Vitamin C at 1000mg (200% of optimal) is the star and the reason people buy this. Everything else is sprinkled in at token doses: zinc at 2mg (13% of min effective), manganese at 0.5mg (22% of min effective), B vitamins at fractions of effective doses. For an immune support product, the Vitamin C delivers. Just don't expect the supporting cast to do anything meaningful.

Emergen-C Emergen-C 1000mg Vitamin C: the formulation holds up. Lead: Vitamin C at 1000 mg. Vitamin C at 1000mg (200% of optimal) is the star and the reason people buy this. Clinical dose on the primary, and the panel holds together.
A high-dose vitamin C powder with trace amounts of B-vitamins and electrolytes for everyday immune support.. The 1000mg of vitamin C is exactly what you want for daily immune support. But the supporting cast is severely underdosed. Putting 1mg of quercetin and 2mg of zinc in an immune product is just label dressing. It works fine as a basic vitamin C drink. Just do not rely on this as a complete multivitamin.
