 [ Symptoms ] when i gave birth i tore very very badly urine is now inside my vaginal canal [ Disease ] multivitamins taking at 100 the daily value should not have an effect on sleep but this item is not just a multivitamin it also has other ingredients like green tea extract quercetin and piperine that may affect your sleep i would call the company to see if sleep is a side effect unfortunately supplement companies are not held the same standard as drugs so they may not have the studies to show
