“Since everyone is talking about egg whites.. Avidin should theoretically build up to peak levels in body after 108 days of slamming eggs & I've been doing 12 eggs/day for much longer than that. Aajonus ate over 100,000 raw eggs, it's not like we'd miss a biotin deficiency.”

Biotin (vitamin H or vitamin B7) is a B-complex vitamin that acts as an essential coenzyme for five carboxylases: pyruvate carboxylase, 3-methylcrotonyl-CoA carboxylase, propionyl-CoA carboxylase, and coenzyme for acetyl-CoA carboxylases 1 and 2.[1][2][3][4] These carboxylases help in several chemical processes in the cell, including gluconeogenesis, amino acid metabolism, and fatty acid synthesis.[1][3] The Food and Nutrition Board of the Institute of Medicine recommends a daily dietary intake of 30 mcg/day, for the maintenance of good health. Biotin deficiency is very rare in those who take in a normal balanced diet. Mammals obtain biotin from food. Foods rich in biotin are egg yolk, liver, cereals (wheat, oats), vegetables (spinach, mushrooms), and rice. Dairy items and breast milk also contain biotin.

SUMMARY. 1) A 62-year-old white female developed clinical manifestations of biotin deficiency after consuming a diet containing six raw eggs daily for 18 months

“It's interesting to note the near total absence of medical studies to substantiate the regular claims made about biotin deficiency wrt raw egg-white consumption. On PubMed I can find only two: one study of an 11-y-o boy and another of... cats. Hardly overwhelming. https://t.co/jDafaf74mr”

“Reminder that the one single study people use to say cooked eggs have better protein absorption than raw eggs comes from 5 people without colons or rectums eating modified homogenized egg meals.”
