 Timing is everything when it comes to taking your vitamins and supplements. So we put together a guide to help you maximize the powerful health benefits that come from taking them at the right time. Morning. Probiotics. Probiotics are best taken in the morning on an empty stomach. When the stomach is empty, digestive activity is quiet and stomach acid and pH balance are relatively low, increasing the chances for the helpful microorganisms to thrive. Iron. Iron is best absorbed in the morning on an empty stomach. Caffeine, dairy, and calcium can negatively affect absorption, so it's best to avoid these for several hours after taking iron. Multivitamins. Take multivitamins with your first meal in the morning. As multivitamins contain both water and fat-soluble vitamins, be sure to include some healthy fats with your meal for optimal absorption. B-complex vitamins. Taking B-vitamins with breakfast helps to boost your metabolism and convert your food into energy, which can be used throughout the day. Vitamin C. Vitamin C is best taken in the morning to support the immune system and boost energy levels. Vitamin C is a water-soluble vitamin that lasts only a few hours in the bloodstream, so if your formula recommends more than one tablet per day, take it in divided doses with meals to get the full benefit. Noon. Co-Q10. Co-Q10 is best taken at lunchtime with the meal that contains dietary fats. Avoid taking Co-Q10 late in the day so it does not disturb your sleep. Vitamin D. Vitamin D is best taken with the meal that contains dietary fats. It's possible that Vitamin D can negatively affect sleep, so lunchtime is a good time to get your Vitamin D. Iodine. Iodine is not stored in the body, so regular intake is needed. Kelp tablets taken with lunch may boost mid-day energy levels. Vitamin K. Vitamin K is best absorbed along with the dietary fats and ideally should be taken during the middle of the day. Avoid taking Vitamin K if you are taking Coumadin or any anticoagulant prescription drug as Vitamin K can interfere with the effects of this medication. Night. Fish oil is important to support many aspects of health. Fish oil is best taken with a main meal such as breakfast, lunch, or dinner to aid absorption. Calcium. Calcium aids nerve transmission and muscle function. To get the full benefit, take Calcium in the evening along with Magnesium. Magnesium. Magnesium has a calming effect on the muscles and nervous system and may aid in restful sleep. Magnesium works synergistically with Calcium, so take these together either as individual supplements or in a combined formula.
