Top Summary
- What happened: An NHS doctor, Dr. Amir Khan, advises against taking certain supplements with tea or coffee.
- Why it matters: Incorrect supplement timing can significantly reduce their absorption and effectiveness, wasting money.
- What changes for people: Individuals need to adjust when they take supplements like iron, vitamin D, and magnesium.
- Who is affected: Anyone who regularly takes supplements and consumes tea or coffee.
Iron Supplements: Morning is Key
Dr. Amir Khan, a general practitioner, highlights the importance of timing for supplements.
He stresses that taking iron supplements in the morning, on an empty stomach, is crucial for optimal absorption.
Avoid tea, coffee, or magnesium when taking iron. Instead, pair it with Vitamin C and water for better results.
"You want to take them first thing in the morning on an empty stomach and with vitamin C for better absorption. Don't take them with tea or coffee or magnesium because that can reduce absorption," said Dr. Khan.
Vitamin D, Omega-3, & the Importance of Fat
Fat-soluble vitamins like Vitamin D and Omega-3 require dietary fat for proper absorption.
Take these supplements with food, ideally during breakfast or lunch.
This applies to other fat-soluble vitamins such as vitamins A, E, and K.
- Vitamin D: With breakfast or lunch
- Omega-3: With breakfast or lunch
- Multivitamin/Vitamin K: With breakfast or lunch
Magnesium: Evening Relaxation
Magnesium is best taken in the evening, according to Dr. Khan.
It has a relaxing effect and can potentially improve sleep.
Take it an hour or two before bed.
Creatine: Take it Anytime
Good news for creatine users! Creatine can be taken at any time of the day.
"That's an easy one. You can take it whenever, wherever. So that one's fine," the doctor said.
By following the correct supplement schedule, your body can utilize them more effectively, maximizing their benefits.
What to Watch Next
Further research into supplement timing is always ongoing. Consult with your doctor or a qualified healthcare professional before making any changes to your supplement routine, especially if you have underlying health conditions or are taking other medications.
