The shelf life of D3 varies, depending on the type (gel capsule or tablet), exposure to light and oxygen, moisture content in the air, and ambient temperature. Also, depending on the additives used by various brands the shelf life may vary. D2 is less stable compared to D3. read more

What I mean by this is not the shelf life in the body but the shelf life of the tablets, capsules or liquid supplements in the cupboard :) Some information I found states that vitamin D will oxidize quickly and once exposed to oxygen will be depleted in 3-4 weeks rendering the tablets or other forms of the supplement pretty much useless. read more
