1. Collect exact information
Record prescription medicines, over-the-counter medicines, herbal products, vitamins, minerals, caffeine products and occasional remedies. Include the dose and timing.
Photograph the current label rather than relying on an old online description. Formulas and warnings can change.
2. Look for three kinds of overlap
First, duplicated nutrients across products. Second, ingredients that may change the effect or absorption of a medicine. Third, timing conflicts, such as taking certain minerals near a medicine that requires separation.
A website can help organise these questions but cannot know your full medical history.
3. Prepare focused questions
Ask whether the combination is appropriate, whether timing should change, what symptoms require attention and when the plan should be reviewed.
If a new symptom appears after starting a product, record the timing and seek appropriate advice rather than adding another supplement to counter it.
