 [ Symptoms ] could multivitamins be the reason im not sleeping  hi  i recently started taking multi vitamins i only take 1 a day though instead of the 3 that they say to specifically this one <link> i normally get to sleep in around 30 minutes however i have noticed for the past 4 days i have taken this i have been restless at night and taking 2+ hours to sleep could it be the cause or should i be taking all 3  thank you [ 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
