“ I went to a dermatologist who just prescribed a shampoo but i knew there was something else to it so i called my family doctor and asked for blood work and turns out my vitamin d levels were extremely low, like in the low teens (normal is between 20 and 50) so i ordered this and started taking it with the biotin from the same brand and honestly speaking it took weeks to see any result so be patient but about 7 weeks in i started seeing less and less hair fall off and just like that it stopped altogether ”

“ My vitamin d levels were low <20, and taking this every other day for a week, than twice a week after brought my levels up to 54 ”
