There is a reason the 750ml format works for B12 water. The recommended daily allowance for an adult is 2.4 micrograms; the typical 750ml ORA B12 bottle carries 2.5 to 5 micrograms. One bottle, one day, no calculation. That is the whole proposition.
What the format is good for
- Daily desk-side hydration for a working adult — finishes through the day without thinking about it.
- Gym and training sessions where the bottle sits next to the bench or in the bag.
- Vegetarians and vegans who want a low-friction B12 source.
- Adults over 50 supplementing reduced food-based B12 absorption.
- Anyone on long-term acid-reflux medication where B12 absorption is compromised.
What it is not
B12 water is not a treatment for clinical deficiency. If a recent blood test shows a B12 level below the normal range, the right correction is tablets in cycles or injections under a doctor — water carries too small a per-bottle dose to recover from real deficiency in a useful timeframe. For maintenance and prevention, it is the easiest format to keep up. For correction, it is not the right tool.
What to check on the bottle
- Microgram dose per bottle — should be printed.
- Form — methylcobalamin is the body-ready form, cyanocobalamin requires conversion.
- No added sugar — a sugar-loaded B12 water is missing the point.
- Mineral profile — a B12 water should also work as a mineralised drinking water, not just a vitamin delivery.
