Ester-C Vitamin C Supplements

Ester-C is a patented, pH-neutral form of vitamin C designed to be gentler on the stomach than traditional ascorbic acid — a meaningful difference for anyone who has experienced acidity or digestive upset from ordinary vitamin C tablets. It's the type of daily immune support people reach for during cold and flu season, when run down, or simply to maintain year-round wellness.

What sets Ester-C apart is how the body handles it. Because it's non-acidic, it's easier on sensitive stomachs, and studies behind the formula point to vitamin C staying in white blood cells longer than with standard ascorbic acid. That combination of tolerability and lasting support is why it's a popular once-daily choice rather than something you need to dose repeatedly throughout the day.

In this collection you'll find the Ester-C Immune Supplement in 500 mg tablets, a straightforward strength that works well for everyday supplementation. One tablet a day is a common regimen, though many people choose their dose based on individual needs and any guidance from their pharmacist or physician. Vitamin C also supports collagen formation and acts as an antioxidant, so its benefits extend beyond immune health to skin and connective tissue.

Ester-C is suitable for adults looking for a stomach-friendly vitamin C they can take consistently. If you're managing dosing for a household or a care setting, the 500 mg tablet format makes portioning and tracking simple. As with any supplement, keep it stored dry and away from heat, and check the label for any allergen or dietary considerations before adding it to a routine.
