Overview
A buffered form called Ester-C is the working ingredient in this American Health capsule, sold as non-acidic and gentle on the stomach. Citrus bioflavonoids are added, and the capsule is vegetarian with a citrus flavor.
The reason to look at it is the stomach friendly vitamin C paired with bioflavonoids in an allergen-free formula. The limitation is that the supply covers about two months at a full serving and the data gives no directions.
Who it's for
Adults who find ordinary vitamin C tablets harsh, and who follow a vegetarian diet, will find this format kinder. A buyer who wants a large bottle for a family, or who prefers a powder, should look at other formats.
Pros and cons
- Non-acidic vitamin C
- Citrus bioflavonoids added
- Several capsules per serving
- Directions not in the data
Performance notes
Ester-C is a buffered vitamin C, meaning the acidity is neutralized so it is less likely to upset the stomach. Bioflavonoids are plant compounds often added alongside vitamin C. The capsule shell opens in the stomach, and the label sets the number to take.
