B12 Deficiency May Cause: Fatigue Depression Poor memory Neurological symptoms High homocystiene levels Poor circulation A B12 supplement specifically engineered for performance that fuels your healthy lifestyle. Essential Source strips were designed to have a large surface area. As a result, they absorb almost instantly leaving less room for product waste. With most other sublinguals, consumers have the ability to chew and/or swallow too early, causing under utilization of the ingredients. Another reason they are so popular is just the convenience. It is easier to carry the tiny cassette than some other sublinguals, liquid drops, or sprays. Since B12 is often used for energy, people can take them any time they are in need. This product was manufactured in a GMP approved facility.

Strip B12 Advanced Delivery Oral B12 Sublingual B12 100% 100% Q. Why should I take B12 Strips instead of a pill? A. When you take a vitamin in pill form, any B12 present is absorbed by tiny proteins in the stomach and intestines that bind B12. As a result, only a small percentage of any form of B12 makes it into your bloodstream. B12 Utilization Cyanocobalamin B12 Methylcobalamin 100% 100% Q. Why should I choose Methylcobalamin over Cyanocobalamin B12? A. Methylcobalamin is the most efficient form of B12. Before Cyanocobalamin can be properly utilized by the body, it has to be stripped down in a time consuming, multi-step process. Methylcobalamin is already the most highly reduced form, allowing a high level of benefit.
