Retinyl Acetate Side Effects

Retinyl acetate (retinol acetate, vitamin A acetate) is a natural form of vitamin A which is the acetateester of retinol. It has potential antineoplastic and chemopreventive activities. Though it’s considered safe, some are convinced it has potentially dangerous health effects.

What Is Retinyl acetate?

Vitamin A Acetate is a microencapsulated light yellow powder used in solid, liquid drinks, water-based food and ordinary food fortification, but also can be used as tablet and hard capsules. This product is Vitamin A palmitate oil emulsion that after certain vectors is spray-dried to form powder particles.

Possible Side Effects of Retinyl acetate

Although Retinyl acetate generally regarded as a very safe and effective supplement, there can be some minor side effects. The side effects may:

  • Difficulty breathing
  • Swelling of face
  • Discoloration of urine
  • Swelling of lips & tongue
  • Skin irritation

GRAS Affirmation: Yes

Generally recognized as safe (GRAS) is an American Food and Drug Administration (FDA) designation that a chemical or substance added to food is considered safe by experts, and so is exempted from the usual Federal Food, Drug, and Cosmetic Act (FFDCA) food additive tolerance requirements. Retinyl acetate is considered safe.

Suggested Dosage


Special Populations Precaution

There is a lot of concern about diet and nutrition for these population, like Newborns, children, pregnant, sensitive to Retinyl acetate populations. Better consult to your doctor if you would like to intake Retinyl acetate.
