Vitamin B12 is an essential nutrient, but one that is eventually depleted if dietary sources are inadequate or absorption mechanisms are compromised. B12 deficiency is especially common in the elderly, vegetarians, and as the result of a variety of malabsorption syndromes, including those caused by the use of acid-blocking medications. Oral B12 therapy is as effective as injections as long as sufficient amounts are taken. Karuna's B-12 Liquid is a high-potency formulation using methylcobalamin, preferred by many over cyanocobalamin.
Suggested use for adults: One-half to one dropper daily (approximately 521-1041 mcg), preferably with a meal, or as directed by your health care practitioner. Hold the solution under the tongue for a few moments before swallowing.
