Vitamin B12 is similar to caffeine in that it works with the nervous system. Caffeine has an effect on the nervous system, while B12 actually works to keep it healthy and firing at top speed. Whilst caffeine increases stress hormones in the body, B12 actually works to bring them down to normal levels.
Vitamin B12 deficiency is another common culprit of fatigue, making it the perfect replacement for your current caffeine addiction.
No, vitamin B12 does not contain caffeine. The only similarity between B12 and caffeine is that they both work with the nervous system. Caffeine works to increase stress hormones and B12 works to bring them down to normal levels. They both produce energy and decrease fatigue, though in very different ways.
There are other studies that found coffee drinkers tend to have higher homocysteine levels which is a surrogate marker for b12 (and folate) deficiency. Overall it seems clear that coffee and caffeine increase excretion of B vitamins, including B 12.
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.
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.
Vitamin B-12 and other B vitamins play a role in producing brain chemicals that affect mood and other brain functions. Low levels of B-12 and other B vitamins such as vitamin B-6 and folate may be linked to depression.
Try to avoid taking your vitamins with coffee or tea
So, wait an hour after your morning brew to take supplements. Caffeine-free herbal tea, on the other hand, contains fewer tannins than regular tea. This beverage may actually increase the absorption of certain minerals such as iron.
Taking vitamin B-12 with vitamin C might reduce the available amount of vitamin B-12 in your body. To avoid this interaction, take vitamin C two or more hours after taking a vitamin B-12 supplement.
[1] People who regularly take medications that suppress stomach acid for conditions like gastroesophageal reflux disease (GERD) or peptic ulcer disease—such as proton-pump inhibitors, H2 blockers, or other antacids—may have difficulty absorbing vitamin B12 from food.
There are 13 vitamins the body absolutely needs: vitamins A, C, D, E, K and the B vitamins (thiamine, riboflavin, niacin, pantothenic acid, biotin, vitamin B-6, vitamin B-12 and folate). Avocados naturally contain many of these vitamins.
One of the best drinks with B12 is milk. One cup of whole milk contains approximately 1.32µg of vitamin B12.
Usually, vitamin B12 deficiency anemia is easy to treat with diet and vitamin supplements. To increase the amount of vitamin B12 in your diet, eat more of foods that contain it, such as: Beef, liver, and chicken. Fish and shellfish such as trout, salmon, tuna fish, and clams.
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.
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.
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 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.
More Serious Effects
B12 injections may contribute to low potassium levels in your body. Though rare, this reaction can cause muscle cramping, extreme fatigue, and an irregular heartbeat.
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.
Fatigue. Megaloblastic anemia due to vitamin B-12 deficiency may lead to a person feeling fatigued. Without enough red blood cells to carry oxygen around their body, a person can feel extremely tired.
Nervous System Reactions
After getting a vitamin B12 injection some people may experience a disturbance to the nervous system. These symptoms may include dizziness, difficulty walking normally, nervousness, anxiety, weakness and uncoordinated movements.
Deficiency of Vitamin B12 can result in hematological changes, neurological and psychiatric problems, which can manifest as irritability, changes in personality, depression, and memory loss [9]. It is also known to worsen depression by excitotoxic reactions caused by the accumulation of homocysteine [10].
Diet. Some people can develop a vitamin B12 deficiency as a result of not getting enough vitamin B12 from their diet. A diet that includes meat, fish and dairy products usually provides enough vitamin B12, but people who do not regularly eat these foods can become deficient.
