Great product

### ⭐⭐⭐⭐⭐ Quality
*by E***E on January 14, 2026*

This brand is recommended by my rheumatologist. It is a good product.

### ⭐⭐⭐⭐⭐ These work!
*by H***N on February 23, 2022*

For several years my doctor told me that I had low Vitamin D and should work on raising it. I did some research and found that these are a good quality Vit D supplement that your body can absorb. Are several months of taking these I had my blood work done and my Vit D levels were normal. I take 1 every morning with my meds and breakfast. I swallow them whole so the quality of taste is N/A for me. I am so glad that I added these to my daily regimen especially before these last two years with the pandemic.
