Ideal for reflux

Non-acidic. What's great about this Esther C compared to regular vitamin C is it doesn't cause reflux issues. I am prone to experiencing reflux easily, so Esther C is my choice to avoid those problems.

Really easy on the stomach. I have a sensitive stomach, so I was initially sceptical of the reviews. However, I am pleased to report that I experienced no acid reflux in the morning! I will be purchasing this again.

Cost-effective alternative
16 people found this helpful
Compares to more expensive brands. I have used this product for many years and its quality remains consistent. Its effectiveness is comparable to pricier brands. It can knock out a cold within two days, combining 1000 IU vitamin E and 50 mg zinc. The non-acidic formula is perfect for anyone with acid reflux, like me, as it hasn't irritated my stomach at all.

No irritation experienced
3 people found this helpful
No acid side effects, effective and competitively priced. I prefer this Ester-C version as it doesn't provoke my acid reflux, which can irritate my stomach or bladder. I have no such issues with this product. Although the tablet is slightly large, I can still swallow it. I generally favour tablets over gel capsules as they tend to stick in my throat, and this product doesn’t leave an unpleasant taste.
