Ester-c is a unique breakthrough Vitamin C formula supported with naturally occurring metabolites.

Ester-c's unique, chemical-free manufacturing process neutralizes pH, making it non-acidic and gentle on the stomach.

Review: desertcart is the best!! - I have tried other brands of C vitamins finding these to be very easy on the tummy. Great quality and a recommended dose is just right. The pill is easy to swallow and the ingredients are top of the line not leaving anything out. The duration they last is 2 per day which is perfect to take in the morning and not having to think about another dose until the next day. Texture is just like other capsules that are meant to be swallowed whole. Highly recommended!!
Review: Seems to work with calcium supplement to increase bone density. - I am 79 years old, and 6 years ago I was diagnosed as have osteoporosis. Since then, I have been taking a bone supplement that includes calcium and this ester-c. I have had the bone density test every other year as suggested by my doctor, and each time, my bone density has increased rather than decrease as I got older. At this point, I no longer have osteoporosis, but have been diagnosed as having osteopenia rather than osteoporosis. I am hopeful that my bone density continues to increase as I get older with continued use of these supplements. Although a vitamin C supplement may also work for this purpose, ester-c is supposed to have a better bioavailabilty and is easier on the stomach since it is less acidic. To-date, this supplement has not upset my stomach, and my bone density tests suggest that it is effective. Having done my research before taking this supplement, this is rated as a good brand and is of good quality. This supplement is a large capsule, but is easier to swallow than some of the other supplements I take. I do recommend this supplement and hope this review was helpful for you.
