What is Fultium D3?

It’s a form of vitamin D that’s also known as colecalciferol. Vitamin D comes in various forms, but the main two are vitamin D2 and vitamin D3. For now, all you need to know is that vitamin D3 is the easier form to absorb and is the more popular of the two for preventing deficiency, keeping levels of vitamin D high, along with your mood.

Can I buy Fultium D3 over the counter?

No. Fultium D3 is available on prescription only, so you’ll need to have a consultation with a clinician to assess if it’s safe for you to use.

Fultium D3 may cause side effects, and it can interact with other medications, so it’s important that a clinician takes into account any susceptibility to side effects that you may have, or any other treatments that you may be using, before prescribing this supplement.

What are the benefits of taking Fultium daily vitamin D products?

Low vitamin D can cause a variety of problems, including low mood and bone problems.[1] It can also heighten your risk of heart disease.[2] What’s more, people in countries like the UK, where the sun is particularly weak in winter, are much more likely to have low vitamin D. Taking Fultium D3 daily is a simple way of keeping yourself healthy in those dark winter months.

What you need to know about Fultium D3

What you need to know about Fultium capsules, drops and tablets

Vitamin D is an essential vitamin, one that helps ward off cancer,[3] heart disease, diabetes, depression and osteoporosis. Unlike most other vitamins and minerals, we get the vast majority of it with minimum effort, by exposing ourselves to the sun. Unfortunately, that isn’t always as simple as it sounds. What’s more, the darker your skin, the more likely you’ll have low vitamin D levels.

For areas where the days are short over the winter, such as the UK, it isn't always easy getting the full amounts of vitamin D from the sun, which is where diet and supplements come in.

Usually we only get around 10% of our vitamin D levels from our diet, with eggs, oily fish and fortified cereals all helping, but without some supplements, such as Fultium D3, we are likely to still be short.

How to take Fultium D3

Instructions for taking Fultium are very simple, but will depend on the strength and form that it comes in. For example, stronger doses can be taken once or twice a week for seven weeks, while preventative dosages are taken daily.

There are also tablets, capsules and drops to choose from. Capsules and tablets should be swallowed whole with water, and you’ll need to follow your prescriber’s instructions for whether this includes one or more for each dosage. Drops should be dispensed on a spoon after gently shaking the bottle. Like tablets and capsules, the amount of drops will depend on the age of the person taking it and your prescriber’s instructions.

Food sources of vitamin D


You should always read the patient information leaflet that comes with your treatment before you take Fultium D3.

Who shouldn't take Fultium D3?

Vitamin D is very well tolerated by almost all who take it, but that does not mean there are no risks involved. It’s therefore important that you know what these are before taking it, particularly relating to pre existing conditions and other medications.

If any of the following apply to you, you should not take Fultium D3: allergies to any of its ingredients, high levels of vitamin D in the blood, high levels of vitamin D in the urine, severe kidney disorders or kidney stones.

Your prescribing clinician will also need to know if any of the following apply to you and might suggest a different treatment: kidney disease, kidney issues, heart disease or sarcoidosis.
