Fultium D3 is 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.
Fultium D3 works by increasing the amount of vitamin D in your body.
Vitamin D is an essential vitamin, one that helps ward off cancer, 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 possible. 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, it isn't always easy getting the full amounts of vitamin D from the sun, which is where diet and supplements come in.
Usually you only get around 10% of our vitamin D levels from your diet, with eggs, oily fish and fortified cereals all helping, but without some supplements, such as Fultium D3, you are likely to still be short.
In terms of which Fultium dose you’ll be prescribed, it depends on your circumstances. Doses like Fultium 800 IU (IU is the measurement of vitamin potency) are used to prevent low vitamin D levels from happening in the first place. It can also be used to maintain levels after treating low levels with higher dosages, as is the case with bone problems or hypothyroidism.
Fultium 3,200 IU can be used to treat the various conditions listed above, but it’s only available with a prescription for the first 12 weeks, after which, a new consultation will be needed. Fultium 20,000 IU capsules, drops and tablets are prescribed to treat these conditions for up to seven weeks, at one or two doses per week. You will then likely be advised to use the smaller dosages to maintain your vitamin D levels.
How we source info.
When we present you with stats, data, opinion or a consensus, we’ll tell you where this came from. And we’ll only present data as clinically reliable if it’s come from a reputable source, such as a state or government-funded health body, a peer-reviewed medical journal, or a recognised analytics or data body.

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.
The length of time it takes for Fultium D3 to work depends on what you’re using it. If you are deficient in vitamin D, it can take a few weeks of using Fultium D3 for your levels to increase to an ideal level. Whereas if you are simply using Fultium D3 to maintain good levels of vitamin D and prevent deficiency issues, then the effects may be less noticeable, but it will be working to keep your body working well in the background.
Fultium D3 should usually be safe to use unless you take too much of it. So it’s important to use it as prescribed by your clinician. It can be dangerous to take too much vitamin D, so if you think that you have, then you should contact your doctor for advice.
Whereas if you have simply missed a dose, then don’t worry, this shouldn’t cause you any problems. Just take your next dose as you normally would, at your normal time.
