Maybe the most effective thing would be if there were a vitamin D futures market, to bid up the price to incite more production of it. But at the individual level, I think it makes sense to stock up to increase the price a little bit. If you don’t end up needing it, you could always give/sell it to those who do later. The one I bought is good for 1.5 years.
