ADVANCED DELIVERY SYSTEM

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 spays. Since B12 is often used for energy, people can take them any time they are in need.*

B12 Deficiency may cause: • Fatigue • Depression • Poor Memory • Neurological Symptoms • High homocystiene levels • Poor circulation*

B12 UTILIZATION Cyanocobalamin B12 Methylcobalamin B12 100% 100%

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.*

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.*

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.*
