Good but not excellent it comes in solid tablet forum. California Gold Nutrition, Vitamin C, Quali-C, 1000 mg for me work better.

I find most vitamin C harsh on my digestive tract, but never had a problem with Ester C. I find taking Ester-C daily helps my avoid colds and sinus infections

Excellent Ester-C product. However, I have recently learned that time release ascorbic acid without being buffered or modified (i.e., ascorbyl palmitate) is probably a better choice.
