Why do you need vitamins?

It is a long-held belief that you don’t need vitamins. Vitamins are supposed to be in our food. It wasn’t until the Great Depression era that we see the idea of taking vitamins. It just so happens that this is the same time that we see rapid changes in production and manufacturing of food in the United States. There are five basic ways, vitamins are produced.

1. Natural - little or no processing from vegetables, minerals or animal sources
2. Natural source - processing found vegetable mineral or animal sources, extracting vitamins from sources.
3. Nature identical - laboratory manufactured nutrients identical in molecular structure and activity and humans to natural nutrients.
4. Synthetic - inexpensive, larger isolated vitamins, laboratory manufactured.
5. Whole food - highly usable and available to the body.
   

Some people have a bad reaction to synthetic vitamins, the body does not recognize a chemically created vitamin. Even if it looks the same under a microscope has a plant-based vitamin also vitamins are not meant to be isolated. Your body sees vitamins as food there for your vitamins should be plant-based like food.

It is also suggested that you look for good manufacturing practices or GMP. Supplement providers are acquired by the DSHEA Act to regulate the quality of the vitamins and other supplements. Supplement providers that meet these standards advertise this on their logos or products. Good manufacturing practices basically mean that what is in one serving of a supplement is exactly the same as another serving from the same bottle or from a different bottle entirely. This is easy to establish when using synthetic vitamins, but whole food plant-based supplements that are the most absorbable are often harder to regulate. It’s very likely your body will notice a difference when you consume high quality nutritional supplements.
