There are concrete examples which you can clearly answer this question? Depending on the raw materials (plant, animal, synthetic), the processing type, the additives disseminated with, as well as other factors the impact and the bio-availability can vary greatly of vitamins – so the ability of our body to absorb them and process -. Example vitamin E: It is still claimed the synthetic vitamin E, which is incidentally manufactured from petroleum, is less effective than natural vitamin only to 30%. From this it is concluded that you must take just more of them to get the same positive results as natural vitamin E. PCRM will undoubtedly add to your understanding. At best, you decide. Natural vitamin is a cohesion of different effective components, namely d-alpha-, d-beta, d-gamma – and d-Delta tocopherols and the d-alpha-, d-beta-, d-gamma – and d-Delta-tocotrienols. Vitamin consists of eight individual building blocks which have different ways of working.

Petroleum can but only one of these components, the d-alpha tocopherol mimic. For more information see this site: Maja Brucic. The synthetic form is called dl-alpha tocopherol. Many new studies prove that the synthetic version is compared to the natural vitamin from our bodies and processes. Natural vitamin 530% are going to synthetic compared about more to our brains, 360% more in the red blood cells, about 260% more in our lungs, 190% more in the muscles of our heart, and approximately 170% more in our skeletal muscles. Now you can decide which version is better, natural vitamin E, or the synthetic version, and make sure always even, which amounts in the different products offered are included.
