What Customers Are Saying
Based on 1 review
Been taking this vitamin D3 for about 3 months now after my doctor suggested I boost my levels, especially during the darker winter months. Really happy with this Windmill brand - the 5000 IU dose is exactly what I was looking for and the price can't be beat at under $10. I've noticed I'm feeling more energetic in the mornings and my mood seems more stable even when it's gloomy outside. The capsules are easy to swallow and don't have any weird aftertaste. My husband started taking them too after seeing how good I felt. Definitely planning to reorder when I run out!
