Vitamin D3 Heat Exposure

[PrityCity]

I recently made an online purchase of vitamin D3 which consisted of 500 soft gels per container. However, upon opening the containers I found all the soft gels had stuck together in one large clump.

This must have occurred due to the containers being exposed to heat either during storage at the pharmacy or during transit. The soft gels are easy enough to separate, but I am concerned whether the vitamin D3 would have been affected by the heat exposure.

Is vitamin D3 stable when exposed to such heat or would it now be possibly degraded?

All the vit D softgels I've bought have usually been rather sticky, but the integrity of each one was fine. However, if they were stuck together because the capsules themselves were melted together and the contents leaking, I'd return/toss. Does the packaging say anything about storing in a cool place or avoiding temps above a certain level? You might call the manufacturer. The softgel brand I happen to have says protect from heat; store between 56 - 86F. Probably would have had to exceed 86 for a while in order to actually melt the gel.
