User Reviews for vitamin b12

I feel relaxed when I take this supplement on a regular basis.

I used to get terrible leg cramps. A blood test showed I was low in Vitamin B. A doctor recommended taking 1 x 2500 mg. of sublingual Vitamin B12 tablets daily. It's worked wonders. I have not had leg cramps since - a year or two now.

After 15 yrs of fatigue, 500mg B12 gummy helps. I also get an energy boost from separate B2 50mg 2x day with meals, which reduces migraine episodes. Adding on 500mg soy lecithin 2x day (don't tolerate sunflower version) with meals has lifted all my fatigue.

I take B12 for fatigue. I take 6000-10000 mcg per day (spread thruout the day). If you don't feel a difference your dosage is probably too low. No side effects and don't feel as tired in the afternoon. I also have been sleeping better at night.

I HAVE JUST STARTED TREATMENT WITH B-12 SHOTS FOR ONE EVERY DAY FOR 7 DAY'S ,NOW I TAKE B-12 QUICK DISSOLVED. I DON'T FEEL MUCH CHANGE,BEEN ONE MONTH TAKING IT DAILY .

Taking for two months B12. 2500 MCG sublingual by Solgar. Within two weeks I could feel some changes. It has been two months and I am feeling amazingly better. Much more energy, depression has substantially lifted. A side effect has been that my sweet cravings are decreasing. I am able to have none or a little and feel satisfied. I have lost almost 10 lbs, I attribute this to less sugar and overall increased energy level allowing for, if not exercise, at least a new zest for life! I never expected results anywhere near what I have experienced. Amazing.Read More Read Less

for tic delorul or facial neuralga , it relives the dicomfort.

Went to the Dr because my wife was worried than I was lacking concentration, my mind would wander etc. When tested for Vit B12 it was very low,192 which is below the recommended range. Started taking 5000 mcg of Vit B12 daily and my memory and concentration improved dramatically in less than a month. In addition I was less fatigued and no longer required midday naps. Further blood testing showed my Vit B12 level going from 192 to 750. Overall I feel mentally like a young man again.

I took a whole tablet of B12 (1000mcg) for two days and half of it for another 2 days. I ended up with my whole left side from top to toe numb and tingling, I was dizzy, had balance issues when standing and walking, got extreme fatigue, confusion. I spent 3 days in the hospital with doctors trying to figure out what was wrong with me and as the B12 I had taken left the body during the next week, the numbness got a little better. I saw a chiropractor to get help with the nerves and it helped a little. I did plenty of stretching. Just as I was mostly better, I decided to double check by taking half a tablet, and most of the above side effects came back for a couple of days.Read More Read Less

I rely on b12 supplements for better energy, better mood, and clarity of my mind. I'll consume a 5000mcg supplement before speaking engagments, social gatherings, and places where I know I need fully engaged attention.

I'm a 63 yo male and had been suffering from fatigue for several years. I have been taking (generic) Prilosec for many years. My wife's doctor mentioned that Prilosec reduces the ability to absorb vitimin B 12 and suggested I try a supplement. I started on Sublingual B-12 5000 mcg about a month ago and within two days noticed a huge difference... No more need for afternoon naps and I feel about 10 years younger. It's working for me...

I have/had very low B12 but doctors missed this early and it developed into very bad Peripheral Neuropathy. I have been having B12 injections for nearly 5 years now but still have the condition which has gotten worse over time. I also take various other vitamins to try and help my condition. I have seen various doctors and one professor over time and they admit they cant help any more as it is degenerative. My condition was caused by eating very bad chicken resulting in food poisoning.

Dr ordered 2500 mcg. Within four day I was suffering depression and hyper activity. Discontinued on fifth day.

make me feel extremely feerish and nauseaious
