Comparing E304I - Ascorbyl palmitate vs E309 - Delta-tocopherol

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.
