Could I still take a B12 injection if it is expired by 6months?

Could I still take a B12 injection if it is expired by 6months?

Yes, safe, but...: The expiration date on meds is the time limit that the dosage potency is guaranteed. After that time, the potency may be less (but often is not). It is the rare drug (some types of tetracycline) that become toxic if outdated. Nevertheless, a pharmacy can not dispense, and a physician is not supposed to administer a medicine beyond its expiration date. ...Read more

I Just took a B12 injection. How long does it stay in your system.

The answer: depends on your own individual metabolism and your dietary habits. If you eat a lot of processed foods, chances are the chemicals contained within these products will interfere with your intestinal absorption of this vitamin. Injections bypass that problem. Most injections last about a month on average. The amount of B12 in your body also depends on how much is stored by your liver . ...Read more

What is the difference in how B12 is metabolized between injections and pill forms?

What is the difference in how B12 is metabolized between injections and pill forms?

Muscle vs GI: The injection goes into a muscle and is directly absorbed into the blood. This is the preferred route for people with absorption problems. The oral route or pill form may not be well absorbed if there is stomach conditions- like pernicious anemia, or intestinal issues like crohns. These patients due to their inflammation would benefit from an intramusclar shot. ...Read more

I'm wondering how much time it will it take for vit B12 injection to show its results?

Rapid: If you are B12 deficient, the anemia will improve and reticulocyte count rise within a week. If your have a neurologic deficit, you'll notice an improvement in a week or two. If you're being given B12 as a placebo or part of a "natural healing" scheme, there's no answer as it's not benefiting you beyond the power of suggestion. Be sure you understand why and whether it's long-term. ...Read more

B12 level came bk low 199. Is 50mg tabs x2 a day enough to get this to normal level? Or injections be better?

Find out why: If you're low because you're a vegan / vegetarian, your medicine will help and you should reconsider your lifestyle. If you have pernicious anemia and can't absorb the stuff, you'll need injections. If another cause (gut disease, fish tapeworm), your phyiscian should try to detect it. ...Read more

B12 level is 217 pmol/L. Been symptomatic for 2 years and fighting for injections. Do you consider this low?

B12 level is 217 pmol/L. Been symptomatic for 2 years and fighting for injections. Do you consider this low?

YES: Some experts suggest anyone with a B12 level below 450 who has symptoms suggestive of B12 deficiency be treated. Some people will respond to high doses of oral or sublingual B12 but if that dose not increase your levels you should get injections. I don't see why you should have to fight to get these.

Which form of B12 is best for shots/injections and why?1. Cyannocobalamin2. Methylcobalamin3. Hydroxicobalamin

Which form of B12 is best for shots/injections and why?1. Cyannocobalamin2. Methylcobalamin3. Hydroxicobalamin

Usually Methyl but..: One thing is clear- Cyano is worst- it has small amounts of cyanide the body must detox & convert it to an active form; little is converted. Methyl is the active form, esp. good for those with MTHFR mutations & neurological symptoms & best for most. Some do better with Hydroxo. Experts agree Hydroxo better than Cyano but haven't seen many comparisons of Met vs. Hydr. See http://tinyurl. ...Read more

I was told by a number of nurses that i must have a script to get a B12 injection. why is this and is it true?

It depends: Vitamin B12 is an essential vitamin which is critical in formation of blood in the human body. So if you are Anemic, you should get blood tests done to find the cause. B12 is sometimes the cause for anemia...many times it is due to Iron deficiency. Either way you need to get your CBC done to check your hemoglobin(Hb level) and see a physician who can guide you in treating your anemia(if needed). ...Read more

Had vit b12 defic 8 years ago was on injection program every 3month. Moved away new dc test b12 was normal cancelled program 4years ago now symp again?

B 12 levels: If I understand your question correctly, you think your B 12 may be low again. It is a very simple lab test any doc or nutritionist can order. Please have your B 12 level checked. If low, ask your doc about taking SUBLINGULAL B 12. The B 12 you swallow is much less effective. Peace and good health. ...Read more

Should a vegetarian take B12 injection daily?

No: If you can absorb B12 normally, this should be parted of your regular oral nutritional supplement. Vegetarians may also do well to take iron, vitamin D and a few others. If and only if you have a problem absorbing B12, for example if you've had pernicious anemia, do you take monthly B12 shots. ...Read more

Where can you get B12 with lipotropics injections?

Where can you get B12 with lipotropics injections?

Methylated B12: Is more bio-available, easier to absorb, than B 12. Taking a SUBLINGUAL B 12 that melts under the tongue can be used in place of injections. EGCG capsules (from green tea) can be used in place of lipotropics injections. Nothing replaces the need for lifestyle changes such as healthy diet and exercise program. Please see doc for guidance.

Can I still use b12 injections that were left in the heat?

Please do what your: Doc says. If you use sublingual B 12 I don't see any necessity for shots for the average person. If you swallow B 12 you will still need shots because oral B 12 is not nearly as well metabolized as sublingual. Peace and good health. Extreme heat may destroy B 12. ...Read more

Are there any conditions where B12 injections would help but oral/sublingual B12 wouldn't???

Not many: It used to be thought that the only mechanism for B12 absorption involved intrinsic factor such that injections were necessary with pernicious anemia or any condition that caused a deficiency in intrinsic factor. However, now it is known that oral B12 in very large doses can be absorbed even in that situation to prevent deficiency. I would guess an absent small bowel would do it. ...Read more
