Why ‘normal’ B12 levels may not protect your brain long-term

Why vitamin B12 matters more than you think

A fascinating new study has highlighted the importance of maintaining optimal Vitamin B12 levels, suggesting it's time to rethink what we consider “sufficient” in blood tests.

What did the study find?

Researchers examined 231 healthy older adults, to see how their Vitamin B12 levels affected their brain health. Although all participants had B12 levels considered within the normal range, people with lower active B12 levels were found to have:

Slower thinking and visual response times: taking longer to process information and respond to visual cues.

More brain changes: more white matter lesions (which are linked to cognitive decline, dementia, neurodegenerative disease).

It's well known that severe B12 deficiency can cause neurological issues such as memory loss, cognitive decline, and nerve damage. But this new research suggests even "normal" B12 levels might not be sufficient for optimal brain health. Ensuring adequate B12 intake is crucial, especially as we age.

Could you benefit from more B12?

Even if you eat a healthy diet, factors such as ageing, digestive issues, and modern lifestyle stress can reduce your ability to absorb B12.

Supplementing with the right forms can help prevent subtle neurological changes before they become a problem.

The best forms of B12 for optimal health

✅ Methylcobalamin – The active, bioavailable form of B12 that is easily absorbed and used by the body.
✅ Adenosylcobalamin – Another natural form of B12 that supports mitochondrial function and cellular energy.

Unfortunately, many supplements instead contain cyanocobalamin, a poorly absorbed, synthetic form of B12. 

Pollution Protection Multivitamin contains both active forms of B12 to ensure maximum effectiveness, helping to safeguard brain health, support nerve function, and promote longterm vitality.
