What is Vitabiotics Ultra Vitamin D?

Vitabiotics Ultra Vitamin D is a vitamin D supplement which contains 25 micrograms of Vitamin D (cholecalciferol).

Vitabiotics Ultra Vitamin D is available as tablets which replenish the amount of vitamin D in the body, to prevent or treat a vitamin D deficiency. The special formulation of Ultra vitamin D gives you a convenient and consistent dose of this much-needed vitamin.

Vitabiotics Ultra Vitamin D tablets are halal certified, made from vegetarian products.

You can buy Vitabiotics Ultra Vitamin D tablets online from Prescription Doctor's convenient online pharmacy. Our pharmacy can dispatch your item the same day via a next-day delivery when you order before 3pm Monday to Friday.

What does vitamin D do?

Vitamin D regulates the amounts of the minerals, calcium and phosphate in your body:

  • It helps to absorb and store calcium in the skeletal tissue and regulates the cells responsible for the formation and maintenance of bones.
  • It recycles calcium in the kidneys, preventing it from being excreted and helps the bones to reabsorb it.
  • It helps intestines to absorb the calcium present in food and supplements.

Vitamin D is not only important for keeping bones healthy, but also helps to maintain your muscles.

How much Vitamin D do I need?

According to the NHS, a daily intake of 10 micrograms of Vitamin D is recommended for everyone, including breastfeeding and pregnant women.

Children under the age of 1 should be given a daily supplement containing 8.5 to 10 micrograms of Vitamin D.

Children aged from 1 to 4 years should be given 10-microgram supplement of Vitamin D per day.

Who should take Vitamin D?

Public Health England recommends that everyone should take a daily supplement of vitamin D in the months from October to March as the sunlight is not enough. People who are at greater risk of developing the deficiency are

  • People who do not have enough exposure to the sun and spend most of the time indoors
  • Dark-skinned people
  • Vegetarians
  • Those who cover their skin from sunshine

If you are unsure whether you are at risk of developing a vitamin D deficiency, speak to your doctor. They will be able to discuss with you your risk, as well as preventive measures to prevent you from developing a vitamin D deficiency.

How do Vitabiotics Ultra Vitamin D works?

Vitamin D plays an important role in keeping bones, teeth and muscles healthy by increasing the absorption of calcium. Vitamin D is produced from cholesterol naturally when the skin is exposed to ultraviolet B (UVB) rays from the sun. There is not enough sunlight in the autumn and winter to produce the required vitamin D.

While vitamin D is present in dietary sources such as oily fish, eggs and fortified cereals or mushrooms, however, the daily requirements cannot be met through food alone. Most of the vitamin D required by the body is acquired by exposing the skin to the sun.

Vitabiotics Ultra Vitamin D contains cholecalciferol (Vitamin D³). It simply increases the amount of Vitamin D in our body to the optimum amount.

How do I take Vitabiotics Ultra Vitamin D?

Take one Vitabiotics Ultra Vitamin D tablet once a day with a glass of water. The tablets can be taken with or without a meal. You may find it easier to remember when to take your supplements if you take them with breakfast and make it a part of your daily routine.

Do not crush or chew the tablet.

If you have difficulty swallowing tablets, speak to your doctor or a pharmacist about alternative formulations.

When should I take vitamin D supplements?

Vitamin D supplements can be taken at any time of the day. To help you remember when to take vitamin D supplements, try working them into your routine, such as taking them with breakfast.

Information on when to take vitamin D supplements can be found on the label or the accompanying leaflet.

Your doctor may advise you to take vitamin D supplements at a specific time, if you are taking other medicines.
