Effective treatment
Most Useful Review
When I start to feel unwell with a common cold, I follow nutritionist Katie Young's regimen: Ester C (500mg) four times daily, Zinc picolinate (50mg), and a probiotic (50 billion). This unusual method works remarkably well, helping us feel better in just two days. Vitamin C boosts immunity, Zinc replenishes what we lose during illness, and the Probiotic creates a protective barrier in the digestive tract. We have tested this scheme with the entire family, and I highly recommend it.

I have been taking vitamin C daily for three years, which has significantly improved my immunity and helped me avoid colds.

Vitamin C is crucial for overall health, particularly in instances of disease.

This vitamin also acts as an effective antihistamine. I keep it in my medicine cabinet for illness and use Sodium Ascorbate daily.

I took Ester-C, enriched with citrus bioflavonoids and Lysine, for genital herpes, at a daily dosage of 1000mg. This form of vitamin C is absorbed better, and I noticed fewer rashes with faster healing times. I maintained a sugar and yeast-free diet during treatment, which I believe contributed to my improved immunity. Throughout 2019, I only had one cold, while my family suffered from the flu in 2020—thankfully, I didn’t catch it. I’ve reordered this vitamin and hope my experience helps others.

Significant pain relief
Most Useful Review
Helps reduce back and joint pains. I take 1000 mg (1 gram) of this product twice daily. The effective dosage may vary based on your weight and other factors. I'm male and weigh 185 pounds. The 500mg capsules offer the best value. I do not recommend the caplets/tablets, as they didn't yield good results for me. I started taking Ester-C after learning how its use improved the lives of large breed dogs with hip dysplasia. I had severe lower back pain and wanted to avoid typical OTC pain relievers. It took 2-3 weeks for the product to alleviate my pain, but it has indeed reduced it. If you stop taking it, the pain returns in about 2-3 weeks, indicating some residual effects. Excessive use can cause digestive discomfort. Primarily, I take Ester-C for back pain, and it also assists with hip and joint discomfort.

I bought this supplement out of curiosity, following a new treatment plan for influenza and respiratory infections. At the first sign of illness, I took 500 mg of Ester-C every two hours, along with zinc and vitamin D3. Remarkably, by the next day, my throat felt better, and I avoided antibiotics. By the third day, I was completely well! This approach truly worked for me and was far faster than any medicine I have taken before.
