As you get older, vitamin B12
can reverse mental slowdowns
or just help you get a good night's sleep.
B12 also plays a role in melatonin production. Melatonin is the hormone responsible for letting you get a good night's sleep. As we age, the body is less efficient at making this hormone. B12 supplementation has helped some older adults sleep better.
On the opposite end of the life spectrum, children who have asthma may benefit from vitamin B12 as well. Weekly injections of 1,000 mcg or daily oral supplements of 1 to 3 mcg improved their condition and resulted in less shortness of breath.
AIDS patients typically have low levels of this vitamin. This can be used as an indicator that overall nutritional status is low and that attention needs to be given to intake of all nutrients. In the laboratory, vitamin B12, in any form, reduces replication of HIV. This is a hopeful treatment yet to be tested in humans.
Several studies show that B12 dramatically increases sperm counts in men whose counts are low. The vitamin also jump-starts sperm's action, increasing motility rates.
People with tinnitus, that constant ringing in the ears, are often deficient in vitamin B12. Supplementation diminishes the irritating ringing for some people.
