Multivitamins and specific water-soluble vitamins such as the B group may be taken at any time, with or without food, so taking them first thing in the morning is OK and can help you get into the habit of taking them consistently. Lifestyle factors such as your sleep pattern and stress levels will affect how much you need to eat, so balancing these against the recommended amounts will ensure you get all the nutrients you require. Vitamins are chemicals that cannot be stored by the body, so we need to consume them on a regular basis. The best way to do this is through our diet - particularly through eating a range of fruit and vegetables and healthy fats such as olive oil. Some foods are high in certain vitamins such as C, E, and K, so it's important to include them in your daily meals to keep your body functioning properly. It is also important to consider your daily intake of calories. If you are not consuming enough calories, then you will become vitamin deficient. This can be addressed by increasing your daily intake or supplementing with additional vitamins. It is important to work with a doctor or health professional when doing either of these things to avoid adverse effects. Finally, some studies have suggested that people who start their day with an antioxidant-rich beverage, such as coffee or tea, may be reducing their risk of developing diseases such as cancer and Alzheimer's disease.
