2. Biotin
• The water-soluble Vitamin B7, Biotin, was also
known as Vitamin H until it was found that both
substances were identical. Subsequently the name
Biotin replaced Vitamin H.
• Biotin is important for fat, carbohydrate, and protein
metabolism. It is also involved in glycogen synthesis and
supports the utilisation of other nutrients
3. Biotin Deficiency
• Deficiencies rarely occur. Biotin is widely distributed in
foods and our body can synthesize small amounts by
bacteria in the intestine.
• However, a substance called avidin binds Biotin and makes
it unavailable to our body. High consumptions of raw egg
whites should therefore be avoided.
4. Benefits of B7
• helps to regulate blood
sugar levels and promotes
healthy skin, hair, and nails.
• It is important in the
metabolism of fatty acids,
for energy production and a
healthy nervous system.
5. Biotin Deficiency

•
•
•
•
hair loss
hallucinations
loss of appetite

7. REQUIREMENT
• Sufficient scientific evidence to establish a Dietary
Reference Intake (DRI) is not available. Instead, the
suggested Adequate Intake (AI) developed by the Food
and Nutrition Board (FNB) at the Institute of Medicine
of The National Academies currently states 30mcg for
adult men and women. No Tolerable Upper Intake Level
has been established for Biotin. Australia and New
Zealand state 30mcg for adult men and 25mcg for adult
women as their adequate Intakes (AI)
