I did a little research and found that the top symptoms in adults for biotin deficiency are hair loss, red-scaly skin and brittle nails. I have all three plus two more that may also indicate biotin (vitamin B7) deficiency.
Long term TPN (more than 1 week) used to be connected to biotin loss but now all TPN is supposed to contain biotin. Biotin is processed in both the small and large intestine. The most common cause of biotin loss in adults is antibiotic use.
I have been a little frightened by losing more than half the hair on my scalp and body. I started taking a biotin supplement of 35 mcg. According to a couple of sources cooked eggs and liver are the highest source of natural biotin.
Thank you for bringing this up blueheron and thank you to Windy City for suggesting that biotin may help. It only takes a few days for the extra biotin to start working. I can't wait!
