Health Information

Some frequently asked questions about Ester-C

Q What is Ester-C® and how does it differ from ordinary Vitamin C?
A When Vitamin C is metabolised in the body, it breaks down into secondary compounds called metabolites. Scientific studies1,2 show that Threonic Acid*, one of these metabolites, is responsible for the differences between ordinary Vitamin C and Ester-C®, including its high bioavailability its ability to provide a full 24 hours of immune support, compared with the 2 hours of ordinary Vitamin C.

*Threonic Acid is standardised in Ester-C® as Calcium Threonate.

Q Why is Ester-C® described as “stomachfriendly”?
A Ordinary Vitamin C is acidic (its scientific name is “ascorbic acid”), which means that it may cause gastro-intestinal irritation in some people. The unique water-based process that Ester-C® undergoes, however, makes it non-acidic. This means that it can be gentler on the stomach than ordinary Vitamin C.

Q What are Citrus Bioflavonoids, and why does this product contain them?
A Bioflavonoids are a family of compounds found in plants, which can have a wide range of health benefits. The Citrus Bioflavonoids in Nutra-Life Ester-C 1500mg + Bioflavonoids help to increase the absorption and effect of the Vitamin C, and provide extra antioxidant activity. They also help to maintain strong, healthy capillary walls.

Q Why is Vitamin D3 important for a healthy immune system?
A Vitamin D3 is an essential fat-soluble vitamin produced in the body when exposed to sunlight. Vitamin D3 plays an important role in activating special immune cells called T-cells and helps to support overall immunity. Low levels of vitamin D3 can lead to infection.
