It’s the best vitamin C I ever had. Thanks to my doctor who recommended it! It’s non-acidic form doesn’t provoke any reactions, as regular vitamin C does. I feel so much better since I’m taking it for a few weeks. I order it for my whole family.

Many clients reorder, which reflects the product’s quality and reliability. It’s a well-known essential supplement, and the packaging is clean and professional. Definitely a product I feel confident offering to my customers.

Potent and Gentle Vitamin C Boost

I really like American Health Ester-C® with Citrus Bioflavonoids! The 1,000 mg dose gives a strong vitamin C boost, and I haven’t experienced any stomach upset like I used to with other vitamin C brands. The added citrus bioflavonoids make it feel like an extra quality formula. Easy to take and great for daily immune support. Excellent value and highly recommend!

I switched to this Ester-C after reading it's gentler on the stomach, and I can honestly say it's made a huge difference. I no longer get the upset stomach I used to with regular vitamin C, especially when taking it on an empty stomach. I managed to get through the entire cold season without getting sick, which is a first for me. I'm so impressed that I've already convinced my sister to start taking it, too.

I switched to this Ester-C because regular vitamin C supplements always seemed to upset my stomach. This formula is much gentler, and I can take it on an empty stomach with no issues. I've managed to avoid the last few colds that went through my office, which I absolutely credit to this. It's a staple in my daily vitamin regimen now and I won't use anything else.

It’s especially good for: • Sensitive stomachs or GERD-prone individuals (though some still report irritation) • Daily immune boost and skin health • Those looking for gentle, long-lasting supplementation

The 1000 mg tablets are a potent dose for supporting immunity and overall health, and their vegetarian formulation is excellent. The tablet size is reasonable and easy to swallow.
