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 blood urea nitrogen?
Blood urea nitrogen (BUN) measures the amount of nitrogen in your blood that comes from urea (carbamide, E927b), a protein-metabolism waste product; it’s commonly used to assess kidney function and hydration.
What is urea cream?
A topical product containing urea (carbamide) typically 2–40% that hydrates skin as a humectant and, at higher strengths, softens and exfoliates thick, dry, or scaly skin as a keratolytic.
What is urea nitrogen?
Urea nitrogen is the nitrogen portion of urea measured in clinical tests like BUN, indicating how much urea-derived nitrogen is in the blood.
What is urea in def?
Urea (carbamide, E927b) is a simple organic compound, CO(NH2)2, the main nitrogenous waste in humans, made synthetically and used in fertilizers, skin products, and as a food processing aid/yeast nutrient.
What does urea do for skin?
It draws water into the outer skin layers to moisturize (humectant) and, at higher concentrations, breaks down hardened keratin to smooth rough or callused skin (keratolytic).
