Recent studies found that vitamin B12 and folic acid supplements decreased homocysteine levels in subjects with vascular disease and in young adult women.

Carry out suit young adults you want a nutritional B12 supplement?

It is generally accepted that older adults are at greater risk of developing a vitamin B12 deficiency than younger adults. One study, however, suggests that the prevalence of vitamin B12 deficiency in young adults may be greater than previously thought. This study found that the percentage of subjects in three age groups (26-49 years, 50-64 years, and 65 years and older) with deficient blood levels of vitamin B12 was similar across all age groups but that symptoms of vitamin B12 deficiency were not as apparent in younger adults. This study also suggested that those who did not take a supplement containing vitamin B12 were twice as likely to be vitamin B12 deficient as supplement users, regardless of age group. However, people who did not use supplements but did eat fortified cereal more than 4 times per week appeared to be protected from deficient blood levels of vitamin B12. Better tools and standards to diagnose vitamin B12 deficiencies are needed to make specific recommendations about the appropriateness of vitamin B12 supplements for younger adults.
