He coped with a cold for just a day! Recently, I fell ill with a headache, sore throat, and general malaise. I had vitamin C available and immediately began taking one tablet every two hours. Remarkably, the next day the sore throat receded, and the headaches subsided almost entirely. This is significant for me because I usually had to gargle and take various preparations, which were often less effective. I now take both Ester-C and iron, believing that this will enhance immunity and optimise iron absorption.

Quick recovery
Excellent! I truly like this product; it’s one of the best purchases I’ve made. The presence of bioflavonoids ensures better absorption of vitamin C, which is crucial. I take one capsule during a cold or when I sense I'm falling ill. There’s definitely an effect as any cold clears up quickly, even sore throats with sharp pains resolve within a day. I wholeheartedly recommend it!

Preventative measure
Excellent! I regularly take vitamin C, one capsule each morning after breakfast. I hardly ever get sick, and if I do, any symptoms, including sore throat, resolve within three days. Even when I had acute angina, I experienced no fever or significant throat pain, just a bit of weakness. I have purchased a second can as this makes me feel wonderful without any discomfort.

Cold symptoms vanished
I took it based on numerous recommendations and was amazed by the effect. My cold symptoms, including a sore throat and a dripping nose, intensified throughout the day. However, after taking 2 capsules before bed, I woke up with no trace of the cold symptoms. I felt revitalised and full of energy, as if nothing had ever happened!

Long-term solution
I have consistently taken vitamin C for three years without interruption, and my entire family does too. We take doses of 500-1000 mg daily for cold prevention. It has significantly enhanced our immunity. I especially love Ester-C, as it doesn't irritate my stomach, which is essential due to my gastritis. Since I began taking vitamin C, my chronic sore throat has completely disappeared, and I haven't needed antibiotics for years.

Cold symptoms reduced
Excellent vitamin C, with a regulated dosage of 500 mg per tablet that covers my daily needs. During its use, I noticed improved immunity and a reduction in cold symptoms, including sore throat. With additional support, recovery happens in a couple of days.

Effective relief
Because of the epidemic, I bought Li Shi. I usually take 2 capsules, but when I have a sore throat or feel a cold coming on, I take 3-4 capsules. I also take it with propolis, and by the next day my throat is no longer uncomfortable.

Combines well
Whenever I experience a sore throat, I use this vitamin to recover more swiftly. When combined with lactoferrin and dextran, fevers and coughs improve dramatically. This product is highly effective and is excellent nutrition, especially for children who dislike medicine.
