Per my doctor’s suggestion
Style: 1000IU, Size: 360 Count (Pack of 1)
My doctor advised me that I needed to take vitamin D3 daily in this dose. The gel capsules are really small and easy to swallow. After checking around, I felt that this was the Best Buy for my buck. And NatureWise has a good reputation for quality.

Good value, easy to take, and great quality
Style: 2000IU, Size: 360 Count (Pack of 1), Style: 2000IU, Size: 360 Count (Pack of 1)
I bought these because my doctor recommended Vitamin D3 for overall health and immunity. I’ve tried a few different brands before, and this one stood out as a good balance of quality and value, especially with the 360-count bottle that will last a full year.
Compared to other brands I’ve used, these softgels are equally small and easy to swallow, and the 2000 IU dosage matches what my doctor recommended. I haven’t had any issues with the capsules sticking together, and there’s no noticeable taste or aftertaste.
Overall, a great purchase, and I plan to keep buying.

Good value for the money
Style: 5000IU, Size: 360 Count (Pack of 1)
Odor was not detectable, gentle on the stomach and easy to digest, double check before taking this supplement; it may interact with certain medications, otherwise an excellent product. Good value.

Style: 2000IU, Size: 360 Count (Pack of 1)
This is one of those no-fuss supplements you can actually stay consistent with. The softgels are small, easy to take, and don’t leave any weird aftertaste. Love that it’s in olive oil for better absorption.
