Popular questions
Is ascorbic acid bad for you?
No—ascorbic acid (vitamin C) is considered safe at typical food levels and is essential for health; it’s GRAS in the U.S. and approved in the EU. Very high supplemental doses can cause gastrointestinal upset and, in susceptible people, increase kidney stone risk.
Can dogs have ascorbic acid?
Yes, small amounts in foods are safe, but dogs synthesize their own vitamin C and usually don’t need supplements. High doses may cause diarrhea, so consult a veterinarian before supplementing.
What is ascorbic acid made from?
Commercial ascorbic acid is typically made from glucose (often derived from corn, wheat, or cassava) that’s converted via microbial fermentation and chemical steps into L‑ascorbic acid.
How is ascorbic acid made?
Industrially, D‑glucose is converted to 2‑keto‑L‑gulonic acid by fermentation (or via the older Reichstein process: glucose → sorbitol → L‑sorbose → 2‑KGA) and then chemically cyclized to ascorbic acid. Modern methods use two-step fermentation to improve efficiency.
Is ascorbic acid the same as citric acid?
No—ascorbic acid (E300) is vitamin C and an antioxidant, while citric acid (E330) is a different compound mainly used as an acidulant and does not provide vitamin C.
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.
