However, since the body does not produce omega-3s itself, we need to get them through our diet or through supplements. Oily fish like salmon and tuna are good sources of EPA and DHA, but most people do not consume the recommended amount of omega-3 daily. If this is your case, fish oil supplements can help you get there.

Vitamine B12

This essential vitamin contributes to the formation of DNA and red blood cells, but it can be obtained through food. Foods rich in B12 include eggs, milk, meat, poultry and seafood. Although most people get enough food, 10-30% of the elderly do not get enough vitamin B12. If your food intake is insufficient or if you are over 50, you can get B12 by taking a multivitamin or foods fortified with vitamin B12.

Mélatonine

Getting enough sleep is important, since sleep affects almost every tissue and system in the body – from the brain, heart and lungs to metabolism, mood, and resistance to disease. Studies have shown that melatonin supplements can help reduce the effects of jet lag and restore the circadian cycle. Melatonin can also prolong the total sleep time in people with disturbed sleep schedules, such as shift workers, and reduce the time it takes to fall asleep for people with sleep disorders.
