Calcium Ascorbate
Also known as: E302, calcium-L-ascorbate
Calcium ascorbate is FDA GRAS and EFSA-evaluated; in 2015 EFSA concluded it is not necessary to set a numerical ADI for ascorbic acid and its salts at typical intake levels, and there is no genotoxicity concern.
What it is
Calcium ascorbate (E302) is the calcium salt of ascorbic acid (vitamin C), used as an antioxidant.
Antioxidant; vitamin C source; pH regulator.
Why it's flagged
- very high doses can cause GI symptoms similar to vitamin C overdose
