A doctor has raised concerns about the uncontrolled use of vitamin D supplements, warning that excessive use could have adverse effects on bone health.

Suraj Kukadia emphasizes that, although vitamin D is essential for the body, taking it in large quantities can lead to serious problems such as weakening bones, kidney and heart damage.

The role of vitamin D in the body

Vitamin D helps regulate calcium and phosphate in the body, which are important for healthy bones, teeth, and muscles. Its deficiency can cause problems such as rickets in children and osteomalacia in adults.

The UK Health Organization (NHS) recommends taking it especially during autumn and winter, when sun exposure is lower.

The danger of excess

According to Dr. Kukadia, excessive use of vitamin D can increase the level of calcium in the blood (hypercalcemia). This condition, he says, can lead to serious consequences such as paradoxical weakening of the bones and damage to vital organs.

He emphasizes that supplements should only be taken under medical guidance and in accordance with recommended dosages.

What the NHS says

The British Health Service warns that taking too much vitamin D over a long period of time can lead to calcium accumulation in the body, which can damage the bones, kidneys and heart.

The recommended dose for adults is 10 micrograms per day, while exceeding 100 micrograms may be harmful. Different limits apply for children, infants, and other sensitive groups.

Health authorities emphasize that in case of uncertainty, it is necessary to consult a doctor before taking supplements.

Natural sources of vitamin D

Vitamin D can also be obtained from foods such as:

fatty fish (salmon, sardines, trout, herring, mackerel)

red meat

egg yolks

fortified foods (cereals and other products)

liver (with special care during pregnancy)

Experts also emphasize that, although the body cannot “overdose” on the sun, excessive exposure without protection increases the risk of skin damage and skin cancer. /GazetaExpress/
