Natural vs. Synthetic
You can classify vitamins in different ways. We've already talked about water-soluble vitamins and vitamins that dissolve in fat. Another classification is natural and synthetic. Natural vitamins, as the name suggests, occur in nature and synthetic vitamins are made, actually imitated, in a laboratory. Sometimes there is no difference in that for the body. In the past, for example, aspirin was made from willow bark, but nowadays all aspirin comes from a laboratory. Only when you can make a 100% identical laboratory variant, the body will see no difference and absorb the active ingredient in the same way.
The fact that this is not always the case can be seen in vitamin E. In its natural form, this vitamin is absorbed much better by the body than the synthetic version. However, sometimes there is a difference in absorption.
Last but not least: there can be big differences between one synthetic preparation and another for suppliers use different substances to produce supplements. In particular, making supplements with a long shelf life is a technique not all manufacturers have mastered yet. The result: pills that have no or reduced effect.
