are the body’s main sources of energy. It helps to convert these nutrients into glucose, which is used by the body for energy.
  3. Blood sugar control: Vitamin B7 has been shown to help improve insulin sensitivity, which can help to lower blood sugar levels. This makes it particularly beneficial for people with diabetes.

Vitamin B7 is found in a variety of foods, including eggs, meat, fish, and nuts. Some good sources of vitamin B7 include liver, salmon, egg yolks, almonds, and sweet potatoes.

Vitamin B7 is also produced by bacteria in the gut, but it is unclear how much of this vitamin is actually absorbed by the body.

Recommendations for Optimal Health

The recommended daily intake of vitamin B7 varies depending on age and gender. According to the National Institutes of Health, the recommended daily intake for adults is 30 mcg.

Most people can obtain adequate amounts of vitamin B7 through a balanced diet that includes eggs, meat, fish, and nuts. However, people who follow a vegan or vegetarian diet may need to supplement their intake of vitamin B7.

It is important to note that high doses of vitamin B7 are generally considered safe, as the body can excrete any excess amounts. However, some people may be sensitive to high doses of biotin, which can cause skin rash, acne, and gastrointestinal problems.
