Popular questions
Is ascorbyl palmitate safe?
Yes—it's approved as a food antioxidant in the EU, U.S., Canada, Australia, and New Zealand and is considered safe at permitted levels. The body breaks it down into vitamin C (ascorbic acid) and palmitic acid; high supplemental intakes may occasionally cause mild stomach upset.
What is ascorbyl palmitate in supplements?
A fat‑soluble form of vitamin C used either as the active vitamin C or to protect oils and softgels from oxidation. It’s hydrolyzed to ascorbic acid and palmitic acid, so its vitamin C activity is similar to regular vitamin C but it’s favored for oil‑based formulations.
What is ascorbyl palmitate made from?
It’s the ester of L‑ascorbic acid (vitamin C) and palmitic acid, typically derived from palm oil or other fats. It’s produced by chemical or enzymatic esterification; sources can be plant, animal, microbiological, or synthetic.
Ascorbyl palmitate what is it?
Ascorbyl palmitate (E304i) is a fat‑soluble ester of vitamin C used as an antioxidant in foods, especially those rich in fats. It helps slow oxidation and rancidity and can also act as a source of vitamin C.
What is ascorbyl palmitate used for?
Primarily as an antioxidant (E304) to prevent rancidity and preserve flavor and color in foods like oils, margarines, snacks, and baked goods. It’s also used in supplements to stabilize oil‑based ingredients and sometimes as a vitamin C source.
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.
