Vitamin A does not activate vitamin D. Instead, tiny amounts of A is needed to bind vitamin D to its receptor in our genes. Apparently, the vitamin A is then recycled to be used again while the vitamin D is degraded excreted in the bile and thus lost to the system. This is why one has to replenish vitamin D stores daily but vitamin A stores are more resilient.
