Why is Synbio called the sunshine pill?

We should get most of our vitamin D from the sun by simply exposing our skin to it. Unfortunately for people in the UK, and other parts of the world where the sun is weak or extremely shy in the winter, that isn’t always easy.

This is where vitamin D supplements come in. They provide that precious sunshine in pill form, hence the name the sunshine pill, and its effects can have a major impact on mood and energy levels.

Why do I need to take Synbio vitamins?

It’s likely that if you live in the UK during the winter months your vitamin D levels are going to drop significantly without taking a supplement. In fact, it’s estimated that a whopping one billion people worldwide are vitamin D deficient.[1]

Vitamin D is an essential vitamin. Its primary function is to keep your bones, teeth and muscles healthy, but it also affects other things too, from your mood to your energy levels. In severe cases, it can lead to brittle bones or deformities. Taking a treatment can help in these circumstances, but the supplement products will help prevent serious problems in the first place. As they say, prevention is better than the cure.

Why should I buy Synbio online?

You will need a prescription to buy the treatment dosages of vitamin D as their use will need monitoring. But worry not, that only means filling in a short questionnaire so that one of our UK registered clinicians will be able to offer a range of the most suitable products. You’ll get your first package the next working day.

For supplements such as Synbio, you can buy them from your local pharmacist, but this means remembering to keep a steady supply going as they’re only as effective as your memory to take them. This is one of the most important advantages to buying online, it’s one less thing to worry about.

What should I do if I take too much?

What are the most common side effects of Synbio?

Side effects of Synbio are uncommon and usually relate to having high levels of calcium in the body when they do occur. Calcium levels are directly related to the level of vitamin D you’re taking, so as long as you’re not taking in too much vitamin D for your needs, it’s unlikely you’ll experience any issues.

The most common side effects are hypercalciuria (too much calcium in the urine) and hypercalcaemia (too much calcium in the blood). The symptoms of hypercalciuria include urinary tract infections, kidney stones, urination pain and unusually frequent urination.

Are there different types of vitamin D?

Broadly speaking, there are two types of vitamin D, vitamin D2 and vitamin D3. So what are the differences?

Vitamin D3 is the more common form used in supplements and treatments. This is because D3 is better processed in the body. It’s also the form that’s used to fortify (added to) food stuff, such as cereals and margarines.
