Effective immune booster
Excellent vitamin C. I highly recommend it. I don't take it regularly, but when I feel unwell, I take four pills a day for a few days, and it works wonders. It helps me recover faster even when I'm already ill. I use it sparingly, so it should last a while, but I will order more soon.

Improved immunity
Ester-C with citrus bioflavonoids, along with Lysine, really helps with herpes! This form of vitamin C is retained in the body longer, making it effective. I used it daily for genital herpes and noticed fewer rashes that heal faster. Since taking it, my immunity has improved noticeably—I didn’t get ill during recent flu seasons. I will continue ordering it as the reviews were really helpful.

Skin improvement
For me, Ester-C remains the most effective vitamin C. I take it mainly for my skin, which has improved dramatically over the past two years. I have struggled with problematic skin and noticed results just a week and a half after starting. It boosts my immune system as well, so it's a win-win.

Long-term benefits
The quality of this vitamin is excellent. My family and friends have ordered it for years, and I appreciate the convenient dosage and price. The addition of citrus flavonoids enhances absorption, making this effective and essential for those with autoimmune disorders.

Gastrointestinal safety
Despite my weak gastrointestinal system, this vitamin C doesn’t cause stomach pain or heartburn. It alleviates suffering and is well-tolerated, even with my IBS. I’ll continue to use it.
