I have taken 3-5 grams of vit C the last years, ascorbic acid; capsules and powder without any or little fillers

Tried all of them, except for ester C as I dont want the calcium ascorbate. It is usually expensive and contain fillers and binders I stay away from. Like Dicalcium phosphate.

"• Ester-C®: Ester-C® contains mainly calcium ascorbate, but also contains small amounts of the vitamin C metabolites dehydroascorbic acid (oxidized ascorbic acid), calcium threonate, and trace levels of xylonate and lyxonate. In their literature, the manufacturers state that the metabolites, especially threonate, increase the bio-availability of the vitamin C in this product and that they have performed a study in humans demonstrating the increased bioavailability of vitamin C in Ester-C®. This study has not been published in a peer-reviewed journal. A small published study of vitamin C bioavailability in 8 women and 1 man found no difference between Ester-C® and commercially available ascorbic acid tablets with respect to the absorption and excretion of vitamin C.

• Vitamin C with bioflavonoids: Bioflavonoids are a class of water-soluble plant pigments. Vitamin C-rich fruits and vegetables, especially citrus fruits, are often rich sources of bioflavonoids as well. The effect of bioflavonoids on the bioavailability of ascorbic acid has been examined in two small published studies. In one study synthetic ascorbic acid given in a natural citrus extract containing bioflavonoids (in the ratio of bioflavonoids to ascorbic acid of 4:1), proteins, and carbohydrates, was more slowly absorbed and 35% more bioavailable than synthetic ascorbic acid alone, based on plasma levels of ascorbate over time and 24-hour urinary excretion of ascorbate. In the other study, there was no difference in the bio-availability of 500 mg of synthetic ascorbic acid and that of a commercially available vitamin C preparation with added bioflavonoids, where the ratio of bioflavonoids to ascorbic acid was 0.05:1."

Magnesium ascorbate is a better option than the Ester C, IMO
