Frequently Asked Questions

What makes Ester-C different from regular vitamin C?

Ester-C (calcium ascorbate) is buffered to be pH neutral — making it non-acidic and much gentler on the stomach than ascorbic acid. It also contains naturally occurring vitamin C metabolites that help retain it in immune cells up to 4 times longer than standard vitamin C, providing sustained immune support.

Is Ester-C better absorbed than regular vitamin C?

Clinical studies show Ester-C is retained in white blood cells significantly longer than ascorbic acid, which supports sustained immune function. For stomach-sensitive individuals, the non-acidic form is often better tolerated, making consistent supplementation easier.

Who should consider Ester-C over regular vitamin C?

Ester-C is ideal for people with sensitive stomachs who experience nausea or heartburn from regular vitamin C, those wanting sustained immune support, and anyone who finds high-dose vitamin C causes digestive discomfort.

How much Ester-C should I take?

The typical dose is 500mg to 1000mg per day. During illness or increased immune demand, higher doses may be used short-term. Vitamin C is water-soluble and excess is excreted, making toxicity unlikely at standard doses.

Is Solgar Ester-C Plus suitable for vegetarians?

Yes. Solgar Ester-C Plus 500mg capsules are made from vegetable cellulose and are suitable for vegetarians and vegans.
