Hiya James, Thanks for the article and the warm welcome! I noticed that you like the Solgar multivitamin- is there a reason why you prefer it over others? Also, as a vegan or vegetarian, do you find it challenging to naturally supplement with Arginine, Lysine and Taurine? What is your view on amino acids? As for me, I've been a vegan for the last year, and I've found recently I am zinc and iron deficient. Do you have any suggestions for diet or supplements aside from taking zinc and iron supplements? Thank you in advance Vanessa
