I have been reading that some people who stutter have tried taking large doses of Vitamin B1 and that it has helped them stutter less. I wonder if this really works, or if it is just a placebo effect. Because of the following information, I sure hope people who try this are under a doctor's care to make sure that they don't become sick because they have upset the balance of other B vitamins in their system.
"The B vitamins all work together in a complex. Taking too much of a single B vitamin, such as vitamin B1, can cause an imbalance in the other B vitamins. In severe cases, the imbalance may cause deficiencies in the other B vitamins, which can cause a wide variety of symptoms. Deficiencies in several of the other B vitamins, such as B3, B6 and B12, can cause feelings of fatigue and tiredness, along with skin irritations and rashes. Deficiencies in B6 and B12 can lead to anemia, causing very pale skin and muscle weakness. Vitamin B12 deficiencies can also cause neurological symptoms, including numbness or tingling in the hands or feet.
Dosage: The Recommended Daily Allowance, or RDA, of vitamin B1 for adults over the age of 19 is 1.2 mg per day for males and 1.1 mg per day for females. The doses for children and infants are smaller, down to 0.2 mg per day for infants younger than 6 months old. People with vitamin B1 deficiency may be prescribed larger doses to treat their condition. Vitamin supplements often contain 50 to 100 mg of vitamin B1. Because vitamin B1 is generally nontoxic, these doses are almost always safe."
