Unique Properties

Patient One B-12 Liquid supplies 1000 mcg of B-12 in the metabolically active methylcobalamin form for optimal bioavailability and retention. Common B-12 supplements that use cyanocobalamin require the body to take extra steps to transform it into a usable compound. Our liquid promotes accelerated absorption and complete B-12 delivery. This is important because B-12 absorption from food or supplements declines with age. In fact, 15% of people aged 60+ are deficient in vitamin B-12. Vegetarians and vegans also face higher risk of B-12 deficiency. Patient One B-12 liquid is easy to measure in the provided calibrated glass pipette and features a pleasant cherry flavor to promote patient compliance.

Key Ingredients

B-12 as Methylcobalamin:

Methylcobalamin is a highly bioactive and bioavailable form of vitamin B-12, shown to be easier to absorb and utilize than the commonly used synthetic cyanocobalamin form which must be converted into the active methylcobalamin form to deliver wellness benefits. Methylcobalamin accounts for most B-12 circulating in plasma. Methylcobalamin B-12 supplies methyl groups for protein and DNA synthesis while supporting circulation, neurotransmitter production, and cellular energy production. B-12 also optimizes healthy homocysteine levels, promoting overall cardiovascular wellness.


  • A cohort study investigated the association between cognitive decline and B-12 and folate nutritional status. In the 1648 participants in the study, researchers found that low vitamin B-12 status was associated with more rapid cognitive decline.
  • In a placebo-controlled, double-blind, randomized crossover study of 50 vegetarians with vitamin B-12 deficiency, researchers found that those taking 500 micrograms of supplemental vitamin B-12 appeared to experience improved arterial function when compared with the placebo group. Researchers concluded that B-12 supplementation is a novel strategy for promoting healthy arteries in vegetarians with low B-12 levels.
