Serious negative effects may result from a vitamin A excess. Usually, preparations rather than diet are to blame.

The liver is where the body accumulates fat-soluble vitamin A, also known as retinol. When more vitamin A is taken than is necessary, it cannot be easily eliminated; instead, it builds up. Consequently, grievances may surface.

Vitamin A can be found in many common foods, both plant and animal-based. But unless liver consumption is a regular occurrence for the sick person, a vitamin A overdose rarely warrants concern based only on food. Plant-based foods include beta-carotene, also known as provitamin A, which the body can convert into vitamin A. As a result, significant amounts of this substance are safe to consume.

How much vitamin A does the body require each day?

Experts typically advise against taking dietary supplements containing vitamin A unless absolutely necessary, due to the good supply situation that exists in all nations. Extended usage may quickly result in an overdose and an overstock. Next, experts discuss hypervitaminosis.

If people afflicted take vitamin A-containing medications on a daily basis, such as retinoic acid (isotretinoin), which is the active ingredient in medications used to treat severe acne, there may also be a danger of overdosing.
A doctor should be consulted by anyone who observes symptoms of an overdose or adverse consequences.

Potential adverse effects of a vitamin A overdose

A vitamin A excess can have a number of negative effects. Symptoms of acute vitamin A toxicity include the following:

Head Pain
vomiting and nausea
vision issues
faintness
itchiness
Elevation of intracranial pressure

Take large amounts of vitamin A over a short period of time to avoid acute vitamin A poisoning. Then, a few hours later, adverse consequences may manifest.

Side effects can also arise from a prolonged (chronic) excess of vitamin A; this is typically the consequence of consuming vitamin A-containing dietary supplements over an extended period of time. Among the possible indicators of this are:

diminished appetite
arid skin
rough skin that cracks
Hair loss ripped mouth corners (rhagades in the mouth corners)
Gallstones with enlarged liver
aches in the muscles and joints
Fecting (in females) bleeding during menstruation
bone ache
