Popular questions
Is sodium ascorbate vitamin c?
Yes—sodium ascorbate is the sodium salt of ascorbic acid (vitamin C) and provides vitamin C, with no proven bioavailability advantage over other forms; it also contributes some sodium.
What is sodium ascorbate used for?
As a food additive (E301) it acts as an antioxidant and acidity regulator, helping prevent oxidation and maintain color (e.g., in meats and beverages), and it’s also used to fortify foods or as a vitamin C supplement.
How to make sodium ascorbate?
It’s produced by neutralizing L-ascorbic acid with a sodium base (commonly sodium bicarbonate or sodium carbonate) and then drying; food-grade production is controlled for purity and is not recommended to replicate at home.
How to take sodium ascorbate?
Follow the product label, typically taken with water or food; don’t exceed about 2,000 mg/day of vitamin C from all sources unless advised, and account for the added sodium.
Is sodium ascorbate safe?
Yes—E301 is approved in the EU, USA, and Australia/New Zealand and is generally recognized as safe at typical food and supplement levels; high intakes may cause gastrointestinal upset, increase sodium intake, and may not suit people prone to kidney stones or on sodium-restricted diets.
Is calcium ascorbate bad for you?
No—at the small amounts used in foods it isn’t considered harmful and can provide vitamin C (and a little calcium). Very high supplemental intakes may cause stomach upset, and people prone to kidney stones or with iron overload should be cautious with high vitamin C.
What is calcium ascorbate made from?
It’s the calcium salt of ascorbic acid (vitamin C). Industrially, ascorbic acid is made by fermenting plant-derived glucose, then neutralized with a calcium source (e.g., calcium carbonate or hydroxide) to form calcium ascorbate.
Is calcium ascorbate safe?
Yes—it's approved in the EU, US, and Australia/New Zealand and is generally recognized as safe at normal food-use levels. Excessive supplemental doses may cause gastrointestinal upset.
Is calcium ascorbate synthetic?
Usually yes: it's produced via microbial fermentation of sugars followed by chemical neutralization with calcium, rather than being extracted directly from plants.
What is calcium ascorbate used for?
It’s used as an antioxidant to slow oxidation and browning, helping preserve flavor and color (e.g., in beverages, fresh-cut produce, and meats), and to fortify foods with vitamin C (and some calcium).
