Vitamin B12
As a general rule of thumb, take your B vitamins in the morning or with a meal. 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.
Because vitamin B12 absorption requires a healthy and functioning stomach, pancreas, small bowel and enough IF (Intrinsic Factor), anyone, regardless of what they do or do not eat, can be at risk of a vitamin B12 deficiency. A B12 deficiency, if left untreated, can cause irreversible brain damage, or worse.
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.

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.
Vitamin C and vitamin B12 are water-soluble vitamins, which means you need water to absorb them. “Take water-soluble vitamins on an empty stomach with a glass of water,” recommends Dr. Perez-Gallardo.
Take them with or without food, with one exception: You'll absorb B12 better with a meal. If you also use vitamin C, put 2 hours between them. Vitamin C can keep your body from using B12.
The lowering effects of vitamin B12 together with folic acid on blood pressure have been reported in intervention study in adults. However, no study has reported the association of vitamin B12 by itself with systolic or diastolic blood pressure in children or in adults.
B12 deficiency is also characterised by neurological problems, such as hallucinations, paranoia and insomnia. B12 needs to interact with acid in the stomach to be bio-available in the rest of the body. So problems with indigestion and heartburn can be linked to B12 deficiency.
A lack of vitamin B12 can cause neurological problems, which affect your nervous system, such as: vision problems. memory loss. pins and needles (paraesthesia)
A few people experience gastrointestinal issues, such as bloating or diarrhea, from getting too much B-12. In rare cases, too much B-12 from a combination of diet and supplements can cause blood clots. You could also be allergic to a B-12 supplement and experience itching and rashes.
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.
You may be too exhausted even to manage your daily affairs. In most cases, there's a reason for the fatigue. It might be allergic rhinitis, anemia, depression, fibromyalgia, chronic kidney disease, liver disease, lung disease (COPD), a bacterial or viral infection, or some other health condition.
So does vitamin B12 give you energy? While B12 doesn't directly provide energy, it does give the body the tools it needs to convert food molecules into energy. Getting the recommended daily amount of B12 can therefore help ensure that the body is able to make the energy it needs to do everything you need it to do.

There are very few reasons to take supplements, but getting enough of this vitamin may be one of the most important. Vitamin B12 may not be high on your nutritional radar, yet it is essential to some of the body's most important functions, like forming red blood cells and maintaining nerve function.
