How much molybdenum does a child need? Infant adequate intake (AI) from birth to six months is 2 mcg and for infants seven to 12 months is 3 mcg, which the infant typically receives easily through the intake of human milk.
The answer to your question depends on how much your are taking, how often you are taking them, how long you taken them for, and what other problems may occur. It sounds like you are taking 600 mg (3 200 mg pills) four times per day. This is 2400 mg a day. This is close to the max that I would ever allow a patient to take. By the book, 3200 mg per day is the maximum safe dose.
