Hello,

Welcome to icliniq.com.

I understand your concern.

Vitamin A is not synthesized by our body, so we need to obtain it from external sources, including both plant and animal origins. Vegetables that are yellow, red, and green are rich sources of this vitamin in the form of beta-carotene. Animal sources, such as beef and cod liver oil, mostly contain vitamin A as retinol or retinyl esters. Vitamin A is crucial for maintaining good vision, a healthy reproductive system, and a robust immune system, among other functions. The daily requirement for all age groups is measured in micrograms. The demand for toddlers and breastfeeding individuals increases.

I hope I have answered your questions.

Thank you.
