You need to know this about vitamins

Experts recommend taking vitamin C in the morning to avoid sleep disruption due to its stimulating effect, omega-3 fatty acids after lunch to improve absorption and minimize side effects, iron on an empty stomach for best absorption, B-complex vitamins during the first half of the day to aid in energy production and metabolism, magnesium 15 minutes before bedtime to help with sleep and muscle relaxation, and calcium during meals, especially with vitamin D-rich foods to enhance absorption.
