Effective for herpes
Vitamin C is something I constantly purchase throughout the year. I began taking it after a prolonged herpes attack three years ago. This was the first time I experienced such a nightmare. Neither ointments nor antiherpetic medications worked for me; while I took them, there was no herpes, but once I stopped, the rashes returned. A pharmacist advised a course of vitamin C with zinc, and it worked! Herpes has been absent for three years. This vitamin also helps at the first signs of a cold, and my family uses it—adults take 500 mg of vitamin C up to five times a day, while children take 250 mg. The result has been remarkable; my three children have not missed school in two years. I consistently take vitamin C to strengthen my blood vessels, with excellent effects on my health.

I take these supplements with odourless garlic for my sinuses. Consistency has resulted in no sinus issues, and I haven't experienced a sinus infection in over two years.

No ENT infections
I'm thrilled with this product. I had no ENT infections this winter, a pleasant surprise. I previously provided it to my mother in a nursing home, and she too has been infection-free since last summer, which astonished her pulmonologist. I'm quite happy with the results.

Helps with colds
6 people found this helpful
Ester-C is my go-to supplement during illness. Following my doctor's advice, I take 1 g every hour at the first signs of infection, drinking plenty of water. This regime brings me relief and energy quickly. I usually stick to it for three days, and that typically ends the illness, allowing me to avoid pharmaceuticals. Last year, my mother successfully recovered from Covid-19 without other treatments. I also take it daily for preventive measures, as it boosts my strength and makes me sick very rarely. Choosing Ester-C feels safe for my digestive system, as it includes bioflavonoids, and I wholeheartedly recommend it.

Boosts immunity
Vitamin C, or ascorbic acid, is essential for health. It plays roles in bone health, strengthens the immune system, and aids in healing wounds while combating colds. A sufficient intake lowers the risk of respiratory diseases and improves the body's response to infections. It's vital for those suffering from colds since adequate vitamin C intake increases immunity and supports the body's fight against viruses and bacteria.
