Absorb active B12 rapidly with sublingual methylcobalamin delivery
A liquid vitamin B12 providing 86.5mcg of methylcobalamin per single drop in a purified water base. Methylcobalamin is the active B12 form used in the cytoplasm for methylation reactions, serving as a cofactor for methionine synthase (homocysteine clearance, methylation cycle). The liquid format enables precise dose titration, which is particularly valuable with methylcobalamin because some individuals are sensitive to this form and need to start at lower doses.
The sublingual option (holding under the tongue) bypasses digestive absorption entirely, which is important for the significant percentage of the population with B12 absorption issues (estimated at 10 to 15% of those over 60). The purified water base contains no additives, preservatives or flavourings. The bottle provides 1538 servings per 100ml, making this one of the most economical B12 supplements available on a per serving basis.

† Nutrient Reference Value (NRV*) not established
Purified Water, Methylcobalamin
1 serving = 1 drop | 1538 servings per 100ml
Directions for use:
Take 1 drop per day in water with food.
For sublingual absorption, place 1 drop under the tongue and hold for 30 seconds before swallowing. For those with methylation sensitivities, start with 1 drop every other day and increase to daily based on tolerance.
The liquid format is the preferred starting point for those new to methylcobalamin supplementation, as the 86.5mcg dose allows a gentler introduction than the 1000mcg capsule. Once tolerance is established, some individuals may prefer to switch to the capsule for the higher dose. For those who tolerate it well but want comprehensive B12 coverage, pairing with the Adenosylcobalamin Liquid provides both active forms.
