People with a prior history of gastrointestinal problems and aged individuals are more likely to suffer from intense stomach cramps and severe diarrhea after taking high doses of vitamin B.
An overdose of vitamin B can initiate or worsen the existing problem of insomnia. When the dose of B vitamins exceeds the normal requirement, it can interfere with the normal sleep cycle.
High doses of B complex vitamins particularly vitamin B12 in the blood acts as an energy booster. Hence, a sudden rise in energy levels can affect normal sleep patterns and leads to insomnia.
In rare cases, people who take high doses of vitamin B for a long period of time may experience extreme numbness or a tingling sensation. In some patients, tingling sensation is experienced mostly in the right side of the body.
This symptom is one of the early warning indicators of Vitamin B12 overdose. One of the other side effects of vitamin B overdose is hypertension or hypotension. When the amount of vitamin B1, also known as thiamine exceeds the normal levels in the body, it can cause hypertension or high blood pressure.
Similarly, when high doses of vitamin B2, usually referred to as riboflavin is taken, it can cause hypotension or low blood pressure. Either of the symptoms due to vitamin B complex overdose can cause a long-term effect on the normal functioning of the cardiovascular system.

Your health care provider may suggest consuming a large quantity of water in a short amount of time to flush excessive B vitamins out of your bloodstream. At the hospital, you may receive intravenous fluid, or IV, to get more fluids into your system. In some cases, induced vomiting is necessary if you ingest a large dose of vitamin B. This practice requires supervision of a health care provider to avoid any adverse effects. This article covers vitamins for women and explains vitamin sources, dietary….
