Vitamin A

Vitamin A

Vitamin A plays an important role in eye health, the immune system, and cell growth. Vitamin A supplements can be used in the treatment of measles and vitamin A deficiencies, including xerophthalmia .

Naturally, the need for vitamin A can be met by consuming foods rich in this vitamin, such as milk, beef liver , cheese, yogurt , eggs, mangoes, spinach, carrots or fish oil.

To prevent vitamin A deficiency, the Ministry of Health of the Republic of Indonesia conducts a program of routinely providing vitamin A supplements to toddlers.

Two kinds of vitamin A capsules are given, namely blue capsules for babies aged 6–11 months, and red capsules for children aged 1–5 years. Vitamin A red capsules can also be given to mothers who have just given birth (childbirth).

How to Take Vitamin A Properly

Be sure to take your vitamin A supplement according to the directions on the package. If necessary, discuss with your doctor to find out the right dosage according to your condition. Do not exceed the recommended dose to avoid side effects.

Keep in mind that vitamin and mineral supplements are consumed to meet the body's need for vitamins and minerals, especially when the intake of vitamins and minerals from food alone is insufficient.

Vitamin A supplements should be taken with food to make them more easily absorbed by the body. Swallow the vitamin A tablets or capsules whole. Do not split, chew, or grind the supplement.

If you forget to take vitamin A, take this supplement immediately if it is not close to the next consumption schedule. If it is close, ignore the missed dose and do not double the next dose.

Store vitamin A tablets or capsules at room temperature, in a dry place, and avoid heat and direct sunlight. Keep this supplement out of reach of children.
