The review
Why we put this on the shelf.
If you only ever take one Thorne product, this is the one most of their medical advisors quietly recommend first. Vitamin D status is the biggest needle-mover in modern bloodwork — low D is linked to bone loss, mood, immune function, and cardiovascular health, and most people who don't supplement run low through winter.
5,000 IU per tiny capsule. NSF Certified for Sport — meaning it's tested for banned substances and label accuracy, the highest bar in supplements. No fillers, no fluff. Pair with K2 if you want the full bone/cardiovascular synergy.
