Maximum daily amount of B12 one can take
I have tingling and numbness in my left foot and lower left leg. The sensations fluctuate every other day. One day, it is mild and the next day, sensations are stronger. It has been alternating daily like this since last July. My functional medicine doctor had me take a blood test for B6 and the result was very high. So, in March, I stopped taking B6 supplements as my doctor recommended and blood test has shown B6 is within normal limit. Symptoms continue.
I have read in different posts that B12 deficiency can cause neuropathy. I take supplements for nerves from my FM doctor and the total daily B12 I take is 2000 mcg. I am also partial vegetarian as I eat seafood and dairy. I have read posts from people saying that when they have taken more B12, their symptoms have cleared.
Is there an upper limit for B12 daily supplements or B12 shots? Is it possible to take too much B12 and have detrimental effects?
I will ask my doctor for a blood test.
In the meantime, can I safely increase the amount of B12 that I take? If so, is there a maximum amount to take orally?
Thank you.

By the way, today I will be getting another treatment of Laser therapy with my Foot and Ankle doctor, has anyone tried it? Did it help? Thank you

I was showing that my B12 was low several years ago. My doctor did a genetic test which resulted in a switch to Methylated B12. At that time no dosage of B12 was advised. I started taking a high dose. Last year, my blood work up showed my levels were too high. My doctor recommended a Methylated B complex which contains 900mg of B12. Excessive levels are dangerous and can lead to early death.
Ever since I started taking 5000mcg a day of b12 did my nerve pain and sensitive skin go away. I still have pins and needles in my left fingers.

2 ReactionsYou should still have your doctor monitor your levels. I haven't had any additional problems after going with a lower dose. I have the same issues with my hands and feet. I was diagnosed with severe neuropathy last year. Could be a similar issue. Hang in there.
Be sure to take the Sublingual B12, not just B12 tablet…..it bypasses stomach & goes right to blood stream….its a dissolvable 3,000 mcg tab under tongue….take with food.
Can get where all vitamins are in drugstore. 1Xaday….
See my comment below….its necessary to make sure its Sublingual (dissolvable) B12….
2.4 micrograms
So what is the maximum dosage? 3000mcg or what?
