Great!
Size: 60 Count (Pack of 1)
My first impression was that the bottle looks nice. The information is clear and the dosage is easy to find. The pills themselves are slightly bigger than other capsules that I have, but this isn't a bad thing. I didn't find them hard to swallow. The smell is pleasant, which is a huge plus! I love the immunity and antioxidant support, that is exactly what I was looking for! Overall, I am happy with the product, and it has been great so far!

Great for immunity!
Size: 60 Count (Pack of 1)
I love elderberry to help my immune system stay strong. I’ve been taking it for years. These pills are easy to swallow and there’s no aftertaste later. I believe they work well since I haven’t caught as much as a sniffle since I started taking them. I would definitely recommend!
