Susi Baker –
Easy to take and no after taste
I work in a basement all day with no windows so I started to use this at my doctors recommendation. I take it everyday with my multivitamin. It is so small and easy to take with no after taste.

Came when scheduled and easy to swallow
I’ve only been taking this supplement for a few days. So far, it’s a small pill and easy to swallow. I can’t say that I have noticed a difference in how I feel because I haven’t taken it long enough

10s across the board

Peter McKechnie –
Helped my blood work / labs get better
After seeing some less than stellar vitamin D levels on some blood work I had taken, I took this for about a month before my labs were done again. The 2nd blood labs were so much better, I didnt change any other factors either so I’m pretty confident this works / body definitely absorbs it

Thorne Vitamin D is a top-quality supplement known for its purity and effectiveness. With no fillers, it’s ideal for sensitive diets and provides a balanced dose to support bone and immune health. Though slightly pricier, its trusted quality and potency make it worth the investment.
Iris –
Warning: never take this on an empty stomach. Always have it after food. I made this mistake and puked my guts out.Thats how you know this stuff is potent and made well. After taking this, I felt a difference in my energy levels and mood even. I feel good! This is the only vitamin D where I felt results like this.
