Relieves chronic cough
Ester-C is reliable and gentle on the stomach. I regularly order it for my mum, who suffers from chronic gastritis and ulcers, as it helps her avoid irritation.

No irritation, effective
Prior to discovering Ayherb, I was unaware of non-acidic vitamin C. I took 1000 mg every other day to boost my iron levels due to chronic anaemia. Unlike ascorbic acid, this form caused no gastrointestinal side effects and helped prevent colds effectively.

Immediate relief
I've taken Ester-C plus 1000 mg for years. When I feel a sore throat or cough coming on, I start with one pill daily, which usually makes it go away immediately. If it persists, I increase to two or three pills.

I bought this for a friend who often felt fatigued and had chronic coughs. After a month, he became more active and no longer suffers from coughs.
