The recommended daily intake of vitamin B7 varies depending on age, gender, and other factors. According to the National Institutes of Health, the recommended daily intake of vitamin B7 is as follows:

  • Infants: 5-6 mcg/day
  • Children: 8-12 mcg/day
  • Adolescents: 25 mcg/day
  • Adults: 30 mcg/day
  • Pregnant women: 35 mcg/day
  • Breastfeeding women: 35 mcg/day
One key takeaway from this text is that vitamin B7, also known as biotin, is an essential nutrient that plays a critical role in the metabolism of carbohydrates, proteins, and fats, and is essential for maintaining healthy skin, hair, and nails. To ensure you get enough vitamin B7, you can incorporate foods like egg yolks, nuts and seeds, liver, dairy products, and fatty fish into your diet. Vitamin B7 toxicity is rare, but it’s important to let your doctor know if you’re taking biotin supplements, especially if you’re undergoing lab tests.
