Lemon vitamin from 1950s?
 

I've been trying to remember the name of a kind of children's vitamin
that my mom gave us in the late 1950s. It was a sweet, syrupy liquid,
yellow color, with a strong lemon flavor. It did not taste bad, and
none of the kids in my family minded taking it. A typical dose was
one teaspoonful. Does anyone remember the name of this product?

Thanks in advance!
