Should I be concerned if my B12 level is 2000
An abnormally high vitamin B-12 status is anything over 900 pg/mL. This result may suggest liver or kidney problems, diabetes, or certain forms of leukemia.
What happens if your B12 is greater than 2000
A serum B12 level between 300 pg/mL and 900 pg/mL is what is considered normal, according to this article, while results above 900 pg/mL are considered high. If your B12 status is extremely high, it might be a signal that you have a serious issue such as leukemia, diabetes or liver disease.
Why is my B12 at 2000
The most common cause of high B12 in the blood is due to recent ingestion or injection of supplemental vitamin B12. We don't worry about overdosing on B12 supplements because excess can be excreted in your urine. It could also be possibly from your diet if high in animal products such as meat, eggs, and shellfish.
Is 2000 pg mL B12 normal
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 homocysteine levels.
What is an alarming B12 level
Values of less than 160 pg/mL (118 pmol/L) are a possible sign of a vitamin B12 deficiency. People with this deficiency are likely to have or develop symptoms.
What happens if vitamin B12 is more than 1000
The distributions differed between the subgroups with vitamin B12 elevation (p < 0.0001). A significant association between elevated B12 and solid cancers was found from the interval of 750–999 ng/L in cases of nonmetastatic cancer and from the interval 1000–1249 ng/L in cases of metastatic cancer.
What should I do if my B12 is high
Should I be concerned about high vitamin B12 levels Experts agree that proper amounts of vitamin B12 are generally safe to take [9]. Even amounts exceeding the recommended daily amount of 2.4 micrograms usually aren't toxic—as mentioned, what your body doesn't absorb is normally passed as urine [9].
What if B12 is more than 1000
A B12 ≥ 1000 ng/L was associated with the presence of solid cancer without metastases (OR 1.96 [95%CI: 1.18 to 3.25]) and with metastases (OR 4.21 [95%CI: 2.67 to 6.64]) after adjustment for all elevated B12-related causes.
Why is my B12 level so high
The most common cause of high B12 in the blood is due to recent ingestion or injection of supplemental vitamin B12.
How much B12 is too much
Healthcare professionals have not identified an upper limit blood level of vitamin B-12. The body will typically excrete excess vitamin B-12 that a person gets from the diet or via supplements. The body does not absorb vitamin B-12 supplements very effectively.
What to do if B12 is too high
You should stop taking vitamin B12 immediately if you experience any side effects of too much B12. It is important for you to get prompt medical care if your symptoms are severe or are progressively getting worse.
Is B12 level of 1500 too high
Previous studies have chosen a variety of levels to represent high or very high B12 (pmol/l) levels. Some examples include: 664.219; 5131; 700 (high) and 1500 (very high)11; and 601 (high) and 1000 (very high)10. Excess B12 is either stored in the liver, present in the blood without any adverse effects, or excreted.
What does it mean when your B12 is too high
An increased vitamin B12 level is uncommon. Usually, excess vitamin B12 is removed in the urine. Conditions that can increase B12 level include: Liver disease (such as cirrhosis or hepatitis) Myeloproliferative disorders (for example, polycythemia vera and chronic myelogenous leukemia)
How long does it take for high B12 levels to drop
If a person stops consuming the vitamin, the body's stores of this vitamin usually take about 3 to 5 years to exhaust. People should not take high doses of vitamin B12 as a cure-all, but otherwise the vitamin does not appear to be toxic; consuming excess amounts of B12 is not recommended.
