Fråga: "A woman took a total of ten capsules of "Ripped Fuel", a so called "thermogenic formula" bought at a health club, in very early pregnancy. Is there any risk for fetal damage?"

Sammanfattning: "The reported contents of the product ""Ripped Fuel""; phenyl alanine, carnitine, caffeine and chromium are not known to be harmful to the pregnant woman or her fetus in moderate doses. However, we recommend that this type of product be avoided during pregnancy, as its usefulness is doubtful and its safety cannot be guaranteed."

Svar: According to the manufacturer a capsule of "Ripped Fuel" contains 125 mg phenylalanine, 50 mg L-carnitine, 100 ug chromium and 455 mg of guarana extract with a content of 100 mg caffeine. Phenylalanine and carnitine are amino acids, with no known teratogenic properties, at least not in moderated doses, as above (1, 2). One-hundred mg of caffeine is found in a strong cup of coffee and is not harmful to the fetus. A large intake of caffeine during pregnancy, more than 6-8 cups of coffee daily, have been associated with an increased risk of abortion and low birth weight, with smoking and alcohol intake as possible confounders (1). One-hundred ug of chromium is within the recommended daily intake of 50-200 ug, pregnant or not (3).

Also, intake of a possibly harmful substance in very early pregnancy, is usually said to lead to a all-or-none response, with either an early spontaneous abortion or a normal pregnancy.
