Can too much vitamin a lead to renal failure?

Possibly. Taking very large amounts of vitamin d can potentially lead to too much calcium in your blood. That, in turn, can potentially lead to kidney damage, among other things. You would probably have to take an absurdly large dose over a prolonged period of time for this to happen.
Vitamin A. Vitamin a is a fat soluble vitamin. In general if you have poor kidney function it may result in accumulation. It is not known to cause kidney failure. However metabolism and excretion of all substance can tax the kidney or organ that is responsible for clearance. Common sense says dont use excessive amounts. High dose vitamin bs have been linked with worsening kidney function as an observation.
