I went on vacation in Costa Rica, leaving my Vitamin D pills at home, thinking the same thing.
Not true! I had to shell out like $30 to buy imported Vitamin D tablets because I could feel the positive effects of my Vitamin D supplementation wearing off within 4 days.
And I had gotten enough sun to get a serious tan already.
People process sunlight and synthesize Vitamin D at different levels.

- jmckib 6y agoCould that be in your head? Vitamin D lasts a long time in the body, seems unlikely you'd be able to notice any difference after four days.
- graeme 6y agoDoes it have such a short run effect? My impression is sun/supplementation build up circulating blood levels, and then what’s in the blood is converted to an active substance the body can actually use. For a week long vacation your body would just draw down those stores.
- pacomerh 6y agoSorry but there's no way your Vitamin D levels would wear off in 4 days.
