BioActive B12 "Full Spectrum" - is a high-quality VEGAN Vitamin B12 complex utilizing the three most important bioavailable forms of B12. This advanced formula includes highly desirable ingredient forms that do not require conversion in the liver in order to be available for use by your cells. METHYLCOBALAMIN -- Methylated Form: Essential for supporting MTHFR deficiency, healthy methylation and normal homocysteine levels. Supports energy production, mood & cognitive function.* ADENOSYLCOBALAMIN -- Mitochondrial Form: An active "coenzyme" form of B12 that is utilized directly in B12-dependent enzyme reactions within the body. HYDROXOCOBALAMIN -- Storage Form: Readily converts to biologically active Vitamin B12 when your body needs it, playing a unique role in supporting detoxification. From your blood cells to your nerves and down to your DNA, Vitamin B12 is a critical vitamin for the health of your body. We've carefully formulated this highly bioavailable, vegan BioActive B12 to include ALL 3 bioavailable forms of B12. Bioactive simply means that the precious B12 has already been converted into a form that your body can utilize immediately. With these specialized bioactive forms, the B12 does not need to be converted in order to be available for use by your cells (conversion can be especially problematic for people with MTHFR issues such as MTR, MTRR, COMT as well as other gene defects and mutations). Did you know that both vegan and non-vegan individuals commonly suffer from B12 insufficiency? If you’re omnivorous, you may get some B12 from meats, dairy and eggs (often not nearly enough as we no longer consume organ meats); however vegetarians and vegans have a much more difficult time. If you’re a strict vegan, studies have confirmed that you’re likely to be insufficient in B12, unless you’re supplementing regularly. While rates of B12 insufficiency are much higher in vegetarians and vegans than in omnivores, that doesn’t mean it’s rare in omnivores. Approximately 1 in 20 omnivores are B12 insufficient. B12 deficiency is also more common in people with gut problems because that often decreases intestinal absorption (including taking OTC drugs which block stomach acid). Older adults are also at risk as stomach acid levels decline as we age, which makes it difficult to cleave the Vitamin B12 from its protein bound form in food. The consequences of Vitamin B12 insufficiency are extremely serious and sometimes irreversible (nerve damage for example). Vitamin B12 is water soluble - our bodies are unable to store it for very long. Ultimately, it's very important that you are getting enough B12 in your diet every day - and the easiest, most bio-available method is to take this supplement consistently. Methylcobalamin - Assists methylation, supports brain & nerve health, circulatory & immune systems, and normal homocysteine levels. Adenosylcobalamin - Supports muscle recovery, mitochondrial structure and function, as well as the structure and function of the delicate myelin sheath. Hydroxocobalamin is a precursor form of Vitamin B12 converted in the body to both Methylcobalamin and Adenosylcobalamin. This form of B12 helps support mood, an overall sense of well being, energy production, clear thinking and detoxification.
