..I am taking metrapolol twice a day since June. I have always tried to take care of myself. I drink a vega one protein shake once a day and was wondering if there are any interactions with metaprolol? This vega one protein shake does have vitamins and minerals in it as listed: Vitamins A, C, D, E, K,as well as many others. Is it ok to have at mid day since I take the beta blockers at 6:00 am and 6:00 pm to ensure proper absorbtion of beta blockers? The vitamin K is only 60%of daily value so hoping drinking these aren't an issue. Please advise if anyone knows anything
