B vitamins, a group of water soluble vitamins, are highly essential for maintaining one’s health and general well being. B complex vitamins – which are obtained from natural food sources like eggs, dairy products, meat and poultry – are vital for the metabolism of fats, proteins and carbohydrates. Vitamin B complex consists of eight key B vitamins which include Thiamine, Riboflavin, Niacin, Panthotenic acid, Pyridoxine, Biotin, Folic Acid and Cyanocobalamin.The human body has its own unique compensatory mechanism to release excessive vitamins through urine and feces. However, excessive intake of B complex vitamin supplements (or for that matter any vitamin) can lead to serious health consequences. High amounts of specific B vitamins in the body can unleash a host of symptoms ranging from mild to severe. Some highly probable symptoms of vitamin B overdose are mentioned below.
Top Symptoms Of Vitamin B Overdose
1. Skin Rashes
The appearance of skin rashes is one of the common side effects of vitamin B overdose. The skin will appear flushed, and angry looking welts may appear all over the body. The patient is also likely to complain of an itchy sensation throughout his or her body. The extent to which skin rashes are likely to appear is directly dependant of the intensity of vitamin B complex overdose.
2. Gastrointestinal Problems
This is another common side effect of vitamin B overdose. Taking high dosages of B vitamins can lead to numerous gastrointestinal problems including indigestion, nausea and / or mild diarrhea. People who have a prior history of gastrointestinal problems and older individuals are likely to suffer from excruciating stomach cramps and severe diarrhea after taking high doses of vitamin B.
3. Insomnia
An overdose of B vitamins can initiate or aggravate the problem of insomnia. Vitamin B overdose can interfere with the normal sleep cycle. High amounts of B complex vitamins particularly vitamin B12 in the blood actually works as an energy booster. Sudden spurt in energy levels can affect the normal sleep patterns and lead to insomnia.

4. Numbness Or Tingling Sensation
This is another lesser known side effect of vitamin B overdose. Patients who have been taking high doses of vitamin B over an extended period of time may experience numbness or a tingling / prickly sensation in the extremities. Some patients may also complain of sporadic tingling sensation in the right side of the body. In fact, this tingling or prickly sensation is one of the early warning indicators of vitamin B 12 overdose.
5. Mood Swings
Vitamin B overdose not only affects one’s physical well being but it can have a negative effect on an Individuals mental health as well. Extreme mood swings, restlessness, depression, panic attacks are some the negative side effects of vitamin B overdose. Paranoia, confusion, mental fogginess caused by high amounts of vitamin B complex in the body can worsen mood swings.
6. Hypertension / Hypotension
Vitamin B complex overdose can cause hypertension or hypotension. Excessive levels of vitamin B1 or thiamine in the body can cause hypertension or high blood pressure, while an overdose of riboflavin also known as vitamin B2 can cause hypotension or low blood pressure. Hypertension or hypotension due to vitamin B complex overdose can in the long run affect the normal functioning of the cardiovascular system.
Thanks for the info. I got rid of my B vitamins today. Rash on my back and can’t be anything else. It won’t go away.
How long did it take for the rash to go away?
Two weeks. It was a fungul infection likely from bread molds is what the doctor said. I got a refill recently for the same thing…..if you get the prescription and use a preventive selsun blue shampoo as a bodywash that will go away.
Well like a week but u gotta take the whole prescription, like 2 weeks….
Started B-12 and B complex this week. Itching like crazy, can’t sleep. Will discontinue NOW
Hey can you sleep now and how did you do i also cannot sleep because i took b-100 for 4 days any advice appreciated.
Did a b100 complex and vitamin d treatment plan for 2months. This b complex made first diarrhea, i should’ve stopped immediately but i didn’t suspect it at first. 5 days after i did and it got so severe my right ear had extreme hearing loss, this day i feel better and it feels like it’s healing now. It did help at first but one should’ve stopped right away when symptoms appear. Thankfully the b vitamins are water soluble and are easier derived with the urine from excess consumption.
Hey are you fine i also took b-100 and cannot sleep with vivid dreams, Hope all the excess b are out of you and feeling fine now
Yes, i’m like a normal person again. I’m grateful for that, it also was so scary and for me just experience it, it’s hard to know if it would be permanent so i got very depressed those days.
All of that symptoms happened to me I am not ? coz I went through it and suffered 18 months.
I was always anemic… started large doses of B12 liquid and now over several months my B12 levels are in the 1200’s and now I have a rash on my scalp and down my neck? It itches like crazy and it started about 5 weeks ago and hasn’t let up! I heard yesterday that high levels can cause a rash… I guess I’m asking if this has happened to anyone else and how long after I stop taking for this before symptoms stop? I am also concerned if I may have hurt my health in other ways?!?
Thank you for any feedback!
All of these happened to me I swear to god so many symptoms will appear with u u will not imagin it. So I would like to inform all the people after my experience with vitamin B injections that the deficiency and the excess of it will make the same symptoms so be careful this is ⚠️ warning from a person who suffered a lot (18)months to recover and return back to normal.
And u have to know that the strength of the symptoms dependes on how much the excess reaches in ur body I mean how much the average so the symptoms will be different from person to person but if it is like my case I had very terrified case specially when Vitamin B reached more than 2000 in my body so it was over over over dose so I suffered 18 mothes exactly as they ( Canada and Germany ) doctor said.
How long will it take for your body to get rid of the toxins? Two weeks ago I started taking vitamin b2 supplements but noticed after 5 days that my stomach starting hurting more and more and that I got extremely sensitive to my surroundings (including mood swings). I immediately stopped taking them (that was 4 days ago) but still have mood swings. Especially at the end of the day (after dinner). Seems like it’s my ibs because these mood swings seem to come right after a large meal.
Yes u r very right it makes mood swings and very sensitive to the surrounding and so many things will happen after the excess in the average in ur body.
Yes It happened to me I took 6 injections from B complex b1 , b6, b 12 and from the first night I took the injection it effected my sleep I can’t sleep ever and sweated tooooo much like I was in the gym then the symptoms started to increase but I didn’t recognize that these symptoms were from the injections so I completed it and the symptoms increases day after day , tingling , insomnia, panick attack , general pain in whole body, burning pain , depression , fog thoughts, haunt, gas in my tummy, nervous, not feeling with my fingers and the things thrown from my hands, restless, weakness , effected my memory , cysts begins to appear , my eyes turned to yellow I couldn’t walk I felt that I have rachitis and so many things u can’t imagine it and I did a test for vitamin b and it was 2000 before the last injection but I took the sixth one coz I didn’t notice that these symptoms from the injections so after maybe 2 or 3 days I finished them I recognized that all my complaints from that fuc…. injections so my adventure began with the different specialized doctor and most of them deny my symptoms and said that b complex doesn’t make this and any accsess from it , it will exite by the urine and u have to go to sychology doctor !!!!! ??but I didnt convince with their opinion so I started to email doctors in Canada and Germany and online doctors and fainally I found the answer that my case calls toxicity that mean it effected all organs in my body and specially my nerves so I will be ok after a while and it will take from 12 months to 18 months coz the nerves’ s recovery very slow that means all this case will be a slowly processe and needs a lot of patience.
I suffered a lot I was thinking to kill my self but I didn’t , thanks god and I complete 14 months of suffering then the symptoms started to go a away till I completed 18 months now and my body returns back to normal but thanks god I didn’t take any relaxation tablets or sleep aid medicine so I went through it by strong volition.
Really I was in nightmair so I advise all the people don’t take any vaitamin b without doing a test if there is deficiency u can take it but if there isn’t don’t take it for any reason coz I knew that doctors describe it for the back pain and for a lot of things and after that when the people feel with any symptoms they ( the doctors ) ignore the reasons and Iam very sad that maybe a lot of people kill their self because of that and they don’t know that their symptoms from these fuc….vitamin and they have for sure toxicity from these fuc…. vaitamin b but nobody knows that and now a days in my country doctor in the university told us that they r waiting for the searching about the effection of overdose of vaitamin b And no need to take it before testing the b in ur body because it will make a lot of bad symptoms.
So ,, Any explanation if u need it Iam here because I felt it and suffered from it and I can feedback any one wants help in that fuc…. overdose vitamin B story.
