The association of vitamin B12 (VitB12) with sleep patterns is also not definitive. Some researchers found that VitB12 supplementation is associated with a decrease in sleep duration [15, 21, 22], whereas others found no significant association between VitB12 and sleep duration [23].
Vitamin B12
Many of the studies assessing the impact of B12 on sleep involve small sample sizes or inconclusive findings. Some research suggests a link between higher levels of vitamin B12 and shorter sleep duration, as well as a higher risk of insomnia in certain populations.
There were no interactions found between amlodipine and Vitamin B12. However, this does not necessarily mean no interactions exist. Always consult your healthcare provider.
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.
The results suggest that the use of combined multivitamin supplements, as well as single vitamins, including vitamin B complex, hurts sleep maintenance, causes a higher rate of insomnia, and requires greater use of sleep medicine.
5 Symptoms That Indicate High Vitamin B12 Levels
People may experience frequent episodes of dizziness with no apparent cause. Headaches may be persistent and more intense than common tension headaches.
Because calcium and magnesium compete for absorption, they should not be consumed at the same time. Another reason that it is not good to take calcium at night is because vitamin D should be combined with complete meals.
Other common adverse effects are fever, itching or rash, tingling or numbness of joint, shortness of breath, rapid weight gain, polycythemia, hypokalemia, congestive heart failure, pulmonary edema, and vascular thrombosis.
Vitamin D helps control the sleep-wake cycle.
One way or another, we know that vitamin D is involved in parts of the brain that regulate sleep timing — including hormones that control the sleep-wake cycle. “For example, vitamin D seems to affect how much melatonin is made in the body.
Vitamin B12 (also called methylcobalamin) isn't a stimulant like caffeine. However, maintaining optimum B12 levels plays a key role in preventing you from feeling tired and weak.
At present, B vitamins have been observed to positively impact the prevention of cardiovascular diseases, including hypertension [16]. Higher intakes of vitamin B6, B12, and folate reduce the risk of hypertension and blood pressure in patients with hypertension [17], [18], [19].
Common side effects
Key points about vitamin B12 deficiency anemia
Without enough red blood cells, your tissues and organs don't get enough oxygen. Without enough oxygen, your body can't work as well. Symptoms include weak muscles, numbness, trouble walking, nausea, weight loss, irritability, fatigue, and increased heart rate.
Low vitamin D levels have been associated with insomnia as well as other sleep interruptions by researchers who found the deficiency may double the risk of sleeping less than four hours a night. In addition to supplements, you can increase your vitamin D intake by eating more fresh fish and vitamin-fortified foods.
Talk to your doctor to see if prescription sleep aids are right for you. In elderly individuals, prescription nonbenzodiazepines, such as zolpidem, eszopiclone, zaleplon, and ramelteon, may generally be prescribed as a last-ditch effort to treat insomnia.

You should be able to get all the vitamin B12 you need by eating a varied and balanced diet. If you take vitamin B12 supplements, do not take too much as this could be harmful. Taking 2mg or less a day of vitamin B12 in supplements is unlikely to cause any harm.
There is general consensus that gastric acid–lowering drugs, including proton pump inhibitors (PPIs) and H2-receptor antagonists (H2RAs), and the antidiabetes drug metformin can reduce circulating vitamin B-12 concentrations with prolonged use.
Taking doses of vitamin B-12 might cause:
Vitamin C's stimulating properties may also cause excitability and disrupt sleep quality, leading to insomnia, difficulty sleeping, or unrestful sleep. In addition to insomnia, excessive vitamin C intake can cause side effects such as: Nausea and vomiting. Heartburn, stomach cramps, and digestive issues.
Moreover, we found that vitamin D, folic acid, and vitamin B12 co-supplementation may have the same or even better effect than vitamin D supplementation alone.
B Vitamins
Research has shown that maintaining sufficient levels of Vitamins B3, B5, B6, B9 and B12 may help achieve good sleep. The best food sources of vitamin B include whole grains, meat, eggs, seeds, and nuts, as well as dark leafy vegetables.
In conclusion, our results show that lower vitamin B12 was associated with insomnia symptoms and sleepiness in specific groups of participants. However, further research with objective measurements of sleep is crucial to assess the relationship between sleep and vitamin B12.
Active B12 is generally considered to be the best form of B12 for seniors for several reasons. Metabolically active forms of B12 such as methylcobalamin and adenocobalamin require no further conversion in the body.
Digestive disturbances: Symptoms may include loss of appetite, nausea, and diarrhea. Headaches, rashes, and itching. Numbness or weakness in the arms, legs, and facial muscles.
