I don't know the answer to 1 & 2, but I do know of a good protein supplement that I use. It is made from amino acids instead of food proteins, so there is no problem with soy/dairy allergy/sensitivity issues. It is called Alpha ENF and the website for this is http://www.alphanutrition.com (I have no financial connection with this company). You can order the product directly from the website. They have several formulas and also have plain amino acid powder if you want to make your own protein shakes with your own flavors/sweeteners. I hope this helps...good luck,
