B12 Very Low Effects

While I often address how much B12 is needed by different people, I’m not sure I’ve said it clearly enough to provide an answer when someone is specifically interested in the question of why using B12 has a very low effect, or seems ineffective.

Basically, vitamin B12 levels have different effects on different people. Some people suffer mostly from nerve related issues, others have the most trouble with blood related issues. Low B12 Symptoms. Read More.

What complicates the effectiveness of vitamin B12 is in itself complex. For instance, if you have very little stress in your life you can use a methylcobalamin lozenge of a fairly low dosage and have it help. But if you have a lot of stress in your life then your nerves are probably working overtime and you need more B12 to keep them healthy. In other words, what works for your friend may not work for you.

Additionally, it’s important for you to know how B12 lozenges work. While the bottle the lozenges come in may say to use one a day with a meal, or something to that effect, the reality is that B12 has a very large molecule so if you use a lozenge near meal or snack time the B12 has to compete with the food you’ve eaten, in terms of being used by your body. For that reason, using B12 at a time apart from eating works better.


Inherent in this discussion is “how much” B12 should you be using. As a guideline, it’s good to be aware that a B12 shot a month is the somewhat common doctor’s solution to low B12. To mimic that you would need to use a 1,000 mcg B12 lozenge a day for a month. 1,000 mcg is equal to 1 mg.

For me, that amount of B12 helped, but not as much as more helped. I kept notes so that I could look back and see what was effective. That’s something you need to do, too.

B12 is not dangerous unless you use really really a lot. B12 contains cobalamin, that’s basically what identifies it. Cobalamin is a heavy metal, so if you use really a lot, that can have unwanted results.


Overuse of B12 is less likely than a proper use for your needs, but that doesn’t mean you won’t have painful results. Why? Because if you have blood affected by low B12, then when you start replacing your B12 your blood cells begin to grow healthy and divide the way they are supposed to. That takes a lot of potassium, and very likely you don’t have enough to meet the need. After all our daily need for potassium, without any extra demands, is 4,700 mg.

What are the “painful results”? Basically, too little potassium can result in painful muscle spasms. There are several foods that will solve this problem quickly. Potassium capsules aren’t the answer. Food containing Potassium. Read more.
