Vitamin A acetate is a synthetic form of vitamin A that is commonly used in dietary supplements and fortified foods. However, it's important to note that vitamin A deficiency is typically associated with a lack of dietary intake of natural forms of vitamin A, such as retinol or beta-carotene, rather than a deficiency specific to vitamin A acetate.

That said, the symptoms of vitamin A deficiency, regardless of the form, can include:

Night blindness: This is often one of the first signs of vitamin A deficiency. It refers to difficulty seeing in low-light conditions or the inability to adjust to darkness.

Dry eyes: Insufficient vitamin A can lead to dryness of the eyes, causing discomfort, redness, and an increased risk of eye infections.

Skin problems: Vitamin A plays a crucial role in maintaining healthy skin. Deficiency may lead to dry, rough, and scaly skin, as well as an increased susceptibility to various skin conditions.

Impaired immune function: Vitamin A is necessary for a well-functioning immune system. Inadequate intake can weaken the immune response, making individuals more prone to infections, especially respiratory infections.

Delayed growth and development: In children, a deficiency in vitamin A can hinder growth and development, leading to stunted growth and delayed bone development.

Poor wound healing: Vitamin A plays a vital role in tissue repair and wound healing. Deficiency may impair the body's ability to heal wounds properly.

Changes in hair and nails: Vitamin A deficiency can result in dry, brittle hair and nails, and it may also lead to increased hair loss.

It's important to note that these symptoms can be caused by various factors, and they do not solely indicate a vitamin A acetate deficiency. If you suspect a vitamin deficiency, it is advisable to consult with a healthcare professional who can evaluate your symptoms, perform appropriate tests, and provide the necessary guidance and treatment.
