More than 40% of adults and elderly people are deficient in Vitamin B12.
B12 deficiency is strongly linked to brain atrophy, which means decreased brain mass and loss of neurological function.
Vegetarians are especially prone to B12 deficiencies(1). But even if you eat meat, your body can have a hard time to absorb Vitamin B12.
The most common reason for B12 deficiency is because of;
- Low stomach acid
- Acid-blocking drugs
- Excess alcohol consumption
The Importance of Vitamin B12
It’s crucial for nerve health and production of red blood cells that carries oxygen through your body.
Elder people with low levels of Vitamin B12 are more likely to suffer from brain shrinkage. This worsens cognitive function and develops dementia.
Vitamin B12 deficiency also affects your energy levels and mood. It’s common for those who suffer from mania and bipolar disorder.
Deficiency happens over time, commonly as stomach acid levels decreases.
Choosing the Right Form of Vitamin B12
When you decide to buy Vitamin B12, be aware that there are different forms with different quality. Just like Magnesium.
This is the cheapest and lowest quality form. You’ll find it in most supplements.
The body can’t absorb cyanocobalamin directly, it has to convert and activate in order to be useful.
Cyanocobalamin is a synthetic chemical put in supplement just so they can label and say it contains Vitamin B12. Avoid this form.
This form is an “activated” form of vitamin B12 for immediate use. It’s absorbed more effectively and has no cyanide molecule.
This form is often recommended for chronic fatigue, but also for neurological aging.
