Should you take vitamin D daily? Here's what experts say

Taking vitamin D every day can support bone health, muscle function and balance, particularly for people with low vitamin D levels, but experts caution that unnecessary supplementation or excessive doses may do more harm than good.

Vitamin D helps the body absorb calcium and phosphorus, two minerals essential for maintaining strong bones and healthy teeth.

People who are deficient may experience improved bone strength, better oral health and enhanced muscle function after taking daily supplements.

Health experts say correcting a vitamin D deficiency may also reduce muscle weakness and improve balance, potentially lowering the risk of falls and fractures.

However, studies suggest that people with normal vitamin D levels are unlikely to gain additional bone health benefits from taking extra supplements.

Experts also warn that excessive vitamin D intake can cause hypercalcemia — a condition marked by high calcium levels in the blood.

Symptoms may include nausea, vomiting, abdominal pain, dehydration and confusion, while prolonged cases can lead to kidney damage and heart rhythm problems.

A simple blood test can determine whether someone has a vitamin D deficiency. Adults under 70 generally require 600 IU daily, while those over 70 are advised to consume 800 IU.

Doctors recommend discussing supplementation with a healthcare provider and monitoring vitamin D and calcium levels, especially when taking supplements regularly.
