biotiinimäärät

Biotin, also known as vitamin B7 or vitamin H, is an essential nutrient that plays a vital role in various metabolic processes in the body. It is involved in the synthesis of fatty acids, amino acids, and glucose, and is crucial for the health of hair, skin, and nails. The amount of biotin required by the body can vary depending on age, physiological state, and individual health conditions.

Recommended daily intake of biotin is generally expressed in micrograms (mcg). For infants, the recommended intake is around 5 mcg per day, gradually increasing to 25 mcg for children aged 1-3 years. Older children and adolescents have slightly higher recommendations, with teenagers typically needing around 25-30 mcg daily. Adult men and women generally require about 30 mcg of biotin per day. Pregnant women may need a slightly increased intake, around 30 mcg, while lactating women often require around 35 mcg per day to support both their own needs and those of the infant.

Biotin deficiency is rare, as it is found in a wide variety of foods such as eggs, nuts, seeds, sweet potatoes, and organ meats. However, certain medical conditions, such as genetic disorders affecting biotin metabolism or prolonged use of certain anticonvulsant medications, can increase the risk of deficiency. Symptoms of biotin deficiency can include hair loss, skin rashes, brittle nails, and neurological issues. Excessive intake of biotin is generally considered safe, as it is a water-soluble vitamin and the body excretes what it doesn't need. However, very high doses are sometimes used for specific therapeutic purposes under medical supervision.
