Gut Bacteria Produce Vitamins


Synthetic Nutrients Supplements are Not That Good.

vitamins: natural, synthetic
Multivitamins may be unnecessarily wasting your money. Except a few positive effects, research has been unable to find any clear benefits of using synthetic nutrient supplements. High doses of vitamin E even showed increased risk of death from all causes (1). In another reports, there was a warning that administration of beta carotene, vitamin A, and vitamin E may increase mortality. And further study is needed for the potential effects of vitamin C and selenium on mortality (2).

Gut Bacteria Provide Vitamins

Beneficial bacteria in the gut help us by break down and digest foods, after which they secrete enzymes. They also produce some nutrients that we cannot make ourselves, such as vitamins K2, B1, B2, B3, B6, B12, folic acid, and various amino acids. Therefore, good bacteria can provide lots of nutrients. Getting good bacteria (Probiotics) is more natural and you don't even need to worry about an overdosing (3).
