Synthetic vitamins are created in a laboratory with many man-made ingredients. Most of these ingredients do not absorb well into the human body which is why they can come out in the urine in bright yellow. Most of our sewer systems are full of vitamins!! This can be a big waste of time and money.
Whole food vitamins are very different. They utilize foods that you might find in the grocery store like peas, brussel sprouts, radishes, beets and kale. Then, these are ground down into a fine powder and put into capsules or pills using careful methods to safeguard the nutritional make-up of each vitamin. The whole food ingredients are then added to make a complex formula that might include whole food extracts, animal tissues and concentrates, botanicals, whole food isolates and a small amount of synthetic ingredients if absolutely necessary.
