Frequently Asked Questions

  • Vitamin B12 is a byproduct of bacterial fermentation—not synthesized by plants or animals. While it's commonly found in animal-based foods like eggs and meat, this formula sources B12 through a clean, fermentation-based process, making it completely suitable for vegetarians. Since plant-based diets typically lack sufficient B12, health authorities recommend that vegetarians and vegans supplement.

  • The ability to absorb B-vitamins naturally decreases with age, and various indicators of cognitive impairment are associated with reduced B-vitamin levels. The elderly in general suffer from a reduction in sense of taste and thus appetite and may use many acid reducing medicines that predispose them to B12 deficiency. Vitamin B12 is an incredibly difficult nutrient to assimilate and digest as well as one of the most important vitamins for a broad range of bodily functions including optimal functioning of the nervous system, normal DNA and RNA synthesis, optimal energy production and healthy blood integrity.

  • Health experts estimate that one in five adults is deficient in one of the B-vitamins. Absorption of vitamin B12 is a complex process, which can lead to B12 deficiency. Keep in mind that even in a healthy person’s gastrointestinal tract, there are always other proteins and vitamins competing for absorption alongside vitamin B12, which is so large and complex that it very often must struggle for entrance into the bloodstream.

  • Studies have found no confirmed reports of toxic side effects from heightened dosages of vitamin B12. However, you should only take Isotonix Advanced B-Complex as directed on the bottle.
