While some people assume that dementia is a natural (and unavoidable) part of the aging process, some people are unlucky enough to suffer from premature dementia. This is often caused by deficiencies of one kind or another, specifically vitamin B12. If you’re starting to feel foggy, even as a young person, you may need to boost your vitamin B12 intake, which is very easy to do. This can be an effective remedy for both young and old people who need a brain enhancer, and B12 supplements are readily accessible in the majority of health food stores around the world.
