The timing of when you take some supplements matters. Get the most out of your supplement by taking it at the times that maximize absorption and effectiveness.
1. Iron
You can better maximize your iron supplement’s benefits when you take it at certain times, such as:
- On an empty stomach: Studies suggest iron is best absorbed when taken without food. Try taking it at least 30 minutes before a meal or two hours after a meal.
- With vitamin C: Pairing iron with vitamin C may enhance the absorption of iron.
- Separated from supplements or drugs containing calcium or phosphorus: Supplements that contain calcium or phosphorus and calcium-containing antacids can interfere with iron’s absorption. Take your iron at least two hours apart from these.
2. Vitamin B12
Understanding when and how to take vitamin B12 can help you optimize absorption and benefits:
- Take it in the morning for energy: Taking B12 in the morning or early afternoon can help boost your energy. This is because B12 helps your body convert food into energy.
- Take it on an empty stomach: Taking it on an empty stomach helps improve absorption.
- Avoid taking it with certain foods or beverages: High amounts of vitamin C (found in citrus fruits) can reduce B12’s absorption if consumed at the same time.
- Space it apart from medications: Separate B12 and medications such as metformin and proton pump inhibitors by at least four hours to ensure optimal absorption.
3. Vitamin D
Taking vitamin D in the morning is recommended to achieve the best results. This is because evening intake may reduce melatonin production. Melatonin and vitamin D work in opposition, so taking your vitamin D too late may impact your sleep quality.
Your body produces vitamin D when you are exposed to sunlight. Since it’s challenging to get sufficient vitamin D from food alone, consider supplementing during the winter months when sunlight is limited, especially if you have limited sun exposure.
