Drinking enough whole milk to get Calcium RDA would exceed Saturated Fat Upper Limit
Soy Milk usually has the majority of it's Calcium from artificially added Calcium not from Soy

Primary ingredients on most protein powder & protein bar supplements I have seen were either
1 Soy
2 Dairy
Soy unlike most other plant ingredients are almost complete protein

More exotic plant sources are being sold but most unlike Soy do not have complete protein
Animal powders collagen
