Synbio is vitamin D in capsule, oral solution or liquid form. A synthetic version of vitamin D3 called colecalciferol, it is used to treat serious health conditions and prevent deficiencies from occurring.
We should get most of our vitamin D from the sun by simply exposing our skin to it. Unfortunately for people in parts of the world where the sun is weak or absent in the winter, that isn’t always easy.
This is where vitamin D supplements like Synbio 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.
A severe lack of vitamin D over a prolonged period reduces the amount of calcium absorbed by the body. This, along with other factors such as low dietary calcium, leads to low density bones, known as osteoporosis.
Taking a Synbio maintenance dose prevents severe deficiencies from occurring, but the benefits of taking vitamin D supplements don’t end there. Less severe deficiencies are associated with low mood, fatigue, impaired immunity and a heightened risk of some cancers. It also keeps bones, teeth and muscles healthy.
There are a few different strengths of Synbio to choose from. At the stronger end there are 800 IU liquids and capsules. Drops are 100 IU but you can take four or eight drops for each dosage. The smaller doses are 400 IU and are available with liquids and capsules.
