However, vitamin B12 deficiency is known to be involved in the pathophysiology of depression, which can commonly be associated with insomnia [19].
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.
Some research indicates that higher amounts of vitamin B12 link to shorter sleep duration and a higher risk of insomnia. A 2007 study suggests it may also affect the 24-hour biological processes that help a person go from wakefulness through drowsiness to sleep.
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.
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.
“Take water-soluble vitamins on an empty stomach with a glass of water,” recommends Dr. Perez-Gallardo. And since it can be energizing, Dr. Perez-Gallardo says that the best time to take vitamin B12 is in the morning, so it won't affect your sleep.
Vitamin C and B12
It's not advised to take vitamin C and vitamin B-12 at the same time, says Litt. That's because high doses of vitamin C can reduce the amount of vitamin B-12 that's absorbed and metabolized by the body, she says. Be sure to take vitamin C at least two hours after vitamin B-12.
Vitamin B12 is considered an important brain and nervous system micronutrient and is often used for anxiety. It helps to ensure normal function for your nerves, which can help combat physical symptoms of anxiety.
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.
One Possibility: Supplement Allergies
Thus if you're otherwise healthy but still continue to feel tired after taking a B-12 supplement, it could be a sign of a mild allergic reaction. If a rash, difficulty breathing or swelling coincides with taking your dose of B-12, get to the doctor right away.
Vitamin B12 deficiency can have distressing neuropsychiatric symptoms. It can have an etiological role in clinical presentations like depression, anxiety, psychosis, dementia, and delirium, requiring screening of at-risk populations.
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.
Taking Vitamin B-12 Before Bed
There is no specific time of day recommended when you should take vitamin B-12 supplements, as there is no clinical evidence demonstrating a significant difference between taking vitamin B-12 in the morning or at night.
Magnesium. Magnesium was the featured nutrient in a study published in the Journal of Research of Medical Science, which found that adding a supplement in elderly participants improved the symptoms of insomnia and sleep quality. Nuts, beans, seeds, tofu, bananas and whole grains are all good sources of magnesium.
B12 acts as a cofactor in synthesis of neurotransmitters such as serotonin and dopamine, thus B12 deficiency affects mood, emotions and sleeping and can lead to psychiatric disorders.
Mental Health Benefits of B12
B12 is needed to form memories and to focus and concentrate. Low B12 levels are associated with depression. This makes sense when you consider that B12 is required for the formation of the mood-boosting neurotransmitters serotonin and dopamine.
When Vitamin B12 and folate supplements are combined, they enhance the production of serotonin and dopamine. The two vitamins both play important roles in regulating and maintaining a good mental health state. It is important to note that older people are more susceptible to deficiency of vitamin B12.
Interactions between your drugs. No interactions were found between Vitamin B12 and Vitamin D3. However, this does not necessarily mean no interactions exist. Always consult your healthcare provider.
Vitamin C and B12
Airey, some studies have shown that Vitamin C could break down Vitamin B12 in your digestive tract, reducing your B12 absorption. As a result, he says you want to wait at least two hours before taking Vitamin C with your Vitamin B12.
Can I take magnesium and vitamin B together? Yes, as B vitamins and magnesium don't compete for absorption inside your body. Indeed, many supplements combine them as a way of simplifying how you monitor your intake.
Vitamin B12 is an essential nutrient. Fish, shellfish, meat, eggs, and dairy products are good sources of vitamin B12. The amount that should be consumed on a daily basis is called the recommended dietary allowance (RDA). The RDA is 2.4 mcg daily for people 18 years and older.
Vitamin B12 is an essential nutrient that must be ingested daily because our bodies don't naturally produce it. B12 is important for many enzymatic processes, such as helping turn the food you eat into usable energy. The recommended daily amount for B12 is 2.4 mcg for adults.
