Vitamin D: Benefits of taking daily supplements

Vitamin D supports strong bones, teeth, and muscle function by helping the body regulate the amount of calcium and phosphate you absorb. With a modern lifestyle, it's difficult to get the required amount of vitamin D your body needs, so it's advised that everyone considers taking vitamin D supplements.

They're especially important during autumn and winter months as the body requires sunlight to produce its own vitamin D, and it's difficult to top up to the required amount with food alone. An insufficient amount of vitamin D can lead to weak bones and conditions like rickets and osteomalacia.

How long does it take for vitamin D supplements to work?

It varies from person to person, but it's always best to prevent a vitamin D deficiency before it sets in - if you do think you have a deficiency, you should seek medical advice from your doctor. You should start to see the benefits after a few weeks.

Taking daily vitamin D supplements (following the recommended intake on the packaging) should be enough to support healthy bones and teeth, and you should never take more than recommended as it can be harmful.
