Issuing vitamins aboard an age-of-sail warship

How could an age-of-sail crew be made to take a vitamin tablet every day?

Issue it as a mandatory ration, ideally before grog, and explain that it protects against scurvy.

The proposal assumes that vitamin tablets can somehow be supplied to an age-of-sail ship. Issuing a tablet as a daily ration and telling sailors to take it before drinking their grog would fit an established routine. Explaining that it protects against scurvy is another suggested reason for accepting it. There is disagreement over whether the tablet would taste better than ordinary provisions, with hardtack and unpleasant multivitamins offered as comparisons. The expectation is that a ration order would make daily administration fairly straightforward.
