Do you need to supplement vitamin A every day

Vitamin A generally does not require additional daily supplementation, and healthy individuals can meet their needs through a balanced diet. Vitamin A supplementation should consider factors such as dietary intake, specific physiological stages, and symptoms of deficiency. Vitamin A is a fat soluble vitamin that can be stored in the liver. Long term excessive supplementation may cause poisoning. The recommended daily intake for an average adult is approximately 800 micrograms of retinol equivalent for males and 700 micrograms of retinol equivalent for females. Animal liver, egg yolks, dairy products and other foods are rich in vitamin A, and beta carotene in dark vegetables can also be converted into vitamin A in the body. Consuming animal liver 1-2 times a week or consuming 300 grams of dark vegetables daily can usually meet the demand. Pregnant women, lactating women, infants, and other special populations may need to follow medical advice for supplementation. Premature infants, patients with fat absorption disorders, and long-term vegetarians are at risk of deficiency and require monitoring of serum retinol levels. Symptoms such as night blindness, dry skin, and recurrent infections may indicate vitamin A deficiency, and short-term supplementation should be carried out under the guidance of a doctor.

In daily diet, alternate consumption of foods rich in vitamin A such as pork liver, carrots, spinach, broccoli, etc., to avoid long-term intake of single supplements. Combining oil and fat during cooking helps with the absorption of beta carotene, but high-temperature frying may damage the nutrients. If supplements are needed, it is recommended to choose multivitamin preparations and strictly control the dosage to not exceed the maximum tolerable daily intake of 3000 micrograms.
