First, one of the most common and most debilitating symptoms of vitamin B12 deficiency is extreme fatigue, 'tired all the time' and in some patients also insomnia.
B12 also plays a role in the production of melatonin, a hormone that helps regulate our circadian rhythms. It is possible that a deficiency of B12 could lead to disrupted sleep patterns.
Vitamin B12 works on the pineal gland, which is responsible for the production of melatonin. The vitamin helps increase the production of melatonin during the nighttime hours, as well as release it earlier, making it easier to fall and stay asleep.
Due to its special role, vitamin B12 aids in the prevention of anemia, which mostly leads to fatigue. Even though the research available about the relationship between vitamin B12 and insomnia remains unclear, some studies² show that elevated levels of vitamin B12 do cause sleeplessness.
Untreated, vitamin B-12 deficiency can lead to neurological problems, such as persistent tingling in the hands and feet or problems with balance. It can lead to mental confusion and forgetfulness because vitamin B-12 is necessary for healthy brain function.
If vitamin B12 deficiency is left untreated, it can cause lasting serious side effects that affect the nervous system and brain. More severe side effects of vitamin B12 deficiency include: Peripheral neuropathy. Degeneration of the spinal cord.
Vitamin B12 helps increase the body's production of melatonin, making it important for regulating sleep-wake cycles. Higher B12 levels have been associated with a lower risk of depression. That makes sense because disruptions in circadian rhythm can be an underlying—and significant—factor for depression.
Vitamin B12 deficiency is linked to a host of sleep problems—from insomnia to sleepiness, not getting enough of this vitamin can wreak havoc on your nighttime routine. Vitamin B12 is also extremely important for our heart health and energy levels.
Vitamin B12, for example, should definitely be taken in the morning. This is because it is important for energy metabolism, which may interrupt your sleep if taken at night.
Omega-3, Vitamin D
A study in the Journal of Clinical Sleep Medicine found the combination of omega-3s and vitamin D from fatty fish like salmon improved sleep in participants. Researchers think it's because of the effect of those nutrients on regulating serotonin.
Research has shown that maintaining sufficient levels of Vitamins B3, B5, B6, B9 and B12 may help achieve good sleep. Best food sources of vitamin B includes whole grains, meat, eggs, seeds and nuts as well as dark leafy vegetables.
It may take a few weeks before your vitamin B12 levels and symptoms (such as extreme tiredness or lack of energy) start to improve. If you have hydroxocobalamin injections to boost your vitamin B12 levels at the start of treatment, the cyanocobalamin tablets may start to work within a few days.
B12 deficiency can cause a variety of symptoms, including fatigue, headaches, depression, pale or yellow skin, mental impairment, and pain and inflammation in the mouth and tongue. Many of the symptoms caused by low B12 levels are not specific to B12 deficiency, which can cause the condition to go undetected.
It's not always clear what triggers insomnia, but it's often associated with: stress and anxiety. a poor sleeping environment – such as an uncomfortable bed, or a bedroom that's too light, noisy, hot or cold. lifestyle factors – such as jet lag, shift work, or drinking alcohol or caffeine before going to bed.
Melatonin plays an important role in regulating human sleep.
If your vitamin B12 deficiency is not caused by a lack of vitamin B12 in your diet, you'll usually need to have an injection of hydroxocobalamin every 2 to 3 months for the rest of your life.
Simply put, how long the B12 shot will last is different for everyone. Though it differs a bit from one person to another, the effects of B12 vitamins usually last around 48 hours to 72 hours after the initial injection.
How long does it take to recover from B12 deficiency? Once you begin treating your vitamin B12 deficiency, it can take up to six to 12 months to fully recover. It is also common to not experience any improvement during the first few months of treatment.
Early detection and treatment is important. If left untreated, the deficiency can cause severe neurologic problems and blood diseases.
Most healthy people who have a well-balanced diet do not need to worry much about vitamin B12 deficiency. However, for those at risk (such as those with celiac disease), measures of blood vitamin B12 levels and, in some cases, preventive therapy with vitamin B12 may be recommended.
If you are low in B12, you will feel weak and tired. Vitamin B12 can give you more energy, boost your metabolism, and help you lose weight.
Bananas also contain fibre and potassium. It helps manage blood pressure, reduce stress, and relieve constipation and ulcer problems. The fruit also helps regulate body temperature. Another fruit that is rich in vitamin B12 is blueberries.
