The most common adult dosage of wheat bran, when used as a medicine or dietary supplement to increase fiber intake, is 20-30 grams by mouth daily.
It's important to note that fiber intake recommendations vary depending on age and individual needs. While 20-30 grams is a typical medicinal dose, general dietary recommendations for fiber are usually higher and aim to be incorporated throughout the day from various food sources, not solely bran.
Before significantly increasing your bran intake, especially if you have pre-existing health conditions or dietary concerns, consult with a healthcare professional or registered dietitian. They can provide personalized recommendations based on your specific needs and health status. Increasing fiber intake too quickly can lead to gastrointestinal discomfort such as bloating and gas. It is best to increase your fiber intake gradually and to drink plenty of water.
