UltraVit Vitamin D3 4000IU + K2

Six weeks in and my joints feel noticeably less creaky during morning runs, which is exactly why I picked a D3+K2 combo over plain vitamin D. The 4000IU capsules are tiny and easy to swallow, even with my finicky gag reflex. Glad I switched from the cheaper single-ingredient stuff.

I was skeptical about another supplement, but the 4000 IU dose with K2 actually made a difference in how my joints feel during morning runs. The softgel is small and easy to swallow, which is a plus since I hate big pills.

The K2 is the reason I picked this over plain vitamin D, and at 4000 IU the strength actually covers my daily needs. I've noticed my energy stays steady through the winter without that sluggish afternoon dip. Easy to swallow and no weird aftertaste.
