After 50 the odds of taking a regular medication go up, and so does the value of a quick word with your doctor before adding a supplement.
The page footer asks anyone on prescription medication, especially for blood pressure, thyroid function or mood, to speak with a doctor first. Our guide on thyroid and blood sugar medication covers the same ground. Several of the ingredients are discussed in relation to blood sugar, thyroid hormones or blood pressure, and the amounts are not published, so risk cannot be measured.
Planned procedures, prostate or heart conditions are further reasons to ask.
Take the ingredient list, a list of every medicine and supplement you use and the question: is any of this a concern for me? Do not stop or change a prescription on your own. If your doctor agrees you can try it, tell them when you start and ask whether any monitoring makes sense.
