Buy Aciferol online and get the sunshine pill on subscription

Vitamin D is one of the essential substances the body needs to function. While we get most of what we need from the sun, in the winter months it sometimes just doesn’t give us what we need.[1] Aciferol can plug the gap. Think of it as sunshine in a bottle.

When you subscribe to EveAdam, you can get your treatment delivered to your door, as and when you need it, so even if the sun lets you down, we have you covered.

Aciferol tablets and what they are used for

Aciferol tablets contain the substance colecalciferol, a form of vitamin D that the body finds easy to process. It’s available in tablets, capsules and liquids. The main thing you need to know (more technical details can be found below), is that it can be used to stop vitamin D levels from dropping if you do not get enough sunlight on the skin. It can be prescribed as a preventative measure or a treatment, depending on the dosage.

Can I buy Aciferol over the counter?

Yes (and no), as this will depend on the dosage of the treatment. For daily maintenance doses, you can buy Aciferol over the counter, but for treatments relating to severe vitamin D deficiencies, you will need a prescription.

So what does Aciferol do?

Put simply, it raises or maintains the level of vitamin D in the body. Things get a little more complicated when it comes to the details of the treatment. Small doses, such as Aciferol D3 400 IU, are taken daily to maintain vitamin D levels, while stronger doses, such as Aciferol D3 20,000 IU products, are prescribed for severe cases. If in doubt, speak to your prescribing clinician about the best treatment for you.

What you need to know about Aciferol tablets, capsules and liquids

The first question we need to answer is “what is vitamin D?” In short, it’s an essential nutrient that we need to maintain healthy bones, teeth and muscles. Without the right levels of vitamin D, we run the risk of cancer and bone deformities.

Aciferol D3 is a form of vitamin D that the body finds easy to process quickly. This is important for both preventing a lack of vitamin D occurring and treating conditions that are affected by it.
