Avoid an Empty Stomach: Taking certain vitamins, especially iron or multivitamins, on an empty stomach can cause nausea or other digestive discomfort. To avoid this, it’s best to take them with food.
Timing Can Matter: Some vitamins work best when taken at certain times. B vitamins, for example, help with energy production and are better taken in the morning. Magnesium, on the other hand, can support sleep and relaxation, making it a good option for the evening.
Be Consistent: No matter what time you choose, consistency is essential. Taking your vitamins at the same time every day helps create a habit and keeps your nutrient levels balanced over time.
Vitamins and the Best Time to Take Them

Multivitamins: Take them with a meal that includes fat. Morning or lunchtime is ideal, especially if the multivitamin contains both fat-soluble and water-soluble vitamins.
Fat-Soluble Vitamins (A, D, E, K): These vitamins should be taken with meals that contain fat to aid absorption. Healthy fats like eggs, avocado, nuts, seeds, and olive oil are excellent choices.
Water-Soluble Vitamins (B-complex, C): These vitamins dissolve in water and can be taken any time of the day. However, B vitamins are often recommended in the morning because of their role in energy metabolism. Vitamin C can be taken with food to minimize stomach irritation.

Vitamin B12: Best taken in the morning on an empty stomach with water. This helps avoid any interference with sleep later in the day.
Prenatal Vitamins: These should be taken with breakfast or lunch along with water. They often include iron, so pairing them with a vitamin C-rich food or drink (like orange juice) can enhance iron absorption.
Calcium Carbonate: Needs to be taken with food for proper absorption.
Calcium Citrate: Can be taken with or without food, making it a flexible option.
Magnesium: Best taken in the evening or before bed. Magnesium supports muscle relaxation and sleep quality. To avoid digestive upset, take it with food.
Melatonin: This sleep-supporting hormone should be taken 1–2 hours before bedtime to help regulate your sleep cycle.
Vitamin K2: Take with a meal or snack that includes fat. It works well when taken alongside vitamin D for bone health.

Omega-3 Fatty Acids (Fish Oil): These healthy fats are best taken with meals that include fat. Morning or lunchtime is ideal.
Folic Acid (Vitamin B9): Folic acid supports red blood cell production and is essential during pregnancy. Since it’s water-soluble, take it with water at any time of day.
