Supplements Could Harm You: Doctor's Urgent Warning

Dr. Amir Khan, a TV doctor, has issued an urgent alert for individuals taking specific medications, warning that certain supplements can interfere with their effectiveness. He emphasized that consumers often assume natural supplements are safe but stressed that this is not always the case, particularly when combined with prescribed drugs.

Supplements like St. John's wort, commonly used for low mood, are identified as major culprits. Dr. Khan explained that St. John's wort can interact with antidepressants, the contraceptive pill, blood thinners, and even post-transplant medications by altering liver drug processing.

Turmeric or curcumin supplements, popular for inflammation, pose a bleeding risk for those on blood thinners like warfarin. Magnesium supplements can also hinder the absorption of antibiotics such as tetracyclines and fluoroquinolones, as well as thyroid medication like Levothyroxine. Experts suggest a four-hour gap between taking magnesium and Levothyroxine, and specific timing for antibiotics.

Additionally, calcium supplements can reduce the absorption of certain antibiotics and levothyroxine. Vitamin K, found in some supplements, can interfere with warfarin, affecting clotting risk. Even grapefruit juice can interact with statins. Dr. Khan's core message is to inform your doctor about all supplements taken to avoid potential adverse interactions.
