The benefits of Bioactive B12:
-
Two coenzyme forms of B12:
Each 1 ml serving provides 3000 mcg vitamin B12 (120,000% NRV) as methylcobalamin (66.6%) and adenosylcobalamin (33.3%), rather than cyanocobalamin. -
Sublingual liquid, not a tablet:
Take the drops under the tongue and hold in the mouth for 30 seconds before swallowing. The formula is designed for contact with the oral mucosa, rather than relying only on standard digestive absorption. Ideal for anyone but also those with absorption difficulties (MTHFR). -
Tiredness, energy and the nervous system:
Vitamin B12 contributes to the reduction of tiredness and fatigue, normal energy-yielding metabolism, normal psychological function, the normal function of the nervous system, and the process of cell division. Vitamin B12 also contributes to normal homocysteine metabolism. -
Unflavoured reverse osmosis water:
The only other ingredient is reverse osmosis water. There are no flavourings, sweeteners, colourings, alcohol or glycerin. -
Miron® violet glass, 50 servings:
Supplied in a 50 ml Miron® violet glass bottle with a glass pipette. 1 ml is about 13 drops, around one squeeze of the pipette. Once opened, consume within 6 months. Formulated by Certified Nutritionist (Dip.NT) and CEO, Rachel Aceso.

Why no preservatives?

Protecting the quality and potency of our products is crucial, and we do this without adding preservatives.
Instead, we use Miron® violet glass, which protects the liquid from harmful rays of light while allowing beneficial visible violet, non-visible UVA and far-infrared light to enter. The filtered light slows molecular decay, so Bioactive B12 keeps its quality and potency without a preservative in the formula.
