Have used this fot a while seems to do the job.

Vitamin D3 is Vitamin D3...Brands all seem to be the same. Helps to keep me healthy.

The bottle is easy to open and the flip back cap helpful. The size was easy for me to swallow.

Good vitamin reasonably priced

Small softgel, easy to take.

I can tell a huge difference in energy levels after taking this!

Package was left in the mailbox which is exposed to the sun for more than eight hours.

Compared to Walmart, grocery stores & pharmacies, Sam's offers the best value for this vitamin.

better deal than Puritain's Pride.

Using per doctor with calcium.
