What is the difference between liquid and capsule vitamin D?

There are many types of vitamin D supplements available to help manage vitamin D insufficiency and these have been designed to cater for a variety of individuals and their diverse needs. Vitamin D in a liquid and a capsule contain the same form of this important nutrient, vitamin D3, which is the type of vitamin D that the body produces naturally.

The difference between liquids and capsules lies in their physical format, how they are taken in by the body and their daily dose. Whether you take a liquid or capsule vitamin D supplement is a personal preference. Outlined below are some of the benefits of these formats and what type of individual they may suit.

Liquid vitamin D

Liquid vitamin D3 products may be suitable for those who:

  • Have difficulty swallowing capsules including older individuals.
  • Are already taking several pills and do not want to add to this.
  • Would like something they can mix with other liquids.
  • Are children ‐ Liquid vitamin D supplements are preferable for small children as they are easy to dispense and do not pose a choking risk. Ostelin’s Kids Vitamin D3 Liquid has a pleasant natural strawberry flavour, which makes it enjoyable for children to take. It is also free from added sugar, artificial colours, sweeteners or flavours.

Vitamin D capsules

Vitamin D capsules usually provide vitamin D in the form of vitamin D3 via a soft gelatin capsule. Ostelin Vitamin D3 1000IU capsules are suitable for those who:

  • Want a simple solution for their vitamin D needs.
  • Have no trouble swallowing small capsules.
  • Want a high strength vitamin D in a convenient one‐a‐day dose.

Always read the label. Follow the directions for use. Vitamin supplements should not replace a balanced diet.
