Solgar, Ester-C Plus®, Vitamin C
Verified purchase
Honestly, this Vitamin C is a game changer because it never upsets my stomach—finally, a C I can take on an empty stomach without that acidic burn! I swear I feel a noticeable difference; it really seems to keep my immune system strong and I haven't gotten those usual seasonal bugs. Plus, the capsules are super easy to swallow and it's a total no-brainer to take every day.

Premium Ester-C
Verified purchase
Ester-C is a patented, unique form of Vitamin C (Calcium Ascorbate) that is widely regarded as a "premium" version of the standard supplement. It is specifically designed to overcome the two biggest issues with regular Vitamin C: stomach irritation and short-lived effectiveness. Standard Vitamin C is Ascorbic Acid, which is naturally acidic. Ester-C is created through a process that neutralizes the acid, making it pH-neutral. It also contains Vitamin C metabolites (like threonate), which research suggests helps the body absorb the vitamin more efficiently.

Excellent quality, Solgar, Ester-C Plus®, Vitamin C
Verified purchase
This vitamin C, as ascorbic acid, ester-C, is a unique vitamin C that is not acidic; gentle on sensitive stomachs. Since I started taking this vitamin C, I have no problem with stomach pain, heartburn, and bloating. My energy has increased! When I feel a cold coming on, I immediately take this supplement, but double the dose, and the cold stops immediately. It really works. In fact, I have used many Solgar products and they have all proven to be excellent quality products.

I have been taking Solgar Ester-C® 500 mg for several weeks and I’m very pleased with it. The non-acidic form of vitamin C is gentle on my stomach, which is a big plus because many other ascorbic acid formulas used to irritate me. It also appears to support my immune system and general wellbeing — I feel less fatigued and recover quicker after minor colds. See for example users reporting improved skin tone and stronger immunity. The product is also free of gluten, dairy, and soy, and comes in a vegetarian-friendly capsule.

I’ve been using Solgar’s Ester-C Plus for a few months now and I’m extremely pleased with the results. The 500mg dosage is perfect for supporting my immune system, especially during the colder months. I love that it’s gentle on my stomach and doesn’t cause any irritation like some other Vitamin C supplements I’ve tried. The capsules are easy to swallow, and I appreciate the fact that they’re made with high-quality ingredients. Definitely a staple in my daily routine!

This Ester-C is the only vitamin C that doesn't upset my sensitive stomach. I've been taking it daily for months and have managed to avoid every cold that's gone through my office. The vegetable capsules are easy to swallow and don't have any unpleasant aftertaste. It's a reliable, gentle product that I feel really works.

I started taking this vitamin C at the first sign of a scratchy throat, and I'm convinced it helped me avoid a full-blown cold. The Ester-C is gentle on my stomach, unlike some other brands that have caused discomfort. The capsules are a nice, small size and are very easy to swallow. It's become a trusted part of my wellness routine, especially during cold and flu season.
