Excellent Vitamin C

Ester-C is a great vitamin C. I always look for buffered vitamin c because it's much easier on your stomach. I also like quality vitamins, and Ester-C clicks that box. The price at Walmart is excellent, and that's also a consideration when I purchase vitamins. I always get a fast delivery from Walmart which is another plus!

Love these.

My doctor recommended vitamin C to help with both a low iron absorption issue, and also allergies that I deal with year round. I'd tried a gummy one that was 250 mg, but I can't say I noticed a difference. I just finished my first bottle of this one though, and I can definitely say I've noticed a significant improvement these last few months. I take it in the morning half an hour before breakfast and honestly within a week I felt like I noticed that I just felt a bit better already. Will definitely be keeping this as part of my daily routine.

Doesn't upset stomach

Finally a vitamin C that doesn't upset my stomach and a pill that isn't the size of a horse!!! I am ecstatic with this product because I need vitamin C but not when my stomach can't tolerate it, even in fruit. Excellent product.
