• As much as 40% of Americans are low or deficient in this essential nutrient. Read this article: Why Everyone (Not Just Vegans) Should Be Taking Vitamin B12

• Vitamin B-12 deficiency leads to megaloblastic anemia, a fatigue-ridden condition where red blood cells don't develop properly and can't carry oxygen efficiently.

• B-12 deficiency is a serious problem that can cause fatigue, weakness, constipation, weight loss, depression, poor memory, asthma, vision problems, and low sperm count.

7. Keeps You Looking and Feeling Young

Aging happens when your cells begin to wear and tear, and they age faster when your DNA doesn’t replicate correctly. Many factors can affect DNA replication, like free radicals, toxins in the blood, high blood sugar, and high levels of omega-6 fats in your diet. B12 supports DNA health, thereby keeping your cells younger. And when your cells are young, you look and feel young too.

Low quality B12 formulations can have serious problems when it comes to their effect on the body, their purity, and of course what's known as their 'bio-active' abilities.

What is Vitamin B12?

Although most of us simply know vitamin B12 as the B vitamin responsible for energy production, it's important to understand that vitamin B12 is actually a catch-all term for a class of vitamins known as cobalamins -- cyanocobalamin, hydroxocobalamin, methylcobalamin, and adenosylcobalamin -- and they are not equal in their benefits.

Cyanocobalamin is a synthetic vitamin found in low-end supplements and fortified foods. It is not included in the Revitalize B12 formula. Ours is the perfect balance of the three most effective forms of B12, each offering its own contribution to the complete cobalamin regimen.

Hydroxocobalamin is a natural form of B12 that the body assimilates and utilizes slowly throughout the day, providing lasting effect.

At the same time, methylcobalamin and adenosylcobalamin are what's called "coenzyme forms" of B12, and your body puts them to efficient use quickly.

Dosage

The serving size of Revitalize B12 is 12 drops. If done 2x per day, that would be 500 mcg of these high quality forms of B12. At that dosage, the 60 servings would last 30 days. (For more on a 500 mcg daily intake of B12 read this.)

If it is possible to test your B-12 levels and set a dose level, perhaps higher than the serving size in Revitalize B12, in consultation with a qualified healthcare professional, that would be ideal.

Who Should Take B-12 Supplements?

Most everybody should be taking B12 supplements. Those who eat meat do get some B12 by eating animals who have been given B12 supplements. Since meat eating comes with numerous health hazards, it is cleaner and simpler to stick to a plant diet and take your B12 supplement, yourself, rather than taking it via an animal's supplementation regimen. 

The Framingham Offspring Study in 2000 found that 39% of the average population is low (ranging in deficient to “low”) in B12. The study showed no statistically significant difference between old people and young people. More interestingly, there were no statistically significant differences in B12 between people who consumed meat and people who didn’t.
