well I've been really getting back into training/working out this summer..its been 3 months now of heavy lifting. I also noticed this summer, right as i coming off a cold (which i did a high dosage of vitamin C to counteract, 1000mg) I noticed i had developed alopecia barbae, which is when your autoimmune system thinks hair folices are enemies, and destroys them; this has happened to a spot in my beard. I don't want it to spread.
I've done some research, and found out that the a cause of hairloss is a lack of certain essential vitamins and minerals: iron, lysine, B-1, and C. Now, my multivitamin, and C supplements take of the vitamin C, and also give me 90% daily value for my iron. B-1 is also included in the multivitamin. However I noticed, im not getting lysine from anywhere. This leads me to believe that a deficiency in this, may have triggered the auto immune system.
