Is 2 500 mcg of B12 too much for seniors?
Safety and side effects
Though doses of up to 2,000 mcg of vitamin B12 are considered safe, it's best to speak with a doctor to find out whether taking a supplement is necessary. Most people can fulfill their B12 needs through a nutrient-rich diet.
Additionally, there is no way that you will overdose on B12, so don't worry about taking too much. This number is also higher in certain European countries as well as the fact that vitamin B12's benefits have been speculated to be even more widespread than traditionally thought.
A serum vitamin B12 level between 200 pg/mL and 900 pg/mL is considered normal, but a threshold of 300 to 350 pg/mL is recognized as a marker for a desirable status in the elderly. The laboratory diagnosis is usually based on low serum vitamin B12 levels or elevated serum methylmalonic acid and hom*ocysteine levels.
Although doses up to 2,000 mcg can be used safely to treat vitamin B12 deficiency, you should not take such a high dose if you do not have a deficiency. It is unlikely for high doses to harm most people, but you should not take excessively high doses if it is not recommended by your doctor first.

The amount of vitamin B12 that seniors should take depends on the level of need a given senior has; that's why it's important to involve medical professionals. In general, the recommended daily allowance is 2.4 mcg.
A blood test showing a serum vitamin B12 level between 300 and 350 pg/mL is ideal for seniors, while anything between 200 and 900 pg/mL is considered normal. An elderly person should be getting 2.5 micrograms of B12 per day.
Left untreated, a vitamin B-12 deficiency can lead to anemia, fatigue, muscle weakness, intestinal problems, nerve damage and mood disturbances. The recommended daily amount of vitamin B-12 for adults is 2.4 micrograms.
How do you feel if your B12 is too high?
This is particularly important if you experience any symptoms of high B12 levels in blood, including [9]: Gastrointestinal issues (like nausea, vomiting, and/or diarrhea) Headaches. Tingling in your hands and feet.
Supplementing with vitamin B12 may be important for vegetarians, vegans, and older adults who may not absorb nutrients as easily. There is no upper limit for vitamin B12, and most supplements provide between 500 mcg to 5,000 mcg of B12 daily to meet various nutritional needs [2].
Vitamin B-12 is an important nutrient for older adults. Many older adults are unable to absorb vitamin B-12 from food sources. Additionally, older adults who consume little to no animal products are at an increased risk for deficiency. Consuming foods fortified with vitamin B-12 is important for older adults.
On the other hand, research has demonstrated that oral nutritional supplements containing up to 2,000 mcg daily of vitamin B12 supplements are safe and can be effective in reversing a B12 deficiency.
The usual dose for: diet-related deficiency is 50 micrograms to 150 micrograms, taken once a day. B12 deficiency not caused by your diet is one to two 1,000 microgram tablets, taken once or twice a day – this is usually if you cannot have vitamin B12 injections.
Other medications can also interfere with your uptake of vitamin B12, possibly raising your risk for deficiency. These medications include antacids and peptic ulcer medications, cholesterol-lowering drugs, antiseizure medications, chemotherapy medications, the diabetes treatment glucophage (Metformin) and others.

You cannot overdose on vitamin B12 because any excess you simply pee out. If you get b12 shots, you may experience side effects like dizziness, nausea, and fatigue. It is possible to have elevated B12 levels in blood tests, which may indicate cancer or diabetes.
Can too much B12 be harmful?
Because vitamin B12 is water-soluble, your body usually just absorbs what it needs and excretes the rest in your urine. No adverse or toxic events have been reported in healthy people who get too much B12 from food or supplements.
A common dose of OTC vitamin B12 is 1,000 mcg each day. The risk of vitamin B12 side effects is low — even if you take too much. Your body can only absorb a small amount of vitamin B12 at a time. So any extra leaves your body when you pee.
1000 mcg is about 400 times as much as 2.4 mcg.
Conditions that can increase B12 level include: Liver disease (such as cirrhosis or hepatitis) Myeloproliferative disorders (for example, polycythemia vera and chronic myelogenous leukemia)
Long or prolonged intake of high doses of vitamin B12 can lead to numbness or tingling sensation which usually occurs in the right side of your body. The presence of a tingling sensation or numbness are one of the first signs of vitamin B12 overdose.
