3. Vitamin B12 is helpful for certain neurological disorders.
Elderly adults plagued with certain neurological disorders can benefit from Vitamin B12 supplementation. Many older adults diagnosed with Alzheimer’s or dementia are really just B12-deficient and make dramatic recoveries when their low levels of B12 are handled.
There is oftentimes a misdiagnosis because vitamin B12 deficiency symptoms closely match symptoms of those diseases. Vitamin B12 injections are sometimes called for, and high doses have been shown effective for people with these conditions.
There’s even some evidence that taking a full spectrum B-complex supplement can be helpful for Alzheimer’s patients.
