Popular questions
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).
What is d alpha tocopherol?
It’s the natural stereoisomer of vitamin E (RRR‑α‑tocopherol, E307), typically derived from vegetable oils and used as an antioxidant and nutrient in foods.
Is d alpha tocopherol natural?
Yes—“d‑” indicates the naturally occurring RRR‑α‑tocopherol, usually sourced from plant oils; the synthetic form is labeled “dl‑” (all‑rac‑α‑tocopherol).
What is d-alpha tocopherol?
It’s the natural form of vitamin E (RRR‑α‑tocopherol, E307), the most biologically active isomer and commonly used as an antioxidant in foods.
Is d alpha tocopherol synthetic?
No; the “d‑” form is natural, while the synthetic version is the racemic “dl‑” (all‑rac) α‑tocopherol.
What is d alpha tocopherol acetate?
It’s the acetate ester of d‑α‑tocopherol used for improved stability in foods and supplements; the body converts it to active α‑tocopherol.
