Question 1

hi is there any possible link between vitamin b12 and a bit high estrogen levels?

Accepted Answer

Nothing definitive: A few studies have been done which show influence in both directions: post-menopausal women who took vitamin B12 (and other) supplements showed increased estradiol levels. Women with surgical removal of uterus/ovaries were given estradiol and showed increased B12 levels! The exact connection is unclear. Eat a balanced diet including meat/dairy products; vegetarians may need B12 supplements.

Question 2

my vitamin b12 level is 283 pgml.my body can't absorb b12 orally.so i'm taking 1500 mcg methylcobalmin inj/day.how long can i take them b4 toxicity ?

Accepted Answer

Depends: on your individual situation. You should get levels rechecked on a regular basis to determine this.

Question 3

what causes high vitamin b12 levels?

Accepted Answer

Intake + Absorption: Vitamin b12, aka cyanocobalamin, is common in a huge variety of foods; low intake rare. However, none of us absorb B12 directly. Instead, the cells of the upper ⅔ of the stomach which secrete hydrochloric, hcl, acid also produce & secrete a protein, called intrinsic-factor, which binds b12. The small intestines absorb intrinsic-factor with whatever B12 is bound, & the B12 is thereby also absorbed.

Question 4

is a vitamin b12 level of 195 healthy?

Accepted Answer

: On most laboratory levels, your vitamin B-12 is far too low and needs to be corrected.  Contact your doctor and have this handled.

Question 5

is a vitamin b12 level of 141 serious?

Accepted Answer

: It is mild deficiency, not quite serious but you definitely need B12 supplement. Although the lower limit of normal is around 200 but most people have level much higher than that and we often advise B12 supplement if there is a suspicion of B12 deficiency by clinical history, symptom or sign although the level is not below 200 yet. Take care.

Question 6

my vitamin b12 level is 258. is that low?

Accepted Answer

: B12 is considered low below 190/200. Borderline is 200-300. I usually suggest a level above 400. Would follow up with MD as to cause. Dietary  i.e. vegan, as it is found in meat poultry, fish, dairy, and fortified food. underlying small bowel/ ilieal disease  or other cause.

Question 7

is a vitamin b12 level of 141 considered bad?

Accepted Answer

: Not bad, it might be low depending on the units being reported on, normal ranges are anywhere between 160-950 pg/ml or 118- 700 picomoles/l. Your ordering doc will be best to place your result in context and further advise in case indeed on the lower side.

Question 8

vitamin b12 levels came back 1500!! should i be concerned?

Accepted Answer

Needs clarification: The first thing I would do is check the lab result...perhaps a decimal point is out of place as a normal result is in the 200 to 600 pg/ml range. Are the units correct ... pg (picograms) per milliliter. Some medications can affect B12 levels. It would be unusual to have such a high level and no other signs of liver/kidney disease or cancer.

Question 9

will taking a vitamin b12 complex help with low energy levels?

Accepted Answer

Vitamin B12 : It may help with low energy levels depending on the cause. It is always best to consult a physician to determine the cause of fatigue, low energy, weakness, asthenia, etc. Before self-medicating with vitamin supplements. While vitamin B12 is safe, the cause for feeling tired may have to do with something unrelated to it.

Question 10

what happens if my vitamin b12 levels are above normal, is that ok?

Accepted Answer

Nothing: Vitamin B12 is a water-soluble vitamin and is easily excreted. It is nearly impossible to achieve toxic levels even with extreme levels of intake. Deficiencies are much more clinically relevant.
